Fish and Wildlife Service, Interior.
We, the U.S. Fish and Wildlife Service (Service), determine endangered species status under the Endangered Species Act of 1973 (Act), as amended, for Brickellia mosieri (Florida brickell-bush) and Linum carteri var. carteri (Carter's small-flowered flax), two plants from Miami-Dade County, Florida. The effect of this regulation will be to add these plants to the List of Endangered and Threatened Plants.
This rule becomes effective October 6, 2014.
This final rule is available on the internet at http://www.regulations.gov and at http://www.fws.gov/verobeach/. Comments and materials we received, as well as supporting documentation we used in preparing this rule, are available for public inspection at http://www.regulations.gov.

Why we need to publish a rule. Under the Act, a species may warrant protection through listing if we find that it is an endangered or threatened species throughout all or a significant portion of its range. Listing a species as endangered or threatened can only be completed by issuing a rule. We will also be finalizing the designation of critical habitat for Brickellia mosieri and Linum carteri var. carteri under the Act in the near future.
This rule will finalize the listing of Brickellia mosieri and Linum carteri var. carteri as endangered species.
The basis for our action. Under the Act, we may determine that a species is an endangered or threatened species based on any of five factors: (A) The present or threatened destruction, modification, or curtailment of its habitat or range; (B) overutilization for commercial, recreational, scientific, or educational purposes; (C) disease or predation; (D) the inadequacy of existing regulatory mechanisms; or (E) other natural or manmade factors affecting its continued existence. We have determined that Brickellia mosieri and Linum carteri var. carteri meet the definition of an endangered species based on Factors A, D, and E.
Peer review and public comment. We sought comments from six independent specialists to ensure that our action is based on scientifically sound data, assumptions, and analyses. We invited these peer reviewers to comment on our listing proposal. We also considered all other comments and information received during the comment period.
Previous Federal Action
Please refer to the proposed listing rule for Brickellia mosieri and Linum carteri var. carteri (78 FR 61273; October 3, 2013) for a detailed description of previous Federal actions concerning these plants.
Summary of Comments and Recommendations
In the proposed rule published on October 2, 2013 (78 FR 61273), we requested that all interested parties submit written comments on the proposal by December 2, 2013. We also contacted appropriate Federal and State agencies, scientific experts and organizations, and other interested parties and invited them to comment on the proposal. Newspaper notices inviting general public comment were published in the Miami Herald.
Peer Reviewer Comments
In accordance with our peer review policy published on July 1, 1994 (59 FR 34270), we solicited expert opinion from six knowledgeable individuals with scientific expertise that included familiarity with Brickellia mosieri and Linum carteri var. carteri and/or their habitat, biological needs, and threats; the geographical region of South Florida in which these plants occur; and conservation biology principles. We received responses from all six of the peer reviewers we contacted.
We reviewed all comments received from the peer reviewers for substantive issues and new information regarding the listing of Brickellia mosieri and Linum carteri var. carteri. The peer reviewers generally concurred with our methods and conclusions, and provided additional information, clarifications, and suggestions to improve the final listing rule. Peer reviewer comments are addressed in the following summary and incorporated into the final rule as appropriate.
(1) Comment: One peer reviewer commented on the lack of discussion related to the threat of herbivory from invertebrates, both native and nonnative, and noted that Brickellia cordifolia, a north Florida species, experiences considerable damage on an annual basis from a not-yet-identified, leaf-boring-type arthropod. The reviewer also noted the possible threat of unnaturally high herbivory from deer, rabbits, and other vertebrates, as well as threats associated with feral hogs, both of which he stated are threats throughout most of Florida.
Our Response: We appreciate the information provided; however, biologists monitoring Brickellia mosieri in Miami-Dade County have not observed any significant damage to the species from invertebrates or vertebrates, native or nonnative. In addition, another peer reviewer noted that deer no longer occur in the areas where these plants exist, and rabbits occur only sparingly, and not in all areas. Based on the information available at this time, the Service does believe that predation poses a threat to Brickellia mosieri.
(2) Comment: One peer reviewer noted that two specimens of Brickellia
mosieri (filed as B. eupatorioides and annotated by K.A. Bradley as B. eupatorioides var. floridana) in the collection at the Fairchild Tropical Botanic Garden Herbarium indicate that the historical range of this species probably extended north of South Miami. Based on these specimens, the reviewer stated that the historical range is better characterized as extending from approximately Coconut Grove to Florida City, while allowing that these observations may have been included Start Printed Page 52568with those described as not giving accurate or precise location information under “Historical Range” in the proposed rule.
Our Response: We appreciate the information provided. The Service was aware of one of these samples (by Buswell in 1947 from a pineland south of Coral Gables), which was referenced by Bradley and Gann (1999, p. 16), and incorporated into their approximation of historical range (South Miami is less than 3.2 km (2.0 mi) southwest of Coral Cables). However, we were not aware of the second sample (by Small in 1912 from pinelands near Coconut Grove). Based on this new information, we agree that the northern extent of the historical range is more appropriately characterized as Coconut Grove. We have incorporated the revised text and related changes (i.e., calculations of range contraction) in the Background and Determination sections in this final rule.
Comment: One peer reviewer noted that an understanding of these plants' reproductive biology, especially their floral biology, pollination, and breeding systems, is especially critical to helping them recover more robust numbers. A second peer reviewer had a similar comment regarding the need for additional study related to seed dispersal, pollinator mechanisms, and augmentation and reintroduction studies. The first reviewer noted that the effects of habitat conditions on the reproductive allocation of both plants has not yet been quantified, and that individuals in smaller, more isolated, and/or degraded pine rockland habitat fragments have lower reproductive rates than counterparts in larger, more well-maintained pine rockland sites, leading to the likely loss of genetic diversity represented in those low-quality sites over time.
Our Response: We agree and had incorporated similar statements in our discussion of Habitat Fragmentation and Effects of Small Population Size and Isolation (under Factors A and E, respectively, in the Summary of Factors Affecting the Species section) in the proposed listing rule.
(4) Comment: One peer reviewer requested further identification of the area identified as “Rockdale Pineland Addition” in Table 2 of the proposed rule (78 FR 61273; October 3, 2013).
Our Response: According to the Florida Natural Area Inventory's (FNAI) Florida Conservation Lands data layer (September 2013 version), the area known as Rockdale Pineland consists of two parcels: Rockdale Pineland (approximately 26 acres, owned by the State of Florida and managed by Miami-Dade County), and the Rockdale Pineland Addition (approximately 21 acres, owned and managed by Miami-Dade County). Rockdale Pineland Addition surrounds Rockdale Pineland, like a buffer. The Linum carteri var. carteri occurrence is within this “buffer,” along the edges of the abandoned FEC Railroad tracks, adjacent to pine rockland habitat.
(5) Comment: One peer reviewer noted an apparent discrepancy between the occupancy of Brickellia mosieri on Federal lands (U.S. Coast Guard (USCG) and National Oceanic Atmospheric Association (NOAA) lands in the Richmond Pinelands), as described in Table 1 and in the Federal section under the discussion of Factor D, The Inadequacy of Existing Regulatory Mechanisms, in the proposed rule (78 FR 61273; October 3, 2013).
Our Response: The discrepancy was related to the difference between how Brickellia mosieri occurrences were reported in Table 1 (i.e., specific to managed area and owner) versus how we evaluated whether an area was considered occupied (i.e., described at the habitat patch level). We considered contiguous pine rockland habitat to be the same habitat patch, regardless of where ownership boundaries were located within it. A habitat patch was considered occupied if the species occurs within its boundaries, although the species may not have been observed throughout the entire patch. Thus, NOAA and some USCG lands are considered occupied by Brickellia mosieri because an extant population occurs within the same habitat patches (Martinez Pineland and University of Miami, respectively). That said, we have revised the language in the discussion of Federal regulations under Factor D in the Summary of Factors Affecting the Species section to explain this distinction.
(6) Comment: One peer reviewer noted that Lygodium microphyllum (Old World climbing fern) is not likely a threat to Brickellia mosieri and Linum carteri var. carteri as it primarily occupies wetland habitats, and is not known to invade pine rockland habitat.
Our Response: We agree and have removed this language from our discussion of nonnative plants under Factor E in the Summary of Factors Affecting the Species section.
(7) Comment: One peer reviewer stated that the U.S. General Services Administration property within the Richmond Pinelands Complex should be more thoroughly surveyed for both plants, especially Brickellia mosieri.
Our Response: The lands referenced are now owned by the U.S. Army Corps of Engineers. However, we agree with the peer reviewer and would encourage and support such a survey being conducted. The Richmond Pinelands Complex represents the largest remaining group of contiguous fragments of pine rockland habitat outside of Everglades National Park (ENP), and the Service hopes to cooperatively engage all landowners, including Federal agencies, to survey, manage, and conserve this area.
(8) Comment: One peer reviewer specifically supported our rationale for the proposed listing determination, which focused on a more qualitative assessment of threats, rather than some form of population viability analysis, due to limited data available, especially in relation to population response to stochastic events and long-term disturbances. The reviewer also noted that guidelines developed for medium-to-large size animals do not work well for herbaceous plants, which could have 1,000 individuals concentrated in a single site, making the species vulnerable to a single event of human or natural origin.
Our Response: We agree, and thank the reviewer for this comment.
Comments From States
The two plants occur only in Florida. We received no comments from the State of Florida regarding the listing proposal. We note, however, that one peer reviewer was from the Florida Forest Service, Florida Department of Agriculture and Consumer Services; those comments are addressed above.
During the first comment period, we received two public comment letters directly addressing the proposed listing. Both commenters suggested technical corrections to sections of the proposed rule pertaining to the Background and Summary of Factors Affecting the Species, related to scientific names, species biology, and citations, to include additional information and correct minor errors. We did not receive any requests for a public hearing, nor did we receive any comments on the listing rule during the second comment period. The comments are appreciated and have been incorporated into the appropriate sections of the final rule. The remaining comments we received are grouped below into two general issues.
Issue 1: Habitat
(9) Comment: One commenter noted that the sandhill community does not occur in Miami-Dade County (per FNAI 2010), and suggests that mesic flatwoods Start Printed Page 52569would be a more appropriate description of an intergrade community with pine rocklands on the northern Miami Rock Ridge.
Our Response: We thank the reviewer for this comment, and acknowledge that there is an apparent discrepancy between the described pine rockland-sandhill community association on the northern Miami Rock Ridge (per Snyder et al. 1990, p. 257, as well as FNAI 2010, p. 63) and the described extent of sandhill within Florida (does not extend into Miami-Dade County; FNAI 2010, p. 40). Based on review of the FNAI community descriptions, we agree that the classification of mesic flatwoods most accurately describes the community into which pine rockland merges in northern Miami-Dade County, and have incorporated this information in the Background section.
(10) Comment: One commenter noted that, in our discussion of natural forest communities (NFCs) in Miami-Dade County (in the Local section under the discussion of Factor D, The Inadequacy of Existing Regulatory Mechanisms of the proposed rule (78 FR 61273; October 3, 2013)), tropical hardwood hammocks include rockland hammocks.
Our Response: We agree. In this instance, we used the term “tropical hardwood hammock” in keeping with the terminology used on Miami-Dade County environmental Web sites to describe this type of habitat within NFCs and Environmentally Endangered Lands. Because of this, and because pine rocklands are the focus of the discussion, we believe it is suitable to retain the existing wording in this section.
Issue 2: Threats
(11) Comment: One commenter stated that Pine Shore Pineland Preserve burned in a wildfire on April 8, 2013, resulting in improved habitat conditions. Because of this, and in relation to this commenter's previous cited personal communication (in the proposed rule (78 FR 61273; October 3, 2013)), the commenter believes that this population of Brickellia mosieri is no longer the most endangered.
Our Response: We appreciate the information provided and have removed the subject sentence related to the habitat condition and status of Brickellia mosieri on Pine Shore Pineland Preserve from the Summary of Factors Affecting the Species section.
(12) Comment: One commenter indicated that the threat of mountain biking at R. Hardy Matheson Preserve has been mitigated (as opposed to remedied, as stated in the proposed rule (78 FR 61273; October 3, 2013)) by the installation of fencing. This commenter also stated that habitat succession has increased since mountain bikers have been fenced out, which has not benefited habitat for Linum carteri var. carteri.
Our Response: We appreciate the information provided and have incorporated it into the Summary of Factors Affecting the Species section.
Summary of Changes From the Proposed Rule
Based on information we received in peer review and public comments, we made the following changes:
In the Background section:
(1) We made the following five changes to scientific names: Revised the names of three plants to reflect the accepted taxonomy per the Integrated Taxonomic Information System (ITIS), added a subspecies designation and corrected the common name of one plant to represent the intended pine rockland subspecies, and deleted one plant from the vegetation list to prevent potential taxonomic confusion.
(2) We corrected one citation (Bradley and Gann 1999), which was missing a digit in the year.
(3) We revised the description of pine rockland's natural community associations on the northern Miami Rock Ridge, changing the association with sandhill to an association with mesic flatwoods.
(4) We revised the historical range of Brickellia mosieri, extending the northern extent from “South Miami” to “approximately Coconut Grove”, to reflect new information regarding herbarium samples. Related to this change, we revised our calculations of the contraction of historical range, from more than 13 percent to more than 30 percent.
(5) We included additional information on the flowering response of Brickellia
mosieri to fire.
In the Summary of Factors Affecting the Species section:
(6) We deleted a sentence related to the habitat condition and status of Brickellia
mosieri on Pine Shore Pineland Preserve, as it was no longer applicable.
(7) We revised wording related to the occurrence of Brickellia mosieri in the Richmond Pinelands and specifically on lands managed by USCG and NOAA.
(8) We made the following changes to two scientific names: Revised the name of one plant to reflect the accepted taxonomy per ITIS, and changed the name of one plant in two places to correct a typographical error.
(9) We removed a sentence referencing the potential future threat of Lygodium microphyllum, since this plant is unlikely to pose a threat to pine rockland species due to its strong association with wetter habitats.
(10) We revised and included additional information on the threat of mountain biking and habitat conditions at R. Hardy Matheson Preserve.
(11) We revised a sentence regarding IRC's Brickellia mosieri reintroduction site, replacing “George and Avery Pineland” with “one private site.”
Please refer to the proposed listing rule (78 FR 61273; October 3, 2013) for the description of Brickellia mosieri, its taxonomy, and its suitable climate. Below we present updated summaries of information in the proposed rule, and new information based on peer review and public comment, related to its habitat, historical and current range, population estimates, demographics, reproduction, and genetics.
Brickellia mosieri grows exclusively in pine rocklands on the Miami Rock Ridge in Miami-Dade County outside the boundaries of ENP. This area extends from the ENP boundary, near the park entrance road, northeast approximately 72 kilometers (km) (45 miles (mi)) to the ridge's end near North Miami. Habitat conditions more specific to this area are highlighted below. The pine rocklands are a unique ecosystem found on limestone substrates in three areas in Florida—the Miami Rock Ridge, in the Florida Keys, and in the Big Cypress Swamp. The pine rocklands differ to some degree between and within these areas with regard to substrate (e.g., amount of exposed limestone, type of soil), elevation, hydrology, and species composition (both plant and animal). The substrate, elevation, and hydrology of pine rocklands on the Miami Rock Ridge outside of ENP are discussed in detail in the proposed listing rule for B. mosieri and Linum carteri var. carteri (78 FR 61273; October 3, 2013), while the species composition of this area is discussed below.
Pine rockland is characterized by an open canopy of South Florida slash pine (Pinus elliottii var. densa). Subcanopy development is rare in well-maintained pine rocklands, with only occasional hardwoods, such as Lysiloma latisiliquum (wild tamarind) and Quercus virginiana (live oak) growing to tree size in Miami Rock Ridge pinelands (Snyder et al. 1990, p. 253). The shrub/understory layer is a diverse mix of Start Printed Page 52570species including both temperate and tropical shrubs and palms. Dominant plants in the shrub layer of pine rocklands vary based on elevation, substrate, and nearby associated natural communities. The pine rocklands where Brickellia mosieri occurs are characterized by an open shrub canopy of Serenoa repens (saw palmetto), Myrica cerifera (wax myrtle), Metopium toxiferum (poisonwood), and Sideroxylon salicifolium (willow bustic) as well as species with more restricted distribution within pine rocklands including Sideroxylon reclinatum ssp. austrofloridense (Everglades bully), Callicarpa americana (beauty berry), Dodonaea angustifolia (varnish leaf), and Ilex cassine (dahoon holly) (Snyder et al. 1990, p. 254; Bradley and Gann 1999, p. 12). The shrub layer in pinelands occurring in the northern end of the Miami Rock Ridge more closely resembles pine flatwoods as a result of the amount of sandy soils in this area, with species such as Lyonia fruticosa (staggerbush), Quercus minima (dwarf live oak), Quercus pumila (running oak), and Vaccinium myrsinites (shiny blueberry) becoming more common (Snyder et al. 1990, p. 255). The height and density of the shrub layer vary based on fire frequency, with understory plants growing taller and more dense as time since fire increases.
Pine rocklands in all three areas of Florida contain a richly diverse herbaceous layer, including a large number of rare and endemic species, such as Brickellia mosieri. The diversity of the herbaceous layer decreases as the density of the shrub layer increases (i.e., as understory openness decreases), and pine rockland on the mainland has a more diverse herbaceous layer, due to the presence of temperate species and some tropical species that do not occur in the Florida Keys (FNAI 2010, p. 63). The herbaceous layer can range from mostly continuous in areas with more soil development and little exposed limestone, to sparse where much of the limestone is at the surface. Most herbaceous species in pine rocklands are perennials (Snyder et al. 1990, p. 257). Common herbaceous associates of B. mosieri in the Miami Rock Ridge pine rocklands include Schizachyrium sanguineum (crimson bluestem), Schizachyrium gracile (wire bluestem), Symphyotrichum adnatum (scaleleaf aster), and Acalypha chamaedrifolia (bastard copperleaf) (Bradley and Gann 1999, p. 12). B. mosieri may also be found in close association with several other rare plants, including Chamaesyce deltoidea ssp. deltoidea (deltoid spurge), Chamaesyce deltoidea ssp. adhaerens (wedge sandmat), Chamaesyce deltoidea ssp. pinetorum (pineland sandmat), Galactia smallii (Small's milkpea), Polygala smallii (tiny polygala), and Argythamnia blodgettii (Blodgett's silverbush) (Bradley and Gann 1999, p. 12).
Pine rockland occurs in a mosaic with primarily two other natural community types—rockland hammock and marl prairie. Pine rockland grades into rockland hammock; pine rockland has an open pine canopy, and rockland hammock has a closed, hardwood canopy. Pine rockland is a fire-maintained ecosystem—a well-maintained pine rockland is a savanna-like forest, but, in the absence of fire, it will eventually succeed into rockland hammock. The functional relationship and response of pine rocklands and Brickellia mosieri to fire and other natural disturbances are discussed in detail in the proposed listing rule for B. mosieri and Linum carteri var. carteri (78 FR 61273; October 3, 2013).
Pine rockland on the Miami Rock Ridge can also occur within lower, seasonally flooded marl prairies, which differ from pine rockland in having no pines, an understory dominated by grasses and sedges, and a minimal cover of shrubs (FNAI 2010, p. 63). Where pine rockland occurs close to the ocean, it may be bordered by mangrove swamp or salt marsh and can receive flooding by extremely high tides (FNAI 2010, p. 63). Pine rocklands on the northern Miami Rock Ridge grade into scrub and mesic flatwoods vegetation where the three communities intermix in areas with deep sands and rock outcrops (Snyder et al. 1990, p. 257; Gann 2014, pers. comm.).
Brickellia mosieri is endemic to the pine rocklands of the Miami Rock Ridge in Miami-Dade County. It was historically known from central and southern Miami-Dade County from approximately Coconut Grove to Florida City, a range of approximately 45.0 km (28.0 mi), along the Miami Rock Ridge (based on data in Bradley and Gann 1999, p. 11, and Fairchild Tropical Botanic Garden Virtual Herbarium 2014, page numbers not applicable). However, Bradley and Gann (1999, p. 11) state that herbarium specimens have not been studied from the New York Botanical Garden, so the full extent of its historical range is unknown. Some available herbarium specimens and other records for this plant (Bradley and Gann 1999, p. 16; Wunderlin and Hansen 2008, page numbers not applicable) do not give precise or accurate location information.
Current Range, Population Estimates, and Status
Brickellia mosieri is currently distributed from central and southern Miami-Dade County from SW 120 St. (latitude ca. 25 degrees (°) 39.4 minutes (′)N) to Florida City (latitude ca. 25° 26.0′N) (Bradley and Gann 1999, p. 11), suggesting its historical range has contracted at least 13.6 km (8.5 mi), or more than 30 percent. A detailed account of B. mosieri occurrences and population status were provided in the proposed listing rule (78 FR 61273) published in the Federal Register on October 2, 2013.
Demographic, Reproductive Biology, and Population Genetics
Little research has been done into the demography, reproductive biology, or genetics of Brickellia mosieri. Field observations indicate that the species does not usually occur in great abundance—populations are typically sparse and contain a low density of plants even in well-maintained pine rockland habitat (Bradley and Gann 1999, p. 12). Reproduction is sexual (Bradley and Gann 1999, p. 12). While specific pollinators or dispersers are unknown, flower morphology suggests this species may be pollinated by butterflies, bees, or both (Koptur 2013, pers. comm.); wind is one likely dispersal vector (Gann 2013b, pers. comm.). Flowering takes place primarily in the fall (August-October) (Bradley and Gann 1999, p. 12). Off-season flowering is usually the result of fire, and B. mosieri will flower within 1 to 2 months following a fire, regardless of the time of year (Possley 2013 pers. comm.).
Linum carteri var. carteri
Please refer to the proposed listing rule (78 FR 61273; October 3, 2013) for a detailed discussion of Linum carteri var. carteri's taxonomy, suitable climate, habitat, historical and current range, population estimates, demographics, reproduction, and genetics. Below we provide an updated summary of information in the proposed rule, and new information based on peer review and public comment, related to the description of the plant.
Linum carteri var. carteri (Family: Linaceae) is an annual or short-lived perennial herb endemic to Miami-Dade County, where it grows in pine rocklands, particularly in disturbed pine rocklands (Bradley and Gann 1999, p. 70). Its stem is erect, 230-360 millimeters (mm) (9.0-14.2 inches (in)) tall, commonly branched near the base, Start Printed Page 52571and puberulent (covered with minute hairs). Its leaves are slender (18-26 mm (0.7-1.0 in) long and 0.8-1.2 mm (0.03-0.05 in) wide), entire, alternate, and closely overlap at the base of the plant. This variety has stipules (pair of appendages at the base of the petiole, which is the stalk by which a leaf is attached to a stem) with paired dark glands. Its inflorescence (cluster of flowers arranged on a branching stem) is an ascending or spreading cyme (usually flat-topped or convex flower cluster in which the main axis and each branch end in a flower that opens before the flowers below or to the side of it), with yellow petals that are broadly obovate (egg-shaped), 9-17 mm (0.35-0.67 in) long, and quickly deciduous. The fruit is straw-colored, ovoid, 4.1-4.6 mm (0.16-0.18 in) long, 3.4-3.7 mm (0.13-0.15 in) in diameter, and dehisces (opens spontaneously at defined places) into five two-seeded segments; seeds are narrowly ovoid-elliptic, 2.3-2.8 mm (0.09-0.11 in) long, 1.0-1.3 mm (0.04-0.05 in) wide. In habit and flower, the plant closely resembles Piriqueta cistoides ssp. caroliniana (pitted stripeseed) in the family Turneraceae (Bradley and Gann 1999, p. 70).
Summary of Factors Affecting the Species
Section 4 of the Act (16 U.S.C. 1533), and its implementing regulations at 50 CFR part 424, set forth the procedures for adding species to the Federal Lists of Endangered and Threatened Wildlife and Plants. Under section 4(a)(1) of the Act, we may determine a species to be endangered or threatened due to one or more of the following five factors: (A) The present or threatened destruction, modification, or curtailment of its habitat or range; (B) overutilization for commercial, recreational, scientific, or educational purposes; (C) disease or predation; (D) the inadequacy of existing regulatory mechanisms; or (E) other natural or manmade factors affecting its continued existence. Listing actions may be warranted based on any of the above threat factors, singly or in combination. Each of these factors as applied to these two plants is discussed below or in the proposed listing rule for Brickellia mosieri and Linum carteri var. carteri (78 FR 61273; October 3, 2013).
A. The Present or Threatened Destruction, Modification, or Curtailment of Its Habitat or Range
Brickellia mosieri and Linum carteri var. carteri have experienced substantial destruction, modification, and curtailment of their habitat and range (see Status Assessment, in the proposed listing rule for B. mosieri and L. c. var. carteri (78 FR 61273; October 3, 2013) and revised information above). Specific threats to these plants included in this factor include habitat loss, fragmentation, and modification caused by development (i.e., conversion to both urban and agricultural land uses) and inadequate fire management. Human population growth and development and habitat fragmentation and their specific effects on these plants are discussed in the proposed listing rule for B. mosieri and L. c. var. carteri (78 FR 61273; October 3, 2013), while fire management is summarized below.
One of the primary threats to both of these plants is habitat modification and degradation through inadequate fire management, which includes both the lack of prescribed fire and suppression of natural fires. Where the term “fire-suppressed” is used below and in the proposed rule, it describes degraded pine rockland conditions resulting from a lack of adequate fire (natural or prescribed) in the landscape. The effects of fire suppression on pine rocklands, and fire-adapted species such as Brickellia mosieri and Linum carteri var. carteri, are discussed in detail in the proposed listing rule for B. mosieri and L. c. var. carteri (78 FR 61273; October 3, 2013).
Brickellia mosieri—All occurrences of Brickellia mosieri are affected by some degree of inadequate fire management, with the primary threat being shading by hardwoods (Bradley and Gann 1999, p. 15; Bradley and Gann 2005, page numbers not applicable). While management of some County conservation lands (e.g., those in Richmond Pinelands complex and Navy Wells Pineland Preserve) includes regular burning, other such lands can be severely fire-suppressed. Even in areas under active management, some portions are typically fire-suppressed, thereby threatening populations of this species.
Linum carteri var. carteri—The status of Linum carteri var. carteri populations in relation to fire suppression are described in the proposed listing rule for Brickellia mosieri and L. c. var. carteri (78 FR 61273; October 3, 2013).
Implementation of a prescribed fire program in Miami-Dade County has been hampered by a shortage of resources, and by logistical difficulties and public concern related to burning next to residential areas. Many homes have been built in a mosaic of pine rockland, so the use of prescribed fire in many places has become complicated because of potential danger to structures and smoke generated from the burns. Nonprofit organizations, such as the Institute for Regional Conservation (IRC) have similar difficulties in conducting prescribed burns due to difficulties with permitting and obtaining the necessary permissions as well as hazard insurance limitations (Gann 2013a, pers. comm.). Few private landowners have the means and/or desire to implement prescribed fire on their property, and doing so in a fragmented urban environment is logistically difficult and may be costly. One of the few privately owned pine rocklands that is successfully managed with prescribed burning is Pine Ridge Sanctuary, located in a more agricultural (less urban) matrix in the southwestern portion of Brickellia mosieri's current range; it was last burned in November 2010 (Glancy 2013, pers. comm.).
Conservation Efforts To Reduce the Present or Threatened Destruction, Modification, or Curtailment of Habitat or Range
These are discussed in detail in the proposed listing rule for Brickellia mosieri and Linum carteri var. carteri (78 FR 61273; October 3, 2013).
B. Overutilization for Commercial, Recreational, Scientific, or Educational Purposes
Factor B is discussed in detail in the proposed listing rule for Brickellia mosieri and Linum carteri var. carteri (78 FR 61273; October 3, 2013).
C. Disease or Predation
No diseases or incidences of predation have been reported for Brickellia mosieri and Linum carteri var. carteri.
D. The Inadequacy of Existing Regulatory Mechanisms
State and local regulations, and fee title properties, are discussed in detail in the proposed listing rule for Brickellia mosieri and Linum carteri var. carteri (78 FR 61273; October 3, 2013), while Federal regulations are discussed below.
If these plants were not listed, they would have no Federal regulatory protection in their known occupied and suitable habitat. Neither taxon occurs on National Wildlife Refuge or National Park land. Brickellia mosieri is known to occur within habitat patches (where patch boundaries are based on contiguous pine rockland habitat, irrespective of land ownership) that include Federal lands within the Richmond Pinelands Complex, including lands owned by the USCG Start Printed Page 52572and NOAA. The only known Federal occurrence of Linum carteri var. carteri is on the U.S. Department of Agriculture's Subtropical Horticultural Research Station (Chapman Field). There are no Federal protections for candidate species on these properties. These plants primarily occur on State- or County-owned and private land (Tables 1 and 2 of the proposed rule), and development of these areas would likely require no Federal permit or other authorization. Therefore, projects that affect them would usually not be analyzed under the National Environmental Policy Act (NEPA) (42 U.S.C. 4321 et seq.).
E. Other Natural or Manmade Factors Affecting Its Continued Existence
Brickellia mosieri and Linum carteri var. carteri are both threatened by other natural or manmade factors that affect each taxon to varying degrees. Specific threats to these plants included in this factor consist of the spread of nonnative invasive plants, potentially incompatible management practices (such as mowing and herbicide use), direct impacts to plants from recreation and other human activities, small population size and isolation, climate change, and the related risks from environmental stochasticity (extreme weather) on these small populations. With the exception of nonnative plants and recreation, which are discussed below, the rest of these threats and their specific effect on these plants are discussed in detail in the proposed listing rule for B. mosieri and L. c. var. carteri (78 FR 61273; October 3, 2013).
Nonnative Plant Species
Nonnative plants have significantly affected pine rocklands, and threaten all occurrences of Brickellia mosieri and Linum carteri var. carteri to some degree (Bradley and Gann 1999, pp. 15, 72; Bradley and Gann 2005, page numbers not applicable; Bradley 2007, pers. comm.; Bradley and van der Heiden 2013, pp. 12-16). As a result of human activities, at least 277 taxa of nonnative plants have invaded pine rocklands throughout south Florida (Service 1999, p. 3-175). Neyraudia reynaudiana (Burma reed) and Schinus terebinthifolius (Brazilian pepper) threaten both plants (Bradley and Gann 1999, pp. 13, 72). S. terebinthifolius, a nonnative tree, is the most widespread and one of the most invasive species. It forms dense thickets of tangled, woody stems that completely shade out and displace native vegetation (Loflin 1991, p. 19; Langeland and Craddock Burks 1998, p. 54). Acacia auriculiformis (earleaf acacia), Melinis repens (natal grass), Lantana camara (shrub verbena), and Albizia lebbeck (tongue tree) are some of the other nonnative species in pine rocklands.
Nonnative invasive plants compete with native plants for space, light, water, and nutrients, and make habitat conditions unsuitable for both Brickellia mosieri and Linum carteri var. carteri, which respond positively to open conditions. They also affect the characteristics of a fire when it does occur. Historically, pine rocklands had an open, low understory where natural fires remained patchy with low temperature intensity, thus sparing many native plants such as B. mosieri and L. c. var. carteri. Dense infestations of Neyraudia reynaudiana and Schinus terebinthifolius cause higher fire temperatures and longer burning periods. With the presence of invasive nonnative species, it is uncertain how fire, even under a managed situation, will affect these plants. Bradley and Gann (1999, pp. 13, 71-72) indicated that the control of nonnative plants is one of the most important conservation actions for these plants and a critical part of habitat maintenance.
Management of nonnative invasive plants in pine rocklands in Miami-Dade County is further complicated because the vast majority of pine rocklands are small, fragmented areas bordered by urban development. Areas near managed pine rockland that contain nonnative species can act as a seed source of nonnatives allowing them to continue to invade the surrounding pine rockland (Bradley and Gann 1999, p. 13).
Recreation and Other Human Activities
Linum carteri var. carteri' s occurrence in disturbed, open areas such as firebreaks and road rights-of-way also makes it much more susceptible than Brickellia mosieri to recreational and other human activities. These activities may inadvertently impact some populations of L. c. var. carteri. In the past, mountain biking has been identified as a threat at R. Hardy Matheson Preserve (Bradley and Gann 1999, pp. 71, 74; Bradley 2007, pers. comm.). This threat was mitigated by the placement of protective fencing, however, since mountain bikers have been fenced out, habitat succession has increased and resulted in less suitable conditions for L. c. var. carteri (Possley 2013, pers. comm.). More recently, a colony of L. c. var. carteri at Camp Owaissa Bauer Addition has been impacted by “yard sales” and car parking along Krome Avenue (Bradley and van der Heiden 2013, p. 13). While these impacts are usually some distance from the plants, they sometimes encroach on the edge of the natural area and have the potential to trample the plants. This plant occurs in similar habitat on Rockdale Pineland, where it is found along the edges of the abandoned Florida East Coast Railway tracks, adjacent to pine rockland habitat (Bradley and van der Heiden 2013, p. 16). Here, plants have also been trampled from parking vehicles and machinery along the edges of the railroad right-of-way (Bradley and van der Heiden 2013, p. 16). While these activities have affected individual plants in some populations, they are not likely to have caused significant population declines in the taxon.
Conservation Efforts To Reduce Other Natural or Manmade Factors Affecting Continued Existence
An IRC program included reintroduction of both Brickellia mosieri and Linum carteri var. carteri in an effort to establish new occurrences of these plants and increase population sizes. To date, B. mosieri has been reintroduced to at least one private site, although the status of these plants is currently unknown (Gann 2013b, pers. comm.).
Ex-situ conservation by Fairchild Tropical Botanic Garden consists of seed collection of pine rockland plants, including Brickellia mosieri and Linum carteri var. carteri, to learn about their germination, storage, and cultivation requirements to help safeguard these plants from extinction. This program is discussed in detail in the proposed listing rule for Brickellia mosieri and Linum carteri var. carteri (78 FR 61273; October 3, 2013).
Summary of Biological Status and Threats
Only small and fragmented occurrences of these two plants remain. The current ranges of Brickellia mosieri and Linum carteri var. carteri span such a small geographic area—a narrow band no more than 4.0 km (2.5 mi) in width, and approximately 30.1 km (18.7 mi) and 26.9 km (16.7 mi) in length, respectively, along the Miami Rock Ridge—that all populations could be affected by a single event (e.g., hurricane). Four of the seven remaining populations of L. c. var. carteri have fewer than 20 individual plants. B. mosieri populations occur in higher numbers, but are still not considered sizable. L. c. var. carteri shows great differences in plant numbers from year to year, probably because individuals typically live 1-2 years and grow from seed. This trait makes them more vulnerable than perennials to changes in Start Printed Page 52573environment. Viable plant populations for small, short-lived herbs may consist of tens of thousands of plants (Menges 1991, p. 48; Lande 1995, p. 789). Although robust population viability analyses (including minimum viable population calculations) have not been conducted for these plants, indications are that most existing populations for both plants are at best marginal.
We have determined that the threats to both Brickellia mosieri and Linum carteri var. carteri consist primarily of habitat loss and modification through urban and agricultural development, lack of adequate fire management, proliferation of nonnative invasive plants, and sea level rise. Threats described under Factor A—habitat loss, fragmentation, and degradation resulting from development and inadequate fire management, and Factor E—competition from nonnative invasive plants, are believed to be the primary drivers in the historical and recent declines of B. mosieri and L. c. var. carteri. L. c. var. carteri has also been threatened by anthropogenic disturbances which threaten populations in disturbed habitats, such as firebreaks and road rights-of-way, and both plants are suspected to be negatively affected by threats related to small, isolated populations (Factor E). All of these threats are ongoing and expected to continue to impact populations of these plants in the future. Current local, State, and Federal regulatory mechanisms (Factor D) are inadequate to protect these plants from taking and habitat loss. Despite these existing regulatory mechanisms, B. mosieri and L. c. var. carteri continue to decline.
Other factors that are likely to threaten Brickellia mosieri and Linum carteri var. carteri in the future include climate change (including sea level rise) and extreme weather events (hurricanes, frost events). Effects of these could be catastrophic on isolated, small populations of both plants (Factor E). The narrow distribution of their populations makes them more susceptible to extirpation from a single catastrophic event. This level of isolation makes natural recolonization of extirpated populations virtually impossible without human intervention.
We have carefully assessed the best scientific and commercial information available regarding the past, present, and future threats to Brickellia mosieri and Linum carteri var. carteri. As described in detail above and in the proposed listing rule (78 FR 61273; October 3, 2013), both plants are currently at risk throughout all of their respective ranges due to the immediacy and severity of threats from habitat destruction and modification (Factor A) and other natural or manmade factors affecting their continued existence (Factor E), and existing regulatory mechanisms are inadequate to reduce these threats (Factor D). Although actions are ongoing to alleviate some threats, no populations appear to be free of major threats. As a result, impacts from increasing threats, singly or in combination, are likely to result in the extinction of these plants.
Numerous threats are occurring now and are likely to continue in the foreseeable future, at a high intensity, and across the entire range of Brickellia mosieri; therefore, we have determined the species is in danger of extinction throughout its range. The threats are currently active, and will continue to affect the populations of B. mosieri into the foreseeable future, and these threats will individually and collectively contribute to the species' local extirpation and potential extinction. Because these threats are placing the species in danger of extinction now and not only at some point in the foreseeable future, we find that this species meets the definition of an endangered species, rather than a threatened species. Therefore, we have determined that B. mosieri meets the definition of endangered in accordance with sections 3(6) and 4(a)(1) of the Act.
Linum carteri var. carteri
Numerous threats are occurring now and are likely to continue in the foreseeable future, at a high intensity, and across the entire range of Linum carteri var. carteri; therefore, we have determined the taxon is in danger of extinction throughout its range. The threats are currently active, and will continue to affect the populations of L. c. var. carteri into the foreseeable future, and these threats will individually and collectively contribute to the plant's local extirpation and potential extinction. Because these threats are placing the taxon in danger of extinction now and not only at some point in the foreseeable future, we find this taxon meets the definition of an endangered species rather than a threatened species. Therefore, we have determined that L. c. var. carteri meets the definition of endangered in accordance with sections 3(6) and 4(a)(1) of the Act.
The Act defines an endangered species as any species that is “in danger of extinction throughout all or a significant portion of its range” and a threatened species as any species “that is likely to become endangered throughout all or a significant portion of its range within the foreseeable future.” We find that threatened species status is not appropriate for these plants because of contracted range, because the threats are occurring rangewide and are not localized, and because the threats are ongoing and expected to continue into the future.
Under the Act and our implementing regulations, a species may warrant listing if it is endangered or threatened throughout all or a significant portion of its range. The threats to the survival of these plants occur throughout the plants' respective ranges and are not restricted to any particular significant portion of those ranges. Accordingly, our assessment and proposed determination applies to the plants throughout their entire ranges.
Available Conservation Measures
Conservation measures provided to species listed as endangered or threatened under the Act include recognition, recovery actions, requirements for Federal protection, and prohibitions against certain practices. Recognition through listing results in public awareness and conservation by Federal, State, Tribal, and local agencies, private organizations, and individuals. The Act encourages cooperation with the States and requires that recovery actions be carried out for all listed species. The protection required by Federal agencies and the prohibitions against certain activities are discussed, in part, below.
The primary purpose of the Act is the conservation of endangered and threatened species and the ecosystems upon which they depend. The ultimate goal of such conservation efforts is the recovery of these listed species, so that they no longer need the protective measures of the Act. Subsection 4(f) of the Act requires the Service to develop and implement recovery plans for the conservation of endangered and threatened species. The recovery planning process involves the identification of actions that are necessary to halt or reverse the species' decline by addressing the threats to its survival and recovery. The goal of this process is to restore listed species to a point where they are secure, self-sustaining, and functioning components of their ecosystems.
Recovery planning includes the development of a recovery outline shortly after a species is listed and preparation of a draft and final recovery plan. The recovery outline guides the immediate implementation of urgent Start Printed Page 52574recovery actions and describes the process to be used to develop a recovery plan. Revisions of the plan may be done to address continuing or new threats to the species, as new substantive information becomes available. The recovery plan identifies site-specific management actions that set a trigger for review of the five factors that control whether a species remains endangered or may be downlisted or delisted, and methods for monitoring recovery progress. Recovery plans also establish a framework for agencies to coordinate their recovery efforts and provide estimates of the cost of implementing recovery tasks. Recovery teams (composed of species experts, Federal and State agencies, nongovernmental organizations, and stakeholders) are often established to develop recovery plans. When completed, the recovery outline, draft recovery plan, and the final recovery plan will be available on our Web site (http://www.fws.gov/endangered), or from our South Florida Ecological Services Field Office (see FOR FURTHER INFORMATION CONTACT).
Implementation of recovery actions generally requires the participation of a broad range of partners, including other Federal agencies, States, Tribes, nongovernmental organizations, businesses, and private landowners. Examples of recovery actions include habitat restoration (e.g., restoration of native vegetation), research, captive propagation and reintroduction, and outreach and education. The recovery of many listed species cannot be accomplished solely on Federal lands because their range may occur primarily or solely on non-Federal lands. To achieve recovery of these species requires cooperative conservation efforts on private, State, and Tribal lands.
Following publication of this final listing rule, funding for recovery actions will be available from a variety of sources, including Federal budgets, State programs, and cost share grants for non-Federal landowners, the academic community, and nongovernmental organizations. In addition, pursuant to section 6 of the Act, the State of Florida would be eligible for Federal funds to implement management actions that promote the protection or recovery of Brickellia mosieri and Linum carteri var. carteri. Information on our grant programs that are available to aid species recovery can be found at: http://www.fws.gov/grants.
Please let us know if you are interested in participating in recovery efforts for Brickellia mosieri and Linum carteri var. carteri. Additionally, we invite you to submit any new information on these plants whenever it becomes available and any information you may have for recovery planning purposes (see FOR FURTHER INFORMATION CONTACT).
Section 7(a) of the Act requires Federal agencies to evaluate their actions with respect to any species that is proposed or listed as an endangered or threatened species and with respect to its critical habitat, if any is designated. Regulations implementing this interagency cooperation provision of the Act are codified at 50 CFR part 402. Section 7(a)(4) of the Act requires Federal agencies to confer with the Service on any action that is likely to jeopardize the continued existence of a species proposed for listing or result in destruction or adverse modification of proposed critical habitat. If a species is listed subsequently, section 7(a)(2) of the Act requires Federal agencies to ensure that activities they authorize, fund, or carry out are not likely to jeopardize the continued existence of the species or destroy or adversely modify its critical habitat. If a Federal action may affect a listed species or its critical habitat, the responsible Federal agency must enter into consultation with the Service.
Federal agency actions within the species' habitat that may require conference or consultation or both as described in the preceding paragraph include, but are not limited to, management and any other landscape-altering activities on Federal lands administered by the Department of Defense, Homeland Security/U.S. Coast Guard, U.S. Prisons Bureau, National Oceanic and Atmospheric Administration, National Park Service, U.S. Fish and Wildlife Service, and U.S. Department of Agriculture; the issuance of Federal permits under section 404 of the Clean Water Act (33 U.S.C. 1251 et seq.) by the U.S. Army Corps of Engineers; construction and management of gas pipeline and power line rights-of-way by the Federal Energy Regulatory Commission; construction and maintenance of roads or highways by the Federal Highway Administration; and implementation of the National Flood Insurance Program and disaster relief efforts conducted by the Federal Emergency Management Agency.
The Act and its implementing regulations set forth a series of general prohibitions and exceptions that apply to endangered plants. All prohibitions of section 9(a)(2) of the Act, implemented by 50 CFR 17.61, apply. These prohibitions, in part, make it illegal for any person subject to the jurisdiction of the United States to import or export, transport in interstate or foreign commerce in the course of a commercial activity, sell or offer for sale in interstate or foreign commerce, or remove and reduce the species to possession from areas under Federal jurisdiction. In addition, for plants listed as an endangered species, the Act prohibits the malicious damage or destruction on areas under Federal jurisdiction and the removal, cutting, digging up, or damaging or destroying of such plants in knowing violation of any State law or regulation, including State criminal trespass law. Exceptions to these prohibitions are outlined in 50 CFR 17.62.
Preservation of native flora of Florida (Florida Statutes 581.185) sections (3)(a) and (b) provide limited protection to species listed in the State of Florida Regulated Plant Index including Brickellia mosieri and Linum carteri var. carteri, as described under Factor D, The Inadequacy of Existing Regulatory Mechanisms. Federal listing increases protection for these plants by making violations of section 3 of the Florida Statute punishable as a Federal offense under section 9 of the Act. This statutory relationship provides increased protection from unauthorized collecting and vandalism for the plants on State and private lands, where they might not otherwise be protected by the Act, and increases the severity of the penalty for unauthorized collection, vandalism, or trade in these plants.
We may issue permits to carry out otherwise prohibited activities involving endangered and threatened plant species under certain circumstances. Regulations governing permits are codified at 50 CFR 17.62 for endangered plants, and at 50 CFR 17.72 for threatened plants. With regard to endangered plants, a permit must be issued for activities undertaken for scientific purposes or to enhance the propagation or survival of the species.
It is our policy, as published in the Federal Register on July 1, 1994 (59 FR 34272), to identify to the maximum extent practicable at the time a species is listed, those activities that would or would not constitute a violation of section 9 of the Act. The intent of this policy is to increase public awareness of the effect of a listing on proposed and ongoing activities within the range of listed species. The following activities could potentially result in a violation of section 9 of the Act; this list is not comprehensive:
(1) Import Brickellia mosieri or Linum carteri var. carteri into, or export these plants from, the United States.
(2) Remove and reduce to possession Brickellia mosieri or Linum carteri var. carteri from areas under Federal jurisdiction; maliciously damage or Start Printed Page 52575destroy these plants on any such area; or remove, cut, dig up, or damage or destroy these plants on any other area in knowing violation of any law or regulation of any State or in the course of any violation of a State criminal trespass law.
(3) Deliver, receive, carry, transport, or ship in interstate or foreign commerce, by any means whatsoever and in the course of a commercial activity, Brickellia mosieri or Linum carteri var. carteri.
(4) Sell or offer for sale in interstate or foreign commerce Brickellia mosieri or Linum carteri var. carteri.
(5) Introduce any nonnative wildlife or plant species to the State of Florida that compete with or prey upon Brickellia mosieri or Linum carteri var. carteri.
(6) Release any unauthorized biological control agents that attack any life stage of Brickellia mosieri or Linum carteri var. carteri.
(7) Manipulate or modify the habitat of Brickellia mosieri or Linum carteri var. carteri on Federal lands without authorization.
Questions regarding whether specific activities would constitute a violation of section 9 of the Act should be directed to the South Florida Ecological Services Field Office (see FOR FURTHER INFORMATION CONTACT).
National Environmental Policy Act (42 U.S.C. 4321 et seq.)
We have determined that environmental assessments and environmental impact statements, as defined under the authority of the National Environmental Policy Act need not be prepared in connection with listing a species as an endangered or threatened species under the Endangered Species Act. We published a notice outlining our reasons for this determination in the Federal Register on October 25, 1983 (48 FR 49244).
Government-to-Government Relationship With Tribes
In accordance with the President's memorandum of April 29, 1994 (Government-to-Government Relations with Native American Tribal Governments; 59 FR 22951), Executive Order 13175 (Consultation and Coordination With Indian Tribal Governments), and the Department of the Interior's manual at 512 DM 2, we readily acknowledge our responsibility to communicate meaningfully with recognized Federal Tribes on a government-to-government basis. In accordance with Secretarial Order 3206 of June 5, 1997 (American Indian Tribal Rights, Federal-Tribal Trust Responsibilities, and the Endangered Species Act), we readily acknowledge our responsibilities to work directly with tribes in developing programs for healthy ecosystems, to acknowledge that tribal lands are not subject to the same controls as Federal public lands, to remain sensitive to Indian culture, and to make information available to tribes. No tribal lands are impacted by this listing.
