Fish and Wildlife Service, Interior.
Notice of 12-month petition finding.
We, the Fish and Wildlife Service (Service), announce a 12-month finding on a petition to list the plant Agave eggersiana (no common name) as endangered under the Endangered Species Act of 1973, as amended (Act). After review of all available scientific and commercial information, we find that listing A. eggersiana is warranted. Currently, however, listing A. eggersiana is precluded by higher priority actions to amend the Lists of Endangered and Threatened Wildlife and Plants. Upon publication of this 12-month petition finding, we will add A. eggersiana to our candidate species list. We will develop a proposed rule to list A. eggersiana as our priorities allow. We will make any determination on critical habitat during development of the proposed listing rule. In any interim period the status of the candidate taxon will be addressed through our annual Candidate Notice of Review (CNOR).
The finding announced in this document was made on September 22, 2010.
This finding is available on the Internet at http://www.regulations.gov at Docket Number [FWS-R4-ES-2010-0051]. Supporting documentation we used in preparing this finding is available for public inspection, by appointment, during normal business hours at the U.S. Fish and Wildlife Service, Caribbean Ecological Services Field Office, Road 301, Km. 5.1, Boquero´n, Puerto Rico 00622.

Section 4(b)(3)(A) of the Act (16 U.S.C. 1531 et seq.) requires that, for any petition to revise the Federal Lists of Threatened and Endangered Wildlife and Plants that contains substantial scientific or commercial information that listing a species may be warranted, we make a finding within 12 months of the date of receipt of the petition. In this finding, we determine whether the petitioned action is: (a) Not warranted, (b) warranted, or (c) warranted, but immediate proposal of a regulation implementing the petitioned action is precluded by other pending proposals to determine whether species are threatened or endangered, and expeditious progress is being made to add or remove qualified species from the Federal Lists of Endangered and Threatened Wildlife and Plants. Section 4(b)(3)(C) of the Act requires that we treat a petition for which the requested action is found to be warranted but precluded as though resubmitted on the date of such finding, that is, requiring a subsequent finding to be made within 12 months. We must publish these 12-month findings in the Federal Register.Start Printed Page 57721
Previous Federal Actions
We identified Agave eggersiana as a category 2 candidate species in the Notice of Review published in the Federal Register on September 30, 1993 (58 FR 51144) and subsequent publication. A category 2 species was one for which the Service had information that proposing as endangered or threatened may be appropriate but for which sufficient information was not currently available to support a proposed rule. Designation of category 2 species was discontinued in the February 28, 1996, Notice of Review (61 FR 7596). This notice redefined candidates to include only species for which we have information needed to propose them for listing, and as a result, Agave eggersiana was removed from the Candidate species list.
On November 21, 1996, we received a petition from the U.S. Virgin Islands Department of Planning and Natural Resources (DPNR) requesting that we list Agave eggersiana and Solanum conocarpum as endangered. On November 16, 1998, we published in the Federal Register (63 FR 63659) our finding that the petition to list A. eggersiana and S. conocarpum presented substantial information indicating that the requested action may be warranted and initiated a status review on these two plants. On September 1, 2004, the Center for Biological Diversity filed a lawsuit against the Department of the Interior and the U.S. Fish and Wildlife Service (Service) alleging that the Service failed to publish a 12-month finding for A. eggersiana and S. conocarpum (Center for Biological Diversity v. Norton, Civil Action No. 1:04-CV-2553 CAP). In a stipulated settlement agreement resolving that case, signed April 27, 2005, we agreed to submit our 12-month finding for A. eggersiana and S. conocarpum to the Federal Register by February 28, 2006. On March 7, 2006, we published our 12-month finding (71 FR 11367) that listing of A. eggersiana and S. conocarpum was not warranted. On September 9, 2008, the Center for Biological Diversity filed a complaint challenging our 12-month finding (Center for Biological Diversity v. Hamilton, Case No. 1:08-cv-02830 -CAP). In a settlement agreement approved by the Court on August 21, 2009, the Service agreed to submit to the Federal Register a new 12-month finding for A. eggersiana by September 17, 2010. This notice constitutes the 12-month finding on the 1996 petition to list A. eggersiana as endangered.
Taxonomy and Species Description
Agave eggersiana is a flowering plant of the family Agavaceae (century plant family) endemic to the island of St. Croix in the U.S. Virgin Islands. A. eggersiana was originally described in 1913 by Trelease from material collected on St. Croix, and is distinguished from other members of the Agavaceae family by its acaulescent (without an evident leafy stem), non-suckering growth habit (vegetative reproduction that does not form offshoots around its base), and fleshy, nearly straight leaves with small marginal prickles (1.00 millimeter (mm); 0.04 inches (in) long) that are nearly straight (Britton and Wilson 1923, p. 156; Proctor and Acevedo-Rodri´guez 2005, p. 118). Its flowers are deep yellow, 5 to 6 centimeters (cm) (1.95 to 2.34 in) long. After flowering, the panicles (inflorescence) produce numerous small vegetative bulbs (bulbils), from which the species can be propagated (Proctor and Acevedo-Rodri´guez 2005, p. 118). Avave eggersiana is not known to produce fruit. Furthermore, based on observations of cultivated plants, Agave eggersiana requires at least 10 to 15 years to develop as a mature individual and to produce an inflorescence (David Hamada, St. George Botanical Garden, 2010, pers. comm.). Avave eggersiana like other Agave species are monocarpic, meaning the plant dies after producing the spike or inflorescence.
Habitat and Distribution
Britton and Wilson (1923, p. 156) reported the species from hillsides and plains in the eastern dry districts of St. Croix but did not provide population estimates. In addition, Agave eggersiana is cultivated on St. Croix and St. Thomas for ornament (Trelease 1913, p. 28; Britton and Wilson 1923, p. 156; Proctor and Acevedo-Rodri´guez 2005, p. 118). Information provided in the petition (Kojis and Boulon, DPNR, 1996, pers. comm.) specified that the species was last observed growing in the wild around 1984 to 1986 on St. Croix. In 2003, DPNR stated that the species is believed to be extinct (Plaskett 2003, pers. comm.; Dalmida-Smith 2010, pers. comm.). Proctor and Acevedo-Rodri´guez (2005, p. 118) provided a general description of the species and they state that the species “now appears to be extinct in the wild.” However, no citations or survey information were provided to support this statement. Subsequently, in 2010, DPNR provided information based on field visits and reported the existence of several populations in St. Croix (Dalmida-Smith 2010, pers. comm.).
Historically, Agave eggersiana was reported from the north coast in Christiansted, St. Croix and along the south coast of the island. The current distribution and rarity of the species do not represent the historical range. Historically, sugar cane was the main crop on the island and dominated the economy for nearly 200 years (Shaw, 1933, p. 414). Apparently, the former land use of the areas used for sugar cane cultivation resulted in degradation of the species' habitat and nearly extirpated the species from the wild. Sugarcane is no longer cultivated on the island and the majority of the areas formerly used for sugarcane plantations are currently grasslands and early secondary forests dominated by the exotic tree Leucaena leucocephala (tantan).
In 2010, the Division of Fish and Wildlife of the DPNR (Dalmida-Smith 2010, pers. comm.) conducted a local status review to determine the extent of the populations of Agave eggersiana in St. Croix. They reported five sites where the species was found; however, it is uncertain if these populations are natural populations (individuals that come from wild populations) or if the populations consist of individuals that escaped from landscaping. The five reported sites are: (1) Manchineel/ Ha'penny Beach (Southern St. Croix) with an estimated 30 individuals, which is approximately half the number of individuals that they encountered 2 years before; (2) West side of Vagthus point (Southern St. Croix ) with a single individual; (3) Gallows Bay (Northern St. Croix) with several plants but no approximate number was mentioned; (4) Protestant Cay (Northern St. Croix) with an estimated 30 individuals, including a number of young plants; and (5) Ruth Island (Southern St. Croix) with a single individual that was introduced to the cay many years ago. However, the exact year of this introduction is unknown.
In February 2010, Service biologists conducted surveys of Agave eggersiana on St. Croix. In their 2010 surveys, Service biologists visited seven of the ten currently known populations (Table 1). They did not survey the two areas where a single individual has been reported (Ruth Island and West Vagthus point) or Buck Island Reef National Monument, where individuals have been planted and recent survey information exists. Based on their characteristics (growing mixed with native vegetation, evidence of natural recruitment and the presence of Start Printed Page 57722different size classes), these surveys indicate that the species currently occurs in six areas that appear to be remnants of wild populations. Four localities (Buck Island Reef National Monument, Salt River Bay, Ruth Island, and Lagoon Picnic Area) contain individuals that were planted in recent years.

The eight localities containing multiple Agave eggersiana plants are described as follows:
(1) Gallows Bay (private property) has several individuals that are considered by local experts as a remnant of a natural population (David Hamada 2010, pers. comm.). Historical documents and illustrations show that Agave eggersiana was common on the landscape of Gallows Bay (David Hamada 2010, pers. comm.).
(2) Protestant Cay (owned by the government but leased to a private party), has an estimated population of 51 adult individuals of different sizes and about 60 bulbils.
(3) Ha'penny Beach (private property), has an estimated population of 25 individuals of different size classes; one of the plants was found flowering during the site visit conducted by the Service in 2010.
(4) Great Pond (managed by the Department of Housing, Parks and Recreation) has a healthy population of A. eggersiana with different size plants and evidence of recent flowering events. This population is located near Great Pond, an area where it was suspected that descendants from wild plants may have existed (Plaskett 2003, pers. comm.).
(5) South Shore (private property), has a population of about 100 adult individuals and about 150 bulbils, all growing on small terraces at a rocky cliff. This population is actively flowering and it was noted that some of the bulbils are reaching the sea, suggesting a possible dispersal mechanism for the species.
(6) Salt River Bay National Historic Park and Ecological Preserve (SARI) (managed by the National Park Service (NPS)) has six individual plants. In 2007, personnel from the NPS planted these individuals at Salt River as part of the landscape with the idea of establishing a population at the site and for outreach purposes. At the time of the survey, five of these plants were producing spikes and were expected to produce bulbils within the following months (Monsegur and Vargas, USFWS, 2010, unpublished data). Based on information provided by personnel from NPS, additional propagation efforts with the species are planned in the near future (Lundgreen 2010, pers. comm.).
(7) Buck Island Reef National Monument (managed by the NPS) has an estimated population of five individuals. In 2007, personnel from NPS planted these five individuals on the island, but at present time there is no information regarding the breeding condition of these plants (Lundgreen 2010, pers. comm.).
(8) Lagoon Picnic Area (a public beach area that seems to be under a reforestation effort funded by the Antilitter and Beautification Commission) harbors about 177 plants as part of the landscape. The size of the individuals in this area ranges from small planted bulbils to a few adult individuals ready to flower. Based on the information gathered and observations, about 450 adult individuals and 260 bulbils are currently known in 10 localities, including 6 populations that are considered wild, 3 introduced populations for conservation and public education, and 1 landscape population (Table 1). In addition to these localities, Monsegur and Vargas (2010, personal observation) documented the species presence in private gardens scattered throughout the island. We estimate about 90 adult individuals are present in these private gardens.
At the present time, information on ecology, phenology, and genetics for Agave eggersiana is lacking. Samples of A. eggersiana from individuals in the Gallows Bay area have been collected for genetics analysis, but results were not available prior to making this finding (Ray 2010, pers. comm.). Start Printed Page 57723 Current evidence suggests that the wild and cultivated populations have minimum genetic variation. Therefore, all A. eggersiana plants (cultivated and wild) are included as part of the listable entity in this finding; however, we have focused our assessment of threats to the wild populations. Although data suggest that cultivated individuals could be used as genetic stock to aid in the long-term survival of this species, most cultivated populations are groomed to prevent recruitment and thus offer minimal conservation contribution. We do not feel that cultivated individuals propagated for private or commercial uses aid in the conservation or the recovery of the species in the wild.
Summary of Information Pertaining to the Five Factors
Section 4 of the Act (16 U.S.C. 1533), and implementing regulations (50 CFR 424), set forth procedures for adding species to the Federal Lists of Endangered and Threatened Wildlife and Plants. Under section 4(a)(1) of the Act, a species may be determined to be endangered or threatened based on any 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. In making this finding, information pertaining to Agave eggersiana, in relation to the five factors provided in section 4(a)(1) of the Act is discussed below.
In considering what factors might constitute threats to a species, we must look beyond the exposure of the species to a factor to evaluate whether the species may respond to the factor in a way that causes actual impacts to the species. If there is exposure to a factor and the species responds negatively, the factor may be a threat and we attempt to determine how significant a threat it is. The threat is significant if it drives, or contributes to, the risk of extinction of the species such that the species warrants listing as endangered or threatened as those terms are defined in the Act.
Factor A: The Present or Threatened Destruction, Modification, or Curtailment of the Species' Habitat or Range
Of the currently known populations, only three areas are managed for conservation (Ruth Island, Salt River Bay, and Buck Island National Monument), the remaining populations occur within privately owned lands currently threatened by development or areas already developed and managed as tourism and residential projects. Based on information reported by the University of the Virgin Islands' Conservation Data Center (http://cdc.uvi.edu), at least three of the populations (Protestant Cay, Gallows Bay, and Ha'penny Beach) lie within areas identified by the DPNR as high-density land use areas, which have a higher susceptibility to development in the near future. Furthermore, Weiss (2010, pers. comm.) identified two proposed development projects within suitable habitat for the species (C&R Robin, LLC and Seven Hills Beach Resort and Casino). Based on the field assessment conducted by Service biologists, the coastal areas that harbor suitable habitat for the species are currently subject to urban and tourist development (Monsegur and Vargas 2010, personal observation).
The population at Protestant Cay seems to be affected by the use of the area as a deposit for garden debris from a hotel that occupies the majority of this small island (Monsegur and Vargas 2010, personal observation). Since Agave eggersiana relies on asexual reproduction, the species depends on the bulbils becoming established. Covering the bulbils with debris may result in subsequent mortality of the bulbils and lack of natural recruitment, thus affecting the long-term survival of this population. Moreover, individuals located on the edges of the population are pruned as part of the gardens' maintenance. This practice may result in mortality or mutilation of individuals since the species is monopodial (single growth axis). The population at Protestant Cay is also threatened by competition with exotic plant species. Individuals seem to be stressed due to competition with exotics as what little undeveloped habitat is left is rapidly being colonized by nonnative species (see Factor E).
The individuals located at Gallows Bay are within an area currently developed as a residential complex with the potential for future expansion, which may affect these individuals (Monsegur and Vargas 2010, personal observation). In addition, this area does not contain additional habitat to allow the current population to expand. Remaining forested areas surrounding this location are characterized by the abundance of exotic species. Areas that could be used by bulbils to become established are occupied by the exotic plant Sansevieria cilindrica, a species that tends to form a complete cover of the understory (see Factor E).
The areas adjacent to Ha'penny Bay on the south coast of St. Croix harbor two of the known natural populations of Agave eggersiana (Ha'penny Beach and South Shore). According to personnel from the DPNR (Valiulis 2010, pers. comm.) these areas are advertised by realtors as areas for tourism and residential development and, as previously mentioned, are planned for high-density development. Furthermore, the areas along the south coast that have not been developed are used for cattle or hay production, minimizing the recovery of native vegetation and, therefore, the habitat for A. eggersiana (Monsegur and Vargas 2010, personal observation). The development of tourist and residential projects in these coastal areas may result in the extirpation of some populations, or at the least, will reduce the chances of the populations to expand or to colonize other areas. This is exacerbated by the low potential for natural recruitment due to the small number of populations and individuals.
The population of Great Pond is located between the entrance road of the East End Marine Park office and a private property currently for sale. The population seems to be healthy based on the presence of different size plants and evidence of recent flowering events. It seems that there is suitable habitat for the species in the area; however, the area near the population is mowed and the access road limits the expansion of the population's range. Furthermore, the area adjacent to this population is a private property for sale. The possible use of the area for residential or tourist development may affect the population; owners will likely manage their properties as landscapes, which could lead to land clearing, additional mowing, and other maintenance of gardens. This could also lead to the introduction of exotics. Moreover, the abundance of grassland areas and the dominance of the exotic Megathyrsus maximus (guinea grass) in the area make the population Agave eggersiana susceptible to human-induced fires (addressed in Factor E). These exotic grasses are typically adapted to fire conditions.
Based on the above information, we consider the present or threatened destruction, modification, or curtailment of the species habitat or range as a moderate but imminent threat to wild populations of Agave eggersiana. The threats of possible construction developments and current management of habitat of the populations may further limit species Start Printed Page 57724propagation and expansion in the foreseeable future.
Factor B: Overutilization for Commercial, Recreational, Scientific, or Educational Purposes
Agave eggersiana has been reported as a cultivar since it was described as a species in 1913 (Trelease, 1913, p. 28); historically, the majority of A. eggersiana found in St. Croix and St. Thomas were from landscaped areas (Britton and Wilson 1923, p. 156; Plaskett 2003, pers. comm.; Kojis and Boulon 1996, pers. comm.; Proctor and Acevedo-Rodri´guez 2005, p. 118; Acevedo-Rodri´guez 2005, pers. comm.). The species is currently distributed by the St. George Botanical Garden for conservation and private landscaping purposes. A. eggersiana is a commonly used ornamental species on the island, and recent declines in the number of individuals at one population along the coast of Ha'penny Bay are thought to be due to collection for ornamental purposes (Dalmida-Smith 2010, pers. comm.; Valiulis 2010, pers. comm.).
Based on the above, we consider the overutilization for commercial and recreational purposes a moderate to low but imminent threat to wild populations of the species. Although captively propagated Agave eggersiana are available to residents for use in private gardens, collection of wild individuals is a threat to the species, and we expect it to continue to be a threat in the foreseeable future.
Factor C: Disease or Predation
The genus Agave is widely affected by the agave snout weevil (Scyphophorus acupunctatus). This weevil has a wide distribution that includes the Greater Antilles (Cuba, Jamaica and Hispaniola) (Vaurie 1971, p. 4). The larvae of this weevil feed on the starchy base of the plant, increasing the risk of infestation by pathogens, such as a virus or fungus, later resulting in the death of the plant (Vaurie 1971, p. 4). At this time, there is no information about the occurrence of the agave snout weevil within the Puerto Rican Platform or the Lesser Antilles where St. Croix is located. A small number of individuals of A. eggersiana were observed with scarring along the borders of some leaves (Monsegur and Vargas 2010, personal observation). It appears that an insect or an arthropod larva may feed on the leaves; however, the exact cause and the consequences of the scarring are unknown. Nevertheless, this is important and it should be monitored as it might be an indicator of a recently arrived pest to St Croix.
On Mona Island (Puerto Rico), feral pigs are known to uproot juveniles and destroy the root system of Agave sisalana, to feed on the root system or to use them as a water source (Saliva 1983, 1996, personal observation). Since introduced pigs, donkeys, and goats have been reported in St. Croix we cannot discard the possible predation of A. eggersiana by these feral animals, particularly to young plants within the populations. The absence of evidence of predation by these species might be the result of the low number of populations of A. eggersiana, their isolation, and the proximity of some of these populations to human inhabited areas. However, at this time, there is no evidence that donkeys, pigs, or goats constitute a specific threat to any A. eggersiana populations.
Since the agave snout weevil has not been reported in St. Croix, we do not consider disease as a threat to the species. Although there is some evidence that insect or arthropod larvae may feed on the leaves of Agave eggersiana, there is no evidence that this is negatively impacting the species' ability to grow or reproduce. In addition, we have no evidence of grazing on A. eggersiana by introduced donkeys, pigs, or goats. Therefore, we do not find disease or predation to be a current threat to the species.
Factor D: The Inadequacy of Existing Regulatory Mechanisms
The Territory of the U.S. Virgin Islands currently considers Agave eggersiana to be endangered under the Virgin Islands Indigenous and Endangered Species Act (V.I. Code, Title 12, Chapter 2), and has amended an existing regulation (Bill No. 18-0403) to provide for protection of endangered and threatened wildlife and plants by prohibiting the take, injury, or possession of indigenous plants. Based on the number of individuals currently used for private gardens and current landscape practices in private areas, such as pruning and mowing of populations, we believe that protection provisions under the local regulation are not being appropriately enforced. Rothenberger et al. (2008, p. 68) mentioned that the lack of management and enforcement capacity continues to be a significant challenge for the USVI since enforcement agencies are chronically understaffed and territorial resource management offices experience significant staff turnover, particularly during administration changes.
Based on the information above, we consider the inadequacy of existing regulatory mechanisms as a current threat to the species due to a lack of enforcement. Because at least three populations exist in areas managed for conservation and public outreach, we consider this threat to be moderate to low in magnitude but imminent. We do not anticipate any regulatory or enforcement changes that would reduce this threat in the foreseeable future.
Factor E: Other Natural or Manmade Factors Affecting the Continued Existence of the Species
The islands of the Caribbean are frequently affected by hurricanes. It has been suggested that hurricanes are responsible for shaping and modifying the structure and composition of the vegetation in the Caribbean (Van Bloem et al. 2003, p. 137; Van Bloem et al. 2005, p. 572; Van Bloem et al. 2006, p. 517). As an endemic species to the island of St. Croix, Agave eggersiana would be expected to be well adapted to tropical storms. However, the low number of individuals found on the island and the reproductive biology of the species (dependence on asexual reproduction and the plant dying after flowering) increases the likelihood of stochastic events such as hurricanes extirpating a population. We believe that landslides and coastal erosion associated with hurricanes may affect the populations located along the coastal areas of St. Croix (Ha'penny Beach, South Shore, and Protestant Cay) due to their proximity to cliffs and the shoreline.
Agave eggersiana may be further threatened by climate change, which is predicted to increase the frequency and strength of tropical storms and can cause severe droughts (Hopkinson et al. 2008, p. 260). The cumulative effect of coastal erosion due to severe hurricanes plus the habitat modification for urban and tourist development can further diminish the availability of suitable habitat and, therefore, limit population expansion and colonization of new areas. In addition, the possibility of severe droughts may contribute to an increase in the quantity and frequency of fires on the island. These cumulative factors may reduce the number of individuals and further reduce populations.
Based on satellite images, there is evidence of human-induced fires along the south coast of the island. The vegetation of the Caribbean is not adapted to fires since this disturbance does not naturally occur on these islands (Brandeis and Woodall 2008, p. 557; Santiago-Garciá et al. 2008, p. 608); juvenile plants are especially vulnerable to fire damage. This regime of human-induced fires could modify the landscape by promoting exotic trees and Start Printed Page 57725grasses, and by diminishing the seed bank of native species. For example the exotic Megathyrsus maximus is well adapted to fires and typically colonizes areas that were previously covered by native vegetation. Furthermore, the presence of this species increases the amount of fuel and, therefore, the intensity of the fire events. Due to the abundance of grasses at Great Pond, this Agave eggersiana population is particularly threatened by human-induced fires.
Moreover, the individuals of the populations of Protestant Cay, Gallows Bay and Great Pond are surrounded by dense stands of different species of Sansevieria, an herb native to Africa. This invasive species seems to be occupying the ecological niche adjacent to the known populations of Agave eggersiana. Plant invasion can affect the environment at three levels; at the genetic level the number of individuals of native species can be reduced below the minimum necessary for persistence, at the species diversity level the number of species present and their distribution can be reduced, and at the ecosystem level the functioning of the ecosystem can be changed (Rippey et al. 2002, p. 170). In this case, invasive species may constrain the number of A. eggersiana reducing variability in the population. Consequently, the loss of diversity of the species may eliminate A. eggersiana in the area affecting other organisms (e.g., insects and birds feeding on the flowers).
Based on the above information and due to the reduced number of populations and individuals, we believe that the species is currently threatened by natural or manmade factors such as hurricanes, fires, and competition from exotic species. Climate change may exacerbate these habitat threats by increasing the frequency of fires, droughts, and hurricanes. We consider these threats to be moderate and imminent. We do not anticipate any changes that would appreciably reduce this threat in the foreseeable future.
As required by the Act, we conducted a review of the status of the species and considered the five factors in assessing whether Agave eggersiana is threatened or endangered throughout all or a significant portion of its range. We examined the best scientific and commercial information available regarding the past, present, and future threats faced by the species. We reviewed the petition, information available in our files, other available published and unpublished information, consulted with species and habitat experts and other Federal and State agencies, and conducted field work on the island of St. Croix.
This status review identified threats to the species attributable to Factors A, B, D, and E. Of the currently known populations, only three populations are located in areas managed for conservation and public outreach (Ruth Island, Salt River Bay, and Buck Island National Monument). The remaining populations, containing about 97 percent of the currently known adult individuals, are located in areas either threatened by development pressure, or are currently affected by landscape practices and competition with exotic species, resulting in detrimental effects to reproduction and recruitment (see Factors A and E). Furthermore, the use of the Agave eggersiana as an ornamental species is common on the island, and evidence suggests that wild specimens are being collected due to the commercial interest in this species (Factor B). Although the species is currently listed under local regulations, lack of enforcement of local law does not provide adequate protection to ameliorate threats to the species.
On the basis of the best scientific and commercial information available and our analysis of the current and foreseeable threats to the species and its habitat, we find that listing Agave eggersiana (including wild and cultivated populations), is warranted. We will make a determination on the status of the species as threatened or endangered when we do a proposed listing determination. However, as explained in more detail below, an immediate proposal of a regulation implementing this action is precluded by higher priority listing actions, and progress is being made to add or remove qualified species from the Lists of Endangered and Threatened Wildlife and Plants.
We reviewed the available information to determine if the existing and foreseeable threats render the species at risk of extinction now such that issuing an emergency regulation temporarily listing the species as per section 4(b)(7) of the Act is warranted. We determined that issuing an emergency regulation temporarily listing the species is not warranted for this species at this time since approximately 450 individuals are known to occur in 10 localities (Table 1). However, if at any time we determine that issuing an emergency regulation temporarily listing the species is necessary, we will initiate this action at that time.
Listing Priority Number
The Service adopted guidelines on September 21, 1983 (48 FR 43098), to establish a rational system for utilizing available resources for the highest priority species when adding species to the Lists of Endangered or Threatened Wildlife and Plants or reclassifying species listed as threatened to endangered status. The system places greatest importance on the immediacy and magnitude of threats, but also factors in the level of taxonomic distinctiveness by assigning priority in descending order to monotypic genera, full species, and subspecies (or equivalently, distinct population segments of vertebrates).
We assigned Agave eggersiana an LPN of 8, based on our finding that the species faces moderate to low magnitude threats from the present or threatened destruction, modification, or curtailment of its habitat; overutilization for commercial, recreational, scientific, or educational purposes; the inadequacy of existing regulatory mechanisms; and other natural or manmade Factors. One or more of the threats discussed above are occurring, and we anticipate they will still occur in the near future in each known population in St. Croix. These threats are ongoing and in some cases considered irreversible.
Although the species faces threats, as described above, we believe these threats to be of moderate to low magnitude; at least 450 adults and 260 bulbils are known to occur in 10 populations with half showing evidence of recruitment in the wild and 3 located in areas managed for conservation and public outreach. Under the 1983 Guidelines, a “species” facing imminent moderate to low magnitude threats is assigned an LPN of 7, 8, or 9 depending on its taxonomic status. Because A. eggersiana is a species, but not a monotypic genus, we assigned it an LPN of 8. While we conclude that listing the species is warranted, an immediate proposal to list this species is precluded by other higher priority listing actions, which we address below.
Preclusion and Expeditious Progress
Preclusion is a function of the listing priority of a species in relation to the resources that are available and competing demands for those resources. Thus, in any given fiscal year (FY), multiple factors dictate whether it will be possible to undertake work on a proposed listing regulation or whether promulgation of such a proposal is warranted but precluded by higher-priority listing actions.Start Printed Page 57726
The resources available for listing actions are determined through the annual Congressional appropriations process. The appropriation for the Listing Program is available to support work involving the following listing actions: proposed and final listing rules; 90-day and 12-month findings on petitions to add species to the Lists of Endangered and Threatened Wildlife and Plants (Lists) or to change the status of a species from threatened to endangered; annual determinations on prior “warranted but precluded” petition findings as required under section 4(b)(3)(C)(i) of the Act; critical habitat petition findings; proposed and final rules designating critical habitat; and litigation-related, administrative, and program-management functions (including preparing and allocating budgets, responding to Congressional and public inquiries, and conducting public outreach regarding listing and critical habitat). The work involved in preparing various listing documents can be extensive and may include, but is not limited to: gathering and assessing the best scientific and commercial data available and conducting analyses used as the basis for our decisions; writing and publishing documents; and obtaining, reviewing, and evaluating public comments and peer review comments on proposed rules and incorporating relevant information into final rules. The number of listing actions that we can undertake in a given year also is influenced by the complexity of those listing actions; that is, more complex actions generally are more costly. For example, during the past several years, the cost (excluding publication costs) for preparing a 12-month finding, without a proposed rule, has ranged from approximately $11,000 for one species with a restricted range and involving a relatively uncomplicated analysis to $305,000 for another species that is wide-ranging and involving a complex analysis.
We cannot spend more than is appropriated for the Listing Program without violating the Anti-Deficiency Act (see 31 U.S.C. § 1341(a)(1)(A)). In addition, in FY 1998 and for each fiscal year since then, Congress has placed a statutory cap on funds that may be expended for the Listing Program, equal to the amount expressly appropriated for that purpose in that fiscal year. This cap was designed to prevent funds appropriated for other functions under the Act (for example, recovery funds for removing species from the Lists), or for other Service programs, from being used for Listing Program actions (see House Report 105-163, 105th Congress, 1st Session, July 1, 1997).
Recognizing that designation of critical habitat for species already listed would consume most of the overall Listing Program appropriation, Congress also put a critical habitat subcap in place in FY 2002 and has retained it each subsequent year to ensure that some funds are available for other work in the Listing Program: “The critical habitat designation subcap will ensure that some funding is available to address other listing activities” (House Report No. 107 - 103, 107th Congress, 1st Session, June 19, 2001). In FY 2002 and each year until FY 2006, the Service has had to use virtually the entire critical habitat subcap to address court-mandated designations of critical habitat, and consequently none of the critical habitat subcap funds have been available for other listing activities. In FY 2007, we were able to use some of the critical habitat subcap funds to fund proposed listing determinations for high-priority candidate species. In FY 2009, while we were unable to use any of the critical habitat subcap funds to fund proposed listing determinations, we did use some of this money to fund the critical habitat portion of some proposed listing determinations, so that the proposed listing determination and proposed critical habitat designation could be combined into one rule, thereby being more efficient in our work. In FY 2010, we are using some of the critical habitat subcap funds to fund actions with statutory deadlines.
Thus, through the listing cap, the critical habitat subcap, and the amount of funds needed to address court-mandated critical habitat designations, Congress and the courts have in effect determined the amount of money available for other listing activities. Therefore, the funds in the listing cap, other than those needed to address court-mandated critical habitat for already-listed species, set the limits on our determinations of preclusion and expeditious progress.
Congress also recognized that the availability of resources was the key element in deciding, when making a 12-month petition finding, whether we would prepare and issue a listing proposal or instead make a “warranted but precluded” finding for a given species. The Conference Report accompanying Public Law 97-304, which established the current statutory deadlines and the warranted-but-precluded finding, states (in a discussion on 90-day petition findings that by its own terms also covers 12-month findings) that the deadlines were “not intended to allow the Secretary to delay commencing the rulemaking process for any reason other than that the existence of pending or imminent proposals to list species subject to a greater degree of threat would make allocation of resources to such a petition [that is, for a lower-ranking species] unwise.”
In FY 2010, expeditious progress is that amount of work that can be achieved with $10,471,000, which is the amount of money that Congress appropriated for the Listing Program (that is, the portion of the Listing Program funding not related to critical habitat designations for species that are already listed). However these funds are not enough to fully fund all our court-ordered and statutory listing actions in FY 2010, so we are using $1,114,417 of our critical habitat subcap funds in order to work on all of our required petition findings and listing determinations. This brings the total amount of funds we have for listing action in FY 2010 to $11,585,417. Starting in FY 2010, we are also using our funds to work on listing actions for foreign species since that work was transferred from the Division of Scientific Authority, International Affairs Program to the Endangered Species Program. Our process is to make our determinations of preclusion on a nationwide basis to ensure that the species most in need of listing will be addressed first and also because we allocate our listing budget on a nationwide basis. The $11,585,417 is being used to fund work in the following categories: compliance with court orders and court-approved settlement agreements requiring that petition findings or listing determinations be completed by a specific date; section 4 (of the Act) listing actions with absolute statutory deadlines; essential litigation-related, administrative, and listing program-management functions; and high-priority listing actions for some of our candidate species. The allocations for each specific listing action are identified in the Service's FY 2010 Allocation Table (part of our administrative record).
In FY 2007, we had more than 120 species with an LPN of 2, based on our September 21, 1983, guidance for assigning an LPN for each candidate species (48 FR 43098). Using this guidance, we assign each candidate an LPN of 1 to 12, depending on the magnitude of threats (high vs. moderate to low), immediacy of threats (imminent or nonimminent), and taxonomic status of the species (in order of priority: monotypic genus (a species that is the sole member of a genus); species; or part Start Printed Page 57727of a species (subspecies, distinct population segment, or significant portion of the range)). The lower the listing priority number, the higher the listing priority (that is, a species with an LPN of 1 would have the highest listing priority).
To be more efficient in our listing process, as we work on proposed rules for these species in the next several years, we are preparing multi-species proposals when appropriate, and these may include species with lower priority if they overlap geographically or have the same threats as a species with an LPN of 2. In addition, available staff resources are also a factor in determining which high-priority species are provided with funding. Finally, proposed rules for reclassification of threatened species to endangered are lower priority, since as listed species, they are already afforded the protection of the Act and implementing regulations.
Given the above-mentioned funding constraints, the Service's priority is to work on: (1) listing determinations for listing actions with absolute statutory, court-ordered, or court-approved deadlines, and final listing determinations for those species that have been proposed for listing; and (2) candidate species and reclassifications of other higher priority threatened species (i.e., species with LPN of 1). This work includes all the actions listed in the tables below under expeditious progress.
As explained above, a determination that listing is warranted but precluded must also demonstrate that expeditious progress is being made to add or remove qualified species to and from the Lists of Endangered and Threatened Wildlife and Plants. (Although we do not discuss it in detail here, we are also making expeditious progress in removing species from the list under the Recovery program, which is funded by a separate line item in the budget of the Endangered Species Program. As explained above in our description of the statutory cap on Listing Program funds, the Recovery Program funds and actions supported by them cannot be considered in determining expeditious progress made in the Listing Program.) As with our “precluded” finding, expeditious progress in adding qualified species to the Lists is a function of the resources available and the competing demands for those funds. Given that limitation, we find that we made progress in FY 2009 in the Listing Program and will continue to make progress in FY 2010. This progress included preparing and publishing the following determinations:

Our expeditious progress also includes work on listing actions that we funded in FY 2010 but have not yet been completed to date. These actions are listed below. Actions in the top section of the table are being conducted under a deadline set by a court. Actions in the middle section of the table are being conducted to meet statutory timelines, that is, timelines required under the Act. Actions in the bottom section of the table are high-priority listing actions. These actions include work primarily on species with an LPN of 2, and selection of these species is partially based on available staff resources, and when appropriate, include species with a lower priority if they overlap geographically or have the same threats as the species with the high priority. Including these species together in the same proposed rule results in considerable savings in time and funding, as compared to preparing separate proposed rules for each of them in the future.Start Printed Page 57731

|1 Funds for listing actions for these species were provided in previous FYs.|
|2 We funded a proposed rule for this subspecies with an LPN of 3 ahead of other species with LPN of 2, because the threats to the species were so imminent and of a high magnitude that we considered emergency listing if we were unable to fund work on a proposed listing rule in FY 2008.|
|3 Funds for these high-priority listing actions were provided in FY 2008 or 2009|
We endeavored to make our listing actions as efficient and timely as possible, given the requirements of the relevant law and regulations, and constraints relating to workload and personnel. We are continually considering ways to streamline processes or achieve economies of scale, such as by batching related actions together. Given our limited budget for implementing section 4 of the Act, these actions described above collectively constitute expeditious progress.
We intend that any proposed reclassification of Agave eggersiana will be as accurate as possible. Therefore, we will continue to accept additional information and comments from all concerned governmental agencies, the scientific community, industry, or any Start Printed Page 57734other interested party concerning this finding.
Agave eggersiana will be added to the list of candidate species upon publication of this 12-month finding. We will continue to evaluate this species as new information becomes available. This review will determine if a change in status is warranted, including the need to make prompt use of emergency listing procedures.
