Animal and Plant Health Inspection Service, USDA.
Notice of availability and request for comments.
We are advising the public that an environmental assessment has been prepared by the Animal and Plant Health Inspection Service relative to the environmental release of the gall wasp Aulacidea acroptilonica for the biological control of Russian knapweed (Acroptilon repens). The environmental assessment documents our review and analysis of environmental impacts associated with, and alternatives to, the release of this biological control agent. We are making this environmental assessment available to the public for review and comment.
We will consider all comments that we receive on or before May 27, 2008.

Russian knapweed (Acroptilon repens) is an aggressive, long-lived perennial in the Asteraceae or sunflower family that thrives in both irrigated and arid environments, and in cropland, pastures, rangeland, shrubland, and wasteland. It is difficult to control in alfalfa, clover, other forage crops, and pastures. It reduces wildlife habitat and suppresses the growth of other plants.
Russian knapweed has no known beneficial qualities. It is not utilized for forage because of its bitter taste, and may cause neurological disorders in horses if consumed. The quality of flour or other grain products that have been contaminated by Russian knapweed is reduced due to the bitter taste it imparts. Studies indicate that the spread of Russian knapweed may have a significant economic impact.
Russian knapweed reproduces primarily vegetatively from a primary vertical root with numerous lateral roots. It is a strong competitor and produces compounds that exclude other plant species. Russian knapweed seeds may be spread through infested hay or crop seeds or through the movement of cattle, as the seeds are able to survive the digestive system of these animals.
Estimated Russian knapweed acreage for the Western United States and Canada for the year 2000 totaled over 1,561,714 acres, with 80 percent of the affected acreage located in the States of Washington, Idaho, Colorado, and Wyoming. Start Printed Page 22128
Aulacidea acroptilonica is a small gall-forming wasp that has been demonstrated through specificity testing and field observations reported in scientific literature to attack only Russian knapweed. Gall induction diverts nutrients from flower formation, seed production, and the normal growth of plant tissues, thus reducing the plant's competitive ability and seed production.
APHIS' review and analysis of the potential environmental impacts associated with the use of Aulacidea acroptilonica as an agent for the biological control of Russian knapweed are documented in detail in an environmental assessment entitled “Field Release of Aulacidea acroptilonica (Hymenoptera: Cynipidae), an Insect for Biological Control of Russian Knapweed (Acroptilon repens) in the Continental United States” (January 22, 2008). We are making this environmental assessment available to the public for review and comment. We will consider all comments that we receive on or before the date listed under the heading DATES at the beginning of this notice.
The environmental assessment may be viewed on the Regulations.gov Web site or in our reading room (see ADDRESSES above for instructions for accessing Regulations.gov and information on the location and hours of the reading room). You may request paper copies of the environmental assessment by calling or writing to the person listed under FOR FURTHER INFORMATION CONTACT. Please refer to the title of the environmental assessment when requesting copies.
The environmental assessment has been prepared in accordance with: (1) The National Environmental Policy Act of 1969 (NEPA), as amended (42 U.S.C. 4321 et seq.), (2) regulations of the Council on Environmental Quality for implementing the procedural provisions of NEPA (40 CFR parts 1500-1508), (3) USDA regulations implementing NEPA (7 CFR part 1), and (4) APHIS' NEPA Implementing Procedures (7 CFR part 372).Start Signature
