[Docket No. APHIS-2008-0042]

Control of Russian Knapweed; Availability of an Environmental 

AGENCY: Animal and Plant Health Inspection Service, USDA.

ACTION: Notice of availability and request for comments.


SUMMARY: 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 

DATES: We will consider all comments that we receive on or before May 
27, 2008.

ADDRESSES: You may submit comments by either of the following methods:

    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.

    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 

    Done in Washington, DC, this 18th day of April 2008.
