The eradication area consists of approximately 626 acres in southeast Eugene, Lane County, that will be aerially treated with B.t.k. It is likely that a small buffer area surrounding the eradication area will receive some B.t.k., but in quantities much less than inside the eradication area. Movement of B.t.k. beyond the eradication area is likely to be affected by conditions such as temperature, humidity, wind direction, wind speed, and terrain. Standard buffer areas used around control areas in gypsy moth suppression programs in the eastern US are typically 200 to 500 feet.
The proposed gypsy moth eradication area encompasses two sites where single gypsy moths were caught in 2007 and four sites where six gypsy moths were caught in 2008, including three moths that were caught in one trap. The eradication area includes four city parks: Kinney Frank Park, Shadow Wood Park, Skyline Park, and a newly acquired parcel of 40 acres in the Amazon Creek headwaters. Most of the eradication area is within the Eugene city limits, except for another park, Dylard Skyline Park (that borders Skyline Park). The exact location is within T18S R3W S16, 17, 20, and 21. The East Fork Amazon Creek runs from the south to north along the western portion of the eradication area. The northwest corner of the boundary begins at N 44.00753, W –123.07815 (GPS readings of the latitude and longitude), at the end of Y Way, and proceeds due east for approximately 5150 feet, along 43rd Avenue, and 400 feet east of Spring Blvd. at N44.00750, W –123.05853. From this point it turns 90 degrees south and proceeds 5295 feet to a point 370 feet south of Hidden Meadows Dr. and 300 feet west of Allbritain Ln. at N 43.99297, W –123.05858. The boundary continues due west for 5150 feet to a point 1785 feet south of the intersection of Martin St. and Amazon Dr. at N 43.99303, W –123.07816. From this point the boundary turns 90 degrees north and continues for 5,295 feet to the starting point.

There are over 1500 residences and one school (Eugene Christian School) within the eradication area. Most residences are single-family homes, but there are some apartment complexes. There is also an assisted living residence. There are no businesses in the 626-acre area. The area is hilly and ranges in elevation from 450 feet along Amazon Creek to 1200 feet on Mt. Baldy peak. Trees are abundant within the area and include a mixture of Douglas fir (up to 200 feet tall), oak, maple, ash, and filbert. There is an understory of blackberry, vine maple, willow, sword fern, rhododendron, holly, and other plant species in the Amazon Creek headwaters. Many residential yards have landscaping and numerous other plant species. In addition, a long power line traverses the southern east-west length of the eradication area.
