Cover photo. County herbicide truck bound for the National Forest, spraying onto the banks of the Methow River in 1999 on McFarland Creek Road. As the hot sun evaporated the miles of treated roadsides, petrochemical fumes filled the entire drainage (click for high resolution image).

Photographs for this report are from page 3 of the printed version (click the image to view a larger version).

Photo 1. Cattle feeding on knapweed which survived herbicide treatment. Okanogan NF, WA. Carrying manure treated with picloram back onto agricultural lands is a violation of the herbicide label directions, while carrying weed seeds back causes weeds to spread onto private lands.

Photo 2. Damaged and dying ponderosa pines and killed bitterbrush (foreground) following herbicide treatment. Okanogan NF, WA.


Photo 3. Herbicide-resistant knapweed along a heavily treated road. Okanogan County, WA.

Photo 4. Eroding river banks with sparse cover of native plants killed or damaged (arrow) by spraying herbicide at stream. Sparse weeds on site (foreground) survived. Okanogan NF, WA.
