Project Highlights

Interstate 80 corridor weed control

The Nevada/Placer WMA worked with PG & E, Placer County Agriculture Department, and many ski resorts to survey 3,204 acres of forested lands along I-80 from Colfax to Donner Summit. Spotted knapweed, tall whitetop and scotch thistle were documented, then treated with herbicides or removed by hand. Ski resorts involved include Soda Springs, Sugar Bowl, Donner Ski Ranch, Boreal, Alpine Meadows, Squaw Valley USA, Northstar at Tahoe, and Homewood.

Red Sesbania control in the American River watershed

In cooperation with the Sacramento WMA, the cities of Roseville and Rocklin, Placer County, and the Sacramento Area Flood Control Agency, the Nevada/Placer WMA controlled red sesbania along streams in the American River watershed. Treatment started in Loomis and continued downstream along Dry Creek and its tributaries. Treatment techniques included hand removal and cut-stump, and the original treatment will be followed by 5 years of follow-up monitoring and control.

Truckee Basin weed control

The Nevada County Department of Agriculture controlled musk thistle, knapweed species, short and tall whitetop, and yellow starthistle with herbicide treatments. The entire Truckee Basin from Donner Summit to the Nevada border has been treated.
