Mapping Russian Knapweed and Silverleaf Nightshade
- With project partners and members of the public, the WMA is targeting these two species as priorities for mapping in Sutter and Yuba Counties.
Past Project Highlights:
Yuba County fire area yellow starthistle eradication
- With project partners, Natural Resources Conservation Service and UC Cooperative Extension, the Yuba/Sutter WMA aerially reseeded 100 acres of land in Yuba County with non-invasive grasses to prevent invasive weed infestation. The project area was previously covered with yellow starthistle, and had recently burned.
Sutter County weed mapping project
- In 2001, Sutter County created maps of weed presence throughout the county. The maps documented presence of Arundo donax and aquatic species, including parrotfeather.
