Project Highlights:

   Lake Tahoe Basin wide multi-weed removal project

  • This weed removal project focuses on a Basin wide eradication of spotted knapweed, tall whitetop, diffuse knapweed, Dalmatian and yellow toadflax, Canada thistle, oxeye daisy, sulfur cinquefoil and Klamathweed. Early detection and rapid response are the primary goals for this area because populations are still small. Methods of control and treatment of invasives by hand crews are hand pulling, digging, mulching and herbicide application. All populations are mapped and resurveyed annually. Strategic goals (what’s being protected): water quality and clarity, wildlife habitat, threatened plant species – Tahoe yellow cress, protection from increased fire risk from invasives (e.g. Scotch broom). In this project all partners are involved.
