Project Highlights:

   Lake County arundo mapping and treatment

• GPS technology was used to survey and create GIS maps for arundo and tamarisk species over 70-75% of Lake County. Of the mapped area, 60% has been treated for arundo using two forms of chemical treatment. Most plants were originally treated using the cut-and-daub method, and then any re-growth was treated a second time by bending the plant down and spraying it with a dilute herbicide. Project partners included the East Lake and West Lake Resource Conservation Districts, Lake County Public Works, and the Agricultural Commissioner’s Office.

   Broom grazing at the Robinson Rancheria

• Broom species were grazed by goats on 1.5 acres at the Robinson Rancheria in Nice, on the northern end of Clear Lake. A follow-up treatment with clove oil on new shoots and re-growth during intense summer heat was very effective.
