Napa River rare plant monitoring

Megan Keever, botanist, is presenting a poster summarizing a 10-year study of Mason’s Lilaeopsis along 7 miles in the Napa River watershed at the 4th annual botanical symposium of the Northern California Botanists in Chico Monday and Tuesday, January 10 and 11, 2011. Mason’s Lilaeopsis is a California state rare plant. The monitoring was conducted to ensure Napa County Flood Control and Water Conservation District’s restoration activities within the watershed were meeting appropriate mitigation targets.
