Use the pictures and descriptions to identify an invasive plant and then fill out the weed location form each time you identify a weed in a new location.

The booklet was assembled by the Eastern Sierra Weed Management Area, a local organization that brings together landowners and managers (private, city, county, State, Federal) for the purpose of controlling invasive weed species. A copy of the book can be picked up at the Bishop Field Office, from Anne Halford - Botanist.
