This report analyzes the risk of impacts from invasive plants to more than seven hundred populations of fifty federally listed plant species in the central coast of California. Results include population-, species-, and geographically-based invasive plant risk scores that land managers can use to prioritize invasive plant management for the purpose of rare plant protection.
The report also includes a summary of a detailed, four-year field study of invasive plant associations, local demographic patterns, and seed resources of three target listed plants: Pismo Clarkia, Gaviota tarplant, and Camatta Canyon amole.
