Summary

Invasive plant risk and climate change vulnerability for significant habitats scored by hexagon for land managers.

Description

Invasive Plant Risk and Climate Change Vulnerability Scores for significant habitats was scored within 2.5 square mile hexagons in the California Central Coast region (including Santa Cruz, Monterey, San Benito, San Luis Obispo, Santa Barbara, and Ventura County, excluding the Channel Islands). Only hexagons that contained significant habitats were scored.
