Brooke analyzed 111 plant species in the California Floristic Province. Her conclusion -- species with restricted range sizes and low topographic heterogeneity across their distribution were predicted to be the most exposed to climate change, while species at low elevations were the most exposed to habitat loss via land use change. However, even some broadly distributed species were projected to lose >70% of their currently suitable habitat due to climate and land use change if they are in geographically vulnerable areas
