Distinctiveness (1=highest,4=lowest): 1 (globally outstanding)
This ecoregion includes diverse and globally rare habitat types.  A large number of endemic species of plants and animals are present.  Habitats include chaparral, oak woodlands and conifer woodlands.  The ecoregion has over 150 species of butterflies and the highest species richness of native bees.*

Conservation Status (1=most endangered, 5=most intact): 1 (critical)
Only 15% of the coastal sage scrub remains and most oak savannas have been destroyed.  The habitats are extremely fragmented due to intensive development.  Invasion of alien species, fire supression, grazing, and smog are threats.*
