There are 195 invasive plant species in the county making up 8% of the total vegetative cover. We engage our staff, and many volunteer groups, in an effort to control the most problematic weeds.
In many cases these species were introduced as ornamental, but just because they are pretty, doesn’t mean they belong. Species such as Acacia, Eucalyptus, Scotch Broom and European Dune Grass quickly overwhelm native vegetation and reduce habitat values for wildlife.
Sonoma County has over 2200 native plant species, 22 of which are endangered. Several plants are “endemic” meaning they only occur here. We partner with the California Native Plant Society to locate rare and threatened populations and protect them from invasive.
