Maritime Chaparral

Description

Several years after its natural fire cycle, maritime chaparral is once again dominated by woody shrubs such as manzanitas (Arctostaphylos spp.) and California lilac (Ceanothus spp.). This rare habitat is found only in areas with a predominance of summer fog; often patches of maritime chaparral only a few 10's of miles away have their own distinct manzanita species.

Maritime chaparral is considered a threatened habitat type, and so is protected by many agencies along the coast of California. For instance, the California Coastal Commission considers areas of this habitat type 'environmentally sensitive habitat areas' (ESHA), affording it the highest level of protection of any habitat in California.

Many rare plant and animal species are only found in these patches of habitat; most require 'renewal' of the habitat by fire. Currently, we are faced with important questions about the composition and distribution of the habitat and how best to conserve it in the face of increasing fragmentation and fire suppression. Our recent surveys suggest that it is impossible to restore maritime chaparral: if you know differently, please contact us!

The Coastal Training Program will continue its focus on maritime chaparral as it is one of the most threatened habitat types of the Elkhorn Slough watershed. We are currently exploring the efficacy of conservation regulations and the potential for new conservation tools such as conservation banks. This website will continue to serve as a hub for information on maritime chaparral ecology, conservation, and restoration.
