Jayson Smith

A marine conservationist, Jayson Smith studies human disturbances on ecosystem functioning and community structure in coastal marine habitats. Southern California’s dense human population affects urban coastal ecosystems in numerous ways. Of particular interest Smith are the impact of invasive seaweeds on marine ecosystems, the effects of human visitation in rocky intertidal habitats, long-term change in coastal community structure and dynamics, and the effects of climate change. All of these areas have implications for in policy-making decisions, particularly with current emphasis on ecosystem-based management.

Smith is a member of the Laguna Ocean Foundation Board, the Orange County Marine Protected Area Council, the Multi Agency Rocky Intertidal Network (MARINe), and other organizations and government agencies.
