Marine scientists at UC Santa Barbara have found that disturbances to giant kelp forests have a major influence on their net primary productivity (NPP)—an indicator of an ecosystem’s health and its ability to support its community—even more so than the availability of the resources needed for growth. Using data from decades of monthly measurements in the kelp forests at the campus’s National Science Foundation-supported Santa Barbara Coastal Long Term Ecological Research (SBC LTER) site, the researchers uncovered the direct, indirect and fascinating effects of disturbance on one of the world’s most productive ecosystems.
