Bull Kelp Monitoring

Bull kelp (Nereocystis luekteana) is the largest species of brown algae native to our region. This fast growing seaweed can grow up to 100 feet in a single year and is an important component of the rocky intertidal ecosystem of the Salish Sea. Bull kelp sequesters carbon, oxygenates the marine environment, protects against storm surge and shoreline erosion, and provides critical nutrients and habitat for a number of species in the Salish Sea. Animals critical to the food web, including herring and salmon, use bull kelp forests for protection and food during certain life stages.

 

 

 

 BOAT-BASED SURVEYS

Working in partnership with the Northwest Straits Commission, the Whatcom MRC conducts annual kayak-based surveys of selected bull kelp canopies during low-tide events between July-September. Using handheld GPS units and kayaks, volunteers map the perimeter of the beds and collect additional data including water temperature and bed depth estimates to provide valuable information on the status of bull kelp along the Whatcom County shoreline. The data is shared with the Northwest Straits Commission for comparison with similar information collected by other MRC counties.
