Underwater Forests Survey

Participants survey kelp on the shoreline by running a monthly survey at a given location at the lowest tide of the month.

The survey consists of: Taking a photo of the kelp patch from a distance. Heading down to the kelp patch and completing three surveys at different points within the patch by counting kelp within a quadrat. If the patch is large enough, a fourth quadrat may also be surveyed. A photo and latitude/longitude is required for each quadrat. Data is submitted to an online form.
