2009: Photo 1: Rockweed harvest damage adjacent to undamaged rockweed bed in Photo 2.

Cobscook Bay, East Bay 9/10/09	2009: Photo 2: Healthy unharvested rockweed adjacent to site of Photo 1. The rockweed supplies a thick cover over the rock ledge, protecting the organisms below from heat, sun and drying. Cobscook Bay, East Bay 9/10/09
