Figure 21a. Eelgrass beds growing between sand waves (near Little 

 Harbor Beach, Great Neck Wareham) . Eelgrass cover on this habitat did 

 not change appreciably between the two years shown. This demonstrated 

 that colonization and growth kept up with losses from sand wave 

 migration. Most of these beds, however, were destroyed by ice scour and 

 winter storms during the late 1970's.
