Data Archives: Changes in Eelgrass Cover
in Great Bay from 1986 to 1992

Changes in eelgrass (Zostera marina) cover in Great Bay from 1986 to 1992. This series of maps which are published in the Technical Characterization of Estuarine and Coastal New Hampshire, show the change in eelgrass cover from the mid 1980’s through the early 1990’s. The declines were attributed to an outbreak of the eelgrass wasting disease that is caused by the slime mold Labyrinthula zostrea. This decline was followed by rapid recovery through natural seed production and revegetation. The maps were generated from data collected by Short et al. 1986, Short and Mathieson 1992, Short et al. 1992, 1993 and Burdick and Short 1995.
