Abstract

Eelgrass in Great Bay itself decreased substantially (43%) between 2005 and 2006, due to losses in both biomass and distribution. Little Bay and the Piscataqua River showed greater change(loss of 40%) between 2005 and 2006 than previously, with very low levels of eelgrass compared to historical distributions and the large beds of ruppia in the Bellamy, Oyster and upper Piscataqua Rivers also diminished. The Portsmouth Harbor – Little Harbor area experienced a decrease in eelgrass abundance (14%) between 2005 and 2006. All of the Great Bay Estuary has decreased eelgrass beds compared to historic distributions. In the decade from 1996 to 2006, the Great Bay Estuary has lost almost half its eelgrass.
