Historical records indicate that Flax Pond, a small Spartina alterniflora marsh located on the north shore of Long Island, New York, was opened to marine waters in 1803. This opening is recorded in the sediments by a sharp transition from sedge (brackish or fresh water) peat to Spartina (salt marsh) peat. This dated horizon was used to calculate an average net rate of vertical accretion of 2.5 mm/yr and a maximum net rate of 4.7 mm/yr. These estimates may serve to predict the rate at which Spartina marshes are able to recover from physical disturbance. *** DIRECT SUPPORT *** A00BY066 00002
