Salt Marsh Vegetation and Nekton Community Monitoring at Assateague Island National Seashore. 2008 Summary Report.

摘要

This annual report summarizes the first year of data collected at Assateague Island National Seashore (ASIS) located in Maryland and Virginia. Fifty vegetation plots and a subset of pools, creeks and shoreline were sampled for nekton at nine marshes June-September, 2008. Monitoring data is to be collected at these same marsh sites biennially. Nekton in marsh pools, large tidal creeks, and shoreline habitats (all less than 1m deep) were sampled with a 1m2 aluminum throw trap. Vegetation was monitored using 1m2 plots and a revised Braun-Blanquet method (Kent and Coker 1992) to estimate percent cover of each vegetation species and non-vegetation cover type within each plot.
