Nicosia EL. 2015. Monitoring salt marsh vegetation and nekton at Sagamore Hill National Historic Site: 2015 summary report. Natural Resource Data Series. NPS/NCBN/NRDS—2015/996. National Park Service. Fort Collins, Colorado

The Northeast Coastal and Barrier Network (NCBN) began monitoring salt marsh vegetation and nekton at Sagamore Hill National Historic Site (SAHI) in 2009. This report summarizes the fourth year of data collected during the summer of 2015. Monitoring will continue on a biennial basis. Fifty-one vegetation plots were sampled on August 19-20, 2015. Plots established and sampled during the 2009 field season were re-visited in 2015. The percent cover of each vegetation species and non-vegetation cover type within each 1 m2 plot was visually estimated using a revised Braun-Blanquet method. Twelve vegetation species and four non-vegetation cover types (bare ground, wrack & litter, trash, and water) were observed. Sixteen nekton stations were established along Eel Creek in 2015. Each station was sampled using a 1m2 aluminum throw trap. Nekton sampling occurred twice during the summer (July 7 and August 19-20). A total of eight species (including fish, crabs, and shrimp) were recorded. Examination of percent catch data indicates that P. pugio (72.3%), and F. heteroclitus (22%), account for approximately 94% of all nekton captured at SAHI in 2015.
