Monitoring Reports 62661

Monitoring will be conducted for the first two years starting in October 2022. The site will be monitored by plot transect method, using 15-meter transects laid at an approximate 45-degree angle across the width of the terrace, generally arranged from south (origin) to north (terminus) to measure community metrics on both sides and at the crown of each terrace. Transect locations will be selected randomly throughout the constructed sites using an aerial map of the complex overlain with a numbered grid pattern; specific transect locations will be selected using a random number generator to select squares within the grid. The terminus of each transect will be marked with a PVC stake, and the GPS coordinates and calculated elevation recorded with a Trimble R2 GNSS receiver. Three 1m2 plots (Figures 1 and 2) will be located along each transect; one at each end and one at the midpoint. 15 transects (45 plots) will be sited across the entire project (inclusive of site 1 and 2). Each plot will be assessed for relative aerial coverage according to standards laid out under the National Fish and Wildlife (NFWF) National Coastal Resilience Fund, including each plant species, live oyster, live mussels, and wrack. Spartina alterniflora (aka Sporobolus alterniflorus) density, chlorophyll production, and biomass will also be assessed where applicable to assess plant productivity.
