Summary
Forest surveys were conducted in nine 20 m x 25 m study plots, split into 3 representatives each for three forest types in Great Dismal Swamp, VA and NC, USA, December 2015 - February 2018. Trees, saplings, and shrubs were identified to species and measured for estimates of standing stocks. Standing stock data include: tree diameter at breast height (dbh), height, and condition; sapling dbh; shrub diameter at root collar, and height. In each plot, roughly 10 co-dominant trees were equipped with dendrometer bands and measured annually for growth estimates.

Purpose
The purpose for collecting this data was to contribute to an integrated study incorporating an assessment of ecosystem services with carbon monitoring to help understand and quantify the effects of selected management and restoration actions in Great Dismal Swamp. The objectives were to characterize habitat conditions and changes in aboveground biomass, noting differences between the habitat types with regard to standing stocks and annual tree growth. These results will be combined with other components of the study to inform refuge management on ways to address strategy goals by considering the impacts of alternative management approaches on ecosystem services including carbon sequestration potential in Great Dismal Swamp.
