Summary

We identified nine study site locations, representing three mature vegetation communities [Atlantic White Cedar (desired community), tall pine pocosin (desired community), and red maple/black gum mixed (undesired community)] with typical water depth within each vegetation type. All measurements were replicated three times (3 vegetation types x 3 replicates = 9 sites total). We installed four flux chambers at each site to collect GHG fluxes from all nine sites. We measured CO2 and CH4 using a Los Gatos Research Ultra Portable Greenhouse Gas Analyzer and two-part 760 cm2 flux chambers (chamber base remained in situ; chamber top was placed on the bottom only when sampling). We checked the gas fluxes on a monthly time-table for 24 months [...]

Purpose

Data were obtained to assess how forest type, hydrologic conditions and management strategies affect GHG soil flux at the Great Dismal Swamp National Wildlife Refuge. The goal is to relate changes in GHG fluxes to shifts in refuge hydrologic management on forested peatlands.
