Description of dataset and Methodological Information These data were generated to investigate the edge influence of linear disturbances in treed poor and moderate-rich fens. Vegetation data was collected along transects of three treatments: 1) Single wide treatment: transects start on conventional wide seismic lines (approx. 4-12 m wide) and extend into the adjacent treed peatland (n = 5 in moderate-rich fens; n = 7 in poor fens) 2) Single narrow treatment: transects start on low-impact narrow seismic lines (approx. 1.5-3 m wide) and extend into the adjacent treed peatland (n = 6 in moderate-rich fens, n = 5 in poor fens) 3) Multiple narrow treatment: transects start on low-impact narrow seismic lines and extend to the the nearest parallel low-impact narrow seismic line (n = 14 for both peatland types) For the single wide and single narrow treatments, sampling locations were established at 1, 2.5, 5, 10, 15, 20, 25, 35, 50, and 75 m from the edge of the seismic line into the forest, with plots centered on these locations. For the multiple narrow treatment, sampling points were established at 1, 2.5, 5, 10, 15, 25 m from the edge of both the starting and ending seismic line. To characterize vegetation on the seismic lines, two sampling points were established 1.4 m apart on the line and to either side of the starting point of each transect. At each sampling location, cover of each species of understory vascular plants was visually estimated in 1 m2 circular plots. Canopy cover was estimated at the center of each plot using a convex spherical densiometer. Within each tree plot (2 m x 4 m plot centered on sampling location with the long axis of the plot perpendicular to the edge), we recorded the DBH and species of all trees (woody species with DBH > 1 cm) and calculated tree density and tree basal area.
