Litter, water depth and graminoid height data for C3 and Marsh Creek experimental blocks, Seney National Wildlife Refuge, Michigan, 2006-2010

In association with plant cover data, data on litter depth, water depth, and graminoid height were collected on 16, 1-ha experimental blocks in C3 and Marsh Creek units of Seney National Wildlife Refuge, 2006-2010. Within each unit, we selected 4 pairs of blocks representing sedge-shrub habitat, with one of the pair assigned to spring burning (C3, May 2008) or summer burning (Marsh Creek, 2007 and 2008). This before-after-control-impact design provided for data collection two growing seasons before the burn (2006, 16 blocks; 2007, 15 blocks) and two-three growing seasons (2008, 2009, and 2010; 14 blocks) after burning; the unburned plot of each pair served as the control, and the burned plot of each pair the treatment. Within each block, 25 points were established equidistant (25 m) from one another, 5 each along 5 transects. Data were collected at along a 2-m ruler set out at each points. The ruler was marked into 40 5-cm segments; these data were recorded only at the each fifth segment (5, 10, 15, 20, 25, 30, 35, and 40) as a single measure (not averaging accross the 5 segments). This table provides unsummarized data. Associated plant cover data are in Seney_ExpFireStudy_Plant_Taxa_Cover_data.csv.
