Season and interval of burning and cattle exclusion in the southern Blue Mountains, Oregon: Environmental attributes

These data document environmental variables including overstory canopy cover, O horizon depth, ground cover and soils for a prescribed burning study with unburned controls on the Malheur National Forest in the southern Blue Mountains of Oregon. The original prescribed fires were conducted in the fall of 1997 and spring of 1998 and were repeated at two intervals, five and fifteen years. Five year interval reburns have been repeated three times (four burns total) and the fifteen year interval a single time (two burns total). Data include environmental conditions prior to and following the last reburns except for soils data which were collected prior to the last reburns only. Specifically, this data publication includes overstory tree canopy cover data from the 10-meter radius plots, ground cover data (litter, rock, bare soil and coarse woody debris) from the 1 x 1 meter quadrats, O horizon depth data from the 10-meter radius plots, and soils data (e.g. carbon, nitrogen and phosphorous concentrations, pH and bulk density) from 2012.
