SPRUCE S1 Bog Vegetation Survey and Peat Depth Data: 2009

This data set reports the results of a field survey of the S1 Bog to characterize the vegetation and
to determine peat depth. The survey was conducted on September 21 and 22, 2009. This initial survey of
vegetation and peat depth characteristics of the target bog was conducted to evaluate the logical
locations for installing replicated experimental blocks for SPRUCE. The goal was to identify multiple
locations of uniform aboveground vegetation and belowground peat depth for positioning experimental
units within the bog. The experimental work was conducted in a Picea mariana [black spruce] - Sphagnum
spp. bog forest in northern Minnesota, 40 km north of Grand Rapids, in the USDA Forest Service Marcell
Experimental Forest (MEF). There is one (*.csv) data file containing the vegetation survey data and
observations, and the peat depth measurements. Also included are figures of the spatial distributions of
vegetation survey and peat depth results (Vegetation_survey_2009_figures.pdf). Photos of the surveyed
plots are included in several *.zip files.photos.
