NCALM Seed Project. PI: Brady Hardiman, Ohio State University. The survey area is an irregular polygon enclosing a portion of the University of Michigan Biological Station (UMBS) located at the northern tip of the Lower Peninsula of Michigan, on the southwest shore of Douglas Lake. The survey polygon is approximately 40 square kilometers in size. The polygon at its widest region in the east west direction is 8.27 km, and 6.27 km at its longest North to South direction region. The data were collected to study the effects of forest canopy structural change on carbon uptake and storage.
