In 1953, the University of Michigan, Department of Forestry, published this report documenting Saginaw Forest. This report lists information about specific lots within the forest including planting data, notes about damage from insects, weather, or fire, the number of trees of each species, their basal area, height, diameter at breast height, and some data related to thinning or harvesting that was conducted before 1953.http://deepblue.lib.umich.edu/bitstream/2027.42/90965/1/A Guide to Saginaw Forest 1953.pdf
