Since 1930, the University of Michigan has maintained the Edwin S. George Reserve (ESGR) for the purposes of providing research and education opportunities in the natural sciences and preserving the native flora and fauna. The ESGR is a 525-hectare (ca. 1300 acre) fenced preserve located in Livingston County, Michigan (about 25 miles Northwest of Ann Arbor), which was presented to the University as a gift by Edwin S. George in 1930. The ESGR is characterized by a rugged moraine and basin topography supporting a rich fauna and flora (species lists). The ESGR is administered by the Department of Ecology and Evolutionary Biology at the University of Michigan.

Michigan Big Woods research plot data

These data are in the standard ForestGEO format. Each of the three censuses has its own text file. Within that file each row represents a stem measured in that census. Species information can be found in the species file. The personnel responsible for this work can be found in the personnel file. See the readme file for more information.

Data and Resources

See cited article for full methods. Briefly, these data come from three censuses of a 23 ha forest research plots. All free-standing vegetation greater than 1 cm diameter at 1.3 m height (diameter at breast height; DBH) were tagged, identified, spatially mapped and had their DBH measured. The original census took place in 2008 and covered only 12 ha. A second census took place from 2008-2010 and expanded the plot to its current 23 ha. Finally a third census took place in 2014. In the second and third censuses the original trees were found, recorded for survival, remeasured, and new individuals were tagged. This plot is part of the Smithsonian Institution's Forest Global Earth Observatory (ForestGEO) global network of forest research sites.
