Continuous Forest Inventory Plots for the UMN Cloquet Forestry Center

Abstract

The University of Minnesota Cloquet Forestry Center is a field research and instructional station associated with the College of Food, Agricultural, and Natural Resources Sciences (CFANS). Continuous Forest Inventory data has been collected for the CFC since 1959. The network of permanent forest measurement plots consists of 406 1/7 acre plots with a subset of these plots re-measured up to seven times since establishment. The last re-measurement occurred Summer 2014. The majority of the CFI plots were geolocated with a Trimble GeoXT GNSS receiver in 2014 or 2015 to obtain sub-meter precision for each plot center. Plot locations are marked in the field with a tagged center post with painted tree numbers oriented to plot center. Eight plots without precision GNSS locations are indicated within the attribute table. One plot location is missing from this dataset as it could not be relocated in the field (Plot_ID = '620'). The most recent report on the UMN Cloquet Forestry Center CFI is available as 2016 Staff Paper No. 243 published through the UMN Department of Forest Resources and summarizes findings from the 2014 remeasurement.
