Physical Descriptive Data for Plots

(Complete FGDC-compliant metadata is in preparation for these data)

These data were collected under contract by The Nature Conservancy, through a contract with the Environmental Research Systems Institute. They consist of descriptions
of the physical description for each site, site code, site name, GPS coordinates, elevation, slope, aspect, topographic setting, landform, surface geology, cowardin system
type, surface materials, leaf characteristics, and physiography. If your browser has tables capability, see the table version of this file. For download, Excel(*.xls) and
MDbase (*.mdb) formats are available.

Other Data for Plots include Species Listing Data.
