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 you do not have tables capability, see the < PRE > tagged text file with your browser. For download,
Excel(*.xls) and MDbase (*.mdb) formats are available.

Other Data for Plots include Species Listing Data.
