Physical Descriptive Data for Plots
Physical Descriptive Data for PlotsThese data were collected under contract by The Nature Conservancy, through a contract with the Environmental Research Systems Institute. They consist of descriptionsof the physical description for each site, site code, site name, utm coordinates, elevation, slope, aspect, topographic setting, landform, surface geology, cowardin system type, hydrography, surface materials, soil texture and drainage, 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.
