Data are not collected on Federal land. Data are not available for Alaska or the Pacific Basin. Data for Puerto Rico and the U.S. Virgin Islands are aggregated by 6-digit hydrologic unit. NRI maps reflect national patterns rather than site- specific information. No data are collected for any year that land is in this ownership.
Land cover is the vegetation or other kind of material that covers the land surface.
Pastureland may consist of a single species in a pure stand, a grass mixture or a grass-legume mixture. Management usually consists of cultural treatments-fertilization, weed control, reseeding, or renovation and control of grazing. Please include the Product ID you are inquiring about.
