Summary

This dataset provides an additional "Grazing Potential" land use class to the previously published U.S. Geological Survey (USGS) National Water-Quality Program (NAWQA) Wall-to-Wall Anthropogenic Land-use Trends (NWALT) product (Falcone, 2015, USGS Data Series 948). As with the NWALT, the dataset consists of five national 60-m land use grids, for the years 1974, 1982, 1992, 2002, 2012. The only change to the dataset is, for every year, some pixels which are class 50 "Low-use" in the NWALT, are reclassified to a new class 46 "Grazing Potential Expanded". The purpose of the re-classification is to identify areas which are likely to have had at least some grazing activity based on agreement of historical land cover/use datasets, and not [...]

Purpose

The purpose of the dataset is to add to Grazing Potential information in the NWALT, specifically to map areas which are not currently classified as Grazing Potential, but feasibly could be.
