This data set shows forests of North America, classified according to FAO ecological zones (EZ). The data set was created by modifying the Ecological Regions of North America (ecoregions) data included in the North American Atlas. Ecoregion classifications were converted to the FAO EZ classes, based on the Forest Resource Assessment (FRA) 2010, and minor adjustments were made to polygon geometry. In addition, data were added for Hawaii and Puerto Rico, and additional lakes were imported. The FAO ecological zones are based on a combination of climate (temperature and precipitation) and potential vegetation classifications. They are broad areas of relatively homogeneous vegetation, with similar physical characteristics....

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. This point feature class contains 81,481 points arranged in a 270-meter spaced grid that covers the Spring Mountains and Sheep Range in Clark County, Nevada. Points are attributed with hydroclimate variables and ancillary data compiled to support efforts to characterize ecological zones.
