Colin Talbert Brian Reichert 201810 vector digital data Fort Collins, CO USGS Fort Collins Science Center https://doi.org/10.5066/P9M00P17 Patricia Stevens Brian Reichert 20180724 project Fort Collins, CO USGS Fort Collins Science Center https://nabatmonitoring.org/#/home/welcome This sampling frame is a set of grid-based finite-area frames spanning Canada, the United States, and Mexico. The grid for the United States is broken into individual grids for the continental United States, Hawaii, and Puerto Rico. Alaska is combined with Canada into a single grid. Each country/state/territory extent consists of four nested sampling grids at 50x50km, 10x10km, 5x5km, and 1x1km resolutions. The original 10x10km continental United States grid was developed by the Forest Service, U.S. Department of Agriculture for use in the interagency "Bat Grid" monitoring program in the Pacific Northwest and was expanded program in the Pacific Northwest and was expanded across Canada, the United States, and Mexico for the North American Bat Monitoring Program (NABat). Additional grids for Hawaii and Puerto Rico were created for this data release. This vector dataset is the individual grid-based sampling grid for Puerto Rico at a 1x1km resolution. This grid-based sampling frame was created to formalize a sampling strategy for the North American Bat Monitoring Program (NABat). The 10x10km grid is being used for bat monitoring but an additional lower resolution grid (50x50km) and higher resolution grids (5x5km and 1x1km) grids were added so that the same sampling frame could be used for monitoring species or areas requiring finer or coarser resolutions. 2018 publication date Complete None planned -68.1136 -64.3169 18.9033 17.5362 Puerto Rico ISO 19115 Topic Category biota location USGS Thesaurus ecosystem monitoring USGS Metadata Identifier USGS:5b7c371de4b0f5d578860378 Common geographic areas Puerto Rico None.
