Jornada Experimental Range Utilization Surveys
Listed in NASA Earthdata CMR
The "Jornada Experimental Range Utilization Surveys" contains data on the utilization of grasses by livestock.
Description
Utilization was determined by taking large samples of grazed and ungrazed heights for major grass species. Using height-weight tables, it was possible to determine the percent utilization, or percent of forage used, for pastures or ranges.
These data are used to determine how much forage was consumed by livestock on the range. Collection Organization: Jornada Experimental Range. Collection Methodology: Utilization of grasses by livestock was determined by taking large samples of grazed and ungrazed heights for major species and then using height-weight tables to determine the percentage utilization for pastures or range-sites.
