Jornada Experimental Range (USDA-ARS) annual stocking rates for cattle, horses, and sheep, 1916-2001

This data package contains data on stocking rates for cattle, horses, and sheep on all pastures of the USDA-ARS Jornada Experimental Range beginning in 1916. Grazing goats were infrequent and are therefore included as part of the sheep category. Stocking rates are expressed in animal unit month (AUM), which is based on metabolic weight and average amount of forage needed by each animal unit per month. Total AUM is calculated for each year for each animal unit. This study was completed in 2001 and will not be updated.NOTE: The USDA-ARS discontinued regular updates to this dataset after 2002 because of de-stocking.

本数据包收录了自1916年起，美国农业部-ARS乔尔纳达实验站所有牧场牛、马、羊的放牧密度数据。放牧山羊的频率较低，因此被纳入绵羊类别中。放牧密度以动物单位月（AUM）为单位表示，该单位基于动物的代谢重量以及每个动物单位每月所需的平均牧草量。每年对每个动物单位计算总AUM。该研究于2001年完成，将不再更新。注意：由于减牧，美国农业部-ARS自2002年起不再定期更新此数据集。数据包中的资源包括：资源标题：网站指针指向HTML文件。文件名：网页，URL：https://portal.edirepository.org/nis/mapbrowse?scope=knb-lter-jrn&identifier=210412001，包含信息和数据文件下载链接的网页。
