Welcome to the Rangeland Resources Research Unit (RRRU). Our three-location Unit spans two states (Wyoming and Colorado), and two major semiarid rangelands of the western Great Plains (northern mixed-grass prairie and shortgrass steppe). The High Plains Grasslands Research Station (HPGRS), headquarters for the Unit, is located on 2,870 acres of northern mixed-grass prairie near Cheyenne, Wyoming. The 15,500 acre Central Plains Experimental Range (CPER) near Nunn, CO lies 35 miles to the south-east of the Cheyenne, WY on native shortgrass steppe. The CPER is a LTAR (Long-Term Agroecosystem Research) network site, as well as the core site for Domain 10 of NEON (National Ecological Observatory Network). In Fort Collins, near Colorado State University, is the third location, the Crops Research Laboratory.
The Unit conducts research within two major research areas:
Research objectives include:
Global Change in Semi-Arid Rangelands: Ecosystem Responses and Management Adaptations:
Improved Management to Balance Production and Conservation in Great Plains Rangelands:
