Colorado State University maintains a large number of field sites. The Colorado State Forest Service manages the 29,000 ha Colorado State Forest located 130 km west of Fort Collins and the State Forest Service Nursery at the CSU Foothills campus. The Agronomy Research Center provides over 80 ha of farmland. The Colorado State Agricultural Experiment Station maintains nine Research Centers located throughout the state for research on agronomic and horticultural crops, land management, rangeland ecology, and livestock production.
Many federal and state lands are readily accessible and used extensively by GDPE students and faculty. Nearby Rocky Mountain National Park not only provides a vast recreation resource for the public, but also provides designated natural areas for research purposes. The Shortgrass Steppe Research and Interpretation Center is the gateway the 6000 ha Central Plains Experimental Range managed by the Agricultural Resarch Service and the the 80000 ha Pawnee National Grassland managed by the US Forest Service. It is also the location of the Shortgrass Steppe Long Term Ecological Research project. Located on the west side of the Continental Divide is the USFS Fraser Experimental Forest, primarily subalpine habitat permanently maintained for basic and applied research in the areas of timber, watershed, and wildlife management. The U.S. Forest Service also maintains the Manitou Experimental Forest (primarily ponderosa-bunchgrass) near Colorado Springs.
Other federal land units in the area include the Arapaho and Roosevelt National Forests, which contain over 500,000 ha of mountain forest and rangeland between Denver and Wyoming. Colorado Division of Parks and Outdoor Recreation, through its Northern Regional Office in Fort Collins, administers six state parks (34,000 ha), areas valuable for wildlife and recreation-related research. Several nearby federal and state agencies have traditionally maintained cooperative research ties with Colorado State. These include: USDA (Agricultural Research Service, Economic Research Service, Forest Service); U.S. Department of Interior (National Biological Survey, Cooperative Wildlife and Fishery Units, National Park Service); Centers for Disease Control; Colorado Division of Wildlife; and Colorado State Forest Service.
