How We're Organized
The Arapaho and Roosevelt National Forests and Pawnee National Grassland is part of the Rocky Mountain Region, which manages resources and activities across more than 22 million acres of forests and grasslands in Colorado, Kansas, Nebraska, South Dakota and Wyoming. A forest supervisor leads each of the 11 national forest and grassland units, which are divided into ranger districts managed by district rangers.
The Arapaho and Roosevelt National Forests and Pawnee National Grassland (ARP) includes 1.5 million acres of forests and grassland in Northern Colorado. ARP Forest Supervisor Glenn Casamassa and Deputy Forest Supervisor Ron Archuleta, lead a team of four group officers and five district rangers. Casamassa is also the lead forest supervisor for all of the national forests in Colorado and supervisor of the Capital City Coordinator Cheri Ford, who works closely with the Colorado Department of Natural Resources, the Colorado Legislature and the Colorado Governor's office.
The Forest Supervisor's Office, located in Fort Collins, houses the forest supervisor and four program groups: the Ecosystem Support Group (ECO); the Recreation, Heritage Resources, Planning and Design Support Group (RPD); the Engineering, Lands and Minerals Support Group (ELM); and the Administrative Operations Support Group (AO).
