8 200.2 Field organization.

The field organization of the Forest Service consists of regions, stations, and areas as described below:

(a) Regions of the National Forest System. For the purpose of managing the lands administered by the Forest Service, the United States is divided into nine geographic regions of the National Forest System. Each region has a headquarters office and is supervised by a Regional Forester who is responsible to the Chief for the activities assigned to his region. Within each region are located national forests and other lands of the Forest Service.

(1) National forests. Each forest has a headquarters office and is supervised by a Forest Supervisor who is responsible to the Regional Forester. Each forest is divided into ranger districts.

(2) Ranger districts. Each district may include a portion of a national forest, a national grassland or portion thereof, a national recreation area, a wilderness or primitive area, and other lands administered by the Forest Service. Each district has a headquarters office and is supervised by a District Ranger who is responsible to the Forest Supervisor.

(b) Experiment stations for forest and range research. To facilitate forestry research in the field, the United States is divided into eight geographic regions referred to as experiment stations. Each station has a headquarters office and a Director who is responsible to the Chief for all research activities assigned to his station. The Forest Products Laboratory

State in which forest is located

and Institute of Tropical Forestry are additional research organizations headed by Directors. Each experiment station has research project locations and laboratories dispersed within the geographic boundaries of experiment stations.

(1) Laboratories. Research activities are in 82 locations, including 47 modern research laboratories.

(2) Field facilities. Within experiment stations there are 96 experimental forests and ranges and 101 research natural

areas.

(c) Areas for State and private forestry cooperation. Field-level cooperation between the Forest Service, States, and the private sector on forestry activities is accomplished within two geographic areas in the Eastern United States, and within the national forest regions in the Western United States. Each of the two Eastern areas has a headquarters office and is supervised by an Area Director, who is responsible to the Chief for the activities assigned to his Area. Regional Foresters in Western Regions 1 through 6 and 10 are responsible for State and private forestry activities within their regions.

(d) Field addresses. The addresses of Regional Foresters, Experiment Station Directors, and Area Directors are given below. Under each Regional Office address is a list of National Forests by States with locations of Forest Supervisor headquarters. Headquarters locations for Ranger Districts, National Crasslands, and National Recreation Areas are not listed but may be obtained from Forest Supervisors.
