Volunteer conservation jobs are available this spring, summer and fall through the Student Conservation Association Inc., a nonprofit national educational organization that provides volunteers for work with the National Park Service, the U.S. Forest Service and the Bureau of Land Management.

In 1982, the association will place 975 volunteers in those agencies, in the Nature Conservancy and other private conservation agencies.

Programs are available throughout the United States in such places as Yellowstone National Park in Wyoming, the north woods of Maine on the Appalachian Trail, Assateague Island National Seashore in Maryland, Grand Canyon National Park in Arizona, Big Bend National Park on the Rio Grande in Texas and Olympic National Forest in Washington.

Volunteer positions are offered on a competitive basis for high school students from 16 to 18 years old and for men and women 18 and older.

The high school program offers work, educational and recreational experiences for three to five weeks. Two to four weeks are devoted to conservation work and one week is spent hiking and exploring a wilderness area. Work projects include such tasks as trail maintenance and construction, re-vegetation of overused areas, boundary fencing and construction of bridges and shelters.

In the Park, Forest and Resource Management Assistance Program, adults 18 and older spend between eight and 12 weeks in jobs ranging from giving interpretive programs for park visitors to conducting field research or assisting rangers in back-country patrol.
