Old Naturalist Files, Crater Lake National Park.
Protection of park forests against forest fires was one of the principal concerns of park management during the war. The park fire protection program was divided into three categories for management purposes: prevention, presuppression, and suppression. Prevention included public control and education and fire hazard reduction. Presuppression comprised organized personnel training, acquisition of fire equipment, and physical improvements. The latter included protection motorways, fire, horse, and foot trails, and fire breaks; lookout stations on the Watchman and Mount Scott; four ranger stations at the north entrance, Annie Spring, Lost Creek, and park headquarters; five patrol cabins at National, Bybee, Red Blanket, and Bear creeks and Maklak Spring, a radio and telephone communication system; and fire toolboxes and caches. Suppression of fire was to be accomplished primarily by trained park personnel employing hand tools. Cooperative fire fighting agreements were in force with all adjoining forest protection agencies. To strengthen the park’s fire-fighting capability a detailed Memorandum of Understanding between the Departments of the Interior and Agriculture for mutual aid in fire control was approved in January 1943. [39]
By the early 1940s a soil and moisture conservation program had been initiated at Crater Lake. The program, as described in November 1944, had two principal objectives for resource management:
1. To stop erosion on slopes, cuts, fills, embankments, borrow pits and quarry sites, and to promote growth of grasses, plants, shrubs, bushes and trees on all such areas where vegetation is now lacking, in order to restore these slopes to a more pleasing and natural condition and at the same time materially reduce the present heavy annual maintenance costs of removing eroded material.
2. To stop erosion of Crater Walls at developed or improved areas in an effort to preserve and protect the rim of the crater and save trees, bushes, shrubs, plants, and grassed areas from destruction. To prevent erosion of the soil on which improvements exist, viz, sidewalks, parapet walls, buildings, landscape planting, etc. [40]
