Description

Interpretation of underburning effects in mixed conifer/pinegrass plant communities (Blue Mountains, Oregon) suggest: underburns occurred at 10-year intervals; ponderosa pine is being replaced by white fir; pine stands did not develop according to "normal stand development"; pine stands require stocking level control to prevent stagnation; range condition must be rated on successional vegetation not climax; range grasses show "downward range trend" due to increasing tree cover complicating trend interpretation; herbaceous plants can sustain livestock use since they developed genetically under periodic 100 percent use by fire; livestock fill a major biotic niche not occupied by wildlife; some plants are dependent upon fire for regeneration; some wildlife depend upon stocking level control and successional trees (pine and larch) formerly provided by underburning; soils developed under fire and are brown forest rather than podzolic; fire hazard is changing from light, flashy fuel under open tree cover to heavy fuels under dense tree cover.
