Abstract	Currently, Sierra Nevada forests have high levels of mortality caused by bark beetles infesting trees stressed by drought, fire, overly dense stands, and pathogens. Fuel loads and fire hazard are high. Past logging and fire exclusion practices are partially responsible for this situation. Mitigative restoration requires thinning overly dense stands, primarily by controlled burning in parks and wilderness areas, combined with mechanical thinning and other selective tree-cutting practices elsewhere. Care will have to be taken to avoid creating more pest problems than are remedied, and some insect and disease activity should be tolerated as part of the restorative process. Failure to act may lead to continuation and perhaps worsening of present conditions. Widespread restoration should lead to sustenance of the biodiversity and productivity of these forests.
