Southeast Alaska's remaining virgin forests have few insect pests. The black-headed budworm and the hemlock sawfly, both western hemlock defoliators, are the most important species. They kill some trees, kill tops in others, and cause growth loss, but stands survive their attacks. Extensive conversion of virgin stands to second growth may result in an increase in pest problems as it has in similar areas such as coastal British Columbia. ‍?‍?Widespread use of insecticides to control major outbreaks is not practical because of risk of contaminating salmon-spawning and trout-rearing streams; but insecticide use may be justified in local, high value areas. Weather, diseases, and parasites control outbreaks naturally. Damage-prone stands should be identified and harvested before insect attack or salvage-logged following outbreaks. Ideally, second-growth stands should be managed for resistance to insect pests.

The effects of logging and associated activities on fish habitat in southeastern Alaska are discussed, and fish habitat research applicable to southeast Alaska is summarized. Requirements of salmonids for suitable spawning and rearing areas are presented. Factors associated with timber harvest which may influence these habitats are discussed in detail; e.g., sediment, stream temperature, streamflow, logging debris, and chemicals. Recommendations for further research are made.
