This book was released on 2003 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: The forests of the Kenai Peninsula, Alaska, underwent a major spruce beetle(Dendroctonus rufipennis (Kirby)) outbreak in the 1990s. A repeated inventory of forest resources was designed to assess the effects of the resulting widespread mortality of spruce trees, the dominant component of the Kenai forests. Downed woody materials, fuel heights, and moss depths were recorded during each inventory. Changes in downed and dead woody materials are summarized by forest type and harvest activity, compiled by fuel timelag classes. Fuel heights, fine fuels, and sound large fuels increased between 1987 and 2000. Moss depths and rotten large fuels decreased. Harvested white spruce (Picea glauca (Moench) Voss) showed the greatest increase of fine fuel classes.

Download or read book The Effect of Wildfires Spruce Bark Beetles and Prescribed Burns on Residential Property Values in Alaska s Kenai Peninsula written by Paul C. Reinker and published by . This book was released on 2019 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study estimates the effect that forest fires, spruce bark beetle outbreaks, and controlled burns performed by fire management agencies have on nearby residential property values. Using the hedonic pricing framework, and ten years of house sales from south-central Alaska's Kenai Peninsula, this study found little evidence that wildfires and spruce beetle outbreaks have a significant effect on the final sale price of surrounding homes, but found that the controlled burns contribute to a decrease in surrounding home values. As Alaska's climate becomes warmer and drier, these disturbances threaten to increase in frequency and severity. Understanding how homeowners perceive fire risk and forest damage is increasingly important to fire management policy, as the behavior of residents can help limit both the cost from and incidence of wildfires. The study's findings suggest that homeowners are either insulated from, or indifferent to fire risk, but targeted burns of high-risk areas by fire managers could increase awareness and sensitivity to fire risk.

Download or read book The Forest Ecosystem of Southeast Alaska written by John S. Hard and published by . This book was released on 1974 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
