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.

Book excerpt: This publication presents highlights of a recent south-central Alaska inventory conducted by the Pacific Northwest Research Station Forest Inventory and Analysis Program (USDA Forest Service). South-central Alaska has about 18.5 million acres, of which one-fifth (4 million acres) is forested. Species diversity is greatest in closed and open Sitka spruce forests, spruce woodlands, closed tall alder shrub type, and low shrub willow type. Of the forest land, 1.9 million acres are classified as timberland (unreserved productive forest land). About 1.3 million acres of forest land are reserved from harvest; these reserved forest acres are primarily on the Kenai National Wildlife Refuge, national parks, and the Chugach National Forest. The volume of timber on timberland was estimated at 5,087 million cubic feet; the plurality of volume44 percentis on state and local government lands with the remaining volume primarily on private lands (28 percent) and national forests (23 percent). Fifty-seven percent of timberland acres and 93 percent of the growing-stock volume is in sawtimber stands, with Sitka spruce forest type predominating. Most timberland in south-central Alaska is of relatively low productivity, producing less than 50 cubic feet per acre per year. For timberland acres on state and private lands, average annual mortality and harvest exceeded average annual growth.

Download or read book Storing Beetle killed Logs Under Snow to Reduce Losses After Mountain Pine Beetle Attack written by Roger J. Whitehead and published by . This book was released on 2008 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: To assess the potential to store beetle-killed logs under insulated snowpacks in British Columbia to preserve wood quality and maximize value recovery, we reviewed the literature and visited operations in eastern Canada, where the technique has been recently adapted to routine operations, and in Finland, where 3.5 million m3 of timber are stored under snow annually. We also visited storage terminals in Sweden where very large volumes of sawtimber have been stored since 2005. We identified three roles that cold storage could play in responding to the current mountain pine beetle outbreak: (1) where the outbreak is expanding rapidly and green-attack volume exceeds capacity of mills to process all logs prior to dispersal flight, cold storage can prevent development and dispersal of beetles before milling late in the season; (2) where significant value is lost between harvesting and processing due to checking after delivery to the mill, cold storage can maintain moisture content and extend the time frame for achieving higher economic recovery; and, (3) where there is an opportunity to store large volumes of quality logs, doing so for an extended period (more than one year) may help defer or moderate anticipated social, environmental and economic impacts in the areas most affected by the mountain pine beetle outbreak. We report on discussions with woodland and plant managers in British Columbia on how the technique might be adapted to western Canadian operations and possible impediments to implementation, and we present recommendations.
