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.

Available in PDF, EPUB and Kindle. Book excerpt: Beginning in the late 1980s, a series of improbable bark beetle outbreaks unsettled iconic forests and communities across western North America. An insect the size of a rice kernel eventually killed more than 30 billion pine and spruce trees from Alaska to New Mexico. Often appearing in masses larger than schools of killer whales, the beetles engineered one of the world's greatest forest die-offs since the deforestation of Europe by peasants between the eleventh and thirteenth centuries. The beetle didn't act alone. Misguided science, out-of-control logging, bad public policy, and a hundred years of fire suppression created a volatile geography that released the world's oldest forest manager from all natural constraints. Like most human empires, the beetles exploded wildly and then crashed, leaving in their wake grieving landowners, humbled scientists, hungry animals, and altered watersheds. Although climate change triggered this complex event, human arrogance assuredly set the table. With little warning, an ancient insect pointedly exposed the frailty of seemingly stable manmade landscapes. Drawing on first-hand accounts from entomologists, botanists, foresters, and rural residents, award-winning journalist Andrew Nikiforuk, investigates this unprecedented beetle plague, its startling implications, and the lessons it holds.
