Book excerpt: In 1972 a field study of spruce beetle (Dendroctonus rufipennis) population dynamics was established in central British Columbia (BC) in two adjacent timber harvesting areas. Data from the 7-year field study was analysed with respect to the effects of spruce windthrow, stumps, and other logging residue on variation in the following factors of spruce beetle populations: adult emergence, adult size and sex ratio, brood development, and brood survival.--Includes text from document.

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.
