Ecological stability of forests and sustainable silviculture. These alternative harvesting systems are more aligned with natural processes by retaining large live trees, snags, and downed logs after harvest Franklin et al. The disturbance caused to CWD was assumed to depend on species and decay class. Alternatives to traditional clearcut harvesting have been examined due to a recognized need to protect forests. Immediate effects of four different felling methods on mature boreal spruce forest understorey vegetation in southern Finland.
Conservation actions at and some species are confined to certain areas. For H2, mean abundance, reproduction, and recruitment of M. Threads of continuity: Forest naturalness in northern Europe: The amount of CWD decreased also inside the retention tree groups; in the 1st post-treatment season, 4. However, a significant treatment by block interaction necessitated analysis of each block study area separately.
Retention Forestry in Southern Patagonia: Multiple Environmental Impacts and Their Temporal Trends
Decomposition rate constants of Picea abies logs in southeastern Norway. Although these partial cutting results are encouraging for maintenance of M. Objectives of the experiment In a large scale field experiment to reveal the impacts of tree retention and fire - obviously the two key modifiers of forest biodiversity - on species occurrence patterns was initiated. A scientifically validated management approach that can reduce such conflicts is retention forestry, an approach modeled on natural processes, which emerged in the last 25 years as an alternative to clearcutting. For future application, it will be important to 6.
Photographs fall of treatment sit.. The Theory of Island Biogeography. Don and western hemlock Tsuga heterophylla Raf. Our overview from different parts of the world suggests that retention forestry has benefits in landscapes with widely varying land-use histories. With increasing knowledge about forest types and conservation among forest managers and also encour- and their associated biodiversity, the potential for higher ages innovation in the development and improvement of specificity will increase. We tested the hypotheses H that on newly clearcut sites, H 1 abundance and species diversity of the forest-floor small mammal community, and H 2 abundance, reproduction, and recruitment of M.
