Overview of Agents and Patterns of Mortality and Resulting Coarse Woody Debris Recruitment in Western Forests
We present an overview of many of the mortality agents in western coniferous forests of the United States that are responsible for coarse woody debris recruitment under natural conditions. Patterns and scale of occurrence of mortality agents for the six western USDA Forest Service Regions are examined at both historic and projected-risk time periods. The data indicates that bark beetles have be...
متن کاملAccumulation and Connectivity of Coarse Woody Debris in Partial Harvest and Unmanaged Relict Forests
When a tree dies, it continues to play an important ecological role within forests. Coarse woody debris (CWD), including standing deadwood (SDW) and downed deadwood (DDW), is an important functional component of forest ecosystems, particularly for many dispersal-limited saproxylic taxa and for metapopulation dynamics across landscapes. Processes, such as natural disturbance or management, modif...
متن کاملManaging Coarse Woody Debris in British Columbia’s Forests: A Cultural Shift for Professional Foresters?
Coarse woody debris (CWD) is recognized as an important component of British Columbia’s forest ecosystems linked to biodiversity and ecosystem processes. CWD represents high centers of biological interaction and energy exchange, symbolizing in many ways the complexity of forest ecosystems. Our research on lichens and bryophytes demonstrates that many species are either partially or entirely dep...
متن کاملRegional Distribution and Dynamics of Coarse Woody Debris in Midwestern Old-Growth Forests
Old-growth forests have been noted for containing significant quantities of deadwood. However, there has been no coordinated effort to quantify the deadwood component of old-growth remnants across large regions of temperate deciduous forest. We present results of a regional inventorythatquantifies and examines regional and temporal trends fordeadwood in upland old-growth forest remnants within ...
