Mechanics of Monitoring Forest Clearcuts and Their Regeneration
نویسندگان
چکیده
A framework for the identification and monitoring of forest clearcuts and their regeneration is presented. LANDSAT digital data are classified to detect clearcuts and their major regeneration components, including brush, grass, bare soil, and conifer. Historical LANDSAT digital data are used to provide a changedetection analysis of forest conditions. Area summaries of land cover are obtained for the entire study area or for subunits. A graphic digitizer is used to provide an overlay to the LANDSAT ,digital land cover classification in order to summarize land cover area by physical and/or political boundaries. Individual clearcuts are analyzed within each summary unit for the size of the clearcut, the type of regenerated land cover, and other site-specific accounting information; Output products include tabular summaries of the area of each land cover, and black and white or color maps of geographically referenced land cover data. Ancillary data affecting land cover management decision-making, such as topography ~r climate can be graphically interfaced with LANDSAT-derived land cover information and "specialized" composite maps produced. These "specialized" maps provide an added dimension in resource management planning.

Long-term responses of disturbance-associated birds after different timber harvests
Timber harvest provides favorable habitat for many species of shrub-dependent birds. Because of historical dominance, effect of clearcutting on early successional birds has been widely studied, but less information is available on alternatives such as shelterwood and group selection, which have become a more dominant means of regenerating pines (Pinus spp.) on federal lands of the southeastern ...

Balancing timber production and conservation in forest management requires an understanding of how timber harvests affect wildlife species. Terrestrial salamanders are useful indicators of mature forest ecosystem health due to their importance to ecosystem processes and sensitivity to environmental change. However, the effects of timber harvests on salamanders, though often researched, are stil...

The regeneration is one of the most important phenomena in forest ecosystems and the most important factor of development and sustainability of forests. Assessment of the regeneration is one of the best criteria for monitoring forest function stability. The aim of this study was to investigate the spatial variability of regeneration diversity and its relationship with tree species diversity in ...
متن کاملAssessing quality of clearcut habitats for amphibians: Effects on abundances versus vital rates in the southern toad (Bufo terrestris)
Forest clearcutting is a form of habitat alteration that drastically alters the landscape and may contribute to declines in amphibian populations. Indeed, many studies have documented decreases in amphibian abundances and species richness in clearcuts. The development of effective conservation strategies to reduce the effects of timber harvesting has been hindered by lack of knowledge of the me...
