Forest dynamics in different scenarios: Selective logging in the middle Magdalena (Colombia)
Selective logging is a frequently used forest use activity that has been shown to have less impact on biodiversity than clear-cutting. However, both the magnitude and direction of ecological change after logging depend on its intensity and subsequent forest dynamics. Therefore, it is important to conduct studies to understand the functioning of different ecosystems after selective logging. This study analyzed forest dynamics in the El Paujil reserve (Middle Magdalena, Colombia) in terms of demography, regeneration, clear-cutting dynamics, biomass accumulation and floristic composition by comparing two one-hectare plots in a fragment of the little disturbed (primary) forest and two one-hectare plots in a fragment of the forest that was selectively logged in the past. As expected, forest structure and biomass accumulation are altered by selective logging, but it did not have a significant impact on the other aspects mentioned, since it seems that the steep slopes of the area cause high mortality and promote the formation of clearings in both logged and lightly disturbed forests.
期刊介绍:
Journal of Sustainable Forestry publishes peer-reviewed, original research on forest science. While the emphasis is on sustainable use of forest products and services, the journal covers a wide range of topics from the underlying biology and ecology of forests to the social, economic and policy aspects of forestry. Short communications and review papers that provide a clear theoretical, conceptual or methodological contribution to the existing literature are also included in the journal.
Common topics covered in the Journal of Sustainable Forestry include:
• Ecology, management, recreation, restoration and silvicultural systems of all forest types, including urban forests
• All aspects of forest biology, including ecophysiology, entomology, pathology, genetics, tree breeding, and biotechnology
• Wood properties, forest biomass, bioenergy, and carbon sequestration
• Simulation modeling, inventory, quantitative methods, and remote sensing
• Environmental pollution, fire and climate change impacts, and adaptation and mitigation in forests
• Forest engineering, economics, human dimensions, natural resource policy, and planning
Journal of Sustainable Forestry provides an international forum for dialogue between research scientists, forest managers, economists and policy and decision makers who share the common vision of the sustainable use of natural resources.
