Selective logging in the Amazon rainforest (original) (raw)
Selective logging or partial forest removal is the practice of cutting down a few species of trees while leaving the rest intact and unharmed. Selective logging is often considered a better alternative to clear cutting.Selective logging in the Brazilian Amazon Rainforest was recently shown in analyses of Landsat Enhanced Thematic Mapper Plus data at high spatial resolution to be occurring at rates of about 12,000–20,000 km2 per year, thus indicating the central role of selective logging in tropical forest disturbance. Although selective logging has far less impact on forest processes than deforestation, selectively logged sites have higher rates of forest fires, tree fall, changes in microclimate, soil compaction and erosion, among other ecological impacts on biodiversity and ecosystem fun

| dbo:abstract | Selective logging or partial forest removal is the practice of cutting down a few species of trees while leaving the rest intact and unharmed. Selective logging is often considered a better alternative to clear cutting.Selective logging in the Brazilian Amazon Rainforest was recently shown in analyses of Landsat Enhanced Thematic Mapper Plus data at high spatial resolution to be occurring at rates of about 12,000–20,000 km2 per year, thus indicating the central role of selective logging in tropical forest disturbance. Although selective logging has far less impact on forest processes than deforestation, selectively logged sites have higher rates of forest fires, tree fall, changes in microclimate, soil compaction and erosion, among other ecological impacts on biodiversity and ecosystem functioning. Selective logging is a dominant form of land use in the Brazilian Amazon. Canopy gap fractions patterns are found to result from selective logging caused tree falls, roads, skid trails, and log decks, which are areas where logs are staged for transport. These gaps can vary between logging operations. Logging activities has now increased from initially low volume harvests of floodplains to much higher rates that remove around 25 million cubic metres (880×106 cu ft) of wood from the forest each year. The ecological, social, and economic impacts drive a better understanding of efficient forest management techniques and deforestation. (en) |
