Theory and Practice of Yield Regulation Systems for Sustainable Management of Tropical and Subtropical Moist Natural Forests

  • Chapter
Sustainable Forest Management

Part of the book series: Managing Forest Ecosystems ((MAFE,volume 1))

Abstract

The broader context and prerequisites for sustainability of timber harvesting in tropical and subtropical natural forests are outlined. With sustainability as guiding principle, four components of yield regulation systems were identified: yield optimisation, stand regeneration strategies, tactical components of harvesting cycle, and harvest tree selection criteria. Yield regulation systems occupy positions on a gradient of high to low impact on the forest ecosystem: from manipulation to mimicking of forest structure and dynamics. Most systems occupy high impact positions on this gradient in attempting to achieve productivity enhancement, stand regeneration and favourable operational economics. The complexities of these issues are discussed, suggesting the opportunities and advantages of rather selecting low impact yield regulation approaches. Existing yield regulation systems are critically assessed. An example of a naturalistic yield regulation system, as practised in a South African natural forest, is described.
