sustained yield
Quick Summary
Sustained yield is a management principle focused on the continuous production of biological resources, such as timber or fish. The core idea is to harvest only what can be replaced by regrowth or reproduction before the next harvest occurs. This concept is crucial in forestry, where it ensures a steady income for industries by balancing annual harvests with annual growth, while also accounting for losses from fire, insects, and diseases.12
The practice involves long-term planning, with rotation periods varying based on the resource. For example, eucalyptus for pulpwood might have a 10-year rotation, while pine for sawlogs could take 100 years. Sustained yield also applies to minor forest products like turpentine and rubber, where resources are managed to ensure continuous availability.2
