Document Summary
Promotes regeneration of closely aged trees (low forest heterogeneity) Promotes regeneration of trees of various ages and thus sizes (higher horizontal and heterogeneity) vertical. Primary examples in canada: clearcutting, shelterwood cutting, strip cutting, seed tree. Silvicultural systems that maintain trees across a wide range of age and size classes. Simulate removal of old, large trees from wind, insects, disease. Maintains an intact crown in some portions of the stand. Maintains critical habitat (eg. cavity trees, downed woody debris) for many wildlife species. Coppice: management form which relies on vegetative reproduction (stump or root suckers) Tree to be coppiced, cut close to base in winter, shoots rapidly regrow from stool the following spring, coppice ready for harvest between 7-20 years. Coppice w/standards: coppiced stands maintained through multiple cutting cycles. Addresses need for small wood and multiple uses simultaneously (e. g. fuelwoord, structural timber, seeds for livestock) With few regional examples, coppice with standards is no longer in use except:
