Silvicultural Systems in Western Larch Forests
View through CrossRef
Abstract
Western larch (Larix occidental is Nutt.), one of the most valuable and attractive species in the northern Rocky Mountains, grows in association with most native conifers in this region. Larch is extremely intolerant of shade and requires nearly full sunlight and well distributed and
exposed mineral soil for good seedling establishment and growth. Because of these silvical requirements, larch stands are usually harvested and regenerated by clearcutting, seed tree, or shelterwood systems. Seedbed preparation is normally accomplished by scarification or prescribed burning.
However, due to multiple use considerations, these silvicultural practices should be modified on some areas. This paper discusses some of the effects of various silvicultural systems in western larch stands.
