Getting Started: An Introduction to Forest Management Planning
{"Image DocumentName": "Getting Started: An Introduction to Forest Management Planning", "Image ImageDescription": "The clearcut system is commonly used in Ontario\u2019s boreal forest. Most boreal tree species, such as black spruce, jack pine, aspen, and birch, are adapted to these types of natural disturbances and germinate and grow best in full sunlight. As a result, they often form natural, pure stands of trees of the same age. Forest Management Guide for Natural Disturbance Pattern Emulation (OMNR, 2002) requires that large living and dead trees (approximately 25 per hectare) are to be left standing by harvesters. This residual material provides wildlife habitat, mast (food), and coarse woody debris, with which to maintain biodiversity in the forest and allow for the continuation of natural ecosystem processes % of the trees must be left as residuals. Cuts in Ontario may exceed the old size standard of 260 hectares for silvicultural or biological reasons as long as a rationale is provided in the approved forest management plan. Cut boundaries often follow natural landscape contours. As well, uncut strips may be left through larger clearcuts to provide protected animal corridors from one edge of the cut to the opposite. Regeneration in this system may be natural or artificial. Often, natural regeneration is encouraged by scheduling harvests to follow a good seed year, by orienting cuts so their long axes are at right angles to prevailing winds, or by leaving additional uncut strips, patches and individual seed trees.
