An even-aged method of logging in which the timber is removed in two or more stages, with large trees of 30-40 square feet basal area per acre providing seed for natural regeneration, shelter for developing seedlings, and a fairly visually continuous canopy.
The cutting of most trees, leaving those needed to produce sufficient shade to protect young seedlings growing beneath them.
A silvicultural cutting method in which, in order to provide a source of seed and/or protection for regeneration, the old crop (the shelterwood) is removed in two or more successive shelterwood cuttings. An even-age stand results.
an even-aged silvicultural harvest and regeneration system that gradually removes most or all trees in a series of partial cuttings, which resemble heavy thinning. Regeneration establishes under the protection of partial canopy cover.
A cutting method used in a mature stand, designed to establish a new crop under the protection of the old. Most trees are removed, except for about 6 large trees per acre. These remaining trees are then harvested in about 5 years, after seedlings are established. The end result looks like a clear-cut.
A harvesting system which involves the removal of a large volume (about 50% of wood from a stand so that the remaining trees provide seed and shelter for a new crop of trees.
A method of harvesting in which some mature trees are left standing in order to provide protection and shelter for the young regeneration
A harvest method for regenerating a site that involves the gradual removal of the residual stand in a series of partial cuts. A new forest is established before the complete removal of the parent stand.
a regeneration cut designed to stimulate reproduction by removing all overstory trees. This is achieved by a series of cuts over several years. Gradual reduction of stand density protects understory trees and provides a seed source for stand regeneration.
the cutting of most trees, leaving those needed to produce sufficient shade to produce a new age class in a moderated microenvironment
method to regenerate forests where part of the stand is left to nurture the young stand
Removal of the mature timber in a series of cuttings, which extend over a relatively short portion of the rotation, by means of which the establishment of essentially even-aged reproduction under the partial shelter of seed-trees is encouraged. (HARV SHELT)
A method of regenerating a forest whereby a portion of the stand is harvested and the rest of the stand, evenly distributed over the area, is left to protect the site and provide seed to reseed the area. After the new stand is well established, the residual trees are harvested. The method is used to regenerate species not tolerant of shading.
