Forest fire that burns only undergrowth and leaf litter on the forest floor. See controlled burning. Compare crown fire, ground fire.
Subject:
strip cutting
Variation of clear-cutting in which a strip of trees is clear-cut along the contour of the land, with the corridor narrow enough to allow natural regeneration within a few years. After regeneration, another strip is cut above the first, and so on. Compare clear-cutting, seed-tree cutting, selective cutting, shelterwood cutting.
Subject:
Shelterwood cutting
Removal of mature, marketable trees in an area in a series of partial cuttings to allow regeneration of a new stand under the partial shade of older trees, which are later removed. Typically, this is done by making two or three cuts over a decade. Compare clear-cutting, seed-tree cutting, selective cutting, strip cutting.
Subject:
selective cutting
Cutting of intermediate-aged, mature, or diseased trees in an uneven-aged forest stand, either singly or in small groups. This encourages the growth of younger trees and maintains an uneven-aged stand. Compare clear-cutting, seed-tree cutting, shelterwood cutting, strip cutting.
Subject:
seed-tree cutting
Removal of nearly all trees on a site in one cutting, with a few seed-producing trees left uniformly distributed to regenerate the forest. Compare clear-cutting, selective cutting, shelterwood cutting, strip cutting.
Subject:
second-growth forest
Stands of trees resulting from secondary ecological succession. Compare old-growth forest, tree plantation.
Subject:
Restoration ecology
Research and scientific study devoted to restoring, repairing, and reconstructing damaged ecosystems.
Subject:
reforestation
Renewal of trees and other types of vegetation on land where trees have been removed; can be done naturally by seeds from nearby trees or artificially by planting seeds or seedlings.
