Page 2The correct answer was given: Brain clearcutting reproduces a new even-aged stand by completely removing the mature stand. clearcutting as a silvicultural treatment has several characteristics: it causes a sudden environmental change it removes the seed source from the regeneration area the configuration of the clearcut may affect seed dispersal it begins a new rotation it will eliminate some pests that require forest cover overall, it temporarily removes the forest cover, transforming the forest community and environment. clearcutting followed by artificial (seeded or planted) regeneration has several advantages: we can avoid delay in restocking the site we can introduce a selected species, seed source, and genotype we can control arrangement and spacing we can achieve uniformity in the new stand we can overcome the problems associated with securing sufficient natural regeneration. the shelterwood method involves the removal of most of the mature stand at the end of the rotation, but a portion of the mature stand is left standing. the shelterwood method serves three basic purposes: to prepare the stand for production of abundant seed to modify the environment in a way that promotes germination and survival of the selected species to build up the amount and size of advance regeneration to ensure the prompt restocking of the new stand following overstory removal. the shelterwood method involves a sequence of 3 cuttings: preparatory cuttings: make the seed trees more vigorous and set the stage for regeneration. see our thinning page for more information. establishment/seed cuttings: open up enough vacant growing space to allow establishment of the new regeneration. removal cuttings: uncover the new crop to allow it to fill the growing space. the residual trees in the shelterwood must: be sturdy and windfirm be able to survive exposure flower and reproduce seed be the best trees of the mature stand keep in mind that the shelter trees must not occupy the entire site. a void must be created in order to make room for the new regeneration. the amount of shelter to leave will depend on the following factors: species characteristics (seeding and shelter requirements) the number of cuttings in the cutting sequence (1, 2, or 3) landowner objectives the size of the area to be regenerated the final removal harvest level required to be profitable the shelter must be removed before it impedes the growth of the new stand or threatens its survival.
