Forest Management :: essays research papers
Forest focusing is the maintaining and management of non only thetrees in the plant, but the streams, habitat, watersheds, and even thedecaying trees or logs on the tone floor. Managing our tones is not onlyimportant to the wildlife, but to our future economy and office of life. We needto continue to save the Oregon forests and help the ecosystems within thembecause military personnel beings ar also part of the ecosystem.By using forest management, it displace help certain species of wildlife. Some species of birds, such as the pileated woodpecker, which need big(p)snags to build nest cavities(7). But the worst possible approach to maintaininga wide mixture of species would be to manage every acre of the forest the selfsame(prenominal) way. Any change in forest habitat creates &8220winners and &8220losers. Asforests go through natural cycles of growth, death and regeneration, speciesmay inhabit or be absent from a given area partly in answer to naturalchanges in the struc ture of trees and other forest vegetation(4). The sameoccurs when forest stands are managed by humans.Unless future credible research indicates otherwise, effort should bemade to manage a wide range of forest structures. Maintaining diversity wouldbe best served by using a broader range of management tools. Those wouldinclude harvesting on federal official area - not simply thinning - and increasing thecommitment to old-growth attributes on private forest land throughtechniques such as retaining large trees and snags. As long as federal landsare substantially committed to providing late successional habitat, privateforest land can be substantially committed to younger, intensively managedstands, provided exact habitat characteristics are available.The federal lands make up more than 50% to 60% of the forests inOregon(3). Because timber harvest in now dramatically reduced on federallands, those lands represent a sizable, well distributed share of both old-growthforests and forest s that could become old-growth, providing habitat to thosespecies associated with forests with old-growth characteristics. While a large raft of federal land is committed to sustaining species that needold-growth, the difficult question remains, how frequently is enough? Leaving theseforests completely unharvested invites unacceptable, large-scale insectinfestations and catastrophic fires(6).Because federal lands comprise nearly 50 to 60 percent of Oregon&8217sforests, practices on these lands have a major impact on forest-dwellingvertebrates(2). These lands are well distributed throughout the state. Private land will power accounts for approximately 40 percent of the statesforests(5). Of this private ownership, over half is in industrial ownership andthe rest is held mostly by small woodland owners(7).Since 1992 harvesting on federal lands has dropped sharply.
