Restoration is a large component in creating and maintaining wildlife refuges. The Hakalau Forest National Wildlife Refuge, located in Hawaii, is a current example of an area must be restored and formed back into the vital ecosystem that it once was. The refuge was officially established to sustain many species such as birds, hoary bats, and native vegetation (Conrow, 2008, p. 31-37). Many of these species are on the Endangered Species List or are suggested to be on the list soon. Most of the islands in Hawaii have been severely damaged by overgrazing livestock and invasive species introduction, specifically, the Acacia tree. Not only plagued with invasive species but, also, the Hakalau Forest is 33,000 acres in size with ranging elevation (Conrow, 2008, p. 31-37). The maintenance of the forest and survival of endangered species depends on careful analysis and remediation in order for native and migratory birds for successful reintroduction in…show more content… First cattle herds and pigs are removed in order to release the land of “grazing pressure” (Conrow, 2008, p. 31-37). Many of the animals raised in this manner were non-native and overpopulated. 14,000 acres are then divided into eight separate plots and over time are cleared of grazing animals and non-native plants (Conrow, 2008, p. 31-37). By dividing the land in sections ranchers had time to remove the livestock and the proper focus and remediation could take place on smaller scales. The foresters and volunteers then observed the strength of the native seedbanks still left on the ground. As the native plants emerge, teams of workers spent days continuously removing of many invasive species such as, but, not limited to: blackberry, gorse, and holly (Conrow, 2008, p. 31-37). At the lower elevations, most of what was necessary was to clear the land of overpopulated or non-native species to allow the native Koa trees to
