Leopold ecological restoration ideas were greatly influenced by Thoreau idea.
Indeed, Leopold was an active participant in the ecological restoration as evidenced by his activities. By 1935, prior to the acquisition of the farm, the number of nesting pairs of sandhill cranes in Wisconsin were 25. This was one of his major concerns and he thereby corresponded with people in Wisconsin that have knowledge of sandhill cranes. The collective effort of Leopold and his colleague has yielded positive fruits as there are 12,000 sandhill cranes in Wisconsin as of today.
Prior to Leopold acquisition of the farm, there were no otter neither was there wolves spotted on the farmland. These extirpated wildlife has made a comeback. Lutra Canadensis has reappeared and there are otter in the otter pond. Likewise is the presence of radio-collared wolves noticed in the farmland.
Leopold benefited from his ecological restoration of an insignificant farmland. For instance, from an insignificant tree oak Leopold got firewood, exercise, family teamwork, and a history lesson. Leopold also preserved the economically worthless Draba by avoiding the planting of pines in area that favors the growth of these plants. The planting of 48,000 pines in thirteen years, indeed, demonstrates Leopold commitment to ecological restoration.
Various groups are involved in the ecological restoration and these include the Germantown High School and the Leopold Foundation that collaborates with International Crane Foundation. In fact, the Germantown High School has successfully raised $15,000 to fund ecological restoration in addition to restoring the prairie by planting seeds collected from the Leopold farmland. The International Crane Foundation works towards the preservation of the world’s fifteen species of crane and towards the protection of crane habitat.
Leopold through his writing and experiment at the abandoned farmland has built a legacy for himself. In the
