Habitat restoration is accomplished through management, protection, and reestablishment of plants by returning abiotic factors (e.g., soil chemistry, water content, disturbance) and biotic factors (e.g., species composition, interactions among species) to historical levels. Properly restored ecosystems demonstrate the historical species diversity of the area instead of one species in monoculture. Reestablishing plants provides a food source for animals and thus helps restore animal populations.
Habitat restoration projects vary greatly in scale, ranging from small urban restorations aiming to restore patches of native plant species through landscape-scale projects that aim to counteract the impacts of habitat fragmentation by increasing the amount and connectivity of habitat over broad areas. In all cases, however, the level of success achieved will depend on a careful consideration and clear statement of the project’s goals. Goals are derived from a complex mix of ecological, social, historical, and philosophical viewpoints.
