In situ conservation is the most important method of conserving wildlife as the wildlife species are still living where the conditions for survival are appropriate and the entire community of species is present together
Establishing a protected area or nature reserve makes it easier to prevent damaging influences within the area itself but it does not protect it from damaging external influences such as air pollution
General approaches to habitat conservation:
land ownership
designated protected areas
habitat creation and management
Land ownership -
many wildlife conservation organisations purchase areas to protect species that already live there or will do so once the conditions have been changed so they are suitable
individual landowners may also make management decisions for the benefit of wildlife
