As undeveloped lands are converted to residential uses, natural corridors should be created to preserve natural systems. There are two kinds of natural corridors. One is a large reserve on the edge of the neighborhood and the other is a narrow section that penetrates into the neighborhood. Wider corridors should be implemented into any residential plan, with precautions for wildlife such as identified animal crossings. Ideally speaking, natural corridors will extend beyond a single neighborhood and connect to other corridors, creating larger habitats for wildlife. The visibility of such greenspace often proves to be an economic benefit to landowners.
