Focusing conservation resources and actions within a relatively small area can therefore help to conserve an important component of the earth’s terrestrial biodiversity. A ‘species/area’ curve of the numbers of restricted-range landbirds and the area that they occupy shows that, historically, the 2,451 restricted.
