Costa Rica has created several mega-reserves. In the accompanying figure, green areas are protected natural parklands and yellow areas are the surrounding buffer zones. Discuss the value of the reserves and how they could be linked.

In the mid-1970s, Costa Rica established a system of nature reserves and national parks. By 2014, this system included more than 27% of its land-6% of it reserved for indigenous peoples. Costa Rica has increased its beneficial environmental impact by devoting a larger proportion of its land to biodiversity conservation than any other country-an example of the biodiversity. Establishing protected habitat corridors between isolated reserves can benefit more species and allow migration by vertebrates that need large ranges. Corridors will also allow some species to move to areas that are more favorable if climate change alters their existing areas.
