The study of island biogeography has been used to help wildlife managers in national parks and wildlife refuges assess and predict the biodiversity of the areas they see. How are national parks or wildlife refuges compared to islands?

Since islands are isolated from continents they do not experience immigration (depending on their distance to a mainland or other island) as a national park or wildlife refuge on the mainland would.
