In the United States, you can find many species of plants and animals that occur nowhere else on Earth. From the tropical rain forests of Hawaii to the deserts of Arizona, an amazing variety of organisms fill a wide range of habitats. There are about 20,000 different species of plants alone that are considered native to this country. Unfortunately, one in every five of these plants is now of some concern to conservationists. Nearly three-fourths of the rarest of these plants are found in just five areas: Hawaii, California, Florida, Texas, and Puerto Rico and the U.S. Virgin Islands.
