The tropical weed Miconia is a non-native species that has taken over much of Tahitis native vegetation. The hot, dry climate of the Cretaceous period changed very quickly, most likely because of an asteroid striking the Earth. Such species may arrive in new areas through natural migration, but they are often introduced by the activities of other species. In the 1940s, their populations were nearly extinct due to hunting and poaching threats. -Keystone species are those with major effects on ecological functions and whose elimination would affect many other members of the biological community.

That means domesticated plants may lose an important source of traits that help them overcome new threats.The Red ListThe International Union for Conservation of Nature (IUCN) keeps a Red List of Threatened Species. The Red List defines the severity and specific causes of a species threat of extinction. For example, most of the food crops grown in the United States, including popular varieties of wheat, tomatoes, and rice, are not native to the region. Saving this habitat also benefits other species, Flagship species are especially interesting or attractive organisms to which people react emotionally. Endangered and threatened species need our help. The world has around 1 million named insect species, and around 5,400 species of land mammals. Habitat loss is the leading known cause of population decline.A species is also classified as vulnerable if its population has declined at least 30 percent and the cause of the decline is not known. Probably Vulnerable but definitely NOT "near threatened" One way to try to protect species is to focus on areas with high species diversity. Indigenous species have evolved without defenses against predators or competitors. Dinosaurs became endangered, then extinct.Human activity can also contribute to a loss of habitat.
