A keystone species is a species on which the persistence of a large number of other species in the ecosystem depends. If a keystone species is extirpated from a system, the species it supported also will disappear, as will the other dependent species.
Keystone species may be top carnivores that keep prey in check, large herbivores that shape the habitat in which other species live, important plants that support particular insect species that are prey for birds, bats that disperse the seeds of plants, and many other types of organisms.
An example of a keystone predator is the sea otter, which is a keystone in the kelp forest ecosystem. Kelp forests are marine forests of seaweed that provide food and shelter for large numbers of species of fish and shellfish.
They also protect coastlines from damaging wave action. Sea otters prey on sea urchins and keep their numbers in check. If the sea otters are extirpated, large numbers of sea urchins feed heavily on the kelp forests, causing severe declines in the kelp forests and their associated species. Wherever otters have been reintroduced, kelp communities have returned.
Ironically, many fishers resent sea otters because they view them as competitors for valuable commercial fish and shellfish, such as abalone. They do not realize that without the otters, the abalone would not have kelp forest habitat.
Protecting keystone species is a priority for conservationists. Unfortunately, the keystone functions of a species may not be known until it has been extirpated and the ecosystem changes.
Keystone species may occur at any level of the ecosystem, from plants and herbivores plant eatersto carnivores meat eatersand detritivores waste eaters.
Where a keystone species has been identified, efforts to protect it also will help protect the other species in delicately balanced ecosystems.Coordinates. The United States of America (USA), commonly known as the United States (U.S.

The article provides an in-depth look at the sources of funding from hunters and how these funds are spent, from wildlife management and species recovery to the work of federal and state fish and wildlife agencies and nonprofit organizations.

Once revered as deities in Mayan and Aztec culture, jaguars possess immense grace and power. These agile hunters once lived throughout South and Central America and in the southern and central United States, but they lost habitat and were killed off to near extinction north of the U.S.-Mexico border.
Wildlife professionals throughout the United States have long struggled with a problem that will seem familiar to almost everyone-the desire to do what needs to be done and the money to accomplish the task. creating a new excise tax hindered the movement's progress.
