The concept you are describing relates to "native species." Native species are organisms that have naturally evolved or developed in a particular region or ecosystem over long periods of time. They are well-adapted to their environment and play a crucial role in the ecosystem's balance.
In the case of alligators and crocodiles in the Florida Everglades, both are native species that thrive in the wetlands and aquatic environments of this unique ecosystem. Their presence contributes to controlling the populations of other species, helps maintain the ecological balance, and supports biodiversity within the Everglades.
Other examples of native species in specific ecosystems can include:
- Bald Eagles in North America, particularly in forested and wetland regions.
- American Bison in the North American plains.
- Redwoods in the coastal regions of California.
These species are integral to their respective habitats and are often important indicators of environmental health.
