The flora and fauna of any given region is usually explained in biological terms to include the genus and species of plant and animal life, their preferred growing or breeding habits, and their connection to one another in the environment as well. In addition to geographical groupings, environment also helps further classifications of flora and fauna. For example, aquatic flora and fauna of a region refers to the plant and animal life found in the waters in or surrounding a geographic region.
Biologists and environmentalists study flora and fauna for a number of reasons. Preservation and conservation as well as gaining new biological understandings are just a few reasons why flora and fauna are important to researchers. Several organizations, including Fauna and Flora International (FFI), work together to use their research and findings to further policy on conservation and preservation as well as biodiversity.
