What is Biodiversity?
Biodiversity describes the overall biological variety of an area in reference to:
Ecosystem diversity - the different types of habitats present (for example, woodland, meadow, or river).
Species diversity - the number of different species found in the area.
Species abundance - how many individuals there are of each species.
Species distribution - how those species are spread across the area.
Genetic variation - the differences in genes within populations of the same species.
