Indices of species diversity are used which may give more or less weight species that are dominantly found in the landscape. All you do is count of the number of subspecies found in a community (e.g., the number of the subspecies found in the Meadow Fields zone). Estimates are that there are at least 10 million species. Biodiversity indicators help us measure and monitor a) pressures or threats, such as trends in land and water use, habitat loss or invasive species, b) the state of species and ecosystems, such as the health of species or integrity of ecosystems, c) the conservation response, such as the protection of important biodiversity areas, and/or d) benefits to people, such as the ecosystem services that freshwater provides. How much is significant ?
