Measuring Biodiversity
. Biodiversity is important as it reflects the environmental health of a species, region, or habitat. BIODIVERSITY - DEFINITION The number and variety of plants, animals and other organisms that exist in an ecosystem is known as biodiversity It is a measure of the variety of organisms present in different ecosystems The richness of biodiversity depends on the climatic conditions and area of the region ' Biodiversity is the result of 3.5 billion years of evolution 2 We use your LinkedIn profile and activity data to personalize ads and to show you more relevant ads.

Measures of species diversity can be divided into three categories (Magurran, 1988). Biodiversity, also called biological diversity, the variety of life found in a place on Earth or, often, the total variety of life on Earth.
