Biodiversity habitat index formula
WebThe Diversity Index is a measure of the biodiversity of a group of organisms in an area. The value of the Diversity Index will vary between 0 (no diversity) and 1 (high diversity). Values around 0.5 indicate that an area is relatively diverse. A healthy forest might have a Diversity Index of 0.7 or 0.8 while an agricultural field might have a ... WebA simple biodiversity index is calculated as follows: number of species in the area ÷ total number of individuals in the area = biodiversity index. For example, a 4 X 4 meter square area in a carrot patch has 300 carrot …
