Simpson’s Diversity index is a value that represents the species diversity (a type of biodiversity) in a location, generally with the purpose of comparing it to another location, or to compare the changes in a single location over time.

This video outlines how to use Simpson’s reciprocal index (one of several variations on the same index).

Ethan Soloviev, HowGood’s Chief Innovation Officer, and Arthur Gillett, HowGood’s Director of Research, discuss the quinoa problem, why big brands are finally addressing biodiversity, and the opportunities presented by emerging measurement approaches.

Did you know what’s living in your backyard or favorite nature spot? Scientists often study all the living things (and non-living things!) in a small area or ecosystem to understand the biodiversity and health of a much bigger area.

Using just a hula hoop, a pencil and paper, and the power of observation, JD shows us how to observe the biodiversity of a small area.

– determine diversity of species using measures such as species richness, evenness (relative species abundance), percentage cover, percentage frequency and Simpson’s diversity index
– Guidance: Diversity indices and measurements should be supported through fieldwork and based on classification. Measures of biodiversity, i.e. species richness (S) and Simpson’s diversity index (D) should be used where applicable
– Guidance: The formula used to quantify biodiversity of a habitat is Simpson’s diversity index (SDI), shown as:
