We Are Trying To Figure Out…
How diverse is our pond fish population?
How has the biodiversity changed over the
last few years? What can the hidden pond's biodiversity tell
us about the pond's health?

Biodiversity can be calculated using
an equation called Simpson's DiversityIndex (SDI).
Here is one such example
D = (n / N)2
Where n is the total number of
organisms of a particular species andN is the total number of organisms of
all species. D is the value of diversity
