simpson's diversity index
The Simpson's Diversity Index is a way to measure the diversity in any given ecosystem. It takes into account two major factors, evenness and richness. A simple equation is used to measure the Simpson's Index (D)
D=N(N-1)/(Sum of n)(n-1)
D=diversity index
N=total number of organisms of all species found
n=number of individuals of a particular species
A high D value indicates a stable system, and a low D the opposite. A low D could be caused by pollution or recent changes.

diversity in agriculture
It is essential to keep diversity in an agricultural ecosystem for better yields and a more stable system. We took a field trip to a field to see hedge rows in place. These rows aided in attracting pollinators and keeping the diversity up with both plants and insects.
