The Shannon Variety Index, also known as the Shannon-Wiener Index, is a tool used to assess the species diversity within a community.
Ecology frequently uses the Shannon diversity index, also known as the Shannon-Wiener diversity index. It calculates species diversity using Claude Shannon's entropy formula. The index considers both the relative abundance of each species and the number of species present in an environment (evenness).
It is determined by adding the proportions of the total number of individuals, the number of each species, and the percentage times the natural log of the proportion for each species.
