Measures of Biodiversity

Species Evenness is a measurement of:

• the number of different species in a community

• Having even numbers each species is in a community or ecosystem.

• how spread out the species are in a community

• How rare the species are in a community

Species Richness is a measurement of:

• the number of different species in a community

• how close in numbers each species is in a community or ecosystem

• how spread out the species are in a community

• How rare the species are in a community
