Evenness — Science definition
Defined in 3 courses:
- How individuals are spread among the species; 8,1,1 and 4,3,3 have the same richness and abundance and very different evenness. (Life Science & Scientific Inquiry)
- How equally abundance is distributed across sampled species. (Life Science: Biology)
- How evenly individuals are distributed across species. (Physics & Environmental Science)

In use
Evenness is how the individuals are distributed among the species, and that is the one that separates the two woods: the second is even, the first is dominated by one species.
Biodiversity, Variation & Ecosystem Resilience
Species richness counts species observed; evenness describes how individuals are distributed among them.
Biodiversity Evidence & Conservation Design
Richness counts species; evenness describes how individuals are distributed among them.
