The answer is:
Community Diversity.
Reason Why: Here is an example, say you have 2 communities, community 1 is A, and community 2 is B, Communities A and B contain 5 tree species, However because community B has greater species evenness it has greater species diversity.
Community A is dominated by one of its 5 species and so has lower species diversity than.....community B, which has the same 5 species but in equal proportion.
Richness- Number of Species
Evenness-Relative abundance.
