The sum of coverages of all the specimens in the plot is the total coverage per plot (in %).Diversity indicesDiversity is a concept that encompasses the number of species and their relative abundance.The Shannon Index (D) and the Simpson Index (S) were estimated for this sampling protocol.Both are calculated determining the proportion of individuals for each species contributing to the total sample (Pi) (Begon et al., 1997).The formulae are as follows:
