With this option diversity indices (Richness, Shannon, Evenness and Simpson) can be calculated for each plot observation in a dataset.
Note the the analysis is only possible on selected plot observations.
Merge vegetation layers: with this option checked species are only counted once. Cover percentages of a species occurring in different strata are added up in the following way:
coverAB = coverA + (100 - cover A) * coverB * 0.01.
In case the procedure is applied to a single dataset the fields that hold the calculated diversity values will be automatically added to the profile. By default, the new information will be displayed at the right end of the header data table. Via the Profile management the properties of the new fields can be changed.
