2.3. Process to estimate diversity with forestry surveys
Our method is based on the simulation of species occurrence
tables. Using a Monte-Carlo scheme we simulate different types
of determination errors in forestry surveys, taking into account
the taxonomic accuracy of common names. Fig. 2 summarizes
the computation process in four steps: (1) formatting nomenclature
used in forestry surveys to define the expected taxonomic
accuracy of common names, (2) computing taxonomic reliability
of the common names taking into account the expected taxonomic
accuracy, (3) propagating uncertainty in diversity estimates
through simulated communities and (4) computing different diversity
indices (i.e., alpha and beta entropy, Fisher-alpha and Sørensen
index) and validating the estimates with botanical data.
