#' BCI 50 ha plot taxonomy
#'
#' A matrix of similarities between species based on their taxonomy. If the
#' similarity is at a given level, and no higher, then this is the similarity:
#'
#' species_similarity <- 1
#' genus_similarity <- 0.75
#' family_similarity <- 0.5
#' subclass_similarity <- 0.25 # we use "order" instead of "subclass"
