#' Forest Functions Dataset (functions)
#'
#' @description
#' A dataset containing 11 ecosystem functions measured across the FunDivEUROPE Exploratory Platform. This dataset represents the core ecosystem functions selected for multifunctionality analysis, focusing on variables that represent stocks of energy or matter, or process rates showing the transfer of these materials between ecosystem compartments.

#' @format A data frame with 209 rows and 11 columns:
#' \describe{

#'   \item{wood_decomposition}{Decomposition rate of wooden materials}
#'   \item{litter_decomposition_all}{Decomposition rate of leaf litter}
#'   \item{total_soil_C}{Total soil carbon stocks}
