  1. 1)According to the Köppen-Geiger climate classification [21]. This data will in most cases not be provided by the primary studies but will be extracted elsewhere.
  2. 2)May include, e.g., specific substrates, soil amendments, configuration of multiple wetlands, or other means of enhancing the outcome.
