  1. Percentages reported for each cover type is their relative cover across the sector based on vegetation survey plot classifications.
  2. UNR unrestored, RP1 1 year after rewetting and profiling, R1 1 year after rewetting, R10 10 years after rewetting, REF reference site.
  3. A positive water table level indicates the water is above the peat surface.
