  1. a Peatland sites with only one peat core sampled were excluded from the estimation because those depths could be biased and likely represent the deepest center of peatland sites [24]
  2. b Average depth of peat cores from a site; the depth of each peat core was not reported in the SEO peatland survey report unless there was only one core from the site
