Table 2 Estimated peat depths for SEO peatlands

From: Potential carbon loss associated with post-settlement wetland conversion in southern Ontario, Canada

  Southeastern Ontario peatlands survey Estimated peat depth (m), mean [SD]
Peat depths recorded sites (cores per site)a Total peat cores Peat depth rangeb (m)
Conifer swamp 23 (4–140) 556 0.7–5.0 2.2 [1.1]
Mixed swamp 25 (3–148) 799 0.2–3.7 1.7 [0.8]
Deciduous swamp 29 (3–161) 663 0.4–4.3 1.3 [1.0]
Shrub swamp 32 (3–91) 415 0.3–6.0 1.7 [1.3]
Fen 20 (2–37) 180 0.9–4.4 2.4 [1.0]
Bog 13 (2–36) 159 1.9–3.9 2.9 [0.8]
Marsh 19 (2–40) 138 0.4–3.5 1.5 [0.9]
(All sites) 161 (2–161) 2910 0.2–6.0 1.9 [1.2]
  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
