Survival of the Deepest Peatlands


2024 Canadian Geophysical Union Poster [PDF]

  • Northern peatlands are generally resilient to drought and wildfire disturbance due to ecohydrological feedbacks.
  • Most studies have been conducted in large and deep peatlands where ecohydrological feedbacks often have a moderating effect on water table depth.
  • Shallow (depth < 0.5m) peatlands are underrepresented.
  • Loss of resilience has been observed as a result of degradation or drainage, which often are accompanied with a decrease in peat thickness.

Objective: Determine the presence and relative strengths of ecohydrological feedbacks in shallow and deep northern peatlands.

Survival of the Deepest Hypothesis: Peat depth is correlated to peatland ecohydrological resilience, and that vulnerability disproportionately increases below a threshold peat depth (for a given climate and hydrogeological setting)



To refine our predictions, we are seeking input from a wider range of perspectives.
