Survival of the Deepest Peatlands
2024 Canadian Geophysical Union Poster [PDF]
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.
Please complete this survey when time permits.
- 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.
