Peatlands throughout western Canada have been bisected by a network of seismic lines associated with oil and gas exploration operations. Creation of these features involves removal of upper-story vegetation, and often results in peat compaction, increases in soil moisture, and reductions in microtopographic variability. As a result of the loss of dry microsites, natural tree regeneration tends to be limited following seismic line abandonment. This results in maintenance of open sightlines and travel corridors for predators, directly contributing to declines in woodland caribou populations. As such, several mounding treatments have been developed for use on seismic lines, with the goal of creating elevated, dry microsites to promote tree survival and growth. However, it has remained unclear whether these mounds will be resilient to natural disturbances such as wildland fire. Accordingly, the smouldering potentials of five mounding treatments (variations of the inverted inline, upright inline, and hummock transfer techniques) applied in three peatlands (representing a continuum from poor fen to rich fen) were assessed using an existing peat smouldering model developed for undisturbed peatlands. Early results indicate the importance of mound water retention and moisture content in dictating resilience to combustion. In turn, these parameters were determined by regional climatic context and the species composition of moss communities on mound surfaces. These findings provide a first insight into the efficacy of mounding as a viable technique for long-term seismic line restoration in peatlands, particularly in the face of predicted increases in the frequency and severity of wildland fires.
