Seismic Line Successional Recovery: Implications for Animal Movement and Weed Invasion in the Boreal Forest

Seismic lines occupy a proportionally small area of landbase, but may have disproportionately large ecological impacts (e.g. altered successional patterns, altered movement/dispersal patterns for both animals and invasive plants, altered predator-prey dynamics).  Accordingly, the objectives of this proposed study are three-fold:

  1. evaluate successional recovery and relative invasibility of seismic lines to non-native and/or weedy plant propagation as a function of seismic line type (conventional vs. low-impact), age, and ecosystem/habitat type. Addresses Gap 10, 11, and 15 of the AUPRF Issue Statement (Ecological).
  2. examine relative use of seismic lines as game trails, and determine if this use is affected by seismic line type (conventional vs. low-impact), age, and/or ecosystem/habitat type. Addresses Gap 10, 11, and 15 of the AUPRF Issue Statement (Ecological).
  3. clarify importance of anthropogenic linear features as travel corridors for wolves and advise the energy sector about the efficacy of implementing features, such as LIS, to limit wolf access to caribou habitat. Addresses Gap 15, and indirectly addresses Gap 7 of the AUPRF Issue Statement (Ecological).
