​Seismic lines are one of the most pervasive human disturbances in the boreal forest, with over 85 000 km of seismic lines in the west-central Alberta and Chinchaga caribou ranges. We are currently looking at field-based measurements of vegetation regrowth on seismic line, non-invasive animal use data (camera traps & tracks/scats), and attributes of the landscape from a Geographic Information System (GIS) to identify seismic lines that are attractive to alternate prey (deer, moose, and elk), and predators (bears, wolves, cougar, lynx, and canines) within caribou ranges in west-central Alberta, and the Chinchaga. Research is ongoing for this project, and preliminary results show that the use of seismic lines by alternate prey increased with early successional stands (young forests and disturbed areas such as harvest blocks and well sites). We also detected more alternate prey on seismic lines with more graminoids and less alder. For predators, our preliminary results show that bears were more likely to use seismic lines with more vegetation cover, less alder, and more signs of moose, while lynx and wolves used seismic lines with less vegetation cover. Prioritizing restoration of seismic lines based on the probability of use of seismic lines by alternate prey and predators could focus restoration efforts towards areas that will have the most benefit for caribou (i.e. reduce overlap among caribou, alternate prey, and their predators).
