We collected high-resolution aerial imagery and associated ground-truthed data from four sampling blocks in two caribou ranges to assess human footprint accuracy and state of vegetation recovery.

Project Description: Beginning in 2003, moose populations were intentionally reduced by increased hunting pressure as an indirect way of reducing wolf numbers — fewer moose on the landscape means...

Boreal rivers deliver dissolved organic carbon (DOC), mercury (Hg), and its neurotoxic form, methylmercury (MeHg), from contributing landscapes to downstream waters. In northern regions, thawing...

Our goal is to improve conifer seedling survival and growth so that planted seedlings will reach the "free to grow" stage sooner. It is at this stage when the exponential growth trajectory towards...

Caribou (Rangifer tarandus (L., 1758)) play a central role in the ecology and culture of much of Canada, where they were once the most abundant cervid. Most populations are currently declining, and...

Based on declines, future developments and current recovery effects, we offer the following recommendations: 1) where recovery actions are necessary, commit to simultaneously reducing human intrusion into caribou ranges, re-storing habitat over the long term, and conducting short-term predator control, 2) carefully consider COSEWIC’s new DU structure for management and recovery actions, especially regarding translocations, 3) carry out regular surveys to monitor the condition of Northern Mountain caribou subpopulations and immediately implement preventative measures where necessary, and 4) undertake a proactive, planned approach coordinated across jurisdictions to conserve landscape processes important to caribou conservation
