Last week, with more than a little help from our friends, we were able to restore a big section of marmot habitat at Mt Hooper. We need to thank Cam William-Johnston and Matt Kelly from the Port Alberni Thunderbirds Fire Fighting Unit, and Trudy Chatwin, retired Species-at-Risk biologist, for volunteering their time to work in this challenging terrain! Thank you also to TimberWest for facilitating the work, and Environment and Climate Change Canada for funding it!
This crew was working to restore open sightlines by removing brush and low branches from the marmot’s habitat. Marmots rely on these open sightlines to spot and avoid predators, and this restoration work will help keep the delicate balance between predators and prey intact.
The crew removed “stalking cover” – shrubs and low branches that predators such as wolves and cougars use to sneak up on marmots. This should happen naturally as avalanches sweep this material out the marmot colony, but extremely low snowpacks for several years have resulted in a lot less avalanche energy. In turn, we have seen an increase in the stalking cover. When we mapped where marmots were predated at Mt Hooper, it almost always occurred where this stalking cover had grow up.
