Bait and scent lure is applied to a tree. A DNA collecting gun brush belt is attached to the tree below
the attractant and a camera is placed on an adjacent tree to capture visitors to the attractant.
Figure 2 Short-term camera trap set up. A gun brush belt is attached to the tree and bait is secured above this so that
animals seeking to access it must pass the gun brushes. Camera is set up to capture the base of the tree as well as the bait to
ensure animals that visit the station but do not climb the tree are documented.
Long term installations: Run poles
Run poles are established and maintained following the protocols developed by Aubrey and Raley
(2013) which field teams are provided with and trained in.
Run poles involve construction of a horizontal beam ("run pole") out from a tree which a wolverine
will walk out on to investigate an attractant hung above the end of it. A camera is set to photograph
the animal at the end of the run pole when the animal is facing the camera in hopes of capturing an
image of its chest blaze. A hair snagging device is attached to the tree below the run pole or on the
pole itself. A second camera is attached to another tree which photographs the ground below the
run pole and attractant to capture images of any animals that visit the set but do not go out on the
run pole.
