Default What is this (Thar Peak)

I came across a rather unusual looking thing near the Pipeline Road on the way up to Thar Peak:



Anyone know what this is? Note that there is a hard-to-see cable running across the top between two trees (about 3 meters long).

Oh, and for scale, those white bars are probably about 25 cm (< 1') long.

It's actually an apparatus used for research on mustelids (weasel family), called a run-post, I believe. They typically hang some sort of bait in front of it (beef bone, etc.) so that the animal will run along the base and then put its forelimbs on the metal bar while it reaches up for the bait. The researchers will usually set up a trail cam in front of it to grab a pic of the animal for counts and other observations, as the coat colors on the chest are often unique to each animal (in wolverines anyways). They also occasionally have multiple screw heads with clothes pins attached along each vertical white bar (none present on the one pictured); once the animal brushes against them, the clothes pins release and grab bits of hair from the animal, which can be used for genetics and other various testing (cortisol, toxin residues, etc.). I realise this sounds super made-up, haha. Only reason I happen to know about this is that I am a vet and was recently working on a masters project on mustelid health and disease and happened to go to a conference where they showed us pictures of these things in action and took us into the field to see one set-up. I'll see if I can dig up the picture I took of the one we saw. The one pictured seems like it may be too small for a wolverine, and I don't know if we have any wolverines along the Coquihalla, but looks like it may be the right size for martens or fishers. Hope that helps.

Fascinating, perhaps the clothes pins were removed for the winter.

Fascinating, thanks much for the detail explanation Treord8.

My first thought when I saw, it was part of a gate apparatus ...

Hiking is what keeps you young of mind and heart. When the going gets tough, the tough get going..............

Couldn't find my pic of the same set-up yet, I think it's on my external hard drive somewhere, but here are a few other similar hair-snag traps attached to trees.

Just saw a feature in a recent BC Outdoors Magazine on a guy I met doing research on wolverines. It had some cool pics of these sorts of apparatus if anybody is interested.

Wilderness is not a luxury but necessity of the human spirit.
