Working with United States Fish and Wildlife Service in the Cabinet-Yaak ecosystem – one of six grizzly bear recovery zones in the lower 48 states. Identifying individual grizzly bears within the total population (approximately 45 bears) using non-invasive methods: collecting hair samples (arising from natural bear behaviour), to enable identification of individuals through genetic analysis. Bears rub against trees so we go collect the hair from those on a 2 week cycle. We also build hair corrals – barbed wire rings around a group of trees – within which is a pile of wood soaked in blood – attracting the bears across the wire so they leave hair behind. Hair samples are sent to a lab in Nelson, Canada for DNA analysis to identify every single individual bear.


Cabinet-Yaak Ecosystem Grizzly Bear Monitoring and Research – Field Diary 2015
Featuring bear hair collection activities conducted in the Yaak River Drainage and Cabinet Mountains of North West Montana.
“Here is my field diary from 2015. You can see how much hiking was required, to achieve the hair samples. There are also records of all major critter sign (scats and tracks) and then mentions of large mammal sightings – which are relatively few – they tend to run away at the sound of human beings. Also notes of various adventures and fun escapades along the way. “

GPS collar retrieval from dead grizzly bear. (I’m not allowed to show any images of the carcass). We inspect what is left. The bear died around 2 to 4 weeks ago. All that is left is her fur and the skeleton; there is no flesh left whatsoever, her carcass has been picked clean by the critters. We know this bear was young and healthy last autumn and we are confused about how she might have died. Then we find a puncture hole through her nose: it might be that she was attacked by a mountain lion. Alas, this is very sad. However we stand below the waterfall and green shrubbery and reflect that she had found a beautiful spot for her last resting place.

3rd July Windy Pass. Radio Collar Retrieval from Grizzly Bear (Signal on Mort) With Kirstie Yeager and Matt Miller
8 miles in and out with frightful bushwhacking. Flat. Hot. We cycle up a closed road and have to drag our bikes through alder tree hell. After 2 hours we ditch the bikes and then bushwhack, getting scratched to shreds. I am bleeding from it feels like 100 lacerations. I am being eaten alive by mosquitoes and flies which seem impervious to 100% deet. I am hot and parched and my water has to be rationed. After 2 more hours we arrive at the spot that Wayne has marked on the map. Kirstie gets the radio equipment out so that we can use telemetry to find the radio / gps collar. Then…..Kirstie announces she has left the radio receiver at the truck…. We will be unable to listen for the collar…..! We are unable to find it on the forest floor. We consider that we have to go home and try again another day. But I lack the strength to stand the bushwhacking anymore. I collapse on the forest floor, gibbering with madness.

I know it is disappointing – I am not allowed to show you the photos of the bear. To compensate, here is a daunting picture of Kirstie’s alf-alfa . You can only imagine that anyone like her who has the enduring persistence to grow this stuff, also has the courage and composure to dart an angry grizzly.

Yes, it is the end of the season and this is the first bear picture i get – and it’s not even that good. Until mid July i only carried my phone camera with me, because my wildlife camera weighs about 4kg and is not helpful whilst i’m doing hair collection work. From mid July I realised I had no decent bear photos, so decided to start carrying the wildlife camera, but even then every bear I encountered ran away too quick, so it was only at the end of August I finally got a roughly decent picture….
