Slowly but surely, word is leaking out: the Western Hudson Bay polar bear population is stable at ~1000 bears, confirming the good news contained in maps posted on the Environment Canada website a few months ago (discussed by me here and here). Environment Canada has apparently been giving presentations in local Western Hudson Bay communities relaying their decision.

Yesterday, a press release was issued by one of the official Inuit organizations in Nunavut announcing the new official status of the Western Hudson Bay polar bear population.
Inuit residents of Cambridge Bay in the Central Canadian Arctic are resisting requests by the Nunavut Government to tranquilize, collar and tag polar bears to assist in their population survey.

I came across a story in the news yesterday about the discovery of an archaeological site in northeastern Manitoba that brings to mind a post I wrote back in November 2012 on the geological and archaeological history of Hudson Bay.
As I noted then, most of the archaeological sites found on or near the coast of Hudson Bay are about 1,000 years old or less – and this new site fits that pattern perfectly.
A news report at the CBC (June 30, 2014) carried this description of the find, at a site called Hubbard Point, which sounds like it could yield polar bear remains: Continue reading

As I outlined earlier this week, Canadian Inuit objected so strenuously to routine mark-recapture methods used by polar bear biologists during the early days of a Foxe Basin population study in 2008 that the work was abandoned and an aerial survey done instead.
In this post, I’ll examine how the polar bear biologists involved reacted to that crisis, which they called a “control of research” issue.
In a published version of a conference paper, co-authored by two of the original investigators of the Foxe Basin mark-recapture study, Lily Peacock and Andrew Derocher (Peacock et al. 2011:374), had this to say:
“Control of research is a developing source of conflict. In recent years, some permits for management-oriented research on polar bears were denied by the Government of Nunavut, local hunting and trapping organizations in the Northwest Territories, and by Makivik Corporation in Quebec. Furthermore, in a 2009 resolution, Inuit Tapiriit Kanatami opposed the capture of polar bears throughout Canada (available by request from http://www.itk.ca), even though the application of physical marks is one of the most effective methods of population estimation. Co-management is particularly difficult in Nunavut because of the large number of subpopulations (12), which makes it difficult to fund and conduct research.” [my bold]
They raised an interesting point – since the Government of Nunavut has the power to insist biologists do more than reiterate that their way of counting bears is the only acceptable way, and because the government can deny permits to projects that don’t measure up, it can lock out traditional polar bear research for virtually all of Canada (the vast majority of Canada’s 13 subpopulations are in Nunavut, see Fig. 1), especially since aboriginal organizations in the Northwest Territories and Quebec have followed Nunavut’s lead.

That means if polar bear researchers can’t find a way to make their research mesh with Inuit concerns, they’ll be out of work in Canada. Let’s take a look at their approach and see how well it worked for them — explaining in part the new prominence of aerial surveys for population assessments. Continue reading

This follow-up to my last post has some new information about drug residues remaining in polar bear meat after the animals have been tranquilized.

While researching the population status of Foxe Basin polar bears I came across an issue that seems to have garnered relatively little attention outside the polar bear community – Inuit objections to the handling of polar bears during mark-recapture surveys and the effect of this on polar bear research in Canada.
Foxe Basin is a large polar bear subpopulation region that encompasses the northern portion Hudson Bay into the area west of Baffin Island, see map below (courtesy IUCN Polar Bear Specialist Group).
Mark-recapture research methods routinely used by polar bear biologists became especially contentious in Foxe Basin during a population study initiated in 2007/2008, with Inuit residents voicing objections and biologists defending its practice. The following year, the mark-recapture effort was halted and an aerial survey took its place.
The aerial survey has been completed and a report on it was released in 2012 (Stapleton et al. 2012; see previous post for results) but we’ve heard very little about what happened to that mark-recapture study and why the Government of Nunavut pulled the plug on it. I plan to change that with the next couple of posts.
I’m not claiming to understand the nuances of the story because I’m only going by available documents. However, I think it’s important to shine some light on this issue since it has clearly changed the shape of polar bear research in Canada.
