Public misled about W Hudson Bay bears since November 2013

Posted on December 8, 2014 | Comments Off

Leading polar bear biologists knew by November 2013 that mark-recapture studies showed the Western Hudson Bay subpopulation had not changed appreciably since 2004 but none said so. This includes Steven Amstrup and Ian Stirling at Polar Bears International, Andrew Derocher (University of Alberta), and Nick Lunn (Canadian Wildlife Service), all of whom are (or have been) extensively involved in Western Hudson Bay polar bear research and have made recent statements to the media on this topic.

More details have emerged about the status of Western Hudson Bay (WHB) polar bears (reported a few days ago here), reported this morning in NunatsiaqOnline, excerpts below.

The story reveals that there are two Canadian Wildlife Service (Environment Canada) reports containing population estimates of Western Hudson Bay polar bears – one produced in 2011 and another in November 2013 (reversing the 2011 conclusion) – that have not been made public.

[In contrast, Nunavut Government reports on their 2011 population estimate, based on aerial surveys, were made public in both draft and final report formats (and have since been peer-reviewed and published)]

The conclusion of the 2013 report, quoted in this mornings article, suggests that some of our most vocal polar bear specialists have been misleading the public about the status of the Western Hudson Bay population for the last year.

Western Hudson Bay polar bear population is stable: press release

Posted on December 5, 2014 | Comments Off

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 resist government requests to tag and collar polar bears in MClintock Channel

Posted on October 20, 2014 | Comments Off

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.

Guest Post: Invasive Research is Alive and Well in Canada

Posted on March 2, 2014 | Comments Off

This is a guest post by Kelsey Eliasson, who blogs at Polarbearalley, with his thoughts on the issue of the invasive research involved in polar bear mark-recapture studies around Churchill, Manitoba — which, as you’ll see, is a far different situation than I described for Nunavut (previous posts here, here, and here on this topic. Map below to get you oriented).

Kelsey is a writer, artist and polar bear guide who has spent 14 bear seasons watching the polar bears of Churchill. For five years, he ran Churchill’s monthly newspaper published occasionally, the Hudson Bay Post. Currently, he divides his year between the Yukon, Churchill and, occasionally, Riverton, home of Manitoba’s largest moose statue.

Churchill is in the Western Hudson Bay polar bear subpopulation, governed by the Province of Manitoba, while the community of Arviat, also in 'Western Hudson Bay' is overseen by the Government of Nunavut.

Churchill lies in the Western Hudson Bay (WHB) polar bear subpopulation, governed by the Province of Manitoba, while the community of Arviat, also in the Western Hudson Bay subpopulation, is overseen by the Government of Nunavut – different governments, different rules – as Kelsey points out below.

Invasive Research is Alive and Well in Canada, by Kelsey Eliasson

The recent post about Foxe Basin was of particular interest to me, as I have been following the growing gap between the north and science for some time now. The stance taken by the Inuit is viewed as an inspiration by the guides over here in Churchill. For many years, we have tried to voice our deep concerns over the levels of handling and drugging that our bears (the Western Hudson Bay population) are subjected to on an annual basis.

This time last year, I tried to raise the topic for discussion after Andrew Derocher announced that ‘everything was on the table’ including feeding bears. At that time, the top polar bear researchers had sat down to discuss options for saving bears – except reducing handling and research – i.e. chasing bears down by helicopter and then shooting them with tranquilizers.

Foxe Basin aerial survey – a watershed moment for polar bear research, Part 1

Posted on February 24, 2014 | Comments Off

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.

Foxe Basin polar bear status – another stable population

Figure 1. Polar bear subpopulation regions defined by the Polar Bear Specialist Group, Foxe Basin marked.

Foxe Basin is a large subpopulation region (Fig. 1), with a total area of 1.18 million square km (Vongraven and Peacock 2011). It comprises Northern Hudson Bay and western Hudson Strait, and the area between western Baffin Island and eastern Melville Peninsula, with a large island (Southampton Island) in the middle (Figs. 2 and 3).
