Walrus researchers from the US Geological Survey have a new report on the history of walrus haulouts in the Chukchi and Bering Seas – yet their media efforts (via press release and interviews) fail to mention the relationship between fluctuating size of walrus haulouts and fluctuating walrus population size that is evident in that history. In fact, overall population size is not mentioned at all.
Two articles came out over the weekend that announced the results of this new joint US-Russian initiative [PBS, Walrus beaching in Alaska might not be as harmful as it looks. Here’s why – 31 July 2016 and ADN, Alaska and Russia join forces to create 160-year database of walrus haulouts – 31 July 2016]
But neither articles nor the new USGS paper they are touting (Fischback et al. 2016) mention the huge summer/fall haulouts of females, calves, and juveniles that were documented in the 1970s that coincided with the huge population size at that time, which crashed in the 1980s.
Only now has the population grown (to at least 200,000) to the point that huge haulouts are again being reported – conservation has done it’s job. But when walrus numbers get too high the animals out-strip their food source and numbers plummet, as they did in the 1980s (Fay et al. 1989; Garlich-Miller et al. 2011). See my fully referenced summary paper, Crockford 2014 (On The Beach: Walrus Haulouts are Nothing New).
Here’s the concern: When (not if) a population crash happens again, will it be blamed on global warming rather than natural causes? According to the PBS article:
“The database is supposed to help federal officials with conservation, especially as more ships start sailing through the newly open waters. The U.S. Fish and Wildlife Service is determining whether walrus should be listed as a threatened species.” [my bold]

So, I guess they didn’t all die because of lack of sea ice in the Chukchi Sea. I said back on 28 August, just after the some unauthorized photos were publicized, that this haulout looked just as large as last year’s, if not larger (walruses are occasional prey of polar bears).
Now confirmed by an official US Fish and Wildlife Service estimate of 35,000 – not 36,000 mind you, or 34,000 – it was definitely 35,000. Odd, that. And surprisingly, they didn’t bother going out to count them until the day President Obama came to town. Would FWS have even bothered to get a count if there hadn’t been something newsworthy to tie it to?
Even more strange is the fact that this year, there was no accompanying hype. There were no links in any of the stories to FWS or USGS propaganda website pages, like there were last year (nor even a link to a press release). No mention of the FWS plan to have walruses declared ‘threatened with extinction‘ because of global warming. And no mention of prosecution of the photographer who took the photos on 23 August, from the required distance, but without a permit. Note the permit number stamped on the official NOAA photo provided below (taken 2 September 2015), which few outlets carried, probably because it looks nothing like a photo of walruses on a beach:
It appears that this year 35,000 walruses on a beach is a non-story. Go figure. Excerpts from the one, widely-circulated story below, from three days ago. See previous post for more walrus background, map, and video.

A photo of a mass walrus haulout at Point Lay, Alaska taken a few days ago from a distance show thousands of animals. But no one’s counting because apparently, no one’s interested.
The picture on the left (above, courtesy Alaska Dispatch News) was taken 23 August by global warming activist photographer Gary Braasch, the day after a news report appeared about the US Fish & Wildlife Service and aviation authorities asking the media to approach USFWS about walrus photos and information that gave no hint that a large haulout of walruses was already in place (22 August 2015, “Federal agencies, Point Lay seek to minimize walrus disturbances” ):
“Federal agencies are stepping in to shield a North Slope village from the possibility of a deluge of international attention should a large walrus haulout develop nearby, as it has in years past — agreeing to act as an information clearinghouse on behalf of the Native Village of Point Lay.” [my bold]
Here is what the global warming activist site that published the pictures says about the haulout:
“Thousands of Pacific walrus are coming ashore near Point Lay, NW Arctic coast of Alaska. The huge sea mammals and young began coming up on this barrier island along Kasegaluk Lagoon about August 20, according to local natives. This is one of the earliest known summer haul outs of the walrus along the Alaska coast of the Chukchi Sea, according to wildlife biologists.” [my bold]
They say “thousands.” But the photos taken, reproduced in the Alaska Dispatch News story I read, were taken from a greater distance than the famous photo of ~35,000 animals released by government officials last year and looks like the total could be as large, or larger, than the 2014 haulout.
Said a Washington Post story (27 August 2015):
“The U.S. Fish and Wildlife Service confirmed to the Post Wednesday evening that a mass of walruses had “hauled out,” or gathered on shore, near the remote community of Point Lay. The service did not estimate the number or provide images. But photojournalist Gary Braasch has posted dramatic photographs, taken during an Aug. 23 flyover, of what appear to be at least several thousand walruses crowding onto a barrier island.” [my bold]

Now we have poor hunting conditions in the Bering Strait touted as evidence that “walrus migration patterns have changed” with the implication that this is because “…the past eight years have had the eight lowest amounts of summer sea ice on record” due to man-made global warming.
A subsistence lifestyle is hard, particularly so if it depends on a highly mobile, migratory herd animal. Think Barren-ground Inuit caribou hunters, who often starved because herd sizes declined for a few years or moved unpredictably.
Many factors – seasonal weather, last year’s winter conditions, size of the herd, food supply – all affect where and when a migratory herd will move and the likelihood it will be positioned for optimal harvesting by hunters. Add another highly variable factor into that – Bering Sea ice – and you have a highly unpredictable food supply, especially if you sit in one spot (like on St. Lawrence Island) and expect that migratory herd animal to come within reach.
Hunting walrus from St. Lawrence Island depends on just the right combination of ice and winds. Too much ice is not good, too much open water is not good, and too much wind is not good.
Alaska Dispatch, courtesy the Associated Press, reports St. Lawrence natives are again short of walrus meat because of “warm temperatures”: “Warming temps push walrus north, leaving Alaska villages without traditional food source” (Rachel D’Oro, The Associated Press, August 6, 2015). And the caption of the above USGS (A. Sonsthagen) photo predictably implies all current hunting troubles can be blamed on climate channge:
“The walruses in this July 2012 file photo are hauled out in the Eastern Chukchi Sea. Walrus migration patterns have changed as sea ice and other environmental factors have shifted — and that’s spelled trouble for Alaska Native communities who hunt them for subsistence.”
The people of St. Lawrence Island and the Bering Strait that depend on walrus for subsistence have my sympathy, they indeed have a hard life – but this is not a tale of woe about the status of Pacific walrus and changing summer sea ice.
Bering Strait natives hunt walrus in spring, from mid-April to early June (Huntington et al. 2013). All indications are that walrus are moving differently than they used to in summer because the population is now very large. As far as I know, there is no new population information on walrus that wasn’t available last year, when I covered this topic extensively (Crockford 2014; video below).

More bad science: US biologists successfully used a scientifically flawed model to get polar bears listed as ‘threatened’ and thus emboldened, went on to do the same for walrus.
The intricate US Geological Survey model of ‘expert opinion’ that was used to support the listing of polar bears as ‘threatened’ under the US Endangered Species Act (ESA) has been soundly rejected by the world’s leading conservation organization, the IUCN,1 which has has tightened its rules for using “future conditions” (e.g., effects of global warming) in generating Red List assessments. That IUCN condemnation means the USGS model was never “the best available science” for evaluating the status of polar bears ̶ it was (and still is) substandard, inadequate science that makes a mockery of serious conservation efforts.
However, not only has this flawed model continued to be used by the USGS for polar bears, it has also been used to assess the conservation status of Pacific walrus, which are now officially “candidates” for being listed as ‘threatened’ (US Fish and Wildlife Service 2011).2

A new day, a new lawsuit by environmentalists: this time, the species-on-a-pedestal is the same population of Chukchi Sea walrus that generated a news frenzy last month, which apparently still has legs.
