Last fall, much of the world was riveted by the image of 30,000-plus Pacific walruses hauled out on the Arctic coast near the Alaskan village of Point Lay. Such scenes have become increasingly familiar as climate conditions shift and the walruses, one of the world’s largest pinnipeds, find that the summer sea ice on which they depend is disappearing. It’s a shift with potentially dire consequences, especially for young walruses.
With the loss of summer sea ice, walruses that would normally rest on floating patches of ice in small groups are hauling out on land in large congregations. When these large groups are startled, they rush back into the water in what is called a stampede. In the process, small young walruses can be crushed.

The U.S. Fish and Wildlife Service, Alaska Peninsula National Wildlife Refuge, the nonprofit Alaska SeaLife Center, the Federal Aviation Administration, residents and others across the state are doing their part to gain a better understanding of walrus response to climate change and disturbance and to prevent stampedes and minimize mortality.
In Point Lay, residents long have taken pride as stewards of the Pacific walrus, partnering with the Service to ensure that locals and visitors avoid disturbing the marine mammal. The Service has developed flight guidelines for local air carriers and pilots and issues advisories when a haulout forms. The Service also works with the FAA to establish temporary flight restrictions; and the Point Lay community works directly with air carriers to establish new flight paths. These efforts have kept walrus deaths remarkably low.
Some 800 miles south of Point Lay, Alaska Peninsula Refuge is working with the Alaska SeaLife Center, whose scientists and veterinarians began a study in 2011 about walrus responses to disturbance. They placed weather-proof cameras at several walrus haulout spots to record images of the haulouts from May through September. One monitoring site is on Cape Seniavin near the refuge. It is a favored resting area for male walruses feeding in nearby shallow waters.
“You smell the walruses long before you see them,” says refuge pilot/biologist Dan Pepin. “As I laid on my stomach and peered over the bank to the northwest, I saw the walruses both on the beach and negotiating the surf. It was truly an amazing experience.”
Cape Seniavin is a popular destination for wildlife viewers and ivory collectors, setting the stage for stampede events. Even though the haulout site is not on the refuge, the refuge plays a key role in keeping the monitoring cameras operational. Every 60 days, a refuge pilot visits the site to maintain camera platforms and replace batteries and SD memory cards.
“I am happy that we are in a position to help with the walrus cameras,” says refuge manager Susan Alexander. “Our logistical capability operating on the peninsula allows us to contribute to the conservation of this fantastic local resource.”
The refuge helps the SeaLife Center stretch funds and increase monitoring efforts, and Service law enforcement officers and scientists at the center educate visitors about why walruses should not be disturbed, how to avoid doing so, and the consequences of failing to abide by the Marine Mammal Protection Act.
From understanding walrus response to changing climate conditions to minimizing the untimely deaths of young animals, partners on and off refuges are helping to increase the odds that these amazing creatures will be around to thrill future generations.
Goo goo g’joob
I’m proud to say that this is an issue where my state of Massachusetts has been way out in front. Our current policies make this a non-issue. In fact, I can’t remember the last time we had a walrus stampede around here.
“Every 60 days, a refuge pilot visits the site to maintain camera platforms and replace batteries and SD memory cards.”
Ah yes...much like the BLM uses ATV’s an ORV’s to patrol areas and enforce ATV and ORV bans.
The sea ice has disappeared every summer since we warmed out of the last ice age. It will continue to do so until we cool into the next one in 10,000 years or so. Then the walrus’ will have to move south or die off.
The situation is more likely do to an exploding walrus population than to “climate change”.
Partially digested clams from the belly of a freshly killed walrus are a welcome lunch amongst the local Indian tribes - Aleuts, I believe.
They stampede? Well, whatcha need right there is some walrus cowboys. We call em walboys. You get yourself 20, 30 walboys and you can keep that herd under tight control. Them walboys just ride to the front of that herd on their salmon, hootin and hollerin and firing off their cell phones, and them walrii will calm right down.
“Home, home on the beach
Where the Walrii sit eating a peach.
Where seldom is heard
A discouraging word
And the little walrii don’t get squished.”
Just keep Barney Frank away from the water!
that these amazing creatures will be around to thrill future generations of ivory hunters ...
Ivory hunters. You mean like Ivory Joe Hunter? He was a pretty good singer, but I don’t know if he was interested in walrii.
I am the Egg Man...
There used to be men that hunted walrus for their ivory tusks and will be again one day.
Sincere thanks for your reply. That was a poor attempt on my part to be clever and funny. I’ll have to leave that to the pros.
100,000 unemployed comedians, and I have to stick MY nose in.....
Vwon’t anyone save the walruses from climate change?
