Citizen Science & the Crown of the Continent


Swiftly shrinking glaciers in Montana’s Glacier National Park alarm scientists and guests to the mountainous 1.013 million-acre park along the Alberta border. In the previous half century, a lot more than half of Glacier’s ice pack has disappeared. All the glaciers have retreated.

To measure the impacts of a altering climate in the higher nation, the park and other public land managers enlist volunteers to monitor animals that may possibly be at danger of diminishing populations or even extinction due to elevated temperature, loss of glaciers, transform in habitat, and the demise of forage.

The Crown of the Continent Analysis Understanding Center, primarily based in West Glacier, Montana, recognizes that mountain goat and pika populations have declined outdoors Glacier, however the park’s investigation employees demands baseline information to examine modifications in these two higher-elevation mammals. In 2008, the group established the Higher Nation Citizen Science Project. Because then, a couple of hundred volunteers have collected information on species of concern—pika and mountain goats—that rely on cool temperatures of the higher nation for foraging and escape from predators.

For the previous 5 summers, my loved ones and I have volunteered to backpack into Glacier’s mountains and valleys to document pika and mountain goats and their habitat. We pack binoculars, a GPS with study internet sites preloaded, telescope, tripod, goat and pika survey types, and small envelopes to gather pika scat. Oh, and each and every of us pack a canister of pepper spray in case of a likelihood encounter with Glacier’s apex predator: the grizzly bear.

As we appear for pika poop, my husband, Lynn, and son, Bridger, scramble more than a boulder field among Canada’s Waterton Lakes National Park, exactly where we began our backpack trip, and Bowman Lake, exactly where we completed our 5 days in the higher nation. 

“Shhhh,” I whisper. “I consider I hear pika.”

Lynn cannot hear it. Bridger is skeptical. “It’s a marmot,” he says, and darn if the 23-year-old is not right. The great news is that marmot and pika generally share the exact same scree fields. The negative news is that we do not come across pika at this internet site.

“I located a haypile,” says Lynn, shining a super vibrant flashlight among meter-higher rocks. “It’s truly old even though. And the scat is all white.”

We search for an hour for proof: fresh scat, pika calls, and haypiles—piles of drying grasses, sedges, and wildflowers that can attain as big a meter in diameter and 1 meter higher. Through the Crown of the Continent field instruction session 5 years ago, we hiked to a pika internet site close to Two Medicine Lake. As we examined a haypile, a pika squeaked “eep!” and dashed below a boulder, carrying a mouthful of purple flowers. 

The endearing American pika is an herbivore that appears mouse-like but is rather associated to the rabbit and hare loved ones. At 120-175 grams, the cinnamon brown or gray fur balls shelter amongst boulders. As subnivian creatures, pika do not hibernate rather, they tunnel below the snow that can be many meters deep in Glacier each and every winter. They hide from predators, coyotes, weasels, ermines, eagles, and other birds of prey—and now climate transform. 

Summer season temperatures linger deeper into fall and spring, warming and melting glaciers at a quicker pace than ever documented just before. Species that have to have cool climate to survive may well not be in a position to relocate to greater, cooler elevations. Pika’s physique temperature at 104.two degrees can promptly raise to a deadly 109.six degrees even when the outdoors temperature is beneath 80 degrees. They do not sweat or pant so they have to have habitat—cool places—to protect against their physique temperatures from increasing dangerously higher.

According to the National Park Service, “Climate models predict that the typical temperature in North America will rise by two-10 degrees Fahrenheit by the finish of the 21st century. Northwest Montana’s typical temperature has currently risen two.34 degrees (1.eight occasions the international typical) in the final century, with higher elevation regions warming at an even quicker price.” This contributes to shrinking habitat as conifers encroach the alpine meadows, lower forage, and impede the pika’s capability to detect predators.

That is exactly where the glaciologists from Glacier National Park sound an alarm. They estimate the glaciers at 7,000 years old from the Tiny Ice Age. Prior to that, through the Pleistocene Epoch, which ended about 12,000 years ago, ice covered the Northern Hemisphere, lowering sea levels some 300 feet. Close to Glacier National Park, ice was a mile deep. 

These huge receding glaciers shaped the popular hanging valleys of Glacier. Glaciers sculpted the park’s iconic arêtes, horns, cirques, tarns, and chains of lakes known as paternoster lakes. Primarily based on present investigation models, all the glaciers will disappear by 2030.

None of the study internet sites we examined in 2016 and 2017 revealed present pika residents. Did they perish or move? Relocating appears unlikely provided that, in lots of instances, the subsequent closest scree and boulder fields are half a kilometer or a lot more away. Moving to greater elevation would make sense except Glacier has only six mountains more than three,000 meters, which is the far finish of the variety for pika.

There is some great news amongst the dire.  A new U.S Geological Survey (USGS) study released in July 2017 indicates that some critters are displaying “behavioral flexibility—the capability to swiftly transform behavior in response to short—or extended-term environmental modifications such as climate variability,” notes the study’s lead researcher, Erik Beever. 

“Given that species have to cope with variability in environmental circumstances more than a number of time scales, behavioral flexibility can enable some animals a signifies by which to swiftly and successfully cope with such variability, however with out committing to a lot more-permanent qualities that will not generally be helpful,” says Beever.

The researchers gleaned information from 186 research worldwide that looked at animals’ flexibility in dealing with climate modifications.

And for my favourite small mammal? The study reveals that, sometimes, pika exhibit versatile behaviors to keep away from and accommodate climatic tension by altering “foraging tactic, habitat use and heat-regulating postures.”

The seemingly unsuitable habitat may possibly be the pika’s new house, even though a lot more investigation is required to decide if pika in the Northern Rockies will be in a position to come across cool, snowy, and rocky territory.

Skiers should really care about the small fur balls due to the fact its decline is a harbinger of the decline of moisture in the mountains, stored as snowpack atop glaciers. That snowpack in the higher nation fills our streams and rivers. Glacier’s Triple Divide Peak is a hydrological apex with waterways flow into 3 important river systems to various oceans: the Pacific, the Gulf of Mexico/Atlantic Ocean and Hudson Bay/Arctic Ocean. 

As summers turn into hotter and drier across the West, Glacier and Waterton endure a lot more months of wildfires. While open now, at this writing, aspect of Glacier’s Going-to-the-Sun Road was closed to fires. What harms pika, harms men and women. It is uncomplicated to really feel a bit helpless. Just after all, what can a couple of lovers of winter and mountain spaces do to alter what seems to be the course of climate transform? One particular alternative is supporting The Crown of the Continent or 1 of the other 19 investigation and understanding centers that combine science and education to assistance preserve and defend critical areas for generations to come.
