Chasing Answers in the Arctic: Researching the Effects of Climate Change on the Porcupine Caribou Herd

Presented by Heather Johnson USGS Research Wildlife Biologist and Paul Leonard Arctic National Wildlife Refuge Supervisory Biologist
Tuesday, Oct. 15, 5 – 6 AKDT

This event was held with in person speakers at Fairbanks and Anchorage, at watch parties in Soldotna and Homer and on Zoom.

The Porcupine caribou herd is currently the largest in Alaska and one of the largest herds in North America. Each summer, it undergoes one of the longest terrestrial migrations on Earth to birth calves on the coastal plain of the Arctic National Wildlife Refuge. But what is the future of the herd given changing climate conditions? Join us to hear about how an innovative research project aims to discover whether and how a changing climate will impact the herd. Arctic Refuge Supervisory Biologist Paul Leonard will share with us the significance of the Porcupine caribou herd as a cornerstone of the ecological, cultural, and economic landscape of the Arctic Refuge, and as a vital part of the livelihoods and traditions of Indigenous peoples of the region, including the Iñupiat and Gwich’in. Lead researcher Heather Johnson of US Geological Survey (USGS) will discuss the research she is conducting on the Porcupine caribou herd in collaboration with partners including the refuge. Their research aims to understand the influence of changing climate conditions on summer habitat for caribou in the Arctic, the impacts of these changes on caribou behavior and population dynamics, and the implications for the future of the Porcupine herd. As part of the project, caribou wear video camera collars so researchers can ‘see’ life from a caribou’s perspective, footage we look forward to sharing with you!

Cow caribou carried video cameras which turned on every 20 minutes to takea 10 second video. This allowed researchers to see what they were eating, what habitat they were using, if they had calves and other important information.

This is a partnered program with the Campbell Creek Science Center serving as not only our monthly meeting but also their Fireside Chats monthly talk series.

Floating to the Hunt on National Wildlife Refuges in Alaska

This meeting was held on Tuesday, September 17, 2024, 5-6 pm AKDT
The recording of this event can be found below:

Presented by Barry Whitehill
Yukon Flats Deputy Refuge Manager (Retired)

Ivishak River in the Arctic National Wildlife Refuge

From the mountains to the lowlands, rivers can take you to wilderness hunting. Floating has been Barry Whitehill’s primary vehicle for accessing national wildlife refuges in Alaska in order to hunt moose, sheep, and caribou. He also just loves rivers. Barry’s love of rivers was honed through a career with the U.S. Fish and Wildlife Service which enabled him to traverse remote Alaskan rivers for work. His retirement in 2009 as the Deputy Refuge Manager at the 8.6 million acre Yukon Flats National Wildlife Refuge in central Alaska gave him the time and opportunity to undertake extended personal float trips. He has floated over 1000 miles of Alaska’s rivers in one summer! Barry knows Alaska rivers.

Feast or famine is often the dynamics of Alaska’s ecosystems. As a hunter in that setting, the difference between success and failure can be the ability to tap into the natural rhythm of the land. Barry considers floating to the hunt a great way to match the pace and terms of the Alaska landscape. Barry will share with us lessons learned in over thirty years of floating to these Alaska hunts. He will talk about some of his favorite rivers primarily on the Arctic, Kanuti and Yukon Flats refuges all accessed out of Fairbanks. He will also share tips for planning a float, logistics and gear.

Barry Whitehill’s biography in his own words:

I grew up in eastern Washington and considered myself fortunate to have public lands close at hand. Starting with my first elk at age 14, it became obvious to me that dropping into deep, dark holes and undertaking challenging floats on public lands consistently brought success as a hunter. Also, rivers and wild places rejuvenate my soul. Later, I found this true when living in Idaho, northern Nevada, and, since 1992, in Fairbanks, Alaska. I am a Friends of Alaska National Wildlife Refuges member and on the Board of the Alaska Chapter of Backcountry Hunters & Anglers. Both organizations do much to support our national wildlife refuges and our opportunities to float and hunt and enjoy these public lands.

Background on Hunting on Refuges

Some of you may be surprised to learn that hunting is one of the “Big Six” priority wildlife dependent recreational uses of national wildlife refuges along with wildlife viewing, wildlife photography, interpretation, education and fishing. These were established as priority recreational uses in the National Wildlife Refuge System Improvement Act of 1997. Some lower 48 refuges are closed to hunting to protect species where the populations are not large enough to support hunting or where hunting would conflict with other priority uses. All national wildlife refuges in Alaska are open to hunting except for very small areas adjacent to visitor facilities and the Skilak Loop Road on the Kenai Refuge where wildlife viewing, wildlife photography and small game specialty hunts (youth, bow, and falconry) are the priority uses. Protection of species is accomplished through game regulations usually set by the state. Many Alaskan households utilize wild meat as a big part of their diet.

Subsistence hunting for rural residents is also one of the purposes of all national wildlife refuges in Alaska as established by Congress in the Alaska National Interests Lands Act (ANILCA) of 1980.

Friends partnered for this program with the Alaska Chapter of Backcountry Hunters & Anglers, a group dedicated to “ensuring North America’s outdoor heritage of hunting and fishing in a natural setting, through education and work on behalf of wild public lands, waters, and wildlife.” They have been advocates for refuges, wilderness and wildlife including taking positions opposing the Ambler Road and defending the Malheur National Wildlife Refuge during the 2016 takeover and occupation by the Bundys.

Chickaloon Flats: A Hidden Gem on the Kenai National Wildlife Refuge

By John Morton, (retired Kenai Refuge Supervisory Biologist) Within sight of almost half of all Alaskans lies a little-known tidal estuary. Perched along Turnagain Arm on the northwestern Kenai Peninsula, the 27,000-acre Chickaloon Flats is the only part of the Kenai National Wildlife Refuge that touches marine waters. It represents 7% of the total estuarine area in Cook Inlet and Prince William Sound, the two water bodies that form the peninsula. As such, it’s a small but important part of the Pacific Flyway for migratory shorebirds and waterfowl.

But how important? Sadie Ulman, before becoming a biologist at Arctic Refuge, did her graduate research on shorebird use of Chickaloon Flats in 2009-2010. The last part of her thesis, which addressed that question, was published recently in the journal Waterbirds. Sadie documented that 23 of 37 common shorebird species breeding in Alaska use Chickaloon Flats during migration. With peak daily shorebird population estimates of 23,000 in the spring and 95,000 in the fall, this stopover site hosts a lot of birds for short periods of time. But Sadie took it another step, using stable isotope analysis of feathers to determine where six of those shorebird species spend their winter. Feathers maintain an isotopic signature of what was eaten during the relatively short period of feather growth. This allows individual shorebirds to be sampled during breeding to estimate the geographic origin of their feather growth during the previous nonbreeding season. A combination of values from three stable isotopes (d2H, d13C, and d15N) are used to infer feather molt origin on a broad geographic scale because predictable spatial patterns of d2H occur in precipitation on a continental scale, and d13C and d15N are then used to further distinguish if the feather was grown in a terrestrial versus marine environment. Sadie used drop nets and decoys to catch (and band) migrating shorebirds that stopped over on Chickaloon Flats, from which she pulled feathers. What did she find? Greater Yellowlegs using Chickaloon Flats likely molted in southwest Alaska, and Short-billed Dowitchers in southcentral Alaska. Lesser Yellowlegs likely molted in western Alaska and a latitudinal band across Canada, and wintered throughout the Lower 48. Least Sandpipers wintered from Oregon and south in North America but showed an isotopically similar possibility in Ecuador, Colombia, and Venezuela. Long-billed Dowitchers molted primaries across the western U.S. and Canada. Pectoral Sandpipers using Chickaloon Flats likely molted near the Rio de La Plata in southeastern South America!

Amazingly, this tidal wetland, hidden in plain sight from Anchorage (15 miles from Potters Marsh), has significant value as a stopover for many shorebird species breeding in Alaska. Belugas and brown bears also forage for silver salmon in the Chickaloon River and other parts of the estuary are used as haulouts by harbor seals. The good news is that Chickaloon Flats is conserved within the Kenai Refuge. The bad news is that it’s not protected from natural disasters. During the 1964 Great Alaskan Earthquake, the entire estuary dropped in elevation and was inundated by mud. Even today, Chickaloon Flats really does tilt downward to the east and south. However, as Sadie showed in a 2019 article in Northwest Science, the marsh is slowly recovering.

My Spring Volunteering with the Kodiak National Wildlife Refuge

By Barbara Ryan
Pompano Beach Florida Friends Member

It certainly was my pleasure to serve as a volunteer this spring at the Kodiak National Wildlife Refuge Visitor Center. Their summer seasonal employees had not yet started work and the Refuge asked Friends for help with this shoulder season. I started off helping with the spring break Bear Awareness Program for families, which provided educational hands-on kids stations to teach children bear awareness through age-appropriate scavenger hunts, collage making, coloring events, and face painting. Over seventy-five participated.

Bear awareness is an important subject on an island which is home to 3500 Kodiak bears, the largest subspecies of brown bears. Helping with this was my first task.

Providing visitor information was a big part of my job and included information on the gray whale migration around Kodiak Island, where to go tide pooling, how to find beach glass, assisting with hunting and fishing regulations, explaining the road and river systems and abundant hiking trails, birds and species reference lists and where to find them on the road system. I also registered participants for the Kodiak Refuge Science and Salmon Camp Program which continues to be hugely popular year after year.

Kodiak Refuge Visitor Center is a vibrant resource providing meeting space for trainings such as an Alaska Oil Spill Response Conference and community events such as an Alutiiq sponsored Native bead bracelet making workshop. The refuge visitor center is centrally located amidst several museums, the town of Kodiak Visitor Center, the Alaska Marine Ferry Terminal and cruise ship docks, all within walking distance.

Because the spring season is not as busy as summer, I had time to experience the history and fascinating culture from Kodiak archaeology to the cultural heritage of the Alutiiq/Sugpiaq people, and provide a memorable tour of the visitor center to visitors.

The staff was a delight to work with and I have made some new friends from this Friends of Alaska National Wildlife Refuges experience.

Nunivak Island: Home on the Range

By Kyra Neal, Wildlife Biologist, Yukon Delta Refuge

About 30 miles offshore from where the Kuskokwim River meets the Bering Sea, nestled in Shoal Bay, there is a small island village called Mekoryuk, home to around 200 mostly Yup’ik and Cup’ik people. In this place, the mayor is the same person who takes the trash trolley to the transfer station, the city office workers are the same people who teach kindergarten, the reindeer caretaker is the same person who jump started your ATV, and the elders stop by the roadside to share wisdom of their years growing up and to welcome you to their community on Nunivak Island.

Nunivak Island is also home to 700 muskox and 3,000 reindeer. Grazing has occurred on Nunivak Island for hundreds of years, first by caribou until they were extirpated in the late 1800s and then by introduced reindeer and muskox in the last century. The condition of their range was evaluated intensively in 1989 with 10 trend plots involving 40 quadrats and two transects for each location.

Since 1989, Nunivak Island has become increasingly connected to mainland Alaska with more flights, boating, muskox hunting, and tourism. Consequently, Yukon Delta National Wildlife Refuge partnered with the Natural Resources Conservation Service (NRCS) in 2022 and 2023 to reevaluate the range condition and survey the island and village of Mekoryuk for invasive species at two different spatial scales. One is a fine-tooth comb and the other is more of a broad-stroke brush.

Reindeer at the facility in Mekoryuk
Let’s start with combing the luxurious locks of the tundra. Arriving at each plot via an R-44 helicopter, we applied the same methodology to evaluate range that was used in 1989. Within these 40 20×50 cm quadrats, we estimated ground cover for each species including lichen, shrubs, forbs, grasses, bare ground, rocks, and even scat. In 10 of these quadrats, we measured production by a double sampling clip and weigh method. Changes in ground cover and productivity will tell us how grazing has affected the range. Certain lichens are favorites of reindeer and can be depleted to bare ground exposure when overgrazing occurs. For invasives, we scouted disturbed areas in Mekoryuk by foot and in our monitoring areas, combing the tundra for anything out of place. Roads, barge ports, ATV trails, airstrips were all observed by foot in search of non-native species and plots with a high percentage of bare soil.

Pulling out our broad-stoke brush, range was surveyed between the established transects. Using NRCS reconnaissance methods, we scored range conditions based on evaluating the amounts of lichen, bare soil, presence of grazing and scat on two acres between transects. For our invasive species broad brush, we evaluated bare soil vectors for invasive species to get to the interior of the island. We used aerial imagery of ATV trails and disturbed areas to help us identify potential hot spots for introduction of non-native plants to the ecosystem.

What did we uncover? Well, good news and bad news. The good news is there are no invasive species on the Yukon Delta Refuge. The bad news is we did find some fall dandelion on the road leading to the airport and up to the sewage lagoon in Mekoryuk. We removed as much of the fall dandelions as could be done by hand and notified the village council president of our finding. Our range evaluation showed that the western side of Nunivak was heavily grazed, but the rest of the island has high quality grazing range for reindeer to enjoy!
