Thesis Defense: Kristen Richardson!

As part of the Wildlife Seminar this Monday, June 3, Kristen Richardson will be defending her Master’s Thesis, “Using non-invasive techniques to examine patterns of black bear (Ursus americanus) abundance in the  North Cascades Ecosystem.”

Her talk begins at 3:30 p.m. in Kane 130 and is open to the public, so come support the culmination of her research at SEFS!

And what will Richardson be talking about?

From 2008 to 2011 a large, multi-agency project deployed barbed-wire hair-snag corrals to collect DNA samples from black bears (Ursus americanus) in the North Cascades Ecosystem (NCE) of Washington State. Using the genetic and detection data, Richardson examined the influence of human activities and habitat characteristics on bear abundance across heterogeneous landscapes of the NCE.

No other research to date in Washington State has examined the influence of habitat and anthropogenic variables on black bears across such a large geographic expanse, and the results of her study should help guide management of black bear populations in the NCE. This research is especially important given the challenge of maintaining viable populations of a long-lived species with relatively low fecundity.

Richardson’s committee chair is Professor Aaron Wirsing, and the other members are Bill Gaines and Josh Lawler.

SEFS Students Descend on Yellowstone

Yellowstone

Clear blue skies greeted the research crew on a morning snowshoe hike to a wolf kill site in the Lamar Valley.

Before the crack of dawn this past Saturday morning, March 23, a caravan set off on the long, long drive to Gardiner, Mont., at the edge of Yellowstone National Park. On board were 15 students and three faculty members from the School of Environmental and Forest Sciences (SEFS), all heading out to spend roughly a week of field study in the northern Rockies as part of a spring course, “ESRM 459: Wildlife Conservation in Northwest Ecosystems.”

Led by SEFS Professors John Marzluff, Monika Moskal and Aaron Wirsing, the group will be using the Northern Range of Yellowstone National Park, between Gardiner and Cooke City, as a staging area to explore patterns of corvid, and especially raven, distribution; elk anti-predator behavior (vigilance); and wolf predation. The class also addresses regional management issues, including wolves and bison leaving the park.

It’s a glorious time to be trekking through the Yellowstone backcountry. The group has special access to remote research areas, tourists are few and far between, scores of bison are out hoofing through the snow, and students occasionally catch glimpses of wolves, grizzlies and other wilderness gems.

Professor John Marzluff helps orient students during their first full day in the park.

Of course, it’s a working research visit, and students spend long days trudging through the park—often at the mercy of the elements, which at this time of year can be ornery, if not downright savage. Then, after they return to campus on March 30, they begin working on group projects based on data collected. They will present their findings to the public at the end of spring quarter.

But even in the worst weather conditions, when even your expedition thermals can feel threadbare and drafty, how could you say no to this kind of hands-on experience in the wilds of Yellowstone?

Grad Student Spotlight: Carol Bogezi

Field work for graduate wildlife students often involves a great deal of patience. You might spend days tracking wolves or grizzlies before you catch a glimpse, or even have to wait months trying to spy your first lynx.

Bogezi and her “big kitty.”

Not so for Carol Bogezi, a first-year Ph.D. student at the School of Environmental and Forest Sciences (SEFS). She struck pay dirt on her first time out, capturing a full-grown, 150-pound male cougar in the North Fork Creek drainage of the Marckworth State Forest, east of Duvall, Wash. She had set out to the study site with Dr. Brian Kertson, a SEFS alumnus and cougar expert who now works with the Washington Department of Fish & Wildlife, when they came across the treed cat.

“When you see one in a tree, you think it’s just a big kitty,” she says. “But when you have it down and are measuring it in your hands, it’s really big!”

Bogezi grew up outside of Kampala, Uganda, and moved to Seattle this past September to begin graduate work with Professor John Marzluff. Back home, she had most recently been studying the habitat and distribution of crocodiles in Kidepo Valley National Park, and she had done similar work with elephants and lions. What drew her to the University of Washington was the chance to study in a totally new environment, and also to focus on the human dimensions of wildlife interactions and management. Studying cougars in western Washington was a perfect fit.

She’s still fine-tuning her research question, but Bogezi is especially interested in investigating how wildlife responds to human activities, such as logging or hiking, in natural areas. Also, as in the case with cougars, how do you mitigate conflicts—especially within her study area, which extends up to the Seattle suburbs and the Interstate 90 corridor? Or, in cases where perception can be more damaging than reality, can you change human attitudes toward wildlife and facilitate greater community understanding and tolerance of local species?

Beginning later this spring, she’ll get another opportunity to explore some of those questions in a separate joint research project with Marzluff and Professors Stanley Asah and Aaron Wirsing. The study, recently awarded funding by the Institute of Forest Resources at SEFS, will approach the management of wolves in eastern Washington—specifically, whether it’s possible, via rancher compensation or other economic incentive programs, to support a healthy and sustainable wolf presence in the state.

Carol Bogezi and Croc

Bogezi says the challenge with wolves is similar to situations she experienced in Uganda involving elephants damaging crops, or lions taking livestock. She recalls showing up to heated meetings with farmers who had lost animals, or who had their fields trampled, and sometimes they’d even come waving spears. “If it’s touching their livelihoods, that’s where there’s conflict,” she says.

But the issue with wolves could be more emotional than practical—in part, Bogezi believes, because we’re raised on stories like “Little Red Riding Hood” that teach kids to fear and even hate wolves. Whatever the root causes or potential solutions, though, Bogezi is excited to get out and learn firsthand what’s driving perceptions. “I want to find out what people really think about the wolves,” she says, “and get ideas from the ranchers themselves about how to manage this conflict.”

When she completes her graduate work, Bogezi hopes to return to Uganda and, if possible, continue working there with the Wildlife Conservation Society (WCS). She would love to replicate her research here back home, and to help mitigate wildlife conflicts in other geographical areas around Uganda and Africa.

By then, she’ll be thoroughly field-tested, having handled crocodiles, held a full-grown cougar in her lap, and stared down spears in the line of research. Certainly makes you wonder what kind of challenge she’ll take on next!

Students to Investigate Raccoon Ramblings

Thomas and Klein

Terence Thomas and Amy Klein

Whether you’ve ever been startled by some late-night shuffling in a trash can on campus, or a scratching in the bushes by the bus stop, there’s a good chance you’ve spied a pair of glowing eyes in the twilight. Nighttime, after all, invites a host of critters into the open, and raccoons are one of the more familiar sightings for after-hours visitors.

But even if bumping into raccoons seems inevitable, are these encounters totally random? What do we really know about the habits of these nocturnal nibblers? Where are they foraging, and what are they finding? More importantly, are there statistical correlations between their presence and certain features of the landscape?

This winter, three seniors in the Environmental Science and Resource Management (ESRM) program—Terence Thomas, Amy Klein and Ben Krabill—hope to shed some light on these questions.

Raccoon

Do you recognize this guy?

“You see raccoons all the time on campus,” says Thomas, “but we don’t know much about them—what they’re doing, and why they’re doing it.”

In search of some answers, they applied for and received a $250 Capstone Project Grant from the Director’s Office to help purchase camera equipment and other supplies for their senior project. They’re still fine-tuning their proposal, but the general plan is to use motion-sensor cameras to capture images of raccoons at night.

For 25 nights during the winter quarter, they’ll set up three cameras at different locations each night, from 9 p.m. to 8 a.m., providing three data samples every day.  As they sift through the collected images, says Klein, they’ll assess each camera site and evaluate factors such as nearby vegetation, distance to garbage cans or a water source.

They’re looking to identify a relationship between the physical environment on campus and raccoon distribution. “We’ll be very excited,” says Thomas, “if we collect strong statistical evidence that there are major features of the landscape that impact why raccoons are found in certain areas.”

Raccoons

Test runs with the cameras have already produced multiple sightings.

Their findings have potential to help in the future management of raccoons on campus, says Aaron Wirsing, a professor of wildlife ecology at the School of Environmental and Forest Sciences, who is advising the three students on the project. “By photographically documenting raccoons all across campus, their project should better our understanding of how this species uses urban environments, how certain human activities might attract raccoons, and how we might change our behavior to mitigate human-raccoon conflict.”

So, depending on the results of their investigation, the next time you stumble across a raccoon on campus, you might know why!

About the Grant

ESRM Senior Capstone students are encouraged to apply for Director’s Office financial support to defray costs incurred to complete their ESRM capstone. Funds are at three levels—$50, $150 and $250—and are awarded in Autumn, Winter or Spring quarters. Students must be registered for a capstone course (ESRM 494, 495 or 496) during the quarter of the award. The School Curriculum Committee will allocate the funds. Only one award is allocated per undergraduate student. The deadline is the second Friday of each quarter, and you will be notified of your award no later than the fourth week of the quarter.
