Rewilding a Rescued Ocelot in Peru

While doing field research in Peru a few months ago, SEFS doctoral student Samantha Zwicker helped rescue a young male ocelot (Leopardus pardalis) in the remote community of Lucerna along the Piedras River.

Khan, rescued at a little more than a month old.

Ocelots, also known as dwarf leopards, are elusive wild cats that are found in the jungle throughout South America, and even up through Mexico and the southern edge of Texas. This particular ocelot, named Khan, is now about 4.5 months old. He had been removed from his mother at about one month and was living in a box, malnourished and dehydrated. Once rescued, he immediately bonded with one of Sam’s research partners, Harry Turner, a herpetologist and photographer from the United Kingdom (and also a former soldier who served in Afghanistan). Harry has since made the rather incredible decision to spend the next year rewilding Khan and getting him ready for reintroduction back into the Amazon ecosystem on his own.

That task is daunting on multiple levels. First, an ocelot has never before been successfully reintroduced to the wild. Then there’s the fact that ocelots are nocturnal, which means Harry will be living alone in the jungle for a year (or longer), walking every night with Khan without light, and sleeping during the day. It’s a huge commitment, which might explain why all of the other ocelot experts Sam contacted passed on the challenge. But it also presents a tremendous opportunity to expand our knowledge of ocelot behavior, as well as a chance to assist future efforts to reintroduce South American cats at a larger scale.

As Khan’s “mom” for the past couple months, Harry has been slowly teaching him about the jungle, and about being an ocelot. Khan is already navigating the jungle and streams, swimming, prowling and catching prey, and becoming aware of the dangers the jungle can pose—including humans. In the next year, he will become fierce and agile, taking on prey in the trees and on the ground his size and larger.

Khan, now 4.5 months old, already growing and developing skills quickly.

One of Sam’s advisors, Renata Pitman, is a cat specialist and veterinarian who has been working in the region since 2000. She is advising the reintroduction project along with Miryam Quevedo and Jesus Lescano, two veterinarians with San Marcos University who will be teaching students in the field and monitoring Khan’s health. They’ve already secured permits to reintroduce Khan, and the plan is to release him eventually at a location that will be surrounded by conservation lands and away from any settlements.

In order to cover the costs of this unprecedented rewilding project, Sam has launched a crowdfunding page to support Harry through his year with Khan, from permits, veterinary and basic food needs to other equipment and resources to assist his “mothering” (such as bite-resistant gloves and sleeves). The baseline goal of $13,490 is designed to cover essentials for Harry and Khan, and there are higher-end goals, as well, if they raise enough money.

It’s a fascinating project, with potential to impact conservation and reintroduction efforts across the region, and we’ll be following their progress closely.

So good luck, Harry, for what will certainly be an unforgettable year for you and Khan!

John Tylczak to Host Third Photography Exhibition at SEFS

This October, we are excited that local photographer John Tylczak will be hosting his third exhibition in the Forest Club Room!

John grew up in Shelton, Wash., where four generations of his family have lived since 1885 (his grandfather, in fact, was the executor of Agnes Anderson’s estate). The black-and-white portraits he will be showcasing come from his broader collection, Views from the Northwoods: 1983-1995, which captures the faces of the Washington timber industry in the mid-1980s and early 1990s—from fallers and rigging crews, to loaders and transport workers, log scalers and mill workers. John’s collection includes more than 1,500 photographs, and the 10 images he’s sharing this year will focus on shots from shake and shingle mills that have all since closed.

The exhibition will kick off on Wednesday October 5, and run through the end of the month. It will be open to the public during normal weekday business hours, 8 a.m. to 5 p.m.

We heartily encourage you to come by and enjoy John’s powerful photographs!

2016 Pack Forest Summer Crew: Season Recap

For nine weeks this summer, five SEFS undergrads worked as interns down at Pack Forest getting immersive, hands-on field training in sustainable forest management. The students—Paul Albertine, Dana Chapman, Dana Reid, Chris Scelsa and Robert Swan—were part of the annual Pack Forest Summer Crew, and they recently wrapped up another successful season.

2016_09_summer-crew-recap2This year, the students got to work with several SEFS graduate students, as well as Jeff Kelly, the forester at Pack Forest. They participated in a wide range of activities, including a great amount of time measuring 85 permanent forest plots from the Continuous Forest Inventory (CFI) project. Doctoral student Emilio Vilanova says they became true field experts and were able to update vital information for the sustainable management of forests at Pack.

Other tasks for the students included assisting Matthew Aghai with his doctoral research, both at Pack Forest and at the Cedar River Watershed, and helping maintain a throughfall exclusion project led by Professor Greg Ettl and doctoral student Kiwoong Lee. They were critical in the upkeep of Pack Forest’s trail network, as well as the measurement of additional small-scale research projects, from regeneration surveys to the installation of other research plots. They also got to take three field trips, including official visits to Rainier Veneer and Silvaseed Company facilities, along with a two-day camping trip to the Cedar River Watershed.

In short, as always, the Pack Forest Summer Crew had an incredibly packed, productive and memorable internship. Take a look at a gallery of photos from their summer!

Annual Salmon BBQ: October 5!

For countless students around the country, the end of summer can trigger the cold Pavlovian sweats of a new school year. Around here, though, you’re far more likely to get the meat sweats this time of year thanks to our Annual Salmon BBQ, coming up on Wednesday, October 5, from 4:30 to 6:30 p.m. in the Anderson Hall courtyard!

2016_08_Salmon BBQIn case you haven’t been to the Salmon BBQ before, we have this autumn feast down to a beautiful, mouth-watering science. Once again, SEFS alumnus Steve Rigdon (’02, B.S.) will be providing the salmon, caught using traditional Yakama fishing techniques. Luke Rogers (’99, B.S.; ’05, M.S.) will continue his long-running role of overseeing the grilling operation using fir and alder wood from Pack Forest, which forester Jeff Kelly will hew and haul up beforehand. Professor Emeritus Steve West will set up a few kegs from Big Time Brewery, and Professor Emeritus Bruce Lippke will have an assortment of wines on hand for you to sample. In addition to the salmon, we’ll be providing ample corn on the cob, chips and salad, but the rest of the meal is a potluck, so please bring a side dish, snack or dessert item to share!

All alumni, students, staff and faculty are invited, and we heartily encourage you to bring friends and family. The event is free—and awesome—and no RSVP is required, and we will have plenty of salmon for all.

Also, if you’re able to assist with set-up or clean-up, please contact Karl Wirsing to make sure we have enough help before and after the event. We’ll start getting ready around 3 p.m., and we’ll need even more hands to help clean up afterward from 6:30 to 7 (ish). If you can spare a few minutes at either end, that would be tremendously appreciated!

That’s Not All!
Come a little early to the Salmon BBQ and catch the Distinguished Alumni Seminar, which will feature Randy Dahlgren (’84, M.S.; ’87, Ph.D.), a professor of soil science and biogeochemistry in the Department of Land, Air and Water Resources at the University of California – Davis. His talk, “From Subduction to Salmon: Geologic Subsidies Drive High Productivity of a Volcanic Spring-Fed River,” will run from 3:30 to 4:20 p.m. in Anderson 223 as part of the SEFS Seminar Series—ending just in time for the start of the festivities downstairs in the courtyard.

We invite you to take some time, as well, to browse through a wonderful photography exhibition in the Forest Club Room, where photographer John Tylczak has once again generously loaned 10 images from his collection, Views from the Northwoods: 1983-1995. These large, black-and-white photos capture the Washington timber industry in the 1980s and early ’90s, and this year his prints will focus on shots from area timber mills—including the beautiful image below. They will be on display throughout the month of October, so even if you can’t make the Salmon BBQ we encourage you to swing by Anderson Hall another time to enjoy these photographs.

It’s going to be a great kick-off for the fall quarter, and we sure hope to see you there!

SEFS Students Lead Doris Duke Scholars into the Field

This summer, a cohort of undergraduates from around the country spent two months at the University of Washington working on various research projects as part of the Doris Duke Conservation Scholars Program, an experiential learning program that aims to build more diversity and inclusion in the conservation community.

As part of the two-year program, Doris Duke Scholars spend their second summer working as interns with UW graduate students, and this year two SEFS doctoral students—Caitlin Littlefield and Clint Robins—served as mentors for five interns. They guided their students through eight weeks of rigorous hands-on field research, and then, on Wednesday, August 10, those interns joined others from their cohort and presented posters of their research at a culminating summit in the Fishery Sciences Building.

SEFS alumnus Brian Kertson (’01, B.S.; ’05, M.S.; ’10, Ph.D.), left, helped guide the project along with Niki, Clint and Kyle.

Caitlin mentored three interns—Alicia Juang from Harvard, Savannah Steinly from the University of Maryland, Baltimore County, and Ethan Bott from the University of Wisconsin – Stevens Point—and she led them to the Methow Valley to study how terrain-driven climate variability influences patterns of forest recovery. Focusing on the 2006 Tripod fire, which burned more than 70,000 hectares north of Winthrop, Wash., their crew measured thousands of juvenile conifers, deployed temperature and relative humidity data loggers, and ate plenty of ice cream. The interns each carved out an independent research project, which they showcased at the final summit: Alicia assessed how erosion potential influences conifer recovery; Savannah processed dozens of soil samples to characterize how soil properties vary across the study area; and Ethan assessed how well indices derived from remotely sensed imagery can predict conifer recovery.

Near Issaquah, Clint was working with two other Doris Duke Scholars, Niki Love from Cornell, and Kyle Mabie from Colorado State. They spent their summer studying cougar (Puma concolor) foraging behavior under the auspices of the West Cascades Cougar Project. Niki’s project focused on edge effects, and the degree to which habitat transitions were correlated with successful cougar kills. Kyle compared kill site habitats between individual cougars to determine whether different cougars use different forest types when hunting prey. Due to the nature of data collection for their projects, as well, both interns were consistently able to work together in the field.

It’s great to see our students so involved in the Doris Duke program, helping train future scientists and expanding the voices and perspectives in the conservation movement!

Migrations in Motion: An Animated Map of Climate-Driven Species Movement

The Nature Conservancy (TNC) recently developed an incredibly cool animated map that depicts how more than 2,900 species of birds, mammals and amphibians might migrate in response to rising sea levels and temperatures. The flow model, called Migrations in Motion, draws from research published in Ecology Letters in 2013, “Projected climate-driven faunal movement routes,” which Professor Josh Lawler coauthored with Professor Julian Olden from the School of Aquatic and Fishery Sciences, former SEFS grad student Aaron Ruesch (’11, M.S.), and Brad McRae, a senior landscape ecologist with TNC.

The map drew some immediate press coverage, including in Wired, which rightly calls the animation “mesmerizing, if unsettling” in its story, “Here’s Where Species Will Flee Because of Global Warming.”

Unlike the idle screengrab below, the actual map pulses with color and activity. Take a look!

Professor Sarah Reichard: 1957-2016

2016_08_SarahReichardOn Monday, August 29, our community woke up to the heartbreaking news that Professor Sarah Reichard passed away while leading a UW Botanic Gardens tour in South Africa. We can’t begin to express our shock and sadness at the loss of such a tremendous person and scholar. Our thoughts are with her husband and all of her family, friends, colleagues and students.

Sarah was born on December 16, 1957, and grew up in New Orleans and North Carolina. She earned her bachelor’s in botany from the University of Washington in 1981, and then her master’s (1989) and Ph.D. (1994) from the School of Environmental and Forest Sciences. Her research and teaching interests included the biology and ecology of invasive plants, as well as the recovery of rare species. Her courses on campus ranged from plant identification to public presentation in horticulture, and she led unforgettable botanical tours from Cuba to South Africa.

“Losing Sarah has been devastating to our community,” says SEFS Director Tom DeLuca. “Sarah gave everything in directing the UW Botanic Gardens, and she absolutely loved the Arboretum and Center for Urban Horticulture. She was a noted scholar in plant conservation and invasive ecology, and well loved and respected as a colleague, friend and faculty member. Sarah was also dedicated to educating children on the importance of nature in their lives and used her position as director to expand our role in K-12 education, including establishing hugely successful programs like the Fiddleheads Forest School. We are all still reeling from her loss and know there is no way to replace, or forget, her incredible talents and countless contributions.”

Dean Lisa Graumlich of the College of the Environment shared a wonderful tribute to Sarah on Friday, September 16, and we encourage you to read many other beautiful reflections in the blog comments below and on stories at the UW Botanic Gardens and the American Public Gardens Association.


Memorial Set for October 13
We will be holding a celebration of life in honor of Sarah on Thursday, October 13. The celebration will be a two-part event, and guests are invited to attend either or both parts.

The first part of the celebration will be at the Washington Park Arboretum from 2 p.m. to 3:30 p.m. Guests are asked to meet in Wisteria Hall at the Graham Visitor’s Center at 2 p.m. From there they will be given a map indicating three separate areas around the park where guest speakers will be sharing stories of Sarah. The speakers will remain at the areas and will be giving informal chats. Each chat will last approximately 15 minutes.

Later that afternoon, we will host a more formal celebration at the Don James Center in Husky Stadium. This program will begin with a reception from 5:30 to 6:30 p.m., followed by a formal presentation featuring several speakers from 6:30 to 8 p.m.

Please mark your calendars to join us in honoring Sarah, and we hope you’ll RSVP as soon as possible . We look forward to seeing you there.


Two funds have now been set up in Sarah’s honor:

1. The Professor Sarah E. Reichard Endowed Fund for UW Botanic Gardens will support the UW Botanic Gardens for public education, outreach, student education, research and general maintenance and improvement of gardens and plant collections.

2. The Sarah Reichard Endowed Fellowship will support graduate students within the School of Environmental and Forest Sciences who are engaged in studies with the UW Botanic Gardens.

New Faculty Intro: Brian Harvey

Brian Harvey might not be able to pinpoint the exact moment he knew he wanted to be a professor, but he can definitely recall a series of “pinch me” moments that gradually crystallized his dream—a dream he’s now realized, as he will be joining our faculty this spring as an assistant professor of forest ecosystem science and services!

Brian, who was born in Cleveland but spent most of his childhood in the San Francisco Bay Area, double-majored in geography and environmental studies as an undergrad at UC Santa Barbara. After he graduated, one of his first jobs was with an environmental consulting firm, where he was involved in a lot of remediation clean-up at industrial sites. “It was a really good experience in terms of working with all the different stakeholders in environment management,” he says, “from businesses and municipalities to state and federal governments.”

Still, though he found much of the work fairly interesting, Brian says the job mostly had the unintended effect of rekindling his interest in ecology and natural sciences—and therefore a desire to return to school.

So he then enrolled in a master’s program at San Francisco State University to study geography and natural resource management. “I went back to school to get back into ecology, and particularly forest ecology, and I did my thesis research on a post-fire study of the Point Reyes National Seashore.”

Resurveying an area that had burned in 1995, Brian was able to explore more than a decade of post-fire succession to see how the forest ecosystem had responded. “Those years at San Francisco State were when things really started to click for me,” he says. “I realized this was my dream job, to be able to combine research in forest ecology with teaching and mentoring.”

That revelation solidified his decision to continue on in graduate school for a Ph.D. Since he’d always been fascinated by the Yellowstone fires of 1988, he reached out to one of the pioneers of research in that area, Professor Monica Turner from the University of Wisconsin, and joined her lab to focus on forest disturbance ecology in the Northern Rockies. “That was sort of the next pinch-me-I’m-dreaming moment,” he says, “walking around in Yellowstone in the forests I’d seen as a kid go up in flames in 1988, and here I was getting to study this stuff for my Ph.D. It was unbelievable.”

While he was wrapping up his doctoral program in 2015—he had actually defended his dissertation in 2014 just before the birth of his son, who turned a year and half this August—he started looking for postdoc opportunities. He ended up applying to and getting selected for a prestigious Smith Conservation Research Fellowship, and he based his project at the University of Colorado Boulder.

Founded by Dr. David H. Smith, a pediatrician who developed a vaccine for childhood spinal meningitis and later became an active conservationist, Smith Fellowships support early-career scientists working in the field of conservation biology. The Society for Conservation Biology now runs the program, which brings in five fellows a year, provides funding for two years and allows them to design their own projects (SEFS Professor Josh Lawler was also a Smith Fellow from the class of 2004).

Professional training and development are also central elements of the program, as Smith Fellows attend three weeklong retreats a year. Traveling to different sites, they gain skills in everything from science communication and working with the media, to how to translate their research into successful environmental policy and management. “For me,” says Brian, “the Smith Fellows program has been a tremendous foundation for fulfilling my social contract as a scientist—making sure my research is not only broadening our understanding of the natural world, but also providing a solid foundation for informed decision-making.”

The core of the Smith Fellows program, of course, is the fellows’ proposed research project, and Brian has been looking at the phenomenon of subalpine fir decline in the Rocky Mountains. Largely overlooked since it never significantly factored into timber production, subalpine fir has suddenly gained prominence as some of its peers—especially lodgepole pine and spruce—have suffered extensively from bark beetle outbreaks. Mountain pine beetles and spruce beetles have killed trees across large tracts of forest, and Brian says a lot of research has identified subalpine fir has a critical stopgap species to keep habitat intact until the next generation of spruce and pine can establish. Yet now subalpine fir populations have also started to decline, so Brian is trying to figure out why that’s happening. “Resilience, or the capacity of forests to ‘bounce back’ after disturbance,” he says, “is critical for maintaining many of the ecosystem services we associate with forests—water supply, wildlife habitat, carbon storage and recreation opportunities.”

This research will keep Brian plenty busy through the fall and winter until he completes his fellowship, and then he’ll begin his move to Seattle. His official start date with SEFS is March 16, 2017, just in time for spring quarter—and he can’t wait to get here.

“As a forest ecologist, I can’t imagine a more exciting time to be in the Pacific Northwest,” he says. “You’ve got an enormous wealth of foundational forest ecology research from many of the folks at UW, and at the same time we’re starting to see the emergence of some really big changes in forests from wildfires and bark beetle outbreaks in the last several years.”

Brian sees a growing need to understand when, where and why these disturbances are happening, and to answer the critical question of how our forest ecosystems will respond. “A lot of my work focuses on understanding the mechanisms of resilience in these forests,” he says, “and then how processes play out across different spatial and temporal scales. Disturbances like fires and insect outbreaks are natural and important components of ‘normally’ functioning forests. At the same time, climate change and the associated steep increases in disturbance activity can trigger big changes in forests, setting different trajectories for decades to centuries.”

More broadly, Brian says he’s looking forward to connecting with graduate students and colleagues in the school and university, and collaborators and stakeholders across the Pacific Northwest. “The key theme in my research is looking at how forests change over space and time, and the role disturbance plays in those changes,” he says, “and I really like to use multiple approaches and tools to answer questions. That opens up a lot of opportunities to work with grad students who have a diverse skillset, and also to collaborate with folks across a broad spectrum of disciplines.”

We can’t wait to welcome Brian and his family to Seattle this spring, and to start harnessing his tremendous energy and ideas. “I absolutely love what I do,” he says, “and I’m excited to interact with folks who are as enthusiastic as I am!”

Taylor’s Checkerspot: An Endangered Butterfly with an Interesting Diet

Coming up on Monday, September 12, from 6:30 to 7:30 p.m., the UW Botanic Gardens is hosting a talk with one of our doctoral candidates, Nate Haan: “Taylor’s Checkerspot: An Endangered Butterfly with an Interesting Diet.”

2016_08_Nate HaanA member of Professor Jon Bakker’s lab, Nate studies interactions between plants and insects, and his dissertation focuses on the relationship between Taylor’s checkerspot butterfly and its larval host plants. Before beginning his doctoral research, Nate completed a bachelor’s degree in biology at Calvin College, and a master’s in natural resources and environment at the University of Michigan.

His talk will be held in the Douglas Classroom at the Center for Urban Horticulture. It’s free and open to the public, and you can RSVP in advance online, by phone (206.685.8033) or by email (you are also welcome to give a $5 donation at the door to help support educational programs at the UW Botanic Gardens).

About the Talk
Taylor’s checkerspot is an endangered butterfly that occurs only in prairies of the Pacific Northwest. Several agencies and nonprofits are involved in recovery efforts, which include habitat restoration and a captive rearing and release program.

There are several gaps in our knowledge of Taylor’s checkerspot that make recovery efforts difficult; we know especially little about how its caterpillars interact with the various host plants they eat. One of these hosts is a common native paintbrush, another is the federally threatened golden paintbrush, and the third is an invasive exotic weed!

Nate will share photographs and natural history of Taylor’s checkerspot and its host plants, and give an overview of his research projects and findings so far.

Hope you can make it!
