These boots are made for walking

This week, Dispatches from the Field welcomes guest blogger Sian Green, who shares some stories about her ‘fieldwork style’.  For more about Sian, check out her bio at the end of the post.

For my 21st birthday I wanted what all girls want…a new pair of shoes! I got my wish and, although they were somewhat lacking in heels and glitter, since then they have taken me all over the world and been an essential part of my fieldwork outfit for nearly 5 years now. When you’re on your feet and walking long distances day after day, a good, comfortable pair of boots can make a big difference!

My poor, finally beaten, boots.

My poor, finally beaten, boots.

My boots have travelled with me to Costa Rica, Tanzania and Kenya; however, sadly, during my last expedition to Romania, while trekking the Carpathian foothills in search of large mammals, they walked their last mile. Having been soaked in the dewy grass every morning then baked by the fierce Transylvanian summer sun every afternoon, they finally fell apart.

In memory of my favourite pair of shoes, I thought I would share some of the most memorable moments I had whilst wearing them out in the field.

Scariest moment: After graduating from my BSc in Zoology, I wanted to get some more field experience. I decided to volunteer on a project in Costa Rica, working in a remote camp in the jungle, right next to a turtle nesting beach. At night we would go out along the beach to monitor the turtles, recording condition and taking shell measurements, as well as marking locations of new nests. On one night we saw a turtle about to start digging her nest. Not wanting to disturb her at this crucial point, we walked on and spotted another turtle about 25 meters up the beach. She had finished laying her eggs, so we set to work measuring her shell. I should mention at this point that it is important to use minimal light, and only red light on torches, so as not to disturb the turtles, meaning visibility was limited. Anyway, having finished measuring our turtle, we turned back to see if the first turtle had finished her nest…only to find her carcass lying on the beach surrounded by large jaguar tracks! This silent hunter had made a kill a few metres away from us in the dark and was surely now watching us from the forest edge…possibly annoyed by having been disturbed from its dinner. Needless to say, we moved on quickly and kept in a tight group at a healthy distance from the forest edge after that!

Proudest moment: I am very proud of all the fieldwork I have done, in particular my work in Kenya I undertook as part of my own independent research project for my Masters thesis. Of course, I am proud of my thesis, but sometimes it’s the little things that really stick in your memory. To study the elephants using the Mount Kenya Elephant Corridor, I set up a grid of camera traps. I would regularly trek through the corridor to check the cameras, aided and guided by rangers from the Mount Kenya Trust. I am tremendously grateful to these extremely helpful rangers… but they were sometimes almost too helpful, insisting on doing all the climbing and retrieving of awkwardly-placed cameras. After a couple of expeditions, my confidence grew and I started to feel I needed to prove a point – that I could climb trees just as well as they could! At one point this did result in me being up a tree covered in biting ants while playing it cool and pretending I was totally fine – but mentally questioning whether it was worth it to prove my point! But one very satisfying moment came when a ranger was unable to unlock one of the padlocks attaching our camera to a tree. I asked if he wanted me to try but he said no and called over one of the other rangers, who also failed to get the key to budge. Ignoring me, they called over a third (male) ranger. While they were discussing the problem, I went over, gave the key a jiggle and the lock popped straight open! They were all very impressed and claimed that I must be very strong. I think it was more about technique than strength, but I wasn’t about to correct them!

Most rewarding moments: All surveys are important, even when you don’t find what you are looking for. In fact, the latter type of survey can sometimes be the most important, as if you don’t find what you are expecting it may indicate a decline in population, or lack of accurate understanding of a species’ biology. This is what I would explain to all the volunteers I led on large mammal surveys when working in Transylvania. However, there is no denying that it is hugely rewarding when your hours of trekking up steep slopes result in finding a beautiful trail of perfect brown bear prints, or when that early start results in getting to see your (normally elusive) study species. Working in Transylvania was incredible, as we found signs and got camera trap footage of many elusive mammals, including martens, badgers, foxes, wild boar, wildcat and brown bear – and I even got to see a brown bear!

This fieldwork was also particularly rewarding because I got to share my knowledge and experience with the volunteers that came out. Teaching camera trapping skills and seeing how excited everyone got when we checked the memory cards was a great feeling. Hopefully some of these volunteers will go on to use the knowledge further on their own fieldwork adventures – and hopefully they will remember to pack a good pair of shoes!

Sian completed her undergraduate degree in Zoology at the University of Reading and her Master’s by Research with the University of Southampton and Marwell Wildlife studying elephants in a wildlife corridor in Kenya. She loves to travel and explore new places – and if she gets to put up a few camera traps all the better! Her fieldwork has taken her to Costa Rica, South Africa, Tanzania, Kenya, and Romania; however, she is now back in Devon, UK looking to move on to a PhD and camera trapping any innocent animals that pass by!

The things we do…

My advisor has always maintained that a field crew runs on its stomach.  In other words, well-fed field assistants are much happier and much more productive – not to mention much less likely to mutiny.

There is no doubt that this is true.  Trying to run a field crew without an adequate supply of coffee, chocolate, or wine is an enterprise doomed to failure.  But – at the risk of disagreeing with my advisor – I would argue that food alone is not enough.

Spending time in the field often leads to awe-inspiring experiences, like the moment when you come face to face with a lynx or watch a fierce lightning storm at sea from the safety of a remote island.  But in between those moments, if we’re being honest, field work can be pretty tedious.

And if it’s tedious as a graduate student – when your entire thesis depends on the data you collect – it’s a hundred times more tedious for your assistants.  Field assistants are expected to work long hours, rain or shine, for weeks on end without a break.  So as a boss, keeping morale up can be a huge challenge, and when you have a chance to provide some fun for your assistants, you really have to take it.

And that, in a nutshell, is how I ended up lugging a dead beaver up a mountain.

 

Let’s back up a step, so I can set the scene.  It was the first field season of my PhD, and my field assistant and I had spent half of January driving across a large chunk of the continent, ending up at an old, somewhat isolated house in the southern Okanagan Valley.  The house was large, drafty, and empty, and our days were spent trekking through the snow and waiting around in the cold in a (largely futile) attempt to catch bluebirds.  Every night, we came home, made dinner, and then went to sleep.  It was not the kind of field work you write home about.

Our cozy field home in the Okanagan.

But my field assistant – being a nature-loving type – was prepared to make his own fun.  He had brought with him a game camera, which he intended to mount on a tree to take automatic motion capture pictures of the local wildlife.  During our first week in BC, he trekked up the mountain behind our house and spent hours looking for the perfect spot to leave it – hoping to capture a black bear or maybe even an elusive mountain lion.

Unfortunately, when he went back a week later, the camera had not taken a single photo.  Undaunted, he decided that the logical course of action was to use bait.  At first, he contented himself with scraps from our kitchen, hiking up the mountain regularly to drop them in front of the camera.  And indeed, the camera did capture photos of the occasional crow or raven checking out his offerings.  But no bear or cougar appeared, much to his disappointment.  He started talking about finding something better to bait the camera with.

And then – lo and behold – as we returned home one grey winter afternoon, he spotted the ‘perfect’ bait.  A dead beaver lay at the side of the road right beside our driveway, the clear victim of a fast-moving vehicle.

My field assistant was completely ecstatic, but I wasn’t entirely convinced: I couldn’t help but wonder if the sudden appearance of a beaver halfway up a mountain, several kilometers away from any water, might be more puzzling than enticing for any lurking bears or cougars.

But then I thought about how limited opportunities for fun had been so far.  And I thought about how excited he was.  And – against my better judgement – I found myself offering to help him lug the beaver up to his camera.

The first step was to wrestle the body into a garbage bag, to facilitate transport.  But this was not a small beaver, and coaxing it into the bag was…challenging.  By the time all of its limbs had been stuffed inside, I was sweating – and starting to regret my offer.

Then we started up the hill, each grasping one end of the bag.  It rapidly became apparent that beavers are not particularly light animals.  We staggered along, panting, the thin plastic slipping out of our awkward grasp frequently.

We hadn’t made it more than a few hundred yards before we concluded that another approach was required.  We decided the best approach was to take turns dragging the beaver.  Of course, the side of a mountain isn’t known for smooth passage, and the garbage bag – never particularly sturdy – became progressively more torn and tattered as we struggled towards our destination.  A paw appeared out one corner; a glimpse of tail was visible through another rip.

In the end, our gruesome task took us almost two hours.  I don’t think I’ve ever been so glad to drop something as I was to let go of that bag when we finally reached the camera.

And the result of all this work?  Well, as far as I can remember (although to be honest, I’ve tried pretty hard to block the memory out), the camera failed to capture a single animal coming to check out the beaver; indeed, when my assistant climbed the mountain a week later, the body was still completely undisturbed.

But hey.  At least I got to feel like a good boss.

Squirrel Chatter

This week on Dispatches from the Field, we welcome Sarah Westrick, a Ph. D. student at University of Michigan who shares her experiences at Squirrel Camp! For more about Sarah, check out her bio at the end of the post. 

As a biologist, I’m enamored with nature. Learning more about the natural world around us is what drew me to the field, and biological fieldwork provides some amazing opportunities for me to connect with the natural world. I am lucky to be participating in an incredible long-term field biology program as a third-year PhD student in Dr. Ben Dantzer’s lab at the University of Michigan.

The Kluane Red Squirrel Project (KRSP) is an active research program focused on understanding the ecology, evolution, behavior, and energetics of the North American red squirrel. Since 1987, when Dr. Stan Boutin at University of Alberta established the project, KRSP has grown into a large collaborative effort between the University of Alberta, McGill University, the University of Saskatchewan, the University of Guelph, and the University of Michigan.

“Squirrel Camp” is our field research site, located in the boreal forest along the Alaska Highway in the Shakwak Trench near Kluane National Park in the Yukon Territory, Canada. The boreal forest in this region has been studied since the 1970s by researchers on the Kluane Ecological Monitoring Project, including Dr. Boutin, and continues to be well studied by ecologists from all across Canada and the US.

Working at Squirrel Camp is an incredible experience for many different reasons. One of my favorite parts of doing fieldwork in this region is the chance to really get to know the land we live on and the ecosystem we work in. When you’re out in the forest every day, you learn about the plants and animals intimately. I believe one reason the boreal forest of the Yukon has been studied for so long is its ability to excite ecologists’ natural curiosity. Questions about the ecosystem can come quickly to an inquisitive mind wandering the area.

At Squirrel Camp, we have multiple active study grids in the forest. Each morning “squirrelers” head out to their respective grids to monitor the red squirrels living in that patch of forest. Although the grids become familiar old friends, each day when you go into the forest you never know exactly what you’re going to see. You may see arctic ground squirrels alarm calling, encounter goshawks hunting, or accidentally flush out a mother spruce grouse and her chicks.

This past summer was my third field season at Squirrel Camp. One day in July, I went out in the forest expecting to have an easy morning live-trapping my target squirrels. Each squirrel defends its own territory and can typically be trapped there, allowing us to monitor its reproductive status throughout the breeding season. Preoccupied by my thoughts, I moved between two of my trapping locations on autopilot, taking a trail well worn by many squirrelers past. As I neared my destination, I began to hear the familiar barking call of the red squirrel, a common sound in a forest with ~2 squirrels per ha.

Not giving it much thought, I continued down the trail. The barks got louder and more frequent. Multiple squirrels joined in the chorus. At this point, I was curious to see who could be causing such a racket and if it meant there was a shift in the red squirrel social neighborhood. My eyes searched the trees for the telltale wiggling branch of a spruce tree or a small furry red tail darting between branches, but I couldn’t find that search image. Instead, I found a much larger furry form in a tree about 10 m away: the long legs, tufted ears, and bob tail of a Canadian lynx. I stopped dead in my tracks, staring, and the lynx looked back at me, panting. We took each other’s measure. After a few seconds, with me fumbling for my camera, the lynx decided to move on and jumped out of the tree, trotting into the forest.

While seeing lynx from a distance is not uncommon in our forest in the winter, we hardly ever get near this cryptic predator in the summer, as they move with stealth and blend into the trees before we can see them. But while the stealthy lynx is difficult for us to see amidst the leaves and spruce needles, to a squirrel it’s critical to spot a lynx before it ambushes them.

After giving the lynx a few seconds to walk away, I approached the tree he was in and found one of our juvenile squirrels frozen atop a witch’s broom in the tree, having narrowly escaped becoming lunch for the lynx. In a nearby tree, his mom was responsible for part of the racket that had attracted my attention in the first place. She was still barking like mad and the neighbors were still in an uproar. It’s not often we squirrel researchers observe a predation event – or a near-miss – and I appreciated being privy to this part of the ecosystem that we rarely get to witness.

To top it off, this wasn’t just any random lynx in the boreal forest; this lynx had a blue tag in his right ear. A group of my colleagues at Squirrel Camp had trapped him the previous winter to tag and take a DNA sample. (Squirrel Camp is in fact a multi-purpose field camp: ss our “squirrel season” comes to a close each year in late fall, the Lynx Crew, as we affectionately refer to them – to differentiate them from the Hare Crew (studying snowshoe hares) – moves into camp to track the abundance and behavior of this elusive predator in the ecosystem.) This particular lynx had been followed through the winter farther west down the Alaska Highway, but had since made his way east to our squirrel study grid.

To me, this encounter was a reminder to savor the special moments in the forest while doing fieldwork. Even through the stressful, frustrating moments in the field, I can always find some part of the ecosystem to ground me. Not many people are fortunate enough to be in the forest often enough to develop such a connection to the land and the ecosystem. Now I walk the forest with open ears, listening closely to my squirrels, and open eyes, scanning the trees for surprises.

Why we need more than science

This week, Dispatches from the Field is excited to feature a guest post from Dr. Laura Coristine.  In her post, Laura shares a bit about her early passion for working with one of the most charismatic megafauna out there: wolves.  To learn more about Laura, check out her bio at the end of the post.

My passion for science started with wolves. As an 11 year old I read every book on the topic that I could find. I hadn’t yet heard of journal articles; back then, finding my way to a university and wading through the stacks would have been a two-hour metro ride, and who knows what I would have found. Suffice it to say, the world was not connected. There was no information at anyone’s fingertips, unless they sought to become an expert.

Fast forward to university: by third year I was desperately contacting every researcher in North America who had ever studied wolves. I sent e-mails. I mailed letters. I made long distance phone calls. It was a full-time job, and finally, impressed by my determination, a researcher put me in touch with Canada’s foremost wolf expert. I was hired for the summer.

When I showed up for my first day, I was told I would be learning the secrets of what wolves eat. I was enchanted, for a very brief moment. And then came reality.  “Do you know,” I was asked, “that wolves eat vegetation and berries?”. Of course, I knew. I had first read that fact as a child. I have to confess though, that for someone reputedly intelligent enough for academia, I was remarkably slow to connect the dots. But finally it clicked: I had been hired to study wolf dung.

The job, in a nutshell, involved teasing apart differences between what different species of wolves ate through the seasons. I was rinsing and sterilizing wolf scat until the particulate matter had washed down the drain (the janitor was called almost daily to deal with the clogs in the sink). And at the end of this process, I was left with a tangle of hairs from the wolves’ prey – rabbit, beaver, and the occasional deer or moose and the even more occasional berry. Although I must say identification of hairs was fun, the process, in a nutshell, stank.

Then there was the process of assessing wolf skull morphology to assess hybridization and species composition of wolf packs. I thought this was a step up from the fecal analyses…but it turns out we were boiling wolf heads – road kill and hunting remnants – in a vat until the meat fell off. I became vegetarian after that task.

But finally, as a reward for my patience with unappealing lab tasks, I was let loose into the field to sample wolf vocalizations for my honours project, which aimed to replicate a study conducted 30 years earlier. My supervisor was convinced that with better methodology and better sound recording equipment, we might see new results.

Through each night of August, I chased wolf packs and coyote-wolf hybrids across the Madawaska Plains of Ontario.  After staking out known pack territories during the day, my field assistant and I followed a rigorous protocol of night-time howling and waiting for wolves to respond.  I learned the crack and waver of a wolf call, the higher pitch of a coyote, and the excited yips of the youngest wolves.

The crowning moment of my field season, though, was the evening a small farming community invited us to a corn roast before letting us roam through a farmer’s field to collect our audio recordings.

It was a quiet night; my call raised only a single howl, rapidly swallowed by the inky dark of a rural night sky.  We waited.  And waited.  Waiting was not part of the protocol – we were supposed to move on, but we had been told that this was the place to find our wolves.

And then I jumped.  There, off to the side, was a flash of eyes, and then another.  Not a sound. But as I turned slowly in a circle, I realized that we were surrounded on all sides.  Breath catching, we were held immobile by a circle of glowing wolf eyes.

There is a tension between human and nature – at least for a human who has not grown up completely inside of nature.  My mind turned to Jack London’s Call of the Wild and White Fang, to Russian folktales of wolves chasing man, human fear warring with the scientific fact that no healthy wild wolf in North America had ever killed a human.  And then I howled, and the wolves howled back: long, wavering calls that rose and broke in a symphony of nature, until slowly, gradually, the wolves quieted and watched us.  Long moments of looking at each other across the farmer’s field, silence stretching out to eternity before their eyes winked out and disappeared.

At the end of the summer, I was asked to return for a Master’s.  Despite the scat and the boiled skulls, the entire summer had been one of the most amazing educational experiences of my life. But I didn’t know how to break the news: science had already collected so much information on wolf ecology – what was left to discover? I couldn’t see myself returning for graduate studies to continue studying what we already knew.

Wolves, like many large mammals, are under threat from climate change, from habitat loss, and from human fear and persecution.  Wolf ecology, behavior, and diet are well known, well established.  When I was asked to return, I realized that sometimes it isn’t a matter of learning more about a species.  Instead, it is a matter of using the information we have to change policies and decisions about nature.

Sneak Preview of “Bats of Ontario”

This week Dispatches from the Field is excited to welcome back Toby J. Thorne, who wants to share with you a sneak peak into the “Bats of Ontario” field guide he wrote. Check out the end of the post for where to purchase it!

Most field biologists will consult a field guide at some point in their careers. Whatever critters you’re studying, it helps to know what they look like, along with basic characteristics or measurements! Certainly I have accumulated my own small collection of field guides over the years. Field guides are exciting: filled with aspiration, and the promise of new adventures and discoveries. They are also working books. A true field guide is intended to be well thumbed, stuffed into packs, and referenced in all weathers.

But despite my love of field guides, I never gave much thought to where they come from. At least, not until someone suggested I write one.

For the past few years I have volunteered with the Matt Holder Environmental Education Fund. Founded by Phill and Sue Holder, the fund is in memory of their son Matt, a keen naturalist who died unexpectedly young. The fund’s goal is to provide opportunities for young people to get involved in nature, and Phill hopes to support the fund through the sale of field guides. To this end, he produces a range of well put-together guides. To date these include books on birds and moths in Southern Ontario, along with several checklists for Thickson’s Woods in Whitby, where the fund’s activities are centered. When he suggested I should write one for bats in Ontario I couldn’t say no!

A good guidebook is important when working with bats. In the tropics there can be hundreds of species, many of them understudied. In more temperate regions such as Canada, there are fewer species – for example, Ontario is home to just eight. Yet while there are not many species to learn for Ontario, figuring out how to tell them apart can be quite tricky. To add further confusion, there are two distinct identification methods for bats.

One way is to catch them and have a close up look. This works most of the time (if you have the appropriate skills and permits to do so), but sometimes it’s easier said than done. I have previously caught two species of European bats whose key differences are a tiny tooth cusp and penis shape. The second of those is only useful about half the time!

The second way to identify bats is to monitor them acoustically. Due to the difficulty and invasiveness of catching them, this is often the preferred method. Acoustic monitoring involves listening to the echolocation calls bats make during flight. The calls allow us to determine where bats are, and get a relative measure of bat activity. We can also try to differentiate between species of bat by their differing calls.

In practice, using calls to identify species is not simple. Bat echolocation calls depend on an individual’s environment and what it is doing. This means that different species of bats that are doing similar things can sound similar.  Also, to make it more confusing, the same bat can sound quite different depending on what it is doing!

These difficulties keep life interesting when you’re trying to ID bats, and made assembling a field guide seem like an attractive challenge. When I started, there was an excellent earlier guide still available, but at ten years old it is a little out of date on a few things, so producing my own guide was also an excellent opportunity to share some more up-to- date information.

An initial problem (and the one that worried me the most), was assembling suitable illustrations. Most of my own photo collection is of UK species, as that was where I first learned about bats before moving to Canada for my MSc. Since arriving in Canada I’ve managed to photograph some species, but not them all.

Luckily, Phill came up trumps on this front. He was able to negotiate the use of artwork by Fiona Reid, an incredible wildlife artist, for the guide. Fiona is the author and illustrator of the Peterson Guide to Mammals of North America. Phill has set the layout of the book around life size reproductions of Fiona’s illustration of each species, and the use of her artwork has elevated the book to something much better than I could have hoped.

Once Fiona had agreed to contribute her illustrations, I really started to feel the pressure to match her efforts with equal effort of my own! Over the past few years, living in Ontario and working with bats, I have become familiar with the local bat species. However, writing the species descriptions for the guide called for some research. It was necessary to fill in a few gaps and check for knowledge I’d not come across. Also, this was an opportunity to check the things I already ‘knew’. It’s always good to question ourselves!

While species accounts are the key parts of a guide, I found that I also enjoyed writing the introductory sections, which included background information about bats. There are also several sections aimed at beginners interested in learning how to watch bats.

Overall, producing the book has been a great experience, and I learned a lot in the process. It is great to have the chance to share that knowledge and hopefully encourage more interest in these amazing animals! Currently, bats are facing several worrying conservation threats (particularly in North America), and they need all the friends they can get!

Toby caught his first bat at the age of eleven, and has been chasing them every since. After spending his teenage years catching and learning about bats in the UK and completed an undergraduate degree in Biology at the University of Oxford. He moved to Canada in 2013 to undertake a researcher masters supervised by renowned bat researcher Dr. Brock Fenton. Since graduating he has continued to work on bat projects, and currently divides his time between the Ontario Land Trust Alliance and the Toronto Zoo, where he is spearheading the Zoo’s Native Bat Conservation Program.

The Challenges of Tracking a Ghost Cat

This week Dispatches from the Field welcomes Katey Duffey, a researcher who shares the hardships and rewards of searching for snow leopards. Check out her bio and website at the end of the post!

Sitting on a mountaintop, feeling the chilly crisp air, my senses absorb the environment that I think of as my second home. Yet it couldn’t be any more different from the flat, cornfield-covered state of Ohio where I grew up and currently live. The region is almost eerily quiet except for the occasional clucking of a chukar partridge echoing from somewhere nearby, and seems barren and devoid of life. The only movement is the gentle sway of a tuft of brown grass clinging to its existence on the shallow rocky substrate between boulders. A cloudless blue sky appears to reach down and embrace the endless horizon as the earth sparkles below. This is the very definition of remote wilderness: a place where the environment is as dangerous as it is beautiful. It’s an environment with many risks and many challenges. While other mountaineers explore the peaks of mountains for sport or a personal goal, I have a different purpose….to find snow leopards.

The snow leopard is quite difficult to study. There is still so much unknown about them and I often hear people ask why that is the case when snow leopards are such a charismatic animal. They should have no problem acquiring scientific attention. But they are solitary and elusive within their huge home ranges: 220km for males and 130km for females. Those who study them rarely, if ever, even glimpse one outside of a camera trap image. However, it’s their habitat that really makes this endangered big cat a challenge to monitor.

Snow leopard

Snow leopards are found in the mountains of the Himalayas and the Tibetan Plateau at elevations ranging from 3,000 to 5,000m. Their range overlaps boundaries of 12 countries. The area is as remote as you can get for a field site and the rugged terrain makes possible survey areas inaccessible. Over the past few years, I’ve gotten to my transects via a Russian Soviet era van, jeep or a motorbike. Some areas even require getting there by horse.

Having fun collecting scat.

Once I’ve managed to access a site, I then begin to survey the area for signs of snow leopards: hiking, climbing, and wishing the golden eagles I see were large enough to ride, like the Great Eagles in Lord of the Rings. When I’m looking up the slope of a mountain to scout a route to survey for snow leopard signs, some terrain features stand out as the best potential places for tracks, scat, scrapes, and urine spray. These key features include rocky outcrops, cliffs, rock walls, steep slopes covered in thick scree (loose rocks), and narrow ledges. But the question that usually pops into my mind is: “Where is the most technical section that would be the biggest pain in the rear to get to?” Because that’s where I’m going to find snow leopard signs.

Valleys, draws, and saddles are other mountain features where signs can often be found, since snow leopards use those as a relatively easy path to patrol and leave their territorial marks. If I see a big, rocky outcrop on a super steep slope, I’ll use a nearby draw (a sloped indent in the mountain that travels from the base to the top) to hike up, and then cut across a less precarious way. Doing so saves energy, saves time, and more importantly is much safer than taking my chances with a rockslide or ice. If you get your leg caught by a falling boulder or get injured on ice, your field season is not going to end well.

Winter and early spring are the best seasons for tracking snow leopards. This is the time of year when the cats are more active as they mate and get ready to raise cubs. Snow helps to locate tracks and fresh scat, while frozen rivers become roads allowing deeper access into valleys.van stuck in the snow A bonus is that the snow makes hiking down slopes more fun, since you can carefully “ski” down and will also have a softer landing if you humiliate yourself with an ill-placed step. However, in places with deep snow that comes up past your knees or to your waist, you become envious of the tracks of a cat with snowshoe-like paws. Deep snow is a problem for field vehicles as well and often turns into a delay that cuts into precious, limited daylight hiking time.

While staying in snow leopard country during winter seasons, my team stays in either our own ger* or with host families. There is no plumbing, no electricity (except what we can get from a car battery), and no Wi-Fi. I’m usually with maybe one other person who speaks English. Add being immersed in a traditional culture completely different from that of most “westerners”, and the thought of doing this type of work seems almost alien. The job can be lonely, despite being around many locals during home visits. Living conditions include exposure to dirt from livestock, unpasteurized dairy and raw meat contaminating surfaces in homes. On top of that, the ventilation in homes is poor, so you’re constantly trying not to choke on smoke, while in close quarters with strangers who are often ill. In other words, your immune system gets a workout!

Another challenge of winter fieldwork in snow leopard country is the extreme cold. Average daytime temperatures range between -15˚ and -30˚ Celsius. While hiking transects, it is important to wear warm, breathable layers. The lowest temperature I experienced was a nighttime temperature of -50˚ Celsius (with added wind chill)! If you can’t fathom what that feels like, imagine an industrial freezer filled with dry ice.

Needless to say, toilet trips outside are avoided as much as possible (This is when being a woman is quite inconvenient.) The cold also makes camp life a bit more difficult. Everything is frozen, including the firewood and livestock dung. Your water comes from boiled snow or ice and food needs to be set near the stove to thaw. While waiting for that to happen, I usually spend some time doing some warm-up exercises to get the circulation going in my frozen digits.

The climate and environment are treacherous, the landscape pretty much looks the same in all directions, wildlife is not often seen, and I frequently question if I even belong out there. However, it’s those challenges that drew me to this work, and they give me a sense of purpose. Rewards come in many different forms. On my last trip in March, a teammate and I were rewarded by a glimpse of a ghost cat leaping across boulders before disappearing. That sight in and of itself was more than enough reason to endure the hardships (or abuse) of this remote fieldwork.

Her research focuses on the effects of livestock depredation by snow leopards, and the potential for transmission of zoonoses from livestock to snow leopards. Although her work has been in western Mongolia, she is always looking for opportunities to expand her projects to other countries in the snow leopard range or work with other carnivores.

The bear necessities

Anyone who has been following my posts has probably figured out by now that I am essentially a scaredy-Cat.  I love being in the field, but when I’m there, I worry about anything and everything – from mountain lions all the way down to cows.  Unsurprisingly, bears have always featured pretty high on my list of worries.  Huge, powerful bodies, sharp teeth, and a distinct tendency to be irritable when surprised…what’s not to love?

My initial bear encounter took place during my very first field season, up the Queen’s University Biological Station – and, in fact, wasn’t an actual encounter at all.  I was working at the station as a field assistant, and my duties included daily inspections of approximately 200 tree swallow nest boxes.  One day, as I made my way through a grid of boxes, I suddenly realized that one was missing.  At first, I wondered if I was losing it: how could a nest box just vanish?  However, closer inspection revealed that the box was actually still there…in pieces on the ground.  The nest was torn apart, the nestlings were gone, and a pile of bear scat sat on the ground close to the wreckage.

Until that point, I had thought of QUBS as an entirely safe place to do fieldwork.  Finding the ruins of that box was a rude awakening.  I froze in place and stared frantically around the field, looking for other indications that a bear had been there – or, more problematically, was still there.

In the end, of course, I found nothing; the bear that had destroyed the box was long gone.  In fact, over the course of my two summers at QUBS, I never actually saw a bear, just heard occasional second- or third-hand stories of sightings.  I eventually accepted that I was highly unlikely to actually meet a bear at QUBS, and I relaxed.

All that changed when I started my PhD.  I was thrilled to be doing my fieldwork in the beautiful Okanagan Valley of British Columbia…but at the same time, my mind heard the word “mountains” and interpreted it as “bear country”.  And while no one would claim the Okanagan is overrun by bears, my research informed me that black bears are reasonably common there, and even grizzlies aren’t unheard of.  Too make matters worse, a lot of my work took place in vineyards, where bears can be a big problem in late summer, when they come down out of the hills to gorge themselves on the grapes.

In preparation for this ‘highly dangerous’ fieldwork, I purchased a plethora of bear bells (to warn bears people were coming) and a few cans of bear spray (to deal with bears that didn’t heed the warning).  Armed with these tools (and accompanied by a ceaseless jingling), I felt pretty secure wandering around my field sites.  That is, until one day, when a local asked me, “How do you tell the difference between black bear scat and grizzly bear scat?”

“I don’t know,” I said innocently.  “How do you tell the difference?”

“Well, black bear scat is full of berries.  And grizzly bear scat…well, it smells like pepper spray and jingles a bit when you kick it.”

With a wicked smile, he went on his way.  I stared foolishly after him, clutching my pepper spray while my backpack jingled faintly.

This conversation somewhat eroded my faith in my bear spray and bells.  On top of that, it turns out that ceaseless jingling is phenomenally annoying after a few days.  Add to that the fact that I kept accidentally leaving my bear spray behind in various locations (forcing me to spend additional time wandering around in bear country attempting to retrieve it) and it’s not hard to understand why I decided to abandon that approach.

But I was still not enthusiastic about encountering a surprised, irritable bear.  So I devised a new strategy: I would just talk to myself as I wandered the hills, providing fair warning to any bear in earshot.

However, I quickly found out that it’s hard to talk constantly when you don’t have anything in particular to say.  In desperation, I found myself thinking back to high school, trying to recall any lines of the poetry or prose we’d recited in English class.  As it turns out, the only thing I remembered was the prologue to Romeo and Juliet.  So day after day, I would stumble around the Okanagan back country, repeating “Two households both alike in dignity / In fair Verona where we lay our scene…” as loudly as possible.  It’s probably a good thing that I didn’t encounter too many people on my wanderings.  At least the bears of the Okanagan are now well educated.

I guess the star crossed lovers did the trick, because I didn’t actually see any bears for most of my first field season.  But one day in early August, as I was making my way back to the car in one of my most isolated field sites, I rounded a corner and found myself about a hundred feet from a black bear.

Given that I’d worried about this exact scenario all summer, I was surprisingly taken aback. I turned on my heel and started walking away briskly, trying not to look back over my shoulder.  Finally, though, I just had to know.  I whipped around to survey where the bear had been…only to realize it had vanished.  Now I had a new problem: there was definitely a bear in my immediate vicinity, but I no longer had any idea where it was, and it was a very long walk back to the car.

Can you spot the bear in this picture?… Nope, I can’t either.

Clearly the thing to do was keep talking to avoid surprising it; unfortunately, though, Romeo and Juliet deserted me in my panic.  So I decided that the logical thing to do was call home and talk to my parents.

When I dialed my home number, my sister picked up.  I told her about the bear and explained that I just needed to stay on the phone to keep talking.  “That’s too bad,” she said impatiently.  “But I need to call my friend now.  Call Mum on her cell instead.”

Right.

I hung up with her, and did as she suggested, still striding in the direction of the car while swiveling my head vigilantly in all directions. This time, I managed to get a hold of my mum…and that’s when I learned that you never, ever, ever call your mother and tell her that you’re in the middle of nowhere, with an unseen but very real bear lurking around.  She was quite willing to stay on the phone with me, but had no problem letting me know that she was not thrilled with the situation overall.

Much to our mutual relief, I made it to the car with no problems, and I didn’t see another bear for the rest of the field season.  In fact, it was over a year before my next bear encounter.  This second run-in happened at a less isolated site, but played out in much the same way as the first.  I froze briefly, then did an about face and walked away.  And once again, after a few seconds, I couldn’t help glancing over my shoulder.  This time, the bear was still visible.  In fact, it looked an awful lot like he had also done an about face and was hurrying in the opposite direction as fast as his furry paws could take him.

Apparently some bears are aware that humans also have a distinct tendency to be irritable when surprised.
