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 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!

Tales of Turtles In New York City

This week, Dispatches from the Field is excited to welcome Rebecca Czaja, a recent graduate, to share her fieldwork story from her Masters project studying turtles in New York City (yes you heard her!). Check out the end of the post for more about Rebecca!

Turtles in New York City? That’s the reaction I usually get when I explain my Masters research project. I worked with the Jamaica Bay Terrapin Research Project, which has been studying diamondback terrapins at Jamaica Bay Wildlife Refuge (JBWR) for almost 20 years. JBWR, which sits on the border between Queens and Brooklyn, is not only the nesting site for hundreds of terrapins but also an important habitat for migratory and resident birds, insects, and other reptiles.

As part of a long term monitoring and conservation project, I was responsible for finding nesting terrapins, which are then collected to gather data such as weight and shell length. In addition, a protective cage is placed over the nests to prevent predation. Finding a nesting terrapin without scaring her off the nest requires a little bit of skill, good eyes (or binoculars), and a lot of luck. While a few terrapins are bold enough to nest right at your feet, most will abandon their attempt to nest if they see you. I can’t count the number of times I’ve found myself tiptoeing through thorny rose bushes or carefully kneeling in a field of poison ivy just to hide from a terrapin. The key is to stay out of sight until she’s laid her eggs, at which point she’ll finish burying the eggs even if you get too close for comfort. How do you know she’s done laying her eggs? She does a little dance. As she pushes dirt into the hole and pats it down, she appears to be doing a jig.

For my project, I focused on studying how precipitation impacts whether terrapin nests get eaten by raccoons. In addition to monitoring unprotected, natural nests for signs of predation, I also built and monitored over 200 artificial nests.

There are a bunch of possible ways to build artificial nests. I picked the simplest method: dig a small hole and fill it back up. Even without any eggs or terrapin scent, raccoons were attracted to these nests. I also tried filling nests with terrapin-scented sand, which was made by putting a terrapin in a box full of sand for at least 20 minutes. Unfortunately, getting the sand to smell just enough like a natural nest is an imprecise science. The terrapin-scented artificial nests ended up smelling so strongly that raccoons tried to predate every single nest, rain or shine. But the beauty of science is you live and you learn. So I stuck with artificial nests filled with plain old sand.

Ecology is the art of doing meaningful science with the simplest materials. My rain gauges were made from plastic bottles washed up onshore, duct tape, and sticks.

Doing research that depends on it raining at just the right time is nerve-wracking, to say the least. The month of June was unusually dry this summer, which left me constantly worried that I’d never get enough rain to finish the project. Especially because I not only needed it to rain, but to rain on a day when I had found a nesting terrapin. The first time it rained on a day when I had natural nests, I was ecstatic. The rain was unexpected, so I only had about an hour’s warning to hurry almost 1.5 miles across the park to place rain gauges at my nests. Fueled by my excitement, I got the rain gauges installed just in time. Of course, on the walk back I got soaked by the downpour and was chased by a Canada goose, but nothing was going to spoil my day!

 

Terrapin nesting season lasts about two months at JBWR, and then come the hatchlings. Yes, they’re as cute as you’re imagining. Just like adult females, hatchlings are measured and weighed. I then cut out a small piece from the edge of their shell in a specific location so that if they’re recaptured as adults, we’ll know what year they hatched. The piece of shell will also be used for DNA analysis. Hatchlings are then released near their nest, where they either run for cover in some vegetation or make a break for the water. All we can do from that point on is hope we see them again when the females are old enough to nest!

It’s amazing to think that less than a year ago I didn’t even know there were turtles in New York City. My Masters project taught me a lot: beach trash has endless uses, rain is unpredictable, and terrapins are much faster on land than you expect. But most importantly it reminded me each and every day of nature’s resilience. Watching a new cohort of terrapins hatch and make their way into Jamaica Bay’s marshes, despite pollution and habitat destruction, makes me optimistic that there’s still time to protect mother nature’s invaluable resources and beauty.
