Perspective

When I was in high school, I spent a lot of my time in a nature preserve in my hometown. It was a tiny pocket of land containing a forest, lake, and bog. I spent hours there, running on the loop trail lost in my thoughts. I felt awestruck by how fearless the deer were of my presence and sat on the dock of the lake reading books and dreaming of my future adult life. I continued visiting the preserve throughout college, but things began to change. The environmental classes I was taking opened my eyes to things I hadn’t noticed before.

Before college, walking down the trail, I admired beautiful, colorful flowers dotting the forest floor. But after, I noticed all of the non-native species, the creeping periwinkle taking the place of native plants.

Before, I enjoyed the shade of towering trees. But after, I noticed all the saplings on the edges of the forest overtaking the rare bog plant community.

Before, I enjoyed the solitude the woods provided. But after, I knew about landscape fragmentation and noticed houses barely hidden by the thin layer of trees.

Before, I meandered along the raised boardwalk looking down at the mushy ground of the bog and jokingly feared that if I stepped off, I’d sink and be lost forever. But after, looking down, I noticed all the unique carnivorous plants sliced to their bases by weed trimmers used to maintain the trail I enjoyed.

Before, I was in the woods. But after, I was in a fragile nature preserve.

Now we wait

Doing research in the field requires a peculiar personality. As scientists, we have to be scrupulous and detail-oriented. We must take careful measurements and work hard to control the environment of our experiments. But the catch is that we also have to be able to live with outcomes that are beyond our control and care. When nature messes with our experiments in unpredictable ways, we have to let the consequences roll off our backs. Sometimes this means your plans are out the window, other times it means you have to redo a lot of work. But as a field researcher, you must remain adaptable under these imperfect conditions.

In looking back at the process of starting my field experiment this summer, I see it as a series of stages: site selection, data collection, plant transplant. Each stage had its own challenges. There was no manual for how to get through each stage successfully, nor any certainty that the problems I faced in a particular stage would even have solutions.

I can honestly say that I felt like I was kicked down a lot this field season. I would sit on the ground for a time thinking the worst had come, but always managed to stand and find a solution. When we finished our final transplant in mid-September, I felt a wave of happiness and pride.

On the day before I left Colorado, I went out to my sites one last time to take photos. I noticed a strange hole in a section of land we had just transplanted and eventually pieced together that it was perfectly hoof-shaped. The cows had started grazing on our sites.

I didn’t understand the implications of this for my experiment until I returned to Colorado this week and saw that over a third of my transplants had been heavily trampled to the point that I am unsure if the plants will survive.

After all of the effort it took to stand after each problem throughout the summer, the feeling of seeing my work literally trampled was horrible.

When I bring this up to others, I am told simply (and somewhat reassuringly) that this is how science and experimentation is. It is often messy and prone to mistakes since we are standing on the edge of what is currently known. It makes sense that trial and error are fundamental parts of the scientific process, but when I hear presentations or read publications, I don’t learn of these parts. Why?

Perhaps it is because failure isn’t rewarded in science. Even while standing over a cow trampled transplant, my first thought as a second year graduate student was: how will this impact my timeline and my ability to publish? Only after that thought did I realize that the trampling doesn’t diminish what I accomplished or learned this summer. If anything, it teaches me more about the realities of field research and how to do better science in the future (i.e., the point of grad school).

On my drive home from Colorado, I listened to a TED Talk podcast called “Failure is an Option.” Fitting, right? But the podcast reminded me that trial and error is not failure; trial and error is learning. Failure is continuing down a path you have learned is unsuccessful. And my trial and error has not yet led me to that conclusion.

So now, we wait. We wait until spring to see if the plants survive. My brain starts ticking forward with possible solutions, plans, and ideas if they don’t. But I quiet it and, for a little while, I’m happy to just pause and wait.

Update on transplant experiment

My field season at the Rocky Mountain Biological Laboratory in Gothic, Colorado is coming to a close. It has been an intense four months of fieldwork in order to start my first graduate-level experiment.

As predicted, this season has been full of the problem solving that comes with starting a field experiment. Last I wrote in June, I was just beginning to learn to extract square sections of land (which we call turfs) in order to transplant them down a mountain to study the effects of climate change.

After determining that the land wouldn't completely fall apart when extracted, we searched high and low for better tools for the job. When asking understandably skeptical hardware store employees about tools, I liked to describe the project as digging holes without disturbing the holes! It took months of turf extraction trial and error, but eventually we bought or invented all of the tools, boards, lifting mechanisms, etc that we needed to successfully extract a turf.

Framing the turf to make sure we cut it to the right size

Another major part of the summer was determining which locations to transplant turfs to and from. I listed my ideal site criteria and then relearned the lesson that fieldwork is never perfect! But my search did lead me to a brand new site where no one else at the research station is working, so we were fortunate enough to be able to name it ourselves after the strikingly beautiful Frasera speciosa or Monument plant.

Now the aspens are turning yellow and I am happy to write that I have collected ample baseline data on all of the turfs and successfully transplanted 30 (so far)! See the video below for a timelapse of the turf extraction and transplant process.

Attempting to move mountains

I am back in Colorado for another summer of fieldwork at the beautiful Rocky Mountain Biological Laboratory. This summer, I am excited to start an experiment of my own.

The climate is changing in the Rocky Mountains where I am working. Increasingly warmer temperatures are lowering the amount of winter snowpack and advancing the timing of spring snow melt. The ability to predict how plant communities respond to a changing climate is increasingly a central challenge and focus in biodiversity and ecological science. In order to recreate the conditions of a warmer, drier climate, I will be moving whole sections of plant communities down an elevation gradient (ok, not quite moving mountains...). I will then measure a variety of plant and community characteristics to assess changes to plant community composition and functioning.

One of the most immediate and potentially experiment-ending challenges will be to uproot intact sections of land and transplant them successfully to new locations. I have accepted that this is a risky project and I am trying to anticipate problems in order to minimize the risk. I have been practicing digging up sections of land with different soil types and plant species using a variety of tools and techniques. Though I have found variable success, I am hopeful that with more practice and strategy, this process will go smoothly. Pending that success, I will then have to wait a year to see if the transplanted plants survive and grow next summer.

Scientific publications often highlight stories of success: a ground-breaking experiment, observation, or theory. It is important to keep in mind, however, that prior to publication there was likely a lot of trial and error, learning and revising. Science is problem solving and I have a feeling that this is what my summer will be all about. Regardless of the success of the experiment, I am certain that by the end of the summer, I will have gained a greater understanding of what it is like to do field-based research. And likely some very muscular arms!

Our first attempt ended in a crumbled mess!

Attempt 2: Not bad, but too destructive to the surrounding plants.
Attempt 3: Our best yet. Time to move on to new types of plants!
Attempt 4: Struggling to remove a forb-dominated turf.
Attempt 5: Successfully removing a turf with bare ground. We're getting there!
