Understanding our values of nature

Above: a view from the Lägern forest outside of Baden, Switzerland, one of the research sites for Katie Horgan’s PhD work. I ran the Lägern ridge while I was training for a marathon this fall.

I’ve always been interested in conservation. Okay, maybe in the beginning it wasn’t a choice. My mother worked for (and now runs) a land conservation nonprofit, and I grew up kicking around the office and volunteering at events.

Some of my first research and jobs in ecology were about topics related to global change: invasive species, contamination, climate change. I was motivated to take these jobs because I cared about the issues and thought that doing research related to them would help.

But these projects were all very much ecology. The grants weren’t written and the studies weren’t designed with an outcome in mind that could be translated to stakeholders or implemented as policy. They were pure basic science: what is happening? Hey, that’s cool (or alarming, or boring, or …. ), and it’s good that we know it now!

Even though so many of our ecology results are framed in the context of global change, including sentences and maybe even paragraphs talking about implications for land management, I’ve never studied conservation biology. Neither have most of my collaborators.

Recently, I have begun to understand how my good intentions and environmentalism don’t help the environment that much. I’ve been doing ecology in a vacuum: I care about “issues”, but those issues are separate from my science (even if they are merged on my Twitter feed). I really like community ecology and understanding species interactions, and that’s what drives my research questions.

I’m not sure that in and of itself is problematic. But what is certainly problematic is the extent to which I didn’t realize what I was doing. It’s hard to expect your science to connect to and inform conservation and planning if you don’t really understand conservation and planning.

One of the things that made me more cognizant of this was the defense of a fellow University of Zurich PhD student, Katie Horgan, last week. Katie’s dissertation was highly interdisciplinary, and it exploded my conceptions of how we think about nature and ecosystems.

Embarrassingly, the big thing that I realized should be obvious: how we value nature depends more on us, than on nature.

(That might seem like a bit of a jump from my first few paragraphs, but I promise I will link it together at the end.)

When I write out my “big realization”, it looks stupid. I find myself thinking that I already knew that. I interact with people every day who think about the outdoors in a different way than I do.

My boyfriend illustrates this perfectly. When I go for a long run, I want to go somewhere new and see a new view. Steve? He would be happy running exactly the same loop around Uetliberg, the local ridge, that he ran the previous week.

“Why do you need to take the train for two hours?” he asks me. “It’s still just a forest.”

The value we place on seeing and experiencing ecosystems is completely different. Running around in the same forest, or similar forests, we pick up different things and take away different experiences.

How does that relate to ecology? In the past few decades, there has been a push to quantify the value of the natural world. We call them ecosystem services – things like clean water, clean air, the provision of fish to eat and wood to build with, nice places to go recreate in. All of these things can be assigned a dollar value and deemed “natural capital.”

This approach can then be used to make policies protecting natural areas. Asking people to identify what is valuable in their landscape helps set conservation priorities. This approach can also demonstrate that neglecting such protection would be economically costly. In some places the ecosystem services approach has worked great, and in others not so much.

Until last week, I have to admit that I kind of saw ecosystem services as black and white: this ecosystem either provides this service, or it doesn’t. This forest provides X and Y. That lake provides X and Z. I saw ecosystem services as something you could measure objectively.

Then I walked into Katie’s defense.

Katie’s research is fascinating. She worked at eight different research sites scattered around the world, from two right here in northeast Switzerland to those in Siberia and Borneo. At each site, she asked people who worked at the conservation areas a series of questions: did they think that ecosystem service X was being provided by this area? What about ecosystem service Y?

This is a seemingly simple dataset and study, but the work and the results are far from simple. Just getting the interview responses, despite cultural and language barriers and all the rest, was a huge feat.

The thing that struck me most from Katie’s talk was that even in ecosystems that seemed in some ways similar – and actually, even at the same ecosystem– the people Katie interviewed had different answers about whether an ecosystem service was provided or not.

In other words: assessing what ecosystem services are provided does depend on the ecosystem. It depends on how people see the ecosystem.

Katie also mined through the responses and deduced how people thought about the value of these conservation areas. Rather than thinking only about an ecosystem service, she classified the responses by what this service corresponded to.

Did people see the service provided as something more utilitarian (“instrumental”)?

Or did they value this service differently, in a more “intrinsic” way – is the service provided something more fundamental, like biodiversity, that just is?

The third type of value is the one that makes me go run in a new place whenever I can – “relational” value, defined by the way that we interact with nature.

Different ecosystem services, which are the metric by which we turn nature into “natural capital”, were valued in a wide range of ways. And importantly, nearly every ecosystem service that Katie asked about was valued in each of the three ways by at least one study participant. In fact, most participants places more than one value on a given service!

Katie’s big question was, what are the things that motivate people to take positive action about biodiversity?

I had been thinking, like a cold scientist, that the natural capital of an area or ecosystem was defined by the ecosystem itself: the biodiversity contained within, the black and white ecosystem services it provided. I thought we had to convince people of that value, and then they would be motivated to protect it.

What Katie illustrated so powerfully was that actually, the value of nature is defined by the people valuing that nature. If we don’t recognize that, then we won’t really succeed with protected areas and conservation policymaking.

And because of that, it’s a little bit stupid for someone like me who leaves human interaction completely out of my research to put in pompous statements about how that same research will inform conservation.

A few days later, I saw the following tweet from Andy Gonzalez, from a presentation by University of Vermont professor Taylor Ricketts at a science conference in Quebec. It distills this point in a different, perfect way.

I bet I’m not the only ecologist who needs to mull over that message.

We live and we learn, and I’m trying to become a better scientist and a better person all the time. Part of that is being humble and realizing when you’re being clumsy or just kind of an idiot.

Hearing from inspirational colleagues definitely helps in that process.

Trail marathon / PhD marathon

This autumn I ground away at two big goals: finishing my dissertation, and running my first trail marathon. A number of people told me I was insane to try to do both of these things at the same time. But everyone has different ways of staying happy and maximizing what they are capable of. For me, it’s essential to have more than one thing to focus on. I have a few friends who must live like I do: they said, oh, that’s perfect! The last few months of dissertation writing were really hard. Although I made a plan with my supervisor about how to get everything done, work didn’t really proceed according to plan. Some things took longer. Other tasks required waiting on collaborators for feedback. Sometimes I simply realized that I had no idea what was expected as a certain output. I tried to start working anyway, only to…

Autumn in the Engadin

I love shoulder season in the mountains. Autumn is incredibly beautiful, but for a lot of alpine resorts, it is the slow time of year. Business owners take a break before the winter tourism rush begins. Kids are back in school, so the summer vacationers are long gone. Maybe it rains a lot. In many senses it’s an in-between. And yet: the mountains are still there. The days where it doesn’t rain can bring the most glorious blue skies. The plants start turning pretty colors, mostly reds and yellows. The highest peaks start accumulating snow. The weather is cooler, and as a person who suffers greatly in even moderate heat, that sure brings a smile to my face. It allows me to play outside for longer. Fall is a great time for the budget traveler, because it’s not high season (except if you’re headed to leaf-peeping land….) and rates are…

Seven More Routes on my Swiss Hiking/Trail Running Guide

I haven’t been blogging this summer, and for that I’m sorry. It has been busy, but when hasn’t it been? Anyway, maybe I didn’t write at the time, but you can still take advantage of all the adventures I’ve been having. I added seven new routes to my Swiss Hiking & Trail Running Guide, based on the favorite spots I went this year so far. I still have a few long runs planned for the fall, so the guide could see one more update before I leave the country after defending my PhD this winter. Click here for the guide. The new routes: Schwyzer Hohenweg from Brunni to Einsiedeln: Innerthal to Ziegelbrucke over Schwarzenegg and Scheidegg: Maderanertal Höhenweg: Glattgrat on the way from Klewenalp to Urnersee: Glattalpsee, from Bisisthal to Braunwald: Glaubenberg to Glaubenbielen and into the Marienthal (pic by Annie Chalifour): Trans Swiss Trail from Lugano to Morcote (pic by Steve…

Bye for now, Holmenkollen

A few weeks ago I headed to Oslo for the last* World Cup biathlon races of the season. I had some serious flip-flopping about whether to go or not: FasterSkier didn’t cover the trip financially, but I wanted to go see the races, I wanted to get away from PhD work for a few days, I wanted to go ski in the Nordmarka, I wanted to have one last hurrah. But it was expensive! Norway always is, especially last-minute. After lots of soul-searching and budget-considering, I bought a plane ticket, got accredited for the races, and arranged an AirBnB. As soon as I arrived, I knew I had made the right call. In mid March the days are already starting to get longer in Scandinavia. I arrived in the late afternoon and went for a jog in the evening light, skidding around on icy paths and sidewalks. Then I made…

Seiser Alm and perfect ski vacations

I’m seriously late with this trip report, but no matter. I want to tell you about a trip I took back in early February. Earlier this winter, when I realized that I was not going to the Olympics and thus had more time to play with in Europe (ha! only kind of! I need to finish my dissertation!), I asked on Facebook: what were my friends’ favorite places to cross-country ski in Europe? Places that I shouldn’t leave next fall without having visited? Yes, I am in that mode. I anticipate defending my PhD in September, which means that I am looking for postdoc positions and in all likelihood I’ll be headed back to North America. It’s not that I’ll never take another ski trip in Europe, of course, but doing so will be a lot harder once I’m based on a different continent. There is such a world to…

2017 Was a Year of Reading, or, What I Do To Escape Reality….

Last year, I made a resolution to try to read more. I did it because I really love reading, but I realized that I wasn’t doing so much of it outside of work. I wanted my New Years resolution not to be something that was a responsibility or a chore, but something that would increase the time I spent doing something that I liked. Something that would improve my quality of life and bring me some happiness. So: I resolved to read 52 books. One a week. And, dear reader, I did it! This might be the first time that I can say I hands-down nailed a resolution and kept it going all year long. I read 20,300 pages in print, aside from papers read for work or things read online (which is a lot; after all, one of the reasons for this resolution was to spend less time staring…

Haute Savoie and the Best World Cup Yet?

France has its own way about many things, and the Biathlon World Cup turns out to be one of them. The recent weekend of competitions in Le Grand Bornand was one of the most fun, atmospheric, and exciting events I’ve been to, although I’ve struggled to explain in words exactly what made it different. “I could go for the greatest skiing right from the venue!” Yeah, but I also had amazing ski adventures in Norway, Austria, and Germany. “The crowd was so huge, and so energetic!” Yeah, but see also, Ruhpolding and Holmenkollen, not to mention the Czech Republic for 2013 World Championships. You begin to see the problem. It was different all right, but is there a word for how? But whatever it was, which I will try nevertheless to articulate, it was amazing. Not only the races, but also everything else I did while there: the extra day…

My guide to hiking/trail running in Eastern Switzerland!

Note to FasterSkier readers: A different version of this page, on my website, will be updated as I continue running and hiking in Switzerland. You could check there for new suggestions in the future. First, a disclaimer: I’m just listing places that I have actually hiked: the 22 routes and areas which I found to be the most beautiful and remarkable, the most worth it for their relative travel times from Zurich. I’m in no way implying that they are better hikes than places I haven’t hiked! There’s more or less infinite trails to explore in this country and oh so many I haven’t gotten to yet. This list is focused primarily on Eastern Switzerland accessible from Zurich, although I couldn’t help from including some of my favorite hikes around Davos from the time I was living there. If you want to find routes in Western Switzerland, you’ll have to…

ugly/pretty.

If you look at the photo above, maybe you will not notice anything amiss. Maybe the thing that jumps out is the cut on my right leg. But actually, if you look at my ankles, you’ll see the left one is bulging out like crazy. I later found out, this is what it looks like when you slip on some mud, fall, and tear two ligaments in your ankle trail running, and then you cinch your shoes up real tight and say “I can do this, I’m probably overreacting”, run 10 more kilometers, begin to be in really excruciating pain, attempt to hitchhike without success, and then walk five more kilometers over uneven ground down to the nearest train station. When you take your shoe off, finally, your ankle does not look good. When you finally get the MRI’s and the doctor explains just how much you tore, it will…
