I am an ecologist because baselines are shifting

I grew up in Calgary, which is in southern Alberta. The city itself sits right at the intersection of the Great Plains and the eastern slope of the Rocky Mountain. The Elbow River flows into town from the south and meets the Bow River where downtown now sits. The Bow itself flows from Banff in the west, through Calgary, and to the south and east until it joins up with the Oldman River, which empties into the South Saskatchewan River, which joins with the North Saskatchewan to form the Saskatchewan River. The water that started up in the moutains at Bow Glacier eventually ends up in Lake Winnipeg, and from there in the Arctic Ocean by way of Hudson Bay.

My family home was on the edge of downtown Calgary. In that respect you won’t find too many people who had as urban an upbringing as I did. But Calgary is a special place, particularly in its river valleys, because of the easy access that good civic planning (which has thankfully continued to this day) provided a rather “free range” kid like me to urban-wilderness spaces. I spent a great deal of time on the hill outside my house. At a young age — surprisingly perhaps in the contemporary era of nature deficit disorder, but not at all unreasonable in the 1980s — my parents were quite fine with me wandering down winding paths on the hill, fly rod in hand, to the Bow to see if I could rise a trout or two. Family holidays were never at a preprogrammed resort, but were spent in the mountains of Alberta or British Columbia; or on the prairies east of town and out to visit family in Medicine Hat; or further east exploring Saskatchewan.

Because of all the time and freedom that I had to spend on my own fishing the Bow, or calling magpies — always and forever my favorite bird — with homemade predator calls in front of my house, or sitting in the back seat for hours on end driving across Canada’s three western provinces on family holidays (and no iPads in the car, of course), I had more than ample time to contemplate the natural world around me.

I saw the Canadian Rockies and other ranges, mainly untouched except for ribbons of roads in the national parks, but substantially logged outside of those protected areas.

I saw the Bow and the Elbow, and felt the water on my legs rise and fall with upstream dam releases.

I caught beautiful brown trout that I knew had been introduced in the past in a mistaken stocking event.

I watched grass fires on the hill in front of our house, likely started by a discarded cigarette on the path at the bottom, burn through the prairie vegetation like fire is supposed to do, although we rarely let it do so anymore.

On long drives beneath the prairie sky dome during family vacations I looked across vast fields of canola, glowing yellow under the never ending blue, and wondered what it would have been like to see Saskatchewan before fences, before the bison were gone.

By my early teens I realized that the things that I was experiencing were not the way that they had always been. Despite how wonderful the world around me was, it had been diminished — sometimes in small ways, sometimes very dramatically. This is not to say, of course, that humans weren’t sometimes taking care of it and using it in good ways to feed, clothe, and shelter themselves and other humans. Rather, simply that something had been lost and that sometimes in our valid efforts to satisfy our needs we neglected the animals, plants, soil, and water in the rush to extract. Even that early in life I realized that neither I nor my children nor their children would ever experience an unfenced prairie out to the horizons, or an un-dammed Bow River. Although I didn’t call it that, I understood that there was a baseline that was now lost. And I understood that even though I wanted to imagine what had been there before I saw it, I never could truly know. I could surmise, extrapolate backward in time, and imagine. But I could never actually live it.

Whether I knew it or not, those incipient thoughts were similar to what Daniel Pauly called the Shifting Baseline Syndrome. Speaking about fisheries management, Pauly wrote, in a short, influential article:

Essentially, this syndrome has arisen because each generation of fisheries scientists accepts as a baseline the stock size and species composition that occurred at the beginning of their careers, and uses this to evaluate changes. When the next generation starts its career, the stocks have further declined, but it is the stocks at that time that serve as a new baseline. The result obviously is a gradual shift of the baseline, a gradual accommodation of the creeping disappearance of resource species, and inappropriate reference points for evaluating economic losses resulting from overfishing, or for identifying targets for rehabilitation measures.

In other words, relatively short-lived humans are prone to take the current situation as the “way it always has been” and to react to that rather than to what can be often lost to the memory hole of the past. This tendency needs some form of inoculation, because no one is inherently immune. That inoculation is having people here and now who are committed to measuring the baseline and ensuring that our records travel in time to the future. It is also up to those of us who are here now to do our own time traveling to the past by making sure that we are reading those sometimes very hard won records of our predecesors.

I can honestly say that I don’t fully know why I chose a career as an entomologist and ecologist. Reasons for any large life directions are usually found in multiples, and like any ecologist I know that there are very few outcomes that result from only one influence. However, I suspect what I am passionate about today had a great deal to do with my freedom to explore as a child and my primordial understanding of the lost baseline. I certainly do know that is what drives me today — specifically the hope to understand and record the small part of the world in my current backyard so that someone in the future might look back to get a glimpse of what is now to me, but what will be “what was” to them. And so that a future society can make wise choices in their management of the environment and of the resources that they need to extract.

We need to catch the current baseline. We need to record it. And we need to make sure that the records move into the future after our personal constituent parts succumb to the second law of thermodynamics. No one of us can do all of that, nor could even an army of ecologists in a plethora of sub-disciplines hope to record the full baseline. The blessing of the Anthropocene is that we have access to just about any spot on the planet and we have amazing new tools that we can use to observe and record deeper than ever before. The anathema of the Anthropocene is that humanity’s joint effects are changing those spots faster than we can hope to measure them.

But, despite the challenges, we need to make those measurements because without them a future that we can’t imagine won’t be able to imagine our present, their past.

Update: that transit facility

A few weeks ago I posted a letter that I sent to City of Prince George Mayor Lyn Hall and Council. My letter was just one small part of a massive community organizing effort regarding the proposed building of a transit facility in an urban green space.

Yes our city needs a new transit maintenance facility. No, we should not be building it in green space.

Today the Mayor and three councillors put out this report to council asking that at their next meeting (this upcoming Monday) council vote rescind the motions for approval of the facility in that location and instead direct city staff to work with BC Transit to find a better site for the facility.

Yes, this still needs to be voted on at council, but I’m optimistic that it will pass as it already has substantial support as evidenced by the Mayor’s report.

I hope that this groundswell of concern translates into a longer-term vision for preserving, expanding, and improving our urban green spaces here in Prince George – whether in our own backyard or in that of someone else.

Thanks to the organizers of this effort; to Mayor Hall and Councillors Frizzell, Scott, and Skakun for taking part in the disucssion and for being responsive; and to the many citizens who voiced their opinions in a variety of venues.

Let’s work to see this vision and passion for the value of our urban green spaces continue to spread like the forest canopy that we have now preserved in hope and anticipation of the benefit for future generations.


As I posted in my letter to council, here are some related resources that may be of interest:

Thoughts on a proposed urban development

Dear Mayor and Council members:

I am writing to express my concerns about the proposed transit facility at 18th and Foothills. I have previously written letters about the Ron Brent development (which unfortunately went ahead) and the North College Park proposal. As with those letters, my general theme here is that green spaces and parks – particularly those that are substantially used by the public and/or that provide other important ecosystem services – should not be open to residential or industrial development. Once we lose one of those spaces, we have lost it and the valuable services that it provides for decades – essentially forever.

As noted in a recent Prince George Citizen editorial, the City of Prince George has an unfortunate history of making poor decisions in situating both major and more minor developments. In the case of the proposed transit facility this is a much-needed facility in one of the worst possible locations. Please, let’s not continue the legacy of developing in the wrong locations simply because space exists.

I recently attended the annual Canadian Society for Ecology and Evolution meetings in Victoria. One of the symposia that I attended was on urban ecology. The speakers were engaging, and the projects that they described were inspiring. The thing that stuck out to me the most, however, was that my own city is at least a decade behind in terms of our thinking on this subject. While other cities are preserving and rehabilitating parks and green spaces, we are looking for ways to reduce our green spaces and with it the biodiversity, ecosystem services, corridor connectivity, and recreation and health opportunities that they afford.

Ecosystem services have been shown to include (each word links a different resource):

  • a healthier (mentally and physically) and more active population
  • a reduction in human-wildlife encounters
  • more effective water runoff management
  • less toxic runoff to local waterways
  • cleaner air
  • reduction in soil erosion
  • reductions in sound pollution
  • more shaded areas and thus reduction in sun-related injuries and disease
  • carbon storage and offsetting
  • aquatic ecosystem health
  • higher property values

At the symposium the point was made by Angela Danyluk (Sustainability Specialist at the City of Vancouver) that “vegetation is the foundation of biodiversity” and thus of ecosystem services. Perhaps it is because we have such a richness of vegetated spaces within and beyond our city limits that we tend to see them as expendable; but we should embrace and enhance our richness as a long term investment, not exploit it for short term gains.

One of the points in that symposium was that municipal asset calculations often fail to take ecosystem services into account. A question that needs to be asked any time we are thinking of removing parks and green spaces from city inventory is “what value does this area provide, and what extra costs will be incurred if we lose this area?” In other words, quoting from one symposium participant (Michelle Molnar, an environmental economist with the David Suzuki Foundation), “…asset management should consider not just built areas, but also natural assets.

She presented a slide outlining a small portion of these considerations, which I have summarized as follows.

Green space vs. Built:

  • lower maintenance cost vs. higher maintenance costs
  • carbon-neutral or carbon sink vs. carbon intensive
  • can last into perpetuity vs. limited lifespan
  • climate change resilience vs. climate change vulnerable

Prince George seems to be growing and doubtless will grow further in the coming years. Do we want a city that is a hodgepodge of residential and industrial areas with declining green spaces that are only considered useful for their development opportunities? Or would we rather see healthy residential communities bounded by forests and parks that provide a vibrant and prosperous environment for our citizens?

I know which one I’d prefer, and judging from the success of the petitioning on this topic I suspect that I am part of a much larger majority.

As a daily transit user, I appreciate the attention being given to that vital public system. But it should not happen at the expense of valuable green space when there are many other options to be had in existing industrial areas. We need to move off of our current trajectory and to a more sustainable policy regarding our green spaces and parks. This means prioritizing and incentivizing infill and brownfield development instead of removing park and green space inventory.

(In fact, we should also incentivize rehabilitation of brownfield areas, but that is a topic that goes beyond the immediate intent of this letter.)

The following resources have been useful to me in my thinking on this issue, and may also be useful to you and to City staff:

Thank you for reading this, and I appreciate the work that you do for our fine city.

 

Sincerely,

Dezene Huber


This letter was sent to the Mayor and Council by way of email on 17 May 2017.

Should I pursue this major?

A few days ago one of the academic advisors here at my institution sent me a letter in which a student asked about the utility of a biology B.Sc. I mulled it over in my head for a few days and then responded with (edited a bit to preserve anonymity and for better clarity) the letter below.

In this day of increasing media hyperbole – or dare I call them “attacks” – regarding the value of a postsecondary education, I can understand this student’s worry. For instance, here’s a very recent piece from a big regional/national network that begins with the description:

According to a new study from Statistics Canada, there are some areas of study that you should avoid if you want to get good value out of your education.

This, unfortunately, is what we hear more and more these days. Unlike the pablum normally served to us from the media, I would never argue that someone should not pursue their passion. If their passion is in carpentry, then trade school is the way to go. If they happen to like building cutting-edge technology in their garage, then they should go for it; it turns out that can work out pretty well. And if they really like biology or history or literature or physics, a good place to learn more about those things happens to be a university. When it comes down to it, it’s all about passion. If something is not your passion, then you should not cave in to pressure to pursue it. If it is your passion, then find the best place to explore it further whether it’s technical school, university, or your garage.

One more quick aside: I am bumping into more and more of these queries lately. I suspect it has something to do with a much more difficult economy than has been the case even a few years ago. As something resembling an archetypal GenX-er, I suppose that I have had some experience in this area, as I too graduated into a recession. I’d bet that many of you have thoughts in that regard as well.

Rather than go on any further here, I’d like to present my edited and redacted version of the letter below. Your comments are welcome, of course.

Dear __________,

One of our academic advisors referred your question about whether or not you should pursue the biology B.Sc. major at UNBC to me. Thank you for asking, and I hope that I can be of some help.

Your question is not one that is completely easy to answer. If you are looking for a specific job – and if you know what that job is – then you should find a university degree or technical school certificate program that will lead you directly there. If you are not certain of where you see yourself in five or ten years (and who among us really has that kind of certainty anyhow?) then please keep on reading.

All degrees at universities – biology, chemistry, history, english, etc. – amount to what you make of them. Some university degrees – education, engineering, social work, nursing, etc. – will lead you almost directly to what might be regarded as one general job type. If you take a nursing degree, you end up being qualified to become a nurse. If you take an education degree, you end up being qualified to become a teacher. But, as you note in your question, if you take a biology or a history degree, your qualifications are not seemingly as clear.

So, it depends on what you want. Some degrees don’t lead to a specific career, but also give you lots of flexibility in life. Some degrees lead to – generally – a specific career, but you are mainly locked into that when you are done. No one is ever completely locked in, of course. But certain degrees prime you for quite specific careers.

In other words, the outcome of some degrees is riskier than for others. Perhaps it is appropriate to say that some degrees are more entrepreneurial than others in the sense of entrepreneurial risk.

Biology, of course, is in the no-necessarily-specified-outcome category for the most part. Yes, there are jobs for biologists after their degree. These range from environmental consulting to lab research to academic teaching and research (if you continue on with graduate school) to medicine (if you continue on in medical school) to grade-school teaching (if you complete a education certificate or graduate degree after your biology degree). But none of these is in any way “certain.” Each of them depends on how well you do in your biology degree and how much you embrace and enjoy the subject matter. Each of them also depends on the sort of job opportunities out there at the time that you graduate, and that is not something that anyone can predict (although some will try to convince you that they can).

In my own personal experience, my undergraduate degree was in zoology (animal biology) because I really loved biology and animals in general. I became fascinated with invertebrates and found insects to be particularly cool. I took the opportunities that were presented to me at my undergraduate institution to do lab research, even though it was not on animals. I really and truly enjoyed pretty much every course that I took because they all were showing me new things about the world. I also walked into courses that I thought that I might dislike with an attitude of trying to focus on finding aspects that were interesting to me. Since most of the information in the courses that I took was new, it was not hard to find really cool things about each and every course. For me, it was all about my attitude. Then, as now, I tried to always maintain an attitude of wonder. As a result – because I was engaged in the wonder of it all – my marks when I completed my B.Sc. were very high and I had all sorts of potential options to explore. So the attitude of wonderment served me well back then, and I think that it continues to serve me well today as it opens new doors in research, teaching, and general life.

Because I had developed such a life-long love for biology, and then found out that I also enjoyed the thrill of original research, I decided to go to graduate school. Even during my Ph.D. studies I was not 100% sure what I would “become.” I suspected at the time that perhaps I’d work toward becoming a professor, but I was fully aware that that is not the easiest profession to get into. So I knew that my work in graduate school might not take me to that end point – it did, and I am lucky and thankful that it did, but there were never any guarantees. However I knew that my efforts would prepare me for an interesting career one way or the other, and in the meantime I really, really enjoyed what I was doing.

It’s tempting to look at career opportunities in broad categories – nurse, firefighter, architect, physician, bank manager, accountant. These all exist, of course. But the reality is that most careers – even those on that list – don’t fit as neatly into those categories as guidance counsellors and others will tell you. Many people make very interesting careers for themselves in areas that you likely are not even considering.

I guess what I’m saying is this: when you head into your post-secondary education, take the time to explore the thing or things that interest you. Cultivate an attitude of wonderment. Talk to your professors. Talk to people you know who have careers that interest you and who seem to generally find interest in their daily work. Be willing to be flexible now, and throughout life. Work very hard. Be sure to find ways to enjoy each and every class that you take. And realize that there is no way that you can predict right now where the economy will be in four or five years and where your interests may lead you by then.

All the best in your decision, and feel free to email me with any other questions you may have.

Sincerely,
Dezene Huber

So there you have it. I’d be interested to hear your ideas on improving this letter.

What are your experiences?

What is the value of a non-professional university degree?

Email paralysis?

Science can not operate in a vacuum for very long, and substantial scientific progress is only possible when communication between scientists is efficient and effective. This has always been the case – scientists have always communicated in person at conferences and across distances through letters. Recently, of course, the rate of information exchange has increased exponentially compared to our Victorian-era forebears. Years from now when our chapter of scientific history is written, I am positive that historians will attribute the current rate of scientific advance to exceptional communication technologies.

Email, of course, will play no small part in that explanation. Email has changed a great deal since the days of ELM and PINE when fewer people were using it and getting a message in our inbox was sometimes even a novelty. Today inboxes overflow and explode with messages ranging from annoying spam, to trivial updates and newsletters, to urgent messages that need rapid attention. Email is a great technology, but like any technology it’s a double-edged sword. You need to control it, or it will control you.

Over the years I have fought to avoid being controlled by email and I think that I have generally won that battle. I am by no means successful all the time, and what follows is no email panacea. But I thought that I’d share a few of my methods that ensure that lines of communication flow well through my office while keeping me from pulling my hair out and declaring email bankruptcy.

Consolidate – Remember when you had one email address and that was enough? These days many of us have several email addresses ranging from professional to personal to addresses associated with some of our professional or other tasks (e.g. if you’re a journal editor, you may have a journal-specific email address). I have found that by sending all of my email to one location – I use Gmail for this – I reduce time flipping between accounts and I catch important emails sent to my secondary accounts more rapidly.

Control the pace of the game – Email is like tennis or – for Canadians – like hockey. You need to take control of the game and keep it moving at a pace that suits you. If you find that you are being overwhelmed with a torrent of emails, you need to slow the game down. Three tricks that I use (and should use more often) when I start to feel buried are: (1) only looking at my email at set times in the day; (2) using a tool like Inbox Pause that keep you from seeing email until you want to see it; and (3) not necessarily replying immediately to a message if I think that by doing so it will just result in a volley of back-and-forths.

Don’t use your inbox as a to-do list – This is always a major temptation. But in the end it just makes for a huge list of messages and tasks lost in the shuffle. Instead, have an actual to-do list in a notebook on your desk (and then archive the email), or use a system like Baydin’s Boomerang that sends messages away and then returns them when you need to act on them.

Filter – If you get update emails from your organization, or newsletters from various entities, they can quickly clog of your inbox. They are generally not the sort of thing that you need to read immediately. So use your email program to apply a filter to them and get them out of your inbox, and then take a look at that folder every now and then as you see fit.

Destroy spam – Most universities and other organizations catch some spam on the way in. However, their nets are not always stringent enough for me. Gmail is great for ditching spam, catching all sorts of excess stuff. If you find you are getting too much spam in your inbox, talk to the IT folks at your organization and/or look for efficient spam filters that can be added on to your current system.

Unsubscribe – Speaking of filtering and spam, are all of those newsletters and other subscriptions coming into your inbox really necessary? How many of them to you actually read? How many of them did you really consent to in the first place? I have personally gone on major unsubscribe binges in the past, but ultimately things just begin to pile up again. Recently I have found a service called Unroll.Me that will capture mass emails and give you the options of keeping them coming to your inbox, unsubscribing, or putting them into a daily digest. This tool has, over the past few months, helped me to unsubscribe or “roll up” over 450 newsletters (etc.). Who knew that I had that much coming into my inbox? And I suspect that I’m pretty typical.

As scientists and educators we need to communicate with each other, with our students, and with many people and organizations. But the irony is that our tools can lead to a communicative paralysis that brings everything to a grinding halt. As I alluded to above, my suggestions are  no means a road map to utopia. But doing this has helped me to reduce my general email anxiety and has let me get tasks done when they need to be done. My hope is that some of these ideas might help you to continue to develop your own system and to allow for efficient and effective communication.
