Making Species Identification Accessible to the Masses

I was out in a prairie this morning (on crutches) and managed to get a little photography done.  Very frequently, I think about how fortunate I am that most of my photography happens out of sight of the general public, and today was a particularly good example of that.  I was army crawling along the ground with my splinted right foot in a plastic bag to protect it from the dewy grass, dragging a camera and tripod along with me.  Then I had to crawl back to my crutches, sling my camera bag over my shoulder and crutch along to another spot.  I managed to get a few decent photos, but missed a lot of potential insect shots because it takes me too dang long to get my body into place, and even the most patient insects can’t afford to wait for that slow and painful process.

Later, while going through my photos back at home, I grabbed a plant key (“Flora of Nebraska”) to make sure I was correctly identifying the New Jersey Tea I’d photographed.  There are two species in Nebraska, and I can never remember which is which.  As I was reading through the descriptions of the two species, I laughed out loud at the technical terms I had to wade through.  I understand the value of using precise language to describe plant (or animal) characteristics in a dichotomous key (a kind of flow chart used to step through characteristics of various species until you finally figure out which species you’re looking at).  At the same time, the avalanche of technical language that falls upon readers of identification keys also makes identification of species much less accessible to the average enthusiast.

I think I’ve correctly identified the New Jersey tea plant I photographed this morning as Ceanothus herbaceus, but it took a lot of glossary-searching to make my way through the descriptions.

We conservationists are always complaining about how people don’t learn basic natural history anymore.  One of the most important components of that learning process, of course, is identification of species.  Imagine someone who finds a plant they think might be New Jersey Tea, is excited to identify it so they can learn more about it, opens up the Flora of Nebraska, and reads this actual sentence:

“Capsules dehiscing loculicidally into 3 1-seeded lobes, the saucer-like hypanthium fused to it but persisting after the fruits have fallen; seeds reddish brown, plano-convex, the flat side with a low keel.”

Gee, I wonder why people are so bad at identifying species?

There has to be a better way.  Again, I completely understand the need for technical guides for species identification that use agreed-upon and well-defined terms.  But can we either add accompanying language in common English or create translated versions of those identification books that can be read by non-experts?  If we can translate books of literature, can we also translate books of technical jargon?

I played around with this idea briefly, and it’s a lot harder than you might think.  First, there’s the challenge of deciphering the individual words.  The glossary at the back of The Flora of Nebraska is over 30 pages long, and reading it brings back memories of trying to read dictionary definitions back in elementary school – most definitions require looking up more terms just to understand the initial definition.

Second, the advantage of technical terms is that they have very specific meaning, and that helps reduce the number of words needed to describe a concept.  The Flora of Nebraska describes New Jersey tea flowers as being umbellate, which basically means the blossoms are located on the end of stems arranged like an upside-down umbrella.  Umbellate is a pretty efficient way to say that.  Instead of being able to describe how a species differs from others with a paragraph or two of text, accessible language might require a page or more to say the same thing.  That causes its own problems.

For example, in the above description of New Jersey tea, the seed capsules are described in seven words (“Capsules dehiscing loculicidally into 3 1-seeded lobes”).  Very efficient.  While the words are awfully cryptic to most of us, at least there aren’t very many of them!  Translating those seven words requires a lot more words.  Saying the seed capsules split into three parts, with a seed in each, isn’t too bad.  The bigger challenge is the word “loculicidally” which describes where the split occurs on the capsule, a characteristic that helps separate New Jersey tea from other plants.  The glossary describes loculicidal dehiscence as “dehiscence on the locules rather than along the septations”.  Now we have to define both locules and septations.  See what I mean?  Good grief, this is difficult.

Can you see how these seed capsules are dehiscing on the locules rather than along the septations?  Yeah, I bet you can.

I don’t have a good solution to this.  One answer, of course, is field guides, and those can be great for animals like birds or large mammals.  But field guides don’t work well for all organisms, especially plants, fungi, and many invertebrate groups because there are way too many species to fit them into a field guide, and distinguishing species from one another often requires magnification and characteristics that aren’t easily depicted in a single photo or drawing of the organism.  Field guides can get us so far, but if we want people to learn how to identify more than just the common prairie plants, it would be great to have more extensive guides.

I still think we could do a better job of making comprehensive species identification guides more accessible, but the task is gargantuan.  It’s hard enough to put out a good resource like Flora of Nebraska, with precise and efficient terminology describing each species.  If we ask authors of that kind of publication to additionally provide accessible translations of each description for lay people, we risk never get anything published at all.  At the same time, I hear there are lots of youngish biologists with advanced degrees who are having a hard time finding gainful employment.  Maybe we can put some of them to work as translators.  Anyone want to fund a big endowment to pay for it?  Yeah, me neither.

Regardless, I really do think this is an important issue that deserves some thought.  Not everyone can cheat the way I do, which is to shamelessly send photos and/or specimens to experts who can identify them for me, saving me hours of trying to look up and decipher words like “loculicidally”.

P.S.  I want to be clear that I am not criticizing The Flora of Nebraska or its authors in any way.  That book is a fantastic and invaluable resource, and I use it frequently.  The issue at hand is much broader than any individual publication.  Robert, Dave, and Steve – you guys are heroes for getting that book done.  Thank you.

Properly Portraying the Power of Prescribed Fire

At a recent Nebraska conference, Shelly Kelly of the Sandhills Task Force made a point worth some serious consideration.  She told a roomful of wildlife biologists that if they want reluctant ranchers to seriously consider using prescribed fire, using photos of big scary flames in presentations and social media posts is probably counterproductive.  Instead, Shelly suggested sharing more photos of fires that are clearly under control, with people calmly working around them.  Even better, she suggested, we should share photos of green grass beneath the skeletons of dead invasive trees, showing the positive results that follow fire.

We got our first prescribed fires of 2018 done last week.  This photo captures some of the 5 minutes or so of intense fire following about an hour of boring backing fire lines on one of those burns.

I appreciate her point.  Most of my favorite prescribed fire photos are the ones I took during the big head (wind-driven) fire at the end of a burn – when the flames are high and there’s lots of color and action.  Visually, those images are certainly more powerful than photos of a small fire backing slowly into the wind during the early stages of a burn.  However, it’s important to remember that “powerful” might not be the attribute to lead with when talking to a skeptical audience that fears the potential negative consequences of fire.

On the other hand, I don’t necessarily think we need to stop showing people powerful images of fire – we should just try to provide appropriate context for those images.  After all, the power of fire is why it’s so valuable as a management tool.  It can take some pretty tall flames and a lot of heat to kill eastern red cedar trees, for example.

Context is important.  Posting an image of huge flames and a towering smoke column on Instagram or Facebook with a short caption like, “Woo Hoo!!  We had a great burn today!!” will probably get lots of likes from experienced fire folks.  However, someone unfamiliar with prescribed fire might look at that same image and assume it was taken by a reckless pyromaniac who was endangering the public and him/herself.  As a result, that person might be much harder to turn into a prescribed fire supporter.

Expounding a little in an image caption can help quite a bit.  Something like, “Here’s an image from the finale of today’s controlled burn.  After two hours of slowly burning out a boundary around our fire unit, we were able to send this hot fire through the prairie to kill lots of invasive trees before it ran into what we’d burned earlier and put itself out.”  Or whatever – you get the idea.

We start each burn with a small test fire in the downwind corner . That gives us a chance to see how the fire and smoke are going to behave before we commit to the whole enchilada. If we don’t like what we see, we can easily shut down and wait for a better day.  Last week, we had dry conditions, but wind speeds were low enough that we could burn safely.

Even better, we should probably share broader series of images showing the entire process of the fire, including the boring backing fire that sets the stage for that big finish.  Photos of a nice straight firebreak, with black on one side and unburned grass on the other, can help drive home how careful, competent, and effective we are.  After posting a few shots of people in yellow suits laying down lines of small flame inside neat boundaries, it’s probably ok to slide in a couple photos of flaming infernos and torching cedar trees.  It might be smart to include at least one more photo after those flashy shots, though, showing that everything turned out well in the end…

In this photo, we’re laying down a band of water along the edge of a mowed strip surrounding our burn unit, and Olivia is lighting the grass just upwind of that wet and mowed line.

With both a wet line and a mowed firebreak to catch it, Alex lit a line of fire that we allowed to back into the wind. Several vehicles with water followed behind to make sure the flames stayed inside the unit.

Eventually the backing fire created a wind band of black that acted as a catcher’s mitt when the big fire ran into it later.

Once the black lines were prepared, we ignited the upwind portion of the unit and allowed fire to roar through the unit until it hit the black and was extinguished.

These lines of fire are safely inside wide bands of black that have already burned.

Olivia watches the last of the smoke dissipate as the fire burns itself out.

I’ll try to follow my own advice about fire communications in the future, and you can remind me when I forget.  It’s absolutely appropriate to celebrate the power (and let’s face it, the beauty too) of fire by taking and sharing photos.  However, we should also celebrate and share the care and strategy that go into making those powerful fires safe and effective.

Be safe out there.
