Photo of the Week – December 15, 2016

From time to time, I like to use this blog to provide important public service information.  Today, I am attempting to fill an important gap in the bank of available prairie ecology images.  I looked and looked online but was unable to find any photos of insects on prairie dog poop.

Now there will be two.  You’re very welcome.

Rocky Mountain bee plant (Cleome serrulata) is very pretty, for a weed.  It’s an annual plant that grows in disturbed areas like road edges and around livestock watering tanks.  In that sense, many people would call it a weed.  However, it’s also a beautiful native wildflower that can grow more than four feet tall and is a favorite among pollinator insects.

Around Nebraska, I see Rocky Mountain bee plant mostly in the western 2/3 of the state on sandy or loess soils.  It can colonize bare soil pretty quickly in young prairie restorations or after dirtwork projects, and also likes places where perennial vegetation is continually stomped down by cattle or otherwise severely weakened.  It doesn’t seem to withstand much competition, however, and usually disappears pretty quickly once other plants start to enter the scene.  In our Platte River Prairies, we see it often in the first year after we plant a restored prairie, but rarely after that.

While it is not in the mustard family, Rocky Mountain bee plant’s long skinny seed pods that dangle beneath the flowers are certainly reminiscent of mustard plants.  (It is in the same order – Brassicales – as mustard plants.)  Interestingly, while the plant has an unpleasant smell and isn’t often eaten by herbivorous animals, there are many traditional uses by humans that include dyes, medicine and food.  It is also an extremely attractive plant to bees and other pollinators, and the seeds are readily eaten by birds.

Bees like this bumblebee (Bombus griseocollis) are particularly attracted to Rocky Mountain bee plant, as the name would suggest.

There are many plant species that colonize areas where other plants have been removed, weakened, or haven’t yet established.  It’s a really important role in nature, but one that is often underappreciated, and even denigrated – thus the label of “weed”.  Many colonizing plants lack pretty flowers, are spiny, or otherwise make themselves easy to dislike.  A few, though, are so attractive that even the staunchest weed haters might hesitate at labeling them as something bad.

Photo of the Week – December 1, 2016

Insect identification is unfair.

I came across this photo yesterday while looking through some images from last summer.  The photo caught my eye and I thought maybe I’d write a short natural history blurb about it and use that as my “Photo of the Week”.  My first task was to figure out what kind of butterfly is in the photo.  No problem.  I’ve got field guides and the internet.  How hard could it be?

A small

A small butterfly uses its long tongue to extract nectar from common milkweed at our family prairie near Stockham, Nebraska.  If you click on the photo you can look at a larger version of the image and get a better look at the tongue.

I’m no butterfly expert, but I spent parts of a few summers learning butterflies back in the late 1990’s and have held on to much of my knowledge from that time.  I can usually identify the more common butterflies by sight and narrow others down enough that I can pretty quickly use a field guide to finish the job.  Skippers can cause me some problems, but they can be difficult even for seasoned butterfly biologists.  (Skippers are like the sparrows of the butterfly fauna – little brown fuzzy jobs that all look about the same.)

My first thought was that the butterfly was a pearl crescent.  That’s a common butterfly species around here and it looks much like the critter in the photo.  I looked it up, but the spots on the underside of the wing don’t quite match up.  The butterfly in the photo has more white patches than those in the field guides and online.

Next, I looked at the Gorgone’s checkerspot, another species we see quite a bit here.  No luck there either.  The patterns on the underside of the wings are really different from the butterfly in my photo.  I looked at the “Butterflies of Nebraska” and “BugGuide” websites and browsed through a number of other choices, including some species that only show up occasionally in the state.  Still no luck.  Frustrated, I left for a meeting, figuring I’d try again later.

By complete coincidence, my meeting today was about pollinator monitoring strategies, and the first two people I ran into were both butterfly experts.  Aha!  Since we had a few minutes before the meeting started, I grabbed my laptop and pulled up the photo in question.  They both stared at it, but neither gave me a quick answer.  I felt both better (it’s not just me!) and worse (come on, man, this isn’t supposed to be this HARD!).

After some hemming and hawing, the conclusion was that it’s probably some kind of crescent (Phyciodes sp.) but they couldn’t do any better than that.  To be fair, neither of them had access to field guides and it was a surprise question.  Still…  One of the biologists pointed out that not only do male and female crescents have different patterns, there can also be significant differences in patterns between different generations within the same summer.  What??

As a result of all this, I’m stuck not being able to tell you much natural history about this pretty little butterfly other than it’s probably some kind of crescent.  Interesting, huh?  About 30 minutes of my poking around in books and online, two butterfly experts looking at my photo with me, and that’s the best we’ve got.  Well, that and one unarguable conclusion:

Insect identification is unfair.

The Mechanics of Conservation

Years ago, we hired an older mechanic (older than me, anyway) to take care of our equipment so I and other staff could focus more on ecology and land management and less on carburetors and oil changes.  Fred (not his real name) always seemed a little grumpy.  That was completely understandable, given his responsibilities.  Not only was our equipment old and worn out, we tended to be pretty rough on it.

Trained as ecologists, not mechanics, we often used equipment for purposes it was never intended for. (“You know that old Massey combine was built for harvesting soybeans on flat fields, right?  Not for harvesting dense prairie cordgrass in wet meadows or rose hips on steep hills??”)  Even worse, we were pretty cavalier about checking oil, greasing zerks, and other basic maintenance.  When equipment inevitably broke down, Fred would come out with his tools, grumbling under his breath about carelessness and laziness, and fix the problem.  The next time we used that particular piece of equipment, we were likely to see a note scrawled on the equipment in paint marker reminding us to “CHECK OIL BEFORE DRIVING!”, “DRIVE IN LOW GEAR!”, or “BLOW OUT THE RADIATOR!”   We always knew Fred was mad when the paint markers made an appearance.

I’ve often thought that land managers are much like mechanics.  Instead of maintaining machines, we are charged with keeping natural areas working properly.  Sometimes, we’re called upon to fix (restore) land that has been degraded by chronic overgrazing, broadcast herbicide use, or even tillage.  Other times, we just perform minor tune ups to keep things humming along.  There isn’t really an end point to land management, no pinnacle of success to be reached.  Instead, success is being able to hand off a piece of land to the next manager and feel good about it.  “Welp, here’s the keys…”

Because he cared about the equipment he was responsible for, Fred always got justifiably frustrated with us when we would fail to take obvious (to him) steps to help prevent a potential breakdown.  He also felt personally offended when he saw machinery – ours or otherwise – that was obviously neglected and rundown.  We land managers experience the same emotions about land.

We understand the importance of plant and animal diversity in prairies, for example, and know that good management can maintain both that diversity and the ecological function it supports.  It is immensely frustrating to see prairies neglected and over-run by trees or other invasive plants.  It can be even harder to watch a prairie get chronically overgrazed, broadcast with herbicide, or (especially) tilled for row crop production.  We have a deep understanding of what’s lost when prairie is degraded or destroyed, and we appreciate how difficult restoration can be.

Just as Fred got cranky with us because we didn’t take care of the equipment he was invested in, it’s easy for us as land managers to feel the same way about people who neglect or abuse land.  However, whenever Fred would gripe at us about what we were doing, we tended to tune him out (“Oh, that’s just Fred – he’s always cranky about something.”)  Only on the rare occasions did he calmly explain why it was important to do something and how it might affect us personally.  That’s when we actually listened.

I think there is an important lesson here for land managers and anyone involved in conservation.  Being grumpy doesn’t build credibility.  People don’t usually respond well when you lash out at them or make them feel dumb or lazy.  If we want to change the way people treat land, we need to figure out the motivation behind what they’re currently doing and start a conversation there.  Often, they have good intentions but lack the information and larger context that we have.  We can help with that.  Demonstrating what good land management looks like and showing how better habitat helps wildlife, pollinators and humans will go a long way toward improving the world around us.

Land managers

It’s vital that land managers share what we learn with other land managers, land owners, and others.  Looking at management results on site can be the most effective way to trade ideas and strategies, but there are other options as well.  Starting conversations is the first step.

A related lesson is that working in isolation doesn’t change the hearts and minds of others.  Most land managers tend to enjoy working alone, or in small groups of like-minded people.  While that may be comfortable, it doesn’t help inspire action on other lands.  Inviting people to well-managed land for field days, volunteer work days or similar events can show others what great habitat looks like and motivate them to imitate good work.  Sharing effective strategies and important lessons through presentations and publications can reach a broad audience.  All land managers are constantly learning, but unless that knowledge is shared, it isn’t advancing conservation.

There is plenty to shake our heads about these days.  The human race does a lot of silly things, and it’s tempting to just around and grumble to ourselves about it – or to snipe at anyone who offends us.  That doesn’t really get us anywhere, though, does it?  Instead of griping, let’s start conversations.  Let’s find out what others care about and explain what conservation looks like to us and why it matters.  Let’s be proactive about sharing both the lessons we learn and the wonder we gain from our lands.

After all, I think we can all agree that empathy and conversation are more effective than paint markers…

Photo of the Week – November 23, 2016

Prairie landscapes are often defined by broad sweeping vistas and big skies.  A wide-angle lens can be great for capturing that kind of huge open landscape.  However, I’ve gotten some of my favorite Nebraska landscape photos when I’ve exchanged my wide angle lens for a telephoto.


Sandhills and windmill in Cherry County, Nebraska.  My zoom lens was set at 122 mm for this shot, just long enough to get both the horizon and windmill in the photo, but still short enough to still show some landscape breadth too.

Using a long lens compresses a landscape and shows off the depth and texture of a landscape in a way that is very different from an image taken with a wide angle lens.  The above photo of the Nebraska Sandhills came after several attempts to capture the immensity of the prairie with a wide-angle lens.  My wide-angle lens showed a lot of the landscape, but it looked relatively flat and unimpressive – especially because there wasn’t anything going on in the sky.  A longer lens brought the distant hills closer and made them more prominent.  It also cut most of the sky from the image, leaving only the interesting parts of the scene.

Sandhills sunrise

In this Nebraska Sandhills photo, a 300mm lens not only compressed the hills, it also made the rising sun look large enough in the image to reflect the way it looked in real life.

Sunrises and sunsets, along with moonrises and sets, can often be disappointing in photographs because the sun/moon looks much smaller in the photograph than it does in real life.  A long lens can help make the orb look more like our eyes see it when we’re there.

Setting moon

What works for the sun also works for the moon.  On this early morning, the moon was going down behind the bluffs at Scottsbluff National Monument in western Nebraska.  (Zoom lens set at 230 mm)

The photo below is one of my all-time favorites from the Niobrara Valley Preserve, and is actually a scan of a slide from back when color slide film (Fuji Velvia!!) was the state of the art in nature photography.  Just as in the windmill/hills photo above, there wasn’t anything interesting happening in the sky, but the light was good (getting close to sunset) and the sideways light provided great texture on the distant hills.  One of the hallmarks of the Niobrara Valley Preserve is that it hosts a convergence of multiple ecosystems, and this photo shows many of them.

Niobrara Valley Preserve

The Niobrara Valley Preserve as seen from a ridgetop north of the river.  The use of a 300mm lens allowed me to include many of the different ecosystem types all in one photo, including tallgrass prairie/oak savanna in the foreground, the Niobrara river and its floodplain, deciduous woodland and ponderosa pine stands, and Sandhills prairie.

If you find yourself standing on a high ridge or hilltop and can’t seem to make the landscape look as impressive on camera as it does in real life, try using a longer lens (or using the zoom on your phone or point-and-shoot camera).  Though it seems counterintuitive, zooming in can sometimes help show off a broad landscape better than zooming out.

Photo of the Week – November 18, 2016

Back in April, I wrote a post about the regrowth after one of our spring prescribed fires.  That’s a fun time of year to burn because the growing season is getting started and the response of green plants pushing through the black ash comes strong and fast.  Typically, fall burns don’t show any green-up until the next spring.  This year, however, the crazy warm weather has changed things a little. In the two burns we’ve done this fall, most of the ground is still black and barren, but here and there, some green is pushing up through the ash as well.

Here are some photos I took this week of a burn we conducted two weeks earlier.  The site was a recently restored prairie (2013 planting) and this was the first burn at the site.  Green plants weren’t the only interesting things I found as I walked around.

Big bluestem skeletons

Big bluestem skeletons stand tall in the ashes.

Cedar tree

Cedar trees are uncommon on our land because of our consistent use of fire.   This one won’t give us any more trouble….

Some grasses and sedges

Despite the lateness of the season, patches of grasses and sedges were showing signs of growth, taking advantage of warm days and some recent rain.


Sedges often stay green well into the winter, but I was still surprised to see these actively growing after a fire.

Goldenrod galls

Among the scorched plants were goldenrod stems with galls.  The insects in these galls left well before the fire, but there other invertebrates overwinter in aboveground plants and are vulnerable to dormant season fires.


The bare sand of pocket gopher mounds stand out against the dark background.  Ant hills, vole runways, and mole tunnels were also spread across the burned area.

Sunflower stalks

Most plants burned completely, but in some places, fire intensity was lower and bigger stems of sunflowers and other plants only partially burned, sometimes falling as if they’d been chopped down.

Back fire

Lines of fallen grass and forb stems show where the fire backed into the wind, rather than being pushed by it.  In a backing fire, only the lower parts of plants are consumed, and the wind blows them over into the already burned prairie where they escape being further burned.


A white skeleton of a long dead rabbit (I think?) was left tarnished but intact by the fire.


Near the edge of the burned area, grasshoppers skipped away from my feet as I walked.

Hubbard Fellowship Blog – Scaling Up the Emotional Impact of Prairies

This post was written by Eric Chien, one of our Hubbard Fellows.  Eric comes from Minnesota and brings great energy to our prairie stewardship work.  He’s also very bright, and an engaging writer, as you’ll see in this and other posts.

I recall vividly the moment I was swept up by prairies; when what had only been a textbook description of geography was sparked into a fidelity to place. The view of sandhill cranes swirling over a starkly beautiful late-spring prairie had an immediate impact on me. It was the first time I felt what I was seeing.

Sandhill cranes.

Sandhill cranes.

I have been recalling this moment lately because I have been thinking a lot about impactful experiences. I was there that blustery Spring morning for work. There was no one there to interpret or inspire. No learning objective or deliberate takeaway. Yet, that experience sits amongst the foundation of where I am now and the path I continue to take.  Impactful, emotionally rich experiences are the touchstone for action and commitment, and in prairies, in relation to other landscapes, they seem a little harder to come by. Prairies just don’t give themselves up easily. Identifying those places, characters, and moments that bridge the gap between knowing and caring could be a powerful tool for the achievement of conservation goals, and enriched human lives.

I have often struggled to facilitate powerful prairie experiences for others. Deep appreciation always seems to end up relying on the context of my own knowledge and memories, and thus unapproachable to my companions. One of the few places where prairies do not play hard to get is the Niobrara Valley Preserve (NVP). It has long been a place that confers experiences capable of tying together people and prairies. Its reference list is long and diverse. Somewhere within the consistent transfer of emotional weight that NVP delivers is an important guide and mold for reaching others.

On a recent evening, I found myself sitting quietly beneath a cedar in Niobrara River valley prairie at dusk. Within minutes of my settling in, a small group of bison had quietly foraged their way down from the hills, and into this football field prairie flanked by oak-cedar woodland and the river. They were unhurried, only the occasional soft grunts accompanied the sound of little bluestem, cured wine red, being clipped off. I felt lucky that from the 12,000 acres of prairie on which they could wander, this small group had happened to choose this minute pasture for the evening. They were soon joined by a large flock of Merriam’s Turkeys. Their white tipped tail fans flashed as they scratched at the ground, flipped bison paddies, and bantered with purrs and clucks. A young whitetail buck also joined the evening stage. You can see him inquisitively wander towards me in the video below.

Before it became too dark I walked up and out of the river valley, cresting the hills, and was confronted with the stretching upland prairie of the Sandhills. A spooked pair of young bison bulls thundered off the river ridge and into the hills out of sight. I walked the sandy, two track back to the bunkhouses in the dark. These are not uncommon moments at NVP. The source of gravitas in these experiences may seem obvious, filled with charismatic wildlife, but I think it is more than that. The widely shared appreciation of NVP says a lot about where we are coming from in prairie conservation and where we want to be.

Conservationists will accurately tell you that a 54,000 acre preserve is still far from a whole system. The Nature Conservancy does not control the entire Niobrara River Watershed, our bison herds need to be fenced in, and invasive plants still find their way onto the preserve. However, it is one of an elite few locales that feels whole. I believe it is this sense of wholeness that beckons people to deeply connect with it in a way that is difficult in most other prairie landscapes. When I am showing people prairies, I often find myself asking them to imagine. Imagine if this highly diverse, visually stunning, 80 acres of prairie stretched to the horizon. Imagine if a herd of bison lay hidden behind that low swale. Imagine if you did not know what else might be out there. At NVP, one does not have to imagine, and in that lies its power to move us.

Large, intact, productive grasslands, like the Niobrara Valley Preserve let us transcend the conservation context in which much of our work takes place. We can escape the long road of restoration in the human dominated landscape, characterized by fragmented, degrading, homogenous, biologically depauperate prairies. We can see the prairies and landscapes we are driving at. As prairie professionals and conservationists, we should and do spend most of our time on this long road, but as we seek to bring others into the fold we should strive to impart them with a vision. Head off the question about why prairies are important; the one that often seems to accompany a trip to some isolated remnant in a sea of cropland. Take them to somewhere where the importance of prairies is unspoken and self-evident. Seek to move our potential prairie allies from “is that all?” to “what else is out there?”. I know that is harder for us here in the prairie than for those sharing other ecosystems. It is especially hard in the eastern tallgrass prairie where we have been left with nearly no truly large prairies. That said, the hard work of many (Nachusa Grasslands IL, Midewin National Tallgrass Prairie IL, Glacial Ridge National Wildlife Refuge MN, Kankakee Sands IL/IN) has made it more of a possibility than ever.

For some, the beauty found in small prairie patches is sufficiently captivating. For others, however, a sweeping landscape of prairie

For some, the beauty found in small prairie patches is sufficiently captivating. For others, it is the sweeping sea of grass that triggers a love of prairie.

There will always be those who will come to prairies more subtly; those who are innately curious about the details of plant communities, who can discern and explore the intricacies of prairie ecology that happen at the smallest of scales. I will happily continue to walk with anyone who shows enthusiasm for finding fritillary caterpillars on rare prairie violets. Prairie conservation and restoration by necessity has been built on the backs and through the sweat of those who can delight in our valuable remnants, and push forward from there. Let’s also begin to work from the other direction. Recognize that there are those who will only come to prairies through experiences of grand space and wildlife. Bring them to the end, let them see what else prairies can be. After that we can walk them back to where we are, and begin the work of the return journey to wholeness with the expanded support of more “prairie people.”

Photo of the Week – November 11, 2016

On Wednesday of this week, we took advantage of the eerily warm November temperatures to conduct our second prescribed fire of the fall.  This one will help concentrate some spring grazing in an area where we want to suppress grass dominance and rehabilitate forb diversity.  The fire was also a great opportunity for further training of some young conservation staff.  In addition to Eric and Katharine, our two Hubbard Fellows, we also had three young interns/technicians from a couple of our conservation partners, the Crane Trust and Audubon’s Rowe Sanctuary.

Anyone who has seen prairie fires up close gains an appreciation of their speed, heat, and power.  Harnessing a force like that to achieve prairie management objectives takes careful planning, solid training and good equipment.  The fire this week went as smoothly as could be hoped for, but  – as with every burn I lead – my stomach was still knotted up until the last of the big flames had been extinguished.  After we were done, I took a leisurely and therapeutic walk around the perimeter of the burned area, both to confirm that everything was secure and to envision the positive impact the burn will make as next year’s growing season begins.
