“Technology can help us save the planet. But more than anything, we must learn to value nature.”

The above quote was a headline from a 2018 article published by the World Economic Forum. Its first sentence is not aging well. The second sentence remains true.

Growth in AI and other elements of the digital age is exploding, and so is the infrastructure to support it. Data centers are an overt manifestation of the industry, and an increasingly unpopular one.

Data centers, especially so-called hyperscale centers, are technological monsters. Hyperscale centers typically exceed 10,000 square feet and contain over 5,000 servers. Energy and water consumption can be extreme. Even a midsized center can use 300,000 gallons of water daily. That’s the equivalent of about 1,000 households.

Energy use can soar into the stratosphere. Giant hyperscale centers might require up to 250 megawatts daily. That’s roughly the equivalent of the residential energy use of Cincinnati.

Perhaps 5,000 data centers are now in operation in the U.S., and about 200 are online in Ohio.

Most Ohioans probably only became aware of data centers in the last year or two, and many citizens may still be in the dark about these massive computing operations. This appears to be by design. Tech giants such as Google, Meta, Microsoft and others have operated under a cloak of secrecy regarding their development.

As people have increasingly become aware of data centers and their prodigious energy and water use (and other negative issues), rebellions are fomenting. A local data center uprising involves a proposal to place a hyperscale center on the south side of Urbana, 1.5 miles north of the legendary Cedar Bog, which is perhaps Ohio’s most iconic natural area.

By the time most people learned about the proposed center, the land had already been purchased, and construction plans were well underway. The billion-dollar hyperscale center, as planned, encompasses about 460,000 square feet.

As word spread through the Urbana community and surrounding areas, residents revolted. Scores of people made their grievances known to Urbana City Council. To their credit, council scheduled a March 3 meeting at which citizens could air their concerns.

To accommodate the anticipated turnout, arrangements were made to use the Champaign County Community Center and its 200-seat auditorium. I attended, in part to offer expert testimony about Cedar Bog and its ecology.

The capacious meeting room was inadequate. An estimated 300-400 people came, the room was packed and the overflow extended into adjacent rooms and corridors.

Over 30 people, ages 13 to 91, delivered five-minute statements, and no one was for the data center. The majority also mentioned Cedar Bog, what it meant to them and its importance to Urbana.

A potentially major issue for the bog involves disruption to its hydrology. Cedar Bog is fed by the underlying aquifer, which provides a stable source of cool water. Cedar Bog depends upon clean groundwater to fuel its peaty wetlands. The hyperscale center would perch atop this aquifer, and upstream from the bog.

Over 520 species of native plants occur within the bog, which is over 25% of ALL the plant species in Ohio. Further, the site harbors three endangered plant species, nine threatened species and 14 potentially threatened or watch-list species.

Some are the rarest of the rare, such as prairie valerian, which was originally discovered in Cedar Bog in 1838. There is only one other small population in Ohio.

The most famous plant in the bog is undoubtedly the showy lady’s slipper, North America’s largest orchid. Likely tens of thousands of visitors have visited the bog in June to clap eyes on the giant pink and white flowers of this threatened plant.

Especially notable to botanists are the carnivorous bladderworts. These plants trap tiny invertebrates in sac-like traps attached to their roots. One species is the endangered horned bladderwort. The other species is, well, we don’t know for sure. It may turn out to be a highly localized “new” species not yet described to science.

Cedar Bog also harbors scores of breeding birds, endangered massasauga rattlesnakes and elfin skimmer dragonflies, spotted turtles, five-lined skinks, Milbert’s tortoiseshell butterflies and much more.

Protection of the underlying aquifer is essential to protect Cedar Bog’s fragile habitats. While the developer’s representatives, from CyrusOne and Thor Equities, claim that this data center would use “closed-loop” cooling, thus greatly reducing water usage, their claims were met with great distrust by those at the meeting.

The reps also expressed willingness to meet with all who wished to discuss concerns. Unfortunately, they left the meeting before all of those with concerns went to the lectern to express their concerns.

In an unexpected bit of good news from the meeting, Urbana City Council proposed a one-year moratorium on building the hyperscale center. Seven of the eight council members were present, and the moratorium proposal passed by a vote of 6 to1. The lone dissenter was Audra Bean, wife of Urbana Mayor Bill Bean. He is a major advocate for the data center.

I cannot think of a worse location for an energy-sucking hyperscale data center than the proposed Urbana site. Not only because of Cedar Bog, but also due to the close proximity of a retirement village, an elementary school and many businesses and residences.

Hopefully elected officials will stand with the Urbana residents who elected them and quash plans for this hyperscale data center.

Ohio's iconic Cedar Bog threatened by proposed data center

 

A fen meadow at Cedar Bog, near Urbana, Ohio, in Champaign County. The meadows at the "bog" (it is actually a fen) are full of rare species, including many highly sensitive plants that are extremely particular about hydrology (water regime). Here's a link to a Columbus Dispatch newspaper article that I wrote about Cedar Bog in 2024.

This proposed data center is a short distance upstream (about 1.5 miles) from one of Ohio’s most iconic and sensitive natural areas, the legendary Cedar Bog. If you aren't up on data centers, they are massive computer processing plants that house servers, storage systems, and networking equipment that serve various aspects of the digital economy such as storing, processing, and distributing data related cloud computing, AI, and various online services. To learn more about these centers, and the harm that they cause environmentally, see THIS ARTICLE in Smithsonian Magazine.

The data center would tap water - LOTS of water - directly from the aquifer that feeds Cedar Bog. And the ecology of Cedar Bog is directly dependent upon the health of its aquifer - it is fed by ground water. It’s the worst possible location imaginable to site one of these monstrosities and we should all protest it. Please sign and share this change.org petition protesting the location of this data center, RIGHT HERE.

To inject some science in defense of Cedar Bog, it harbors one of the highest concentrations of rare, highly specialized plants of any site in Ohio. When Barb Andreas, John Mack and I authored the Floristic Quality Assessment Index of Ohio, we used that methodology to score numerous best of the best examples of various plant communities. Cedar Bog scored 45.4 - the highest score of any habitat that we are aware of in the state. Cedar Bog is singled out on page 16. To see a copy of the FQAI, with information about the methodology, GO HERE.

It's a shame we have to spend time and effort defending things that should not have to be defended, but this is just such a case. Please sign the petition, RIGHT HERE.

Bobcat Talk: Next Saturday at Cedar Bog

 

A Bobcat (Felis rufus) pointedly ignores the photographer. I made this image last October, in the Savannah National Wildlife Refuge in Georgia. After a bit, the cat stalked off in the insouciant manner that only a cat can muster.

Shauna Weyrauch, who teaches at Ohio State University's Newark Campus and does research involving Bobcat den sites and is an authority on Ohio's only remaining wild cat (Lynx and Mountain Lion once occurred), will speak on these fascinating felines next Saturday, February 8 at 10 am in the visitor's center at Cedar Bog. Admission is free and all are welcome.

Shauna, along with wildlife photographer Dutch Gordon, recently published a book entitled The Boy and the Bobcat. It's geared towards kids, and I doubt the kid exists who wouldn't be interested in Bobcats. Shauna will have books on hand ($20), and her talk will be of interest to the younger set. Please feel free to bring any kids you have or know.

After the talk, Shauna, myself, and Cedar Bog volunteers will lead a foray around the boardwalk. Cedar Bog is one of Ohio's most remarkable natural resources and is chockful of rare species. Bobcats have been documented there, and though our odds of connecting with one are slim to none, we will see oodles of other interesting stuff. Skunk-cabbage (Symplocarpos foetidus) abounds, and I won't be surprised if some plants are already in flower. Located just south of Urbana, Cedar Bog is easily accessible from Columbus and anywhere else in central Ohio.

Hope to see you there!

NATURE

One of Ohio’s greatest biological hotspots lies less than an hour’s drive west of Columbus.

Cedar Bog is a fascinating place; a glacial relict populated with flora that one would normally have to venture far to the north of Ohio to see.

At the time of European settlement, the Mad River Valley west and south of Urbana harbored a massive 7,000-acre “swamp”. The word swamp is a catch-all term for a variety of wetlands, and the Mad River swamp deserves more discriminating nomenclature.

In 1974, geologist Jane Forsyth did just that, coining what by then had become known as Cedar Bog as a boreal fen.

Boreal refers to northerly regions and is an apropos descriptor for Cedar Bog. The Pleistocene epoch brought the last global ice age, commencing about 2.5 million years ago. As the sheets of ice slowly expanded south, they bulldozed the landscape, creating valleys and depressions suitable for northern plant species.

As the climate then was much colder, boreal plants, such as spruce, fir, tamarack and many others, flourished in what would much later become known as Ohio.

A warming climate eventually spurred the retreat of the glaciers and they had receded to the north of Ohio by about 12,000 years ago. Boreal flora was slowly replaced with more southerly plants, except around the margins of cold glacial lakes and specialized peatlands known as bogs and fens.

Cedar Bog was one of the largest and is exceptional in that it hosts plants of boreal regions and westerly wet prairies. It should be noted that Cedar “Bog” is really a fen. Fens are fed by groundwater while bogs receive water from rainfall.

Soon after settlers pushed into the Mad River Valley, they set about clearing timber and draining the great swamp. Ultimately, all but the 450-acres that comprise present-day Cedar Bog were destroyed, the once tremendous floristic diversity replaced by the ubiquitous fodder of America’s bread basket: corn, soybeans and wheat.

Well over 90% of Ohio’s peatlands that were documented post-settlement have been destroyed. Fortunately, conservationists were able to rally to protect what remained of Cedar Bog, and in 1942, the state provided funds for its purchase and the site was turned over to the Ohio Historical Society (now Ohio History Connection).

The National Park Service designated it a National Natural Landmark in 1967, and it was dedicated as a state nature preserve in 1979.

I’ve visited Cedar Bog scores of times, most recently on June 22. It was a special-event day, with Chelsea Gottfried, co-author of the book "Gardening for Moths," speaking about our nocturnal butterflies to about 55 people.

Shauna Weyrauch and I attended and arrived an hour early to explore the extensive boardwalk.

Immediately obvious upon entering Cedar Bog are the namesake white cedars. This is a northern tree, and Cedar Bog is the only wetland in Ohio dominated by white cedar. One must venture about 250 miles to the north before cedar “swamps” start to become common.

The bright orange flowers of Michigan lilies caught our eye. The spectacular plants are having a boom year and can’t be missed. Showy grass-pink orchids dotted the fen meadows, and there were large drifts of fen Indian plantain, a strange member of the sunflower family.

Brilliant magenta spikes of spotted phlox provided jots of color amongst the sedges, and we were pleased to see the wand lily in peak bloom. The latter sometimes goes by the name “death camas” due to its toxic alkaloids.

Cedar Bog hosts one of the highest densities of rare plants of any site in the state. Probably the most famous of these is the showy lady’s slipper, a huge orchid with massive pink and white flowers. There are only about five Ohio sites, and Cedar Bog is by far the largest. They’re through for the season, but plan on visiting late spring/early summer next year to see them at prime time.

Visitors are often surprised to see lizards racing along the boardwalk. They’re five-lined skinks and are common. So is America’s smallest dragonfly, the endangered elfin skimmer. It’s less than an inch in length and is a fen and bog specialist.

Elfin skimmers lurk in the sedges, along with a threatened damselfly, the seepage dancer. Sharp-eyed observers will find them right along the boardwalk.

Mark your calendar for July 6 when firefly expert Matthew Speights delivers a presentation followed by a nocturnal foray into the fen to see an amazing insectivorous lightshow.

Cedar Bog offers a portal into Ohio’s glacial past, without having to drive several hundred miles to the north.

A visit is always interesting and the dedicated volunteers and Maddie Brown, the site manager, are a wealth of information. For hours and other details, visit cedarbognp.org.

Confused Eusarca moths nectar at rare plant

Last Saturday evening, Cedar Bog hosted a moth night, headlined by speaker Chelsea Gottfried, coauthor of THIS BOOK. It was a great program, and Chelsea played to a packed house of about 55 people. Nightfall was settling in by the time her talk was done and illuminated mothing sheets had been strategically placed around the nature center.

I was equally interested in going into the heart of the large fen (Cedar "Bog" is actually a fen) and seeing what moths but by visiting the flowers in the fen meadows, many of which are rare in Ohio.

This is one of those rarities, the Wand Lily (Anticlea elegans), or as it is sometimes known, Death Camas. The latter stems from the toxicity of plants in this genus, and apparently the toxins are quite potent.

Shauna Weyrauch and I were more interested in moth flower visitors than plant toxicity on this night, but despite watching, saw no Lepidopteran visitors at the Wand Lily. I did later see an image from someone else of a moth nectaring at these flowers but could not tell what species from the image. I would have liked to have spent more time observing the Wand Lilies, but time was limited, and I thought that another species nearby would bear more mothy fruit.

This is Fen Indian-plantain (Arnoglossum plantagineum), and while quite the rarity in Ohio, there is plenty at Cedar Bog and it can form sizable drifts. It is a beautiful plant, and recognizing the family it belongs to as probably not intuitive for many people. Fen Indian-plantain, believe it or not, is a member of the massive Sunflower Family (Asteraceae).

It was in perfect bloom, and I figured that the luminescent white flowers would lure moths, so we spent much of our time observing the indian-plantain.

Bingo! A Confused Eusarca (Eusarca confusaria) taps nectar from the strange blooms. We saw a number of Confused Eusarcas doing so, as well as other moth species that I didn't manage photos of and did not identify. By the way, I do not know the story behind the "confused" part of the moth's moniker. They didn't look particularly confused to me, and I suspect it may have something to do with other similar species and humans' confusion over separating them.

Confused Eusarca caterpillars feed primarily on members of the Sunflower Family, and it may be that Fen Indian-plantain plays host to them. There are many other potential host plant candidates in Cedar Bog's meadows as well, and I would love to put in some more hours in the "bog" at night looking for nectaring moths.

If you want to experience Cedar Bog after dark, firefly expert Matthew Speights will be giving a program in the Cedar Bog visitor's center on July 6 at 730 pm. Afterwards, everyone will head afield to look for and learn about "lightning bugs". I can report that it looked like a laser light show in places last Saturday night due to prolific fireflies.

PHOTO NOTE: I have been regularly engaging in nocturnal photography for some time now and have hit upon a pretty bulletproof flash technique. It involves these settings: ISO 200, 1/200 second exposure, and f/13 or f/16 (a small aperture). The flash is either the Canon 600 EX II RT speedlite, or more commonly the Canon MT 26EX-RT Twinlites. The latter mount on a ring around the end of the lens barrel, and both lights - one on either side of the lens - can be adjusted independently. When the shutter is half tapped, subtle pre-lights come on on both flashes, providing enough light to focus. When the subject is locked on, fully depress the shutter and make the image. No need for clumsy flashlights or other auxiliary light sources to find and focus on the subject. my 100mm f/2.8L macro lens is the usual weapon of choice. With the flash set to TTL mode, it communicates with the camera and typically provides just about the perfect amount of light every time. I'd far rather focus on finding, approaching, and composing subjects that constantly fiddling with camera/flash settings. And light metering that I do is usually by adjusting the intensity of the flash itself, either adding or reducing light if needed.

Cedar Bog Moth Night: Saturday, June 22

 

A LeConte's Haploa (Haploa lecontei) at rest on the needles of White Cedar (Thuja occidentalis). I came across this moth last June 8, while on a whirlwind trip around Cedar Bog, near Urbana, Ohio, on my way home from elsewhere. I was especially pleased at this scene, as the moth chose the bog's namesake plant for its resting spot.

On Saturday, June 8, Chelsea Gottfried will give a talk about moths at Cedar Bog's visitor center. It is loosely based on the book that she and I coauthored, entitled Gardening for Moths. In addition to pragmatic information for anyone interested in growing native plants/moths (the two are inseparable), the book is full of natural history information about moths and their critical role in the environment.

The talk begins at 8 pm, and afterwards we'll have mothing stations up and running and luring lots of interesting moths. Visitors can see these fabulous creatures up close and personal and there should be plenty of great photo ops. For details, GO HERE.

Cedar Bog is an absolute goldmine of floral and faunal diversity and hosts one of the largest concentrations of rare species in Ohio. A few photos of some of the floristic gems (my main targets on that day) follow; all were made on my short June 8 visit.

If you would be interested in a special pre-talk hike around the bog, starting at 6:30 pm, led by myself and Chelsea, let me know. We'll probably limit it to a dozen people as the boardwalk limits the number of people who can gather as a group to look at and learn about interesting finds. Just send me an email if you're interested (jimmccormac35 AT gmail.com).

As always, click the photo to enlarge

A beautiful Grass-pink (Calopogon tuberosus) poses nicely for the camera. I especially appreciated its presentation of odd numbers: three flowers, and five buds above. Some stragglers may still be holding on for our moth night adventure next weekend. This orchid is pretty common in the fen meadows at Cedar Bog and is one of a number of orchid species that occurs there.

PHOTO NOTE: I made all of the images in this post with my Canon R5 (I can hardly bring myself to shoot with anything else, after much experience working with this amazing camera) and the Canon 400 DO II telephoto lens. I knew that at least some of my target plants would not be particularly close to the boardwalk - people should never leave the boardwalk - so I wanted much more reach than either of my macro lenses offer. The 400 DO II is a sensational lens that produces tack-sharp imagery, is very lightweight, has brilliant image stabilization for handholding, sports a relatively close minimum focus range but also works well with a 25mm extension tube for even closer focusing, and creates a wondrous bokeh. It and other larger telephotos can be fine, and even extraordinary, lenses for plant photography and I frequently employ them for such purposes.

The primary target of this day, the Purple Fringed Orchid (Platanthera psycodes). This is a very rare Ohio plant and is also very rare within Cedar Bog. Only two plants were found this year. Purple Fringed Orchid is a very striking plant, but can be easy to miss in shady, well-vegetated haunts such as at this site. This plant, and the other, were rather short in stature as well, making it even easier to miss them.

PHOTO NOTE: To get this image, I laid on the boardwalk and shot through the one small opening in the vegetation that offered an unobstructed view of the inflorescence. I had to push up against the kick rail on the far side of the boardwalk to get far enough away to focus, as my minimum focus distance (with the extension tube) was about 8 feet. Settings were ISO 1000, f/7.1, and 1/160 second exposure. The higher ISO (I typically prefer ISO 100-200 for plants) was necessitated by the darkish shaded habitat. Also, as I was handholding a bit higher ISO atones for any movement on my part as it permits a faster shutter speed than lower ISO settings would. Because of background clutter, I opted for a fairly open aperture of f/7.1 to better melt away the backdrop. In general, I prefer more open apertures for plants, often between f/4 and f/7.1. As for presentation, I chose to crop down to just the flowering portion of the inflorescence. After all, the incredible flowers are the most charismatic part of this orchid. Besides, the bottom portion of the plant had various stems and leaves of other plants in the way. No flash, and I'm tempted to add, "of course". I'm not a fan of flash on most plants, as it imparts a harshness and flatness that isn't pleasing to my eye. There are certain situations in which flash might help improve a plant image, but those instances are not typical.

Finally, the state-endangered Horned Bladderwort (Utricularia cornuta). This is one of Ohio's rarest plants, being found only at Cedar Bog and one other fen in a neighboring county. There are old records from two northeastern counties, but the bladderwort is no longer known to occur at those sites. Bladderworts are carnivorous plants, indeed, the largest group of botanical carnivores with some 250 species worldwide. Their root systems are beset with tiny sacs (the bladders) that have trap doors. When some tiny animal such as a water flea or insect larva swims near and triggers guard hairs on the bladder, the door pops open inwardly with great rapidity, sucking the victim inside. The door then rapidly shuts and over time the bladderwort ingests the soft parts of the prey, abetted by various enzymes that speed decomposition.

I was glad that I had the bigger lens for this one, as this bladderwort - the most unobstructed specimen that I could find - was probably 12-15 feet out in the meadow. The light was not exactly awesome, as it was afternoon with mostly bright sun. I hope to work more with this species in the future, and I think that I have more pleasingly illuminated shots than this from past work.

If you can make it out for our event next Saturday, we will see these species, sans the Purple Fringed Orchids which will probably be well past flowering - and MUCH more.

Rare plants of Cedar Bog

A meadow full of fen indian-plantain, Arnoglossum plantagineum. The plant is an odd member of the sunflower family (Asteraceae), and is quite rare in Ohio.

I'm giving a talk this Saturday, August 10th at Cedar Bog, a legendary botanical sweet spot that is full of rare flora - and fauna. The program commences at 10 am, and following that and lunch, we'll step out the back doors of the visitor's center and onto the boardwalk. An easy foray along the freshly rebuilt boardwalk will produce all manner of interesting flora (and fauna).

All are welcome. Cost is a mere $5.00 if a Cedar Bog Association member; if not, it's $10.00. The hard working members of the Association do nearly all of the heavy lifting in regards to management of this incredibly important natural area, and proceeds benefit their work. Details are RIGHT HERE.

The striking grass-pink orchid, Calopogon tuberosus, one of several rare orchids at the "bog". Cedar Bog, per square foot, has perhaps the richest botanical diversity of any site in Ohio. Many species of plants officially listed as endangered, threatened, or potentially threatened occur here. Even many of the plants that aren't listed as rare, at least in the fen meadows, are quite uncommon in the state.

Sedges drive much of the ecology at Cedar Bog - which is actually a fen. This one, seen here in full flower, is twig-rush, Cladium mariscoides. A close relative is the sawgrass of the Florida Everglades.

Wand-lily, Anticlea elegans, a highly poisonous member of the lily family. While you wouldn't want to eat it, the plant is nice to look at.

Seen here in fruit, prairie valerian, Valeriana edulis (syn: V. ciliata) is probably the rarest plant at Cedar Bog, and it has quite a story particularly insofar as this site goes.

If you can make it out, we'll have a good time and see lots of interesting stuff. Details about Cedar Bog are RIGHT HERE.

Five-lined skink

An extraordinary reptile, an older male five-lined skink, Eumeces fasciatus, basks atop the kickrail of the boardwalk at Cedar Bog in Champaign County, Ohio. When young, these lizards are prominently striped, don't yet have the orange head, and sport a conspicuous blue tail. With age, the stripes fade and the body turns a rich bronzy-brown, and that amazing orangish coloration develops.

Many a person has had their first exposure to a lizard (in Ohio!) at Cedar Bog. Five-lined skinks are common there, and frequent the boardwalk, or logs and stumps along the trail. Ohio is probably not considered a hotspot for lizards, but several species are locally common, including this one.

Five-lined skinks, like most of our other lizards, can be quite arboreal. I imaged this one on June 2, during a photography workshop at Cedar Bog led by Debbie DiCarlo and myself. It climbed high in a hackberry, pausing along the way to regard our group. The first image was shot the day before. This seems to be a very good year for skinks at the "bog", and if you go, you're probably going to see some. Along with scores of other interesting fauna, and flora.

Showy lady's-slippers nearing peak bloom!

Today was a gorgeous early summer day in central Ohio, and Debbie DiCarlo and I spent it teaching/guiding a photographic workshop at the incomparable Cedar Bog about 45 minutes west of Columbus. I've written about this place many times, as Cedar Bog is so rich in biodiversity. It's full of rarities, both plant and animal. There is always lots to see, especially this time of year, and the place is a photographer's dream. We had a wonderful group of eleven photographers today, and it's always rewarding to expose people to this gem of a place for the first time. Many wonderful photos were made at the bog on this day.

But one organism - a plant! - trumps all else, and it's nearing peak bloom now. I'd say mid to late this week the collective population will be at its best, and will still look good through the weekend and for a bit beyond. You'd do your inner psyche good to pay a visit, and be sure to take a camera. While the jumbo orchids will steal the show, there's tons of other stuff to see, including the very interesting five-lined skink. These lizards seem to be doing very well, and our group saw a number of them today.

Here's a photo of one of the numerous showy lady's-slippers, from today. Perhaps it can tide you over until you reach the bog yourself, to see it in person.

If you go, and I hope you do, be sure to support the nonprofit Cedar Bog Association, which does most of the heavy lifting in managing Cedar Bog, and providing tremendous public outreach. Among numerous accomplishments, they spearheaded the completion of an amazing new boardwalk last year. It's handicap-accessible and offers a way to commune with the bog without damaging the ecosystem, or getting your feet wet. Becoming a member would be a great way to support local conservation. GO HERE for more info.

Marsh-marigold

Marsh-marigold grows in profusion along the banks of Cedar Run. This brook is spring-fed and stays cool year-round. Water cress, Nasturtium officinale, grows in the stream's waters, and occasional clumps of giant-leaved skunk-cabbage, Symplocarpus foetidus, dot the banks. Cedar Bog, Champaign County, Ohio, yesterday.

Right now is about peak for marsh-marigold at Cedar Bog, but it should look good for the next week or so. It's well worth the trip. For more information about Cedar Bog, CLICK HERE.

Showy Lady's-slipper alert!

I (quite fortuitously!) had business at Cedar Bog today, and it just so happened to coincide with the blooming of what many would argue is North America's most spectacular orchid, the Showy Lady's-slipper, Cypripedium reginae. Needless to say, some effort was made to create imagery of these botanical wonders, and some results are printed here.

As spectacular as the lady's-slippers looked today, they'll look even better in a day or two, as many flowers were still in bud. And the plants should be remain looking good for another week or so, but this weekend will be the weekend to visit.

Now who would NOT want to see a botanical spectacle such as this?! Some of the older plants produce so many flowers that they resemble an orchidiferous shrub. Showy Lady's-slipper is listed as threatened in Ohio, and there are only about four or five populations in the state. Cedar Bog hosts the most plants, and they are also the most easily accessible ones.

I've written about Cedar Bog and its myriad charms many times, but of all its treasures these orchids are probably the most coveted by visitors. And as fate would have it, there will be an orchid walk this Saturday, June 4, at 2 pm. All are welcome, but note that there is a $5.00 admission charge to Cedar Bog. This place is one of Ohio's most special natural areas, and it is operated by the not-for-profit Cedar Bog Association. It takes funds to manage and maintain the site and the excellent education center, and the five bucks is a pittance to help support such a fine operation. In fact, I would highly encourage you to join the Cedar Bog Association as a member. It's inexpensive, and allows you to visit as often as you like.

Showy Lady's-slippers are botanical eye candy of the highest order. They're irresistible photo subjects, so be sure to take a camera when you go.

There's a mile long wooden boardwalk through the site, and visitors must remain on its planks. But there are plenty of orchids to be seen at close range, including this beautiful trio of plants. They are but a few feet from the walk. By Saturday, there will likely be five big pink and white flowers here - note the two whitish buds below the right and left flowers.

I hope you can work in a trip to Cedar Bog to see its spectacular orchids this Saturday, or sometime in the next week or so. It's near Urbana, and less than an hour's drive from Columbus. CLICK HERE for directions and other information.

Cedar Bog in winter

The meadows of Cedar Bog in a state of temporary dormancy, as seen last Sunday. I stopped by here on my way to Dayton and Aullwood Audubon Center, where I was slated to give a talk. While the vast majority of my many dozens of trips to Cedar Bog have been in warmer seasons, I like to occasionally stop by in the dead of winter. It gives one a broader sense of perspective to see these sites in all seasons. Come spring, Cedar Bog will burst to life in an explosion of flora and fauna. It is a must-see natural area.

At one point, this tiny Winter Wren popped out from under the boardwalk to regard me with bright curious eyes. He was no doubt hunting spiders and other such succulent fare in the sub-boardwalk's gloom. As if to help cast off fears that winter will never end, he flitted to a nearby root tangle and burst into song. The voice of a Winter Wren must be heard to be believed: a stunningly complex gushing aria that puts nearly all other North American birds to shame.

A brief ramble through the bog

I beached myself in Dayton, Ohio last night, arriving in the hometown of Orville and Wilbur Wright late in the evening following a trip to Indianapolis. Rather than punch through to Columbus, I figured I'd arise early and spend a few hours exploring one of my favorite places the next morning before returning home. Cedar Bog is located at 980 Woodburn Road, a few miles south of Urbana and an easy 45 minute drive from Columbus.

Everyone, and I mean everyone, needs to visit Cedar Bog. It is probably Ohio's most fabled natural area, and as we shall see, interesting life forms abound. It isn't really a bog - it's a fen! - but let's not belabor ourselves with details. I've written about this place numerous times. If you scroll down the alphabetized list of subject matter on the right side of this page, and click on Cedar Bog, you'll see those past posts.

While driving down the entrance drive to Cedar Bog, I heard birds galore, even this late in the season. I noticed a pair of busybody House Wrens had occupied a martin house and were working on cranking out a second brood. Nearby Black Cherry trees dripped with ripe fruit, and Gray Catbirds and Cedar Waxwings were sneaking about plundering the trees' larder. A Yellow-billed Cuckoo yelped mournfully in the distance, Eastern Kingbirds teed up on snags, and further down the boardwalk an Eastern Screech-Owl whistled away, forgetting its nocturnal habits momentarily.

As I worked at photographing the wrens, I noticed this battle-weary Eastern Tiger Swallowtail. Given the frayed and tattered condition of her wings, it's amazing she can still fly. Nonetheless, the butterfly hopped energetically about the flowers of Prairie-dock, Silphium terebinthinaceum, avidly seeking nectar.

Although I don't directly feature any in this post, Cedar Bog is incredibly rich in plant diversity. In fact, one could argue that it hosts the richest plant diversity of any comparably sized site in Ohio. There are scores of rare species, and when one gazes over one of the fen meadows, most of the plants in view are rare in the state.

Butterfly numbers and diversity were exceptional on this rather hot and muggy day. I enjoyed watching this male Zabulon Skipper as it used the flowers of a Spiked Blazing-star, Liatris spicata, as a perch. Any other butterfly that dared fly too close was aggressively chased - the "Zab" was probably hoping one of them would prove to be a female of his kind.

Common Wood-Nymphs, Cercyonis pegala, were everywhere. These largish butterflies often stay low in the grasses and sedges, thus I was pleased when one chose to rest briefly on the colorful flowers of a blazing-star.

The vining Virgin's-bower, Clematis virginiana, was in full bloom and I always give more than passing attention to the flowers. It paid off as I was rewarded with this tiny day-flying moth. It is a Spotted Thyris, Thyris maculata, and in this case the nut does not fall far from the tree. A major - if not THE major - host for this species is plants on the genus Clematis. The moths are easily missed as they bear an astonishing resemblance to bits of dead plant debris.

Never to be ignored are Cedar Bog's two rarest Odonates. This one is a male Seepage Dancer damselfly, Argia bipunctulata, and they are having a great year. I saw scores throughout the open fen meadows. Common as it may be at Cedar Bog, there are few populations in Ohio and Seepage Dancer is listed as endangered.

The other endangered dragonfly is the Elfin Skimmer, Nannothemis bella. I find them much scarcer than the previous species, and generally much harder to find and photograph. This is the male, resplendent in a coat of powder-blue. The female looks entirely different - black and yellowish striped, and quite wasplike in appearance. These truly elfin dragonflies are so small that the uninitiated, if they noticed them at all, would almost certainly not recognize the skimmers as dragonflies.

I was pleased to see a number of Phantom Craneflies (genus Bittacomorpha) flying about in the shady gloom of the swamp forest areas. Their wafting, buoyant flight is aided by tibial flanges that give them more lift. Seeing one in flight is a mind-bending experience. It resembles a flying kaleidoscope, but its blanco-negro patterning is excellent disruptive coloration and the insect quickly "disappears" when it enters the shadows. I would have liked to work them harder for photos, but the mosquitos drove me out. Take bug spray when exploring Cedar Bog. Although, the open fen meadows were not mosquito-plagued at all - only the shady wet woods.

After my two hours were up and I was packing away gear in the car, I took a glance at a patch of prairie plants near the parking lot. There sat a gorgeous Gray Treefrog, Hyla versicolor. I find these small treefrogs irresistible subjects, so out came the camera again. This has been a boom year for treefrogs, perhaps because of all the rain.

So, all that and much more in a brief few hour ramble down Cedar Bog's boardwalk. The place never fails to provide interesting subjects.

Bugs in the Bog

Yesterday dawned clear and crisp; a picture-perfect early summer day. A good day indeed to head to one of my favorite natural areas, the legendary Cedar Bog near Urbana, Ohio. I was there to give a lecture on entomology, specifically about the "bugs" of Cedar Bog. The best part of the day was the special off-the-boardwalk field trips before and after the talk.

Venturing off the mile-long boardwalk that bisects Cedar Bog's fen meadows and various other habitats is strictly taboo. Only permitted researchers or others affiliated with the bog may do so, and even then off boardwalk travels are rare. Our groups consisted of noteworthy supporters of the bog, and we wanted to thank them for their contributions with a special trip.

One of our groups deep within the bog (which of course is really a fen), in a very special meadow. I should say that, even though venturing far off the boardwalk was a treat for these folks, most people probably wouldn't want to do this. The ground is spongy, and a misstep can land one in boot-sucking quagmires. There is a lot of dense brush to push through, the humidity is intense, and ticks, mosquitoes  and other pests can abound.

But by braving all of that, we got to see a lot of interesting flora and fauna. This particular meadow is distinguished by the presence of one of Ohio's rarest plants, the prairie valerian, Valeriana ciliata. I wrote a bit more about this plant RIGHT HERE.

Try as we might, we could not completely ignore the non six-legged crowd. This is an adult five-lined skink, Eumeces fasciatus, and many people first learn that lizards do indeed occur in Ohio by spotting one of these along Cedar Bog's boardwalk.

If you are smaller than the owner of this eye, you would not want to get caught in its harsh unblinking gaze.

The previous multi-faceted eye doesn't miss a trick, and it belongs to this utterly ferocious beast. This is a large robberfly, Laphria thoracica, that is an excellent bumblebee mimic.They sit atop leaves, and wait for potential victims to fly by. The fly then scrambles out, and envelops the lesser insect with its legs, then stabs it with a proboscis that resembles a hypodermic needle. Chemicals are injected that liquefy the victim's innards, which the robberfly then sucks out via its proboscis.

Almost as if on cue, this enormous gray petaltail, Tachopteryx thoreyi, appeared in one of the meadows. Petaltails are our most primitive dragonfly, and are brutish animals. They'll capture and eat dragonflies up to their own size, including other petaltails. They seem especially fond of bagging swallowtail butterflies. Shortly after I made this photo, the petaltail shot over and landed on my arm, giving the group a great look. You can find a more detailed post about these fascinating dragonflies RIGHT HERE.

Every meadow had its complement of painted skimmers, Libellula semifasciata. It must be a good year for these stunning dragonflies. I've never seen so many in a single year, and have seen many other reports of them from around the state.

We were quite excited to find a brown spiketail, Cordulegaster bilineata, and the animal had the good manners to pose obligingly. At one point, it slowly hovered and flew right among the group, offering stunning looks. All too often with big dragonflies, one is left with far less than satisfactory looks and no photo opportunities. We saw at least a half-dozen massive swamp darners - proportionately probably our largest dragonflies - but none of them cooperated for photos or close looks.

This female violet dancer, Argia fumipennis, is making mincemeat of a victim. You can see the shiny wing of its prey, which might be some type of winged ant.

The meadows were awash with this interesting moth, the Le Conte's haploa, Haploa leconteii.They look rather butterflylike when in flight, and make no great effort to hide themselves when they alight.

We encountered a sapling that was covered with these interesting insects. They are treehoppers, in the nymph stage. A greenish-white freshly molted nymph is in the center of the photo. I found these treehoppers to be quite showy with their chestnut eyes, stegosaurus spines along the back, and odd little hornlike helmets. I don't know the species, but many treehoppers take on the appearance of thorns or other plant parts, which helps them blend in when at rest. They tap sap from their host plants, and treehopper colonies are often attended by ants, which feed on the honeydew secreted by the treehoppers.

As the sun faded to the west towards the day's end, it cast perfect light to reflect the shadows of water striders in Cedar Run. The crystal clear water of the small creek allows the shadow of the strider to be seen on the stream bottom. Water striders (this one is probably in the genus Gerris) do not break the water's surface, but their feet create hydrological "divots" on the water's surface. It's these divots that we're seeing reflected by the shadows, with the insect's slender ellipsoid body in the center.

All in all, an excellent day at Cedar Bog, filled with interesting finds. If you haven't visited Cedar Bog, please do. CLICK HERE for details.
