Ohio taxpayers can opt to support state nature preserves

Irwin Prairie near Toledo, one of Ohio's rarest habitats

From a natural-history perspective, Ohio is a crossroads state. Major ecosystems collide here, creating a cornucopia of biodiversity unlike any other Midwestern political region.
The fourth-largest Great Lake, Erie, forms Ohio’s northern border. This grand inland sea brings a wealth of flora and fauna, some of it unique to the state.

Boreal habitats normally found far to the north provide a glimpse into our recent glacial history. The ecological footprints of a frigid history can be found in relict bogs, fens and hemlock ravines.

The majesty of the Appalachian Mountains sweeps into Ohio from the east, impressing with rugged forested terrain. Spectacular rock formations and deep gorges harbor a beauty that contradicts outsiders’ superficial impression of this “rust belt” area.

Four hundred and fifty one miles of the Ohio River, one of America’s mightiest streams, delineates
our southern boundary. The river’s broad valley brings a taste of the south. Southern plants such as mistletoe, cross vine, and purple passionflower reach their northern limits on the Ohio side of the stream.

During the hotter, drier xerothermic period, about 5,000 years ago, Great Plains prairies expanded east. These rich grasslands largely petered out in what is now Ohio, and at the time of European settlement, prairie covered nearly 5 percent of the state.
When Ohio was granted statehood on March 1, 1803, the newly minted Buckeye State was home to about 45,000 people. Today, there are more than 11.5 million Buckeyes. Such astronomical growth put tremendous pressure on our habitats, and much was lost before anyone thought to protect it.
On Aug. 31, 1970, the Ohio legislature established the Division of Natural Areas and Preserves as part of the Ohio Department of Natural Resources. Its mission: identify and protect the best of Ohio’s remaining habitats.
Today, the division owns or manages a system of nearly 140 state nature preserves. Many of them, such as Clifton Gorge, Conkles Hollow and Sheldon Marsh, are popular and heavily visited. Scores of others are largely off the radar screen. They all share a common denominator — protecting the best of the best and the rarest of the rare.
Irwin Prairie, a preserve in the Oak Openings just west of Toledo, is an excellent example of the value of our natural-areas program. Irwin preserves one of the only remaining examples of imperiled wet prairie habitat. The 207-acre preserve is incredibly rich in flora and fauna, including many rare species. A boardwalk allows easy access.
Protecting plant life is at the core of conservation, and the Division of Natural Areas and Preserves excels at this. Probably 90-plus of Ohio’s roughly 1,800 native plant species are safeguarded in the collective of state nature preserves. Plant diversity spawns animal diversity. I think that conservation of the state’s natural resources is important to most Ohioans.
There’s an easy way to support stewardship of our state nature preserves. Tax day quickly approaches, and your state income-tax form has an easy checkoff option that allows filers to donate a portion of refunds to “natural areas.” It will be money well-spent.
Make time to visit one of your state nature preserves. More information can be found at:

The Pinching Beetle, a rather brutish looking bug

The world is awash in beetles, and they come in all shapes and sizes. Few of them can match the intimidation factor of a Pinching Beetle, Lucanus capreolus, though. Those formidable looking mandibles look like they could slice off a finger.

Today was one of those coolly diverse days. I started off down in Fayette County, visiting the farm of a friend. He has restored about 25 acres of wetlands, and the response by the animal community has been nothing short of phenomenal. Blizzards of dragonflies of many species, amphibians galore, and nesting Blue-winged Teal, Pied-billed Grebe, and Sora. Among MANY other things. And all in a short two years. Add water and they will come.

Then, working my way home, I ducked into a Madison County cemetery that has a thriving population of Thirteen-lined Ground Squirrels, and shot images of our native prairie dog. Then, I stopped at a spot along Little Darby Creek, waded on in, and procured some pretty nice shots of various stream bluets and dancers. …

Calliope Hummingbird in central Ohio!

A hatch-year male Calliope Hummingbird strikes a pose. Small but tough, the hummingbird was feeding actively yesterday in 39 F temperatures. It frequents feeders and gardens at a home in Delaware County, Ohio, about a half-hour north of Columbus.

Fortunately, the wayward hummer appeared at the home of Tania and Corey Perry. Tania is a birder, and knew right away that the hummingbird was something special. For a while, the identification was up in the air, which isn't surprising. The Calliope Hummingbird used to be placed in its own genus, Stellula, but has recently been submerged into the genus Selasphorus, which includes Allen's, Broad-tailed, and Rufous hummingbirds. The latter two, especially, are quite similar to the Calliope in subadult plumage. Rufous is the default "vagrant" hummingbird here, with dozens of records and birds turning up annually. There is but one Ohio record of Allen's Hummingbird, from late fall/early winter 2009. Ditto the Calliope Hummi…

Snowy owl photography tactics - and things NOT to do

A gorgeous juvenile female snowy owl briefly catches your narrator with its piercing gaze. It's doing its Linda Blair/Exorcist trick - twisting its head 180 degrees to look straight behind. Owls have 14 neck vertebrae - double our number - which allows them such flexibility.

These visitors from the high arctic have irrupted big time into Ohio and adjacent regions, with new birds coming to light nearly every day. Probably 80 or so have thus far been reported in the state, and some of them have stuck around favored spots and become local celebrities.

I went to visit one of these birds this morning - the animal above, which was found last Friday by Doug Overacker and Julie Karlson at C.J. Brown Reservoir near Springfield. In the four days since its discovery, many people have visited as is nearly always the case when one of these white wonders appears near a large population center or is otherwise very accessible.

And as is always the case, people want to photograph the owls. And th…
