If you hike in Ohio, sooner or later you'll run into poison ivy or poison sumac. Probably sooner than later. They produce an irritating resin called urushiol that can produce a strong allergic reaction on contact in most people. The resin is found in all portions of the plant. Merely touching the plant can result in a rash and blisters within a few days.

Seip Mound State Memorial Park is one of the five noncontiguous sites that make up the Hopewell Culture National Historical Park. The other four sites are Hopeton Earthworks, Hopewell Mound Group, High Banks Works, and the Mound City Group (reviewed by us here). Native Americans belonging to the Hopewell tradition constructed this mound sometime between 100 B.C. – A.D. 400.
The mound pictured above was part of a larger earthworks complex. At a number of sites in Ohio, Native Americans 
In the following post, I note the distinguishing characteristics of Ohio's turtle species, plus the counties in which they've been sighted.
Family Emydidae
Midland Painted Turtle (Chrysemys picta marginata)
If you've seen a turtle basking in the sun in Ohio, and you're wondering what kind of turtle it is, the odds are that it's a Midland Painted Turtle.
This is one of the most common turtles in Ohio, plus it's easy to spot because it enjoys basking on logs or other objects 
In science fiction, there's something called "terraforming" where people take an inhospitable, alien habitat and make it more earth-like so that people can live there. Well it turns out that sphagnum moss has mastered something similar -- I'm going to call it "boggaforming" -- where it takes a wetland and makes it more and more bog-like. One its secret weapons in this process is dead sphagnum moss. Here are some of the ways that previous generations of sphagnum moss contribute to the success of the 
Previously I've pointed out that Jackson Bog and Cedar Bog aren't really bogs. Now it's time to look at a nature preserve that really is the bog that it claims to be: Cranberry Bog State Nature Preserve. However it's not like any other bog in the world since the entire bog is floating in the middle of a lake.
Here's what happened. For thousands of years Cranberry Bog was an ordinary bog located in what came to be known as Big Swamp. In 1830 Ohio decided to build a dyke in Big Swamp 
Cedar Bog is a state nature preserve that's managed by the Ohio Historical Society due to its historical significance... or should I say prehistorical significance? There are a number of plants and animals in the preserve that were common in this region at the close of the last Ice Age, but which are now found in cooler, North American climates. Because it is such a unique habitat, in 1941 it was the first nature preserve designated by Ohio. Today it is one of Ohio's 25 National Natural Landmarks.

Hoover Mudflats Boardwalk is part of the Hoover Nature Preserve operated by the Columbus Parks and Recreation Department. It is one of the best birding sites in central Ohio. In the fall the city lowers the water level in Hoover Reservoir, so it's more hospitable to migrating shore birds. The area around the boardwalk is also used for fishing and launching kayaks, and I've seen crew teams training here. Beyond that, the site is just lovely.

When I caught sight of this turtle trailing a skirt of algae, I was immediately reminded of the similar turtles that are often depicted in Asian art.
In China such a turtle is supposed be one of four sacred animals: the turtle, the tiger (or kirin or rhino), the dragon, and the phoenix. The Japanese adopted the mythos surrounding the sacred turtle whom they refer to as the minogame. Not every turtle gets to become a minogame, just the lucky ones who have been blessed with long 
This is follow-up to my earlier post, I sold a photo!. I knew that one of my photos was going to be used as a background image on an interpretive sign. But I just learned from my contact person with Bluestone + Associates that the sign was installed this month at Klehm Arboretum and Botanic Garden.
Since the arboretum is in Illinois, it wasn't likely that I'd ever see it myself. What a happy surprise it was to receive photos of the sign once it had been installed. It was 
Since we were at Scioto Trail State Park mid-May, there were so many wildflowers along the trails that I thought they merited their own post. Here's a look at some of the flowers that we saw, plus some of the living creatures that were near them.

While looking for wildflowers, the following little creatures also caught my eye.
