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.

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)

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

I selected a representative photo, but be aware that there can be a lot of variation in color for frogs of the same species. Below each photo, I note the range of colors that are possible for that species.
