Flora and Fauna of Appalachia, and Andrew Gibson of The Natural Treasures of Ohio. While most of my former students tend to be more wildlife oriented, Mike and Andy have quite the affinity for the botanical world.
Ohio Birds and Biodiversity. Here is Jim doing what he does best, getting down and dirty. Perhaps I should say getting down and wet at McCraken Fen. I believe he was after some damselflies at this time.
Zen Through a Lens. She has been doing a lot of portrait pictures of late. Examples of her other work are linked at her blog website.
Wahkeena Nature Preserve. Robyn and Tom Shisler have provided excellent information and locations at Wahkeena for studying moths, other insects, wildflowers, ferns, and you name it.
Muskingum Watershed Conservancy.
Jim McCormac has posted articles before on the idea that many species of plants, insects, birds, and other organisms seem to be extending their range northward.
