David A. Landes Discusses various wildlife of the American Midwest and other related topics. Here I wish to showcase several of my scientific publications. A., J. H. Hunt, and A.

I also wish to share my devout enthusiasm for the preservation of our native species (and have this serve as a mini bulletin on native wildlife of the Midwest region). Other topics connected with our regional natural heritage are included. Publications:

Not only do we have flying squirrels in Wisconsin, but there are two different species found here!

The Northern flying squirrel (Glaucomys sabrinus), pictured here, is a special concern species and a legally protected wild animal. They only live in the northern parts of the state in conifer and mixed hardwood forests.

The Southern flying squirrel (Glaucomys volans) is found throughout the state and is also a protected wild animal. They can be distinguished from their northern counterpart by having completely white belly fur in addition to being a smaller and weighing less.

While southern flying squirrels are more common, it’s rare to see either species because they are completely nocturnal. While they don’t actually fly, the loose fold of skin on both sides of their body running from their ankle to their wrist allows them to glide from tree to tree. A typical flight (glide) is 50-60 feet.

Special concern species are those with suspected declining populations where more information is needed. Conservation of these species as well as those that are threatened or endangered is supported, in part, by donations to the Endangered Resources Fund.

Things that make you go hmmm? For weeks I have been staring at this one mullien plant across from the entrance to Marais Des Cygnes. Reasons for an odd stalk can be chemical, physical (searching for sun, animal damage), or genetic. The right angles on this one are odd though, like some critter designed a perfect perch.
