The Mammals of Washtenaw County, Michigan Occasional Papers of the Museum of Zoology, No. 123

"The Mammals of Washtenaw County, Michigan" by Norman Asa Wood, is a detailed study from the early 1900s exploring the different types of mammals living in Washtenaw County, Michigan; it shows us where they lived and how their environment was changed by people moving in and cutting down forests. The text looks closely at many mammal types, showing which ones were found in areas like the Interlobate Lake District and the Lake Plain District, demonstrating how the arrival of early settlers hurt the bigger populations like deer and wolves, while the smaller animals such as skunks and ground squirrels managed to flourish. The book is based on many observations and stories from people who lived there at the time, offering a close and historical look at the local wildlife during a time of major transformation.
