This is an annotated list of some of my favorite natural history resources, with a focus on Indiana. The vast array of life forms and interesting places described in these works might make a person wish for several lifetimes, just to study and explore them all. In the meantime, new work keeps appearing, and no doubt I’ve missed many notable contributions, but I recommend anything that appears below. All are worthy additions to an Indiana naturalist’s toolkit. I do not receive any compensation for linking to or Amazon; those links are provided entirely for your convenience.

ACRES Land Trust operates mostly in northeastern Indiana. ACRES publishes The ACRES Quarterly, a small format, full color newsletter that covers their latest doings, upcoming events, property profiles, and often historical information about past acquisitions. Their website, at, is a treasure trove of maps and information about their properties. Also available is the ACRES Land Trust Preserve Guide, (revised periodically) which contains profiles, driving directions, and maps of many of their preserves, arranged by county.

Cummings, Kevin S., and Christine A. Mayer. 1992. Field Guide to Freshwater Mussels of the Midwest. ISBN 1882932005. A small but intriguing volume. Each species gets two pages – one of descriptive text, facing a second with one or more color photos and a range map. [Amazon]

Profusely illustrated with gorgeous color photographs and range maps, this volume also includes in-depth treatment of many species, with Indiana-specific details not readily available anywhere else.

DeLorme. Indiana Atlas and Gazetteer. 1998. I wish this atlas received more frequent updates, but as there’s nothing else remotely like it, it goes along with me on all my trips in search of Indiana’s wild areas.

Eastman, John. Eastman’s books, superbly illustrated by Amelia Hansen, don’t pretend to describe every species you’re likely to encounter in the habitat types they cover. Instead, these volumes dig deep, providing fascinating details on many of the most common, significant, and/or interesting species. I know of three:

This is the earliest thorough survey of Indiana’s natural areas and was a truly groundbreaking effort. A half century later, some of the places it describes are long gone, but many old friends remain. [Amazon]

McPherson, Alan. Alan McPherson deserves special mention for his incredible work in making information about the natural areas of Indiana available to the public. I have no idea how he managed to learn about, find, and explore so many places, then produce a series of exhaustively thorough books detailing what he found. We are all richer for his work.

They’re all here, described and illustrated in this first-rate book, along with many pages describing various aspects of butterfly natural history. [ or Amazon]
