Review of This Land: A Guide to Central National Forests by Robert H. Mohlenbrock

Robert Mohlenbrock's guide to the national forests of the central U.S. provides the traveling naturalist with a wealth of information on the wide array of national forest lands in the heart of the country. Part of a three-volume series of field guides, this volume covers the states of Louisiana, Minnesota, Missouri, Montana, Nebraska, New Mexico, South Dakota, Texas, and Wyoming. While most of the forests are along the western and eastern borders of the Great Plains, readers will find a detailed travelog for a National Forest within a day's drive of most areas within the region. While not the focus of this volume, a brief mention of the National Grasslands of the Great Plains would have made it more comprehensive for the traveling naturalist.
