Sally Weeks was born and grew up on a dairy farm near Winamac, Indiana. She received a BSF in Wildlife Management and an MS in Forestry from Purdue's Department of Forestry and Natural Resources, where she has taught aspects of tree identification for twenty-five years. Harmon P. Weeks, Jr., is a professor of Wildlife Science in Forestry and Natural Resources at Purdue University, and has taught Habitat Management for thirty-five years. George Parker is Professor Emeritus of Forestry and Natural Resources at Purdue University and studied old growth forests and the dynamics of forest communities.
All at the forestry and natural resources department at Purdue University, Weeks (tree identification), Harmon P. Weeks (habitat management), and George Parker (emeritus, old-growth forests) expand the 2005 first edition to include 12 non-native species that have become problematic, and may be confused with natives. Some of the information is corrected or updated and some new photographs added. The keys have also been revised to incorporate the new species. An illustrated glossary is provided. Conifers come first, then hardwoods, and finally introduced species. Range maps and color photographs of identifying features accompany text on form and size, habitat, wildlife uses, landscaping value, and similar species. (AnnotationC2011 Book News Inc. Portland, OR)
