Identifying Hardwoods Growing on Pine Sites

Identifying Hardwoods Growing on Pine Sites

About the author

Harold E. Grelen was a U.S. Forest Service scientist whose work focused on southern forests, especially the plants and understory communities found in longleaf pine and pine-hardwood landscapes. In Identifying Hardwoods Growing on Pine Sites (1977), he is credited as Principal Range Scientist with the Southern Forest Experiment Station in Pineville, Louisiana.

He wrote or co-wrote several practical research publications, including Common Herbaceous Plants of Southern Forest Range (1984) with Ralph H. Hughes and Common Plants of Longleaf Pine-Bluestem Range. His books were designed as working guides, pairing descriptions and illustrations with field-ready identification help for species important to forestry, grazing, and wildlife management.

Though not a household-name nature writer, Grelen's publications have had a long afterlife because of their clarity and usefulness. They remain valuable for readers interested in botany, forest ecology, and the everyday craft of recognizing plants in the American South.
