The HTIRC conducts research in several well-equipped laboratories located on the Purdue University, West Lafayette, Indiana campus. Most are located in the David C. Pfendler Hall of Agriculture.
The HTIRC has numerous research locations dedicated to improvement of hardwood trees and forests. Many of our research areas are located on Purdue University properties. Cooperating organizations and individuals have provided locations across the Central Hardwoods Region, allowing HTIRC to conduct research across a wide range of sites. Our tree breeding program alone involves over 180 test plots at over 40 sites around the nation.
The Department of Forestry & Natural Resources owns and manages over 5,000 acres on properties located throughout the State of Indiana to provide opportunities for research, extension, and education.”
Research Publications
The Hardwood Tree Improvement and Regeneration Center (HTIRC) maintains a comprehensive repository of research publications focusing on hardwood tree genetics, forest management, and related ecological studies. These publications, authored by HTIRC researchers and collaborators, encompass a wide range of topics, including:
-
Forest Ecology and Management: Studies on forest dynamics, biodiversity, and the impact of climate change on forest ecosystems.
-
Genetic Improvement: Research aimed at enhancing disease resistance and growth characteristics in hardwood species such as black walnut, butternut, and American chestnut.
-
Remote Sensing and Technological Innovations: Development and application of advanced technologies like LiDAR and UAV imagery for forest inventory and monitoring.
