Did you know?

HTIRC breeding program plant materials are available to the public from two sources starting in spring 2025. Some of this material was selected for stem straightness and growth rate and is under continuous improvement as breeders remove underperforming clones and seedlings from seed production areas. The HTIRC has also been working to preserve and develop disease-resistant populations of two endangered native fine hardwood species – butternut and American chestnut.

Seedlings can be ordered from:

• Indiana DNR Division of Forestry tree seedling nursery sells bare root select tree seedlings for conservation plantings in Indiana. Species include black walnut, red oak, white oak, and black cherry. https://www.in.gov/dnr/forestry/tree-seedling-nurseries/
• Tree Pro distributes bare root seedlings of six species across its timber select, conservation and wildlife lines. Timber select varieties will include black walnut, black cherry, northern red oak, white oak and pure and hybrid butternut. Conservation species include pure butternut and American chestnut. The wildlife line will feature select precocious white oak. https://www.treepro.com/collections/purdue-timber-select-series

How Can I Get Involved with HTIRC?

• Do you have property you would like to donate or to allow HTIRC to utilize for research?
• Do you have ideas for research projects that could help advance the science and application of tree improvement, management and protection of hardwood forests, especially as they related to tree breeding, tree nursery practices, tree plantation establishment and management and silvicultural systems in the Central Hardwood Forest Region?

If so, let us know at htirc@htirc.org or 765-496-7251.
