Backcross American chestnut seedling planting

On May 31 Carroll Ritter and Glenn Kotnik planted backcross American chestnut seedlings in clearings in a mature forest in southeastern Indiana. The forest is about 80 acres in size and has been preserved from cutting and handed down through many generations of a single family. The predominant tree species is black walnut,  many of which are 2 feet in diameter. Other species include tulip (Liriodendron tulipifera), black cherry and pawpaw. Ash trees were present but have died due to the emerald ash borer. Death of ash trees created clearings in the canopy and it was felt that this would be a good opportunity to introduce American chestnut as a replacement species.

The chestnuts were planted with galvanized steel fencing around each to protect the seedlings from deer.

Join us on tomorrow, October 10, 2025, from 11:30AM – 1:00PM (EPT), for the next LIVE Chestnut Chat.

Our special guest, Dr. Trevor Walker, Assistant Professor of Forest Genetics and Co-Director of the Cooperative Tree Improvement Program at NC State University, will share insights from 70 years of breeding loblolly pine for disease resistance, growth, and stem form. He will also consider which practices are likely to succeed for American chestnut, which are not, and why.

Great presentation!

🌰 Harvest season at TACF’s Meadowview Research Farms brings both beauty and breakthrough science. Many of the chestnut crosses we gather are generated through recurrent genomic selection—cutting-edge research driving restoration forward. Each bur holds not only the wonder of new life, but also the promise of a future where the majestic American chestnut returns to our forests. 🌳
