Episode notes
Hardier Fraser Firs Are Coming
- North Carolina State researchers developed a new Fraser fir that grows faster and holds needles longer.
- They aim to breed trees that better withstand warming, pests, and disease.
Decades To Breed The First Seed
- Justin Whitehill says the first generation of seed took 25–30 years to develop.
- He notes the work began before climate change, pests, and disease intensified.
Elevation And Warming Stress Fraser Firs
- Fraser firs naturally grow at high Appalachian elevations but most farms are lower and warmer.
- Lower elevation farms stress trees and rising temperatures increase vulnerability to pests and disease.
