Why This Research is Important

Invasive plants, insects, and diseases are changing forest often by  damaging or killing individual trees, and these impacts are expected to increase in the future.   Understanding the genetics of resistance to invasive pests and how it is inherited helps foresters understand if trees may adapt over time.   Utilizing resistance in tree breeding programs may allow foresters to preserve or accelerate the recovery of threatened tree species.
