Ash trees may be more resilient to warming climate than previously believed

January 26, 2022

Since the 1990s, scientists have been predicting that North American tree species will disappear from portions of their ranges within the next 50 to 100 years because of projected changes in climate. A new study led by Penn State forest biologists found that when transplanted to warmer environments, ash trees can survive increased temperatures of 7 degrees Fahrenheit and sometimes even up to 18 degrees Fahrenheit, suggesting that these trees may be more resilient to climate warming than previously believed.
