Non-native invasive insects and pathogens are causing significant ecological damage to forests worldwide. Numerous genetic resistance programs have been established to identify and/or develop populations of tree species with resistance to their respective pests and pathogens. These projects involve finding individuals with natural resistance to the disease of interest, and/or introducing resistance to populations through breeding.

Once populations of insect/disease resistant trees are developed, the next component is reintroducing those trees back into the landscape. This is a tremendous effort that requires understanding how to match the ecology of the tree species with management of the planting site. The Northern Research Station has scientists involved in all aspects of species restoration, working with numerous tree species, including American elm, American chestnut, several ash species, and more. The goal is to bring these species back to facilitate the recovery of healthy forests.

Season 2: Backcross examines tree breeding and selection to promote resistance to invasive insects and diseases.
