Breeding programs are an important tool for managing invasive insects and diseases causing high mortality rates and even threatening extinction of some of our forest tree species. The emerald ash borer (EAB) invasion of North America, as one example, has resulted in five North American ash species being listed as "critically endangered" on the IUCN red list (IUCNredlist.org). Impacts from such significant losses are far-reaching. Wildlife species that depend on threatened tree species can also be at risk of extinction, Mortality of riparian tree species such as Eastern hemlock, currently under attack by the hemlock woolly adelgid, can impact water quality. Economic impacts can be far-reaching, and include the costs of removing and replacing trees, and the loss of valuable income sources. This income loss is especially pertinent to rural communities reliant on both traditional – such as lumber, pulp, paper, and fiber and non-traditional forest products – ginseng, morels, and goldenseal. Additionally integral to rural economies are recreational opportunities provided by healthy forests, such as camping, hiking, canoeing, kayaking, hunting and fishing. In Hocking County, Ohio, for example, recreational tourism supports one out of every seven jobs and generates more than 115 million dollars annually (Apsley et al. 2014). Hemlock trees are cornerstone species in these recreation areas and their loss due to hemlock Wooly Adelgid (HWA) pose a serious threat to local communities.
