20 THE DAVEY BULLETIN | September/October 2021 EAST CAMPUS TREE PLANTING SUPPORTS FUTURE RESEARCH The honey locust trees were selected because they are a popular landscape tree and has pests suitable for research purposes. This tree is also a favorite of Dan Herms because he studied honey locust pests for his master's degree, so he has knowledge about this species. River birch trees have interesting growing habits because they flush leaves throughout the growing season. This makes them sensitive to environmental factors. The crab apples are moderately disease resistant and may be used to perform apple scab research. "The main focus right now is getting these newly planted trees established before research experiments can begin," said Dan Herms, vice president of research and development. In the future, other trees for research purposes will be planted. "We have a list of about 10 species that have varying physiological characteristics that will make them useful for research models," Herms said. "In the arboretum planned for the East Campus, for example, there will be a climate change garden where we will plant zone 6 and zone 7 species, which are not historically winter hardy in Northeast Ohio, to illustrate how the hardiness zones are shifting." EXPERTISE Over 200 trees were planted this summer at Davey's East Campus to be used for future randomized research experiments by the Davey Institute. This planting is part of a multi-phase planting plan to occur over the course of the development of the East Campus, which is located across from the corporate office in Kent. A team from the Davey Nursery planted the trees. The tree species are mugo pines, river birch, honey locust and crab apple trees. Eventually, the trees will be used for plant health care, soil management, water management, nutrient management, insect/disease control and drought stress research experiments.
