University of Kentucky Arboretum

The research was performed at the University of Kentucky. It has been investigated since 1940. In 1968, the Natural Resources Conservative Service of the US Department of agriculture mapped the soil as mostly Maury silt loam. A recent mapping redefined the soil as a mixture of Maury and Bluegrass. They found the Arboretum is dominated by black walnut in the canopy and hackberry in the sub-canopy. These trees are native to the area but there are plants such as the yellow poplar that are native to the region but were planted in the arboretum in the 1950s. Also in the 1950s the Forestry Department at the University of Kentucky put up a fence to exclude cattle and also be able to track undisturbed growth. The fence was a woven wire and 1.5 m high, there have been no deer in the Arboretum for almost a century. In the 1990s nonnative shrubs were eliminated, Lonicera maackii and Euonymus alatus.
