Collaboration of the authors over the past ten years has resulted in the acquisition and preservation of one of the most comprehensive ex situ woody plant seed collections represented in the U.S. National Plant Germplasm System and a Nationally Accredited Gymnocladus dioicus living collection at the Brenton Arboretum.  Systematical site selection and population sampling techniques strived to ensure a collection adaptable to a wide-range of climatic factors.  The firsthand knowledge of these genetic resources will help with species management efforts and demonstrate the importance of gene banks and arboreta in the conservation of tree genetics.
