Arboretum Releases New “Living Collections Policy” The U.S. National Arboretum is pleased to release a new “Living Collections Policy” which describes the purposes and procedures for decisions and practices related to living Germplasm at the Arboretum. As a conservator of plant materials for current and future research purposes, and for public display and education, we developed this policy to reflect guidance from the scientific and broader stakeholder community and to serve our mission to foster discovery leading to economically, environmentally and aesthetically valuable landscapes and environmental horticulture. The policy will be in force for five years, after which it will be subject to review and revision. Colien Hefferan, Director
