The Collections Committee (originally known as the Plant Materials Committee) was formed in 2010 to review proposed materials and locations of horticultural collections within the Arboretum, including research collections. The most important function of the committee is to develop and review curatorial policies and to set priorities for the long-term development of the Arboretum’s plant collections.
