Every fall the Botanic Garden assesses both the physical condition and the content of the arboretum collections. For this assessment, staff curators and arborists determine if any arboretum trees are at the end of their healthy life, or if species pose an ecological threat to native habitats. As part of this routine collection care, the Botanic Garden of Smith College, in conjunction with the Smith College Grounds Department, will begin the annual task of removing select trees from campus in January.
