This edition (Spring 2011) of the Landscape Management Plan is the result of the continuing work of the Horticulture Department of the Arnold Arboretum. It is a detailed game plan that communicates the shared goals and priorities collectively developed by the horticulture team. The Plan’s goal is to maintain exemplary standards of horticultural care and management that provide optimal growing conditions for our collections, enhance the ecological health of the Arboretum environment, and present a landscape of outstanding quality for visitors, students, the surrounding community and other key constituencies.
