The Cox Arboretum Foundation was created over 50 years ago by a small group of community activists who were passionate about preserving the Dayton area's undeveloped land. Once a barren farm, the Arboretum's 189 acres now gleam as one of the region's most beautiful natural jewels, welcoming more than 650,000 visitors per year.
Since its inception in 1963, The James M. Cox, Jr. Arboretum Foundation has strived to provide an “living museum” for the Dayton community where people of all ages can come to learn about and engage with nature. The Foundation provides financial support to Cox Arboretum MetroPark in a unique public-private partnership with Five Rivers MetroParks.
A movement to "save open spaces" in the Dayton area gains momentum and catches the attention of Jean Mahoney, Jean Woodhull and others who are eager to take up the cause.
Jean Mahoney presents a plan to James M. Cox, Jr. to establish an arboretum on the site of his 169-acre farm.
