The Park District is participating in a Morton Arboretum study to treat and track the health of declining oak trees at Heller Nature Center and Sunset Woods Park. A total of eight District trees (four white oaks and four red oaks) are part of the ongoing study. According to the USDA Forest Service, management solutions are urgently needed to cope with the large number of oak trees that are declining in our nation’s forests. The Park District has been working to address oak decline since 2019 and has a tradition of strategically planting new trees in our parks.
