2020 PERENNIAL REPORT

From the President and CEO
For The Morton Arboretum, 2020 brought disruptions and challenges like none in its history. While the coronavirus pandemic required adaptations to norms and plans, the Arboretum stood resilient and advanced its mission to plant and protect trees for a greener, healthier, and more beautiful world. Important tree research and conservation initiatives continued, events and programs were redesigned for safety or moved online, and the Arboretum provided access to the restorative power of trees for all who visited. 

Like many organizations, The Morton Arboretum experienced significant financial losses due to the year's hardships. Generous support through annual memberships, philanthropic contributions, and business and community partnerships were essential in reducing the deficit. The dedicated efforts of staff, volunteers, and partners made possible the Arboretum’s continued impact as The Champion of Trees.

The Arboretum’s response to the dire circumstances that emerged in 2020 demonstrated its enduring strength. Like a great tree with deep roots, with the support of donors and members, The Morton Arboretum is resilient, adaptable, and full of promise for the future. Thank you for valuing trees and supporting The Morton Arboretum in 2020 and beyond.
 
With appreciation,
