The Cylburn Arboretum Association (CAA) is a 501(c)(3) nonprofit organization dedicated to protecting Cylburn Arboretum as a place of open space, beauty, and learning.  For over half a century, CAA has partnered with Baltimore City to co-sponsor hundreds of programs and events. These activities have brought thousands of City residents and visitors to Cylburn and provided opportunities to better understand and appreciate the natural world. Approximately 150 volunteers help maintain gardens and trails, staff programs and special events, and oversee the Cylburn Nature Museum, home to an extensive collection of birds and other wildlife.  CAA provides annual financial support to the environmental education program offered at Cylburn which allows more than 2,000 school age children from Baltimore City schools to have access to Cylburn Arboretum.  In addition, younger children ages 3-6 participate monthly in Nature Story Hour and learn about the natural world around them.   CAA sponsors events such as Market Day, a premiere plant-sale fundraiser that draws thousands of residents each May and holds cultural events such as the Chamber Music Series in the Cylburn Mansion.   The Association has its offices on the second floor of the Cylburn Mansion.
