Tyler Arboretum

Support our Ecosystems as your Community!

How did you first discover Tyler Arboretum? Was it a school field trip? A bird walk, or a hike with the Scouts? Maybe your parents or grandparents brought you here to count turtles in the pond and explore the treehouses? 

For 81 years, Tyler Arboretum has been a green oasis, a natural sanctuary in the heart of Delco. As the County has grown around us, we remain committed not just to stewarding 650 acres of greenspace, but to sharing it with our community, connecting children and adults to nature and nurturing their appreciation of the natural world. 

The arboretum is home to gardens, world-renowned horticultural collections, magnificent trees, and miles of hiking trails. Our 650 acres support complex ecosystems made up of a great variety of plants and animals, both seen and unseen. One of our primary goals at Tyler is to protect these diverse and beneficial ecosystems.

Did you know:

• 
  Only two Delaware County streams are classified as "unimpaired" by the Pennsylvania Department of Environmental Protection— both flow through Tyler Arboretum. Thanks to careful conservation, Rocky Run and Dismal Run remain pollution-free. These pristine waterways provide clean water, rich habitats, and a refuge for countless species.


• Our commitment to conservation has earned us the distinction of an Important Bird Area from the National Audubon Society — placing us among 2,758 vital bird habitats nationwide.

Through the changing seasons, we welcome hikers, gardeners, nature-lovers and the nature-curious of all ages to breathe deep and recharge. For upcoming tours, events, educational offerings, volunteer opportunities, and to learn about membership, visit our website at tylerarboretum.org
