Life-long adult learners participate in hands-on workshops and classes on gardening, sustainable horticulture and botanical arts as well as field studies about birds and native plants. Kids and families enjoy discovery opportunities exploring plants and nature.

Kids get outdoors and have fun learning about the natural world through summer camp, scout programs and eco-birthday parties.

Tyler is recognized as an IBA (Important Bird Area) by the National Audubon Society and maintains an active Bluebird Nest box program with 47 monitored and maintained boxes.

Nine tree houses are open seasonally, generally from Mid-April through December.

Tyler’s 1,400-square-foot Butterfly House is filled with native butterflies, caterpillars, chrysalis and the plants they depend upon for survival. The House is open in July and August.
