Washington, DC

Join us for a family friendly bioblitz at the Capitol grounds led by DC author and naturalist, Melanie Choukas-Bradley.

Space is limited and registration is required.

Melanie will describe spring flowers, fruits and leaves and will teach attendees how to identify the diverse species of trees in the area including oak, maple, beech, and buckeye. Melanie will also share a little bit on the history of the Capitol Grounds and on the city of Washington, DC.

The tour will meet at the US Botanic Garden at 10:00 a.m. Restrooms will be available. The tour is expected to last up to three hours.

Attendees are encouraged to bring water, snacks, and/or a light bagged lunch. Please wear comfortable walking shoes and bring binoculars if you wish. Sunscreen and bug spray may be needed. The tour will be canceled in the event of rain.

Melanie Choukas-Bradley has authored a host of critically acclaimed books including, City of Trees: The Complete Field Guide to the Trees of Washington, DC, illustrated by Polly Alexander. 

The Capitol tree tour is one of five guided events that the MD/DC chapter is offering as part of the City Nature Challenge.
