2026 Bioblitz – September 10th-13th, 2026

The Anacostia River watershed is home to an incredible number of species, and it takes a village to get out there and document them. A bioblitz is a communal effort to record as many species as possible within a designated location and time period. Our bioblitz uses the free iNaturalist (www.inaturalist.org) application to record the data. However, the goal of our bioblitz is to educate the public about the watershed’s natural heritage and the use of the application is optional during our public events. The very first bioblitz ever was held right here in the Anacostia River watershed at Kenilworth Aquatic Gardens in 1996! Our own Anacostia River Bioblitz has been held annually since 2017. 

Bioblitz events are opportunities to explore the natural treasures of the Anacostia River, but more importantly, it will be your opportunity to engage in community science to help us document the biodiversity of the Anacostia River watershed. The Bioblitz and the City Nature Challenge are weekend-long events where you can make your own observations using the iNaturalist app, at your own pace, from anywhere within the watershed. This is a great opportunity to learn about the identification and ecology of some of the river’s fascinating species.
