Anacostia River Bioblitz

Community-driven Record of Our Region's Biodiversity
Anacostia River Bioblitz
Community-driven Record of Our Region's Biodiversity
2022 Bioblitz - October 20-23

The Anacostia Watershed is home to an incredible amount of species, and it takes a village to get out there and document them all. A bioblitz is a "Census of the Natural World" where over a short period of time, communities go out and document the species they see. The very first bioblitz was even held right here in the Anacostia Watershed at Kenilworth Aquatic Gardens. This year in 2022 we celebrate the 6th Anniversary of our spearheading of the Anacostia River Bioblitz.

To record your results or follow along at home at iNaturalist, please use this project: 6th Annual Anacostia River Bioblitz.

This year, we have a whole slate of events that you can join:

  • Community Science: The Anacostia Bioblitz and iNaturalist on Zoom
    Monday, October 17, 7-8pm
    Join us for this virtual even with Ana Ka’ahanui, co-founder of Capital Nature; Serenella Linares, Audubon Naturalist Society; and Deborah Barber, The Nature Conservancy, to learn all about the Bioblitz.

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

Our main tool is the crowd-sourced (and free!) iNaturalist app ( Watch the videoat the bottom of this page to learn more about how to use iNaturalist!

When you're out there exploring, here are some things to remember to bring:

          • We will be using the iNaturalist app for our documentation and identification. Create an iNaturalist account (click here to sign up), and download the app to your smartphone before you get there.
          • Bring a dry bag or any other waterproofing device to protect your phone in case of rain.
          • Reusable water bottle filled with water
          • Sunscreen
          • Hat and sunglasses
          • Insect repellent
          • Sealable bag, or dry bag if you have one, for your other personal items
          • Closed-toed shoes that can get damp
          • A notebook and pencil to record any other interesting information by the experts.
          • Camera if you are into photography and would like to take higher quality pictures to download later on iNaturalist from your laptop computer.
