Spring Bioblitz with the City Nature Challenge April 29-May 1

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.

Right now we are gearing up for the City Nature Challenge, an international day of springtime species identification.  The City Nature Challenge runs from April 29-May 2.  Particpate at home or in any of these events hosted by the Anacostia Watershed Society and our partners:

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.
