At the midnight hour, it is Bioblitz time!

Starting at midnight Thursday October 20th through Sunday October 23rd, the Anacostia Watershed Society is sponsoring the 6th annual fall Bioblitz. This is an excellent opportunity to enjoy some fine fall weather and see what is out and about in nature this time of year.

All observations made in the Anacostia watershed will be included in the Bioblitz project. This is an activity that can be done at your own pace, or you can join one of the events planned for the weekend. Saturday will feature an entire series of guided tours and nature exploration activities at Kenilworth Aquatic Gardens from 10am to 3pm. Sunday from 1pm to 3pm will be an exploration of Guilford Woods.

Everyone is welcome to join in!

The 6th Anacostia River Bioblitz results are in:

-373 people engaged (both in person and virtual participation), the highest to date!
-2945 observations, also the highest number in 6 years!
-840 species, a little down from the last couple of years but this could be due to weather conditions affecting species activity since this has been the latest in the fall bioblitz so far.
-330 identifiers! this is also a record for our bioblitz so far! Huge thanks to all the iNaturalist community for helping identify our observations.
-Bird species: 58
-Amphibian species: 4
-Reptiles: 7
-Fish: 23
-Mollusks: 10
-Insects: 207
-Plants: 372
-Fungi: 95
-Protozoa: 1

Some records set in terms of the number of species observed:

-13 mammal species
-35 arachnid species

You can browse through the photos/data on the project page here: https://www.inaturalist.org/projects/6th-anacostia-river-bioblitz

Once again thank you very much for a very successful bioblitz in the Anacostia watershed!
