Hi all!

The 7th Anacostia River Bioblitz has already a record number of observations (3064 observations!) since we started the #AnacostiaBioblitz in 2017. The same is true for the number of species = 934 species observed during the weekend! Also record numbers of species observed in the Arachnid department with 36 species observed, and 297 insect species observed!
