Rapid Biotic Assessments 2014

If you know what bugs live in a river, you can gauge its health.

So, every year just as Summer slips into Fall, the Biocitizen Corps ventures out and catches some, following EPA protocols, in a national citizen science initiative called “Rapid Bioassessments of Benthic Invertebrates.”

Certain bugs need lots of oxygen. The cleanest coldest water contains the most oxygen—so a healthy river has lots of hyperventilating bugs in it. The kind brook trout love to eat.

The Biocitizen Corps deserves a lot of thanks and applause!

Our RBA 2014 crew included Jonathan Maginnis, Calvin and Emmett Spencer, Andrew Marotta, Silas James, Christopher Zima, Huxley and Dashiell Filas-Polson, Heather Polson, Sienna Wildfield, Persephone and James Sarantidis, Summer Sorenson, Lydia Donatelli, Tina Cornell, Heather Cups, Loiusa Kimball, Hannah Wilk, Sabrina Montenegro, Robin Huntley and her 5th grade class at Colrain Central School and Tara O’Brien and her Honor Science class at Hampshire Regional High School.

This year’s captures took us to these places:

Here are our data sheets for 2014.

We collected during a drought, so it’s possible that we saw less of certain species than usual: common stoneflies seemed to be less evident than in years past. In general, our rivers and brooks are healthy, though the bugs in Sodom Brook near Hampshire Regional High School keep getting smaller and its overall bug community less diverse. The Mill River in Northampton is holding steady. Our new RBA site on the North River in Colrain proved a pleasant surprise, as it contained many members of highly wanted hyperventilating bug families.

  • The River and the Machine: A Biocultural History of Holyoke Dam February 11, 2021
    WHAT IS BIOCITIZEN? The word “biocitizen” is a contraction of “biotic citizen,” a term and idea conceived by Aldo Leopold (1887–1948) who is widely celebrated for conceiving the “land ethic.” A thing is right when it tends to preserve the integrity, stability, and beauty of the biotic community. It is wrong when it tends otherwise. A […]

    Charlie is a recent graduate from Wesleyan University who is just beginning to get his footing in the big wide world and figure out where he’s going. Although he majored in music, his studies always seemed to circle around environmentalism and the more-than-human world, a cross pollination which began the summer after his freshman year […]
