Volunteers Track Invasive 'Rock Snot' In N.H. Rivers

Jun 11, 2012

Volunteers across the state will begin monitoring rivers for the invasive species, Didymo. 


The New Hampshire Rivers Council is launching a new program to train volunteers to report early signs of the cold-water-loving single-celled algae, known as rock snot.

The council’s Michele Tremblay says Didymo is now moving into the state’s rivers and streams.

“I always like to say the invasive species they’re not just for lakes any more, they’re in our rivers.  And Didymo is a particular concern because it will choke out any life ... it just does horrible things to the habitat.”

The New Hampshire Rivers Council will be providing workshops for local conservation commissions and other grassroots groups.

“We realized that it made a lot of sense to train them to learn to recognize didymo and other invasive species, and that way we’d have early detection of any potential infestations and we’d be able to react quickly and eradicate it and stop the invasion.”

Workshops will take place all across the state.
