Invading the Connecticut River: The Spread of Hydrilla
CAES IAPP is featured in a mini documentary on hydrilla in the Connecticut River.

November 2019

On Friday, November 29, 2019, CAES IAPP placed three HOBO data loggers in Lake Beseck, Middlefield with the Lake Beseck Environment Committee and Aquatic Ecosystem Research. These data loggers will track air temperature, sediment temperature, and sediment moisture during the winter drawdown of the lake.

Summer 2018
CAES IAPP and other organizations conduct a preliminary survey of the invasive species Hydrilla verticillata (Hydrilla) in the Connecticut River.

Azolla in Westport, CTAzolla in Suffield, CT
Azolla sp. (water fern) covering private ponds in Westport (left) and Suffield (right), CT.
CAES IAPP surveyors Jordan Gibbons and Jennifer Fanzutti found  Azolla sp. (water fern) covering ponds in Westport and Suffield, CT.  We think the warm winter prevented the normal dieback of this southern plant and will monitor if it continues to spread next year. If it does, Azolla sp. could become an extremely destructive invasive aquatic plant statewide. We brought plant samples back to the laboratory and planted them in our greenhouse tanks for futher analysis.

March 2011
The extensive aquatic plant herbarium is brought online. View the Online Herbarium.



CAES IAPP begins resurveying lakes originally surveyed 5 or more years ago to determine changes. In some cases, the increase in invasive aquatic species is dramatic. Below is a comparison of the vegetation in Cedar Lake, Chester. Note the increased acreage of Cabomba caroliniana (dark green) from 2004 to 2010.




Scientists at the Connecticut Agricultural Experiment Station begin surveying Connecticut lakes and ponds for invasive aquatic plants and investigating novel management options.
