Aquatic Invasive Species Monitoring

VTDEC staff routinely sample Vermont waters to:

  • Check for and document infestations of nuisance species in new waterbodies
  • Evaluate population status of existing infestations
  • Determine what if any control efforts can be used on existing infestations
  • Assess habitat suitability of waters to determine risk of a possible invasive infestation

You can help monitor Vermont waters for invasive species: Become a Vermont Invasive Patroller.

Zebra mussel monitoring

Spiny Waterflea Monitoring

Due to the discovery of Spiny Waterflea in Lake Champlain in 2014, VTDEC staff routinely monitor other lakes for new infestations of the invasive zooplankton. As of 2015, no new infestations have been discovered.

Aquatic Macrophyte Monitoring

The Aquatic Macrophyte Monitoring Program collects baseline information on aquatic plant communities in Vermont lakes by conducting descriptive surveys using a pre-established plant cover scale.  These efforts also track rare, threatened and endangered aquatic plants; information that is shared with the Department of Fish and Wildlife's Heritage Program. This monitoring program has been active since the late 1970s, and discrete survey information is available.
