Invasive species threaten our ecosystem.

They outcompete native plants and animals, reducing biodiversityBiodiversity The variety of species present. and altering our watershed’s habitats.

They can also have devastating economic impacts and harm human well-being. Invasive species often lack natural predators that keep them in check. This allows them to grow unrestrained, causing tremendous damage to productive land, decreasing water quality, and destroying wildlife habitat.

Prevention:

We identify, survey, and treat invasive plant and animals that pose a threat to our landscapes and communities.

We collaborate with partners and residents to prevent the spread of invasive species, detect new infestations, and increase public awareness about Early Detection and Rapid Response (EDRR) species within our watershed.
