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.

We track the spread of invasive species and identify new infestations before they proliferate.
- Attend an in-person workshop
We host free Weed Watcher Workshops each spring to teach residents how to identify invasive plant species and to connect them to local community science efforts. You can also join our Tualatin Watershed Invasive Species Team Facebook Group!

We’ve recorded our Weed Watchers Workshop for participants to watch on their own. After you’ve watched the workshop, we encourage you to take a short quiz to test your ability to identity Tualatin SWCD’s priority weeds.
