Think you found a new invader? Please report to the Oregon Invasives Hotline to help prevent it from become a bigger problem

Welcome to the Western Invasives Network

Want to attend a weed watcher training in Oregon? Click to find out about the Next training.

The GOAL of WIN is to provide information and tools to help develop and strengthen a network of public and private partners and citizen volunteers that work in cooperation to detect and control invasive species before they become a problem.

On this site you can find:

  • Basic guidelines on Early Detection and Rapid Response as a strategy for addressing invasive species.
  • Opportunities to stay engaged in a network of public agencies, non profits, and concerned landowners working together to fight invasive species.
  • Volunteer Weed Watcher information! Check out the Weed Watchers Program to learn about a weed watcher program near you and how to get involved.
  • Species to report from your area, and information about identification and control. Please click on our interactive map to learn more.
  • Interactive news and events where you can keep up to date on EDRR successes in your areas and how other people are staying involved. Please contact us if you would like your activity or event posted on the WIN website
  • Tools for starting your own invasive species early detection network. See the Weed Watchers Program page.

Why Should We Worry About Invasive Species?

Invasive species have a negative impact on both the ecology and economy of our region. Weedy species reduce the economic viability of farms and ranches, and cost countless dollars a year to control and eradicate. The rapid reproduction and aggressive nature of invasive species displaces native plants, and permanently alters our natural environment. Invasive species are recognized as one of the most severe threats to biological diversity, second only to direct habitat loss and fragmentation. As a form of biological pollution, invasive species spread well beyond their point of introduction ultimately altering large expanses, if left unchecked. Read more about invasive plants.

Why Early Detection and Rapid Response?

After prevention, Early Detection and Rapid Response is the most cost effective and efficient method of dealing with invasive species. If emergent populations of problem invaders can be identified quickly after introduction treatment is much more efficient. This method relies on educating people to identify and communicate problem weeds before they can gain a foothold. This approach requires a shift in resources toward education, monitoring, communication, and developing a planned response.

The Western Invasives Network aims to prevent the spread of weeds by serving as a one stop shop for information on invasive species prevention, detection, and management. This site provides information dedicated to the best management practices, news, current events, grant opportunities, and various resource links to identify and combat invasive species.
