The Clackamas/Clark/Multnomah/Washington County Cooperative Weed Management Area (4-County CWMA) is a partnership of organizations, agencies and non-profits dedicated to combating invasive weeds across the region. Member organizations have committed to these efforts for a variety of reasons: supporting agricultural production, protecting human health, and preserving air, water and soil quality.
Those reasons are often locally based: cities and farms worry about and deal with invasive species differently. In a related way, the range of habitats in the Lower Willamette Valley plays a role in dictating which species are invading, and how problematic they are. So, the diversity of the landscape is a crucial consideration around here, leading to a wide range of management activities and strategies.
And, of course, invasive species don’t care about boundaries. So collaboration across jurisdiction has become a critical response. In addition to keeping treatments consistent across boundaries, partnerships can sometimes give rise to new sources of funding, and make for more efficient projects.
All of this informs our website. We talk to a lot of different people in a lot of different situations. We’ve designed our website to reflect that range.
We hope. If you think otherwise, or can’t find what you’re looking for, please let us know. We’re aiming for ‘perfect’ but haven’t quite gotten there, yet…
