The management of invasive weeds can be daunting task.  Invasive species are spreading across the landscape.  They ignore political and property boundaries, and when left unmanaged spread freely from neighbor to neighbor.  This unchecked movement, necessitates the need for strong partnerships and collaboration across political boundaries and across our region.  The WeedWise program is dedicated to partnering with local and regional entities to improve management of invasive weeds.  We work with various organizations on a regular basis to facilitate more effective control.  Below are just a few of the broad partnerships we support to improve management across our region.  Thanks to all of our partners for their support and dedication to reducing the impact from invasive weeds.

4-County Cooperative Weed Management Area (CWMA)

4cwma-CMYK_roundThe 4-County CWMA serves the greater Portland Metropolitan Area and includes Clackamas, Clark, Multnomah and Washington counties.  The partnership has twenty-eight formal partners representing federal, state and local governments,watershed councils, universities and local non-profits organizations.  The 4-County CWMA focuses on increasing collaboration  and communication among land managers within the Portland metropolitan area.  Issues related to urban weed management and public education are key areas of focus for the 4-County CWMA.

The WeedWise program has been a very active participant in the 4-County CWMA.  The WeedWise program currently administers the 4-County CWMA on behalf of the partnership.  All WeedWise program serves various leadership roles within the 4-County CWMA, including acting as CWMA Coordinator, Co-Chairing the CWMA Steering Committee, and Chairing the Mapping and Data Committee.

Clackamas River Invasive Species Partnership (CRISP)

CRISP(new colors)The Clackamas River Invasive Species Partnership (CRISP) is a relatively new partnership focused specifically on invasive species management within the Clackamas River Basin.   The CRISP has thirteen informal members organizations representing a diversity of interests across the Clackamas Basin.   This partnership has recently completed a strategic management plan for the Clackamas Basin, that prioritizes efforts within the Basin based on partner participation, the threat of invasive weeds, and the quality of land within the basin.  Work has begun to begin coordination of on-the-ground  control efforts among partners, and to secure additional funding for future invasive weed control efforts.

The WeedWise program has assisted CRISP partners by helping to draft the strategic plan, including development of site and species prioritization models.  Staff is currently helping to form sub-basin working groups, and to secure more funding to aid in future weed control efforts within the Clackamas Basin.

Columbia Gorge Cooperative Weed Management Area (CWMA)

Columbia Gorge logoThe Columbia Gorge Cooperative Weed Management Area (CWMA) is focused on collaborative weed management within the greater Columbia River Gorge.  The Sandy River Watershed in northern Clackamas County is one of the areas highlighted for management.  The Columbia Gorge CWMA has a strong focus on prevention and early detection of invasive weeds.  With an estimated 2 million people visiting the Columbia Gorge National Scenic Area each year, the CWMA focuses highly on education and outreach to the general public.  Public land managers are working collaboratively across the area, to prevent the establishment of invasive weeds, and to respond to new invasions as soon as they are detected.

The WeedWise program is an active member of the Columbia Gorge CWMA. The WeedWise program currently administers the Columbia Gorge CWMA on behalf of the partnership.  WeedWise program serve several leadership roles within the Columbia Gorge CWMA, including acting as CWMA Coordinator, and serving on the Steering Committee, and Education and Outreach Committees.

Oregon iMapInvasives

orimap-logo-fill-original-copyUnderstanding the distribution of invasive weeds is a critical component to effectively manage the dispersal and spread.  The mapping of invasive weed populations allow us to understand if weeds spread by roads or streams, what types of habitats they invade, and were we might expect new infestations to occur.  Oregon iMapInvasives has been a critical tool for the sharing and aggregation of invasive species distribution data.  Originally championed by the Oregon Invasive Species Council, Oregon iMapInvasives is overseen by the Oregon Biodiversity Information Center and is supported by fourteen partners working through the state of Oregon.  Continued development of iMapInvasives is also undertaken in cooperation from partners from eleven states or provinces.

The WeedWise program has been active partner of iMapInvasives since its introduction to the state.  The Clackamas SWCD, has been an financial supporter of the program since inception, and remains a strong advocate for its use.  WeedWise program staff have assisted the Oregon iMapInvasives in website testing, and enhancements to the database structure.

Oregon Invasive Species Council (OISC)

oiscThe Oregon Invasive Species Council is organization created in 2001 by the Oregon Legislature.  The council is comprised of a seventeen member panel representing diverse interests across the state.  The OISC considers impacts from all taxa including weeds, and they have championed many initiatives including the Oregon Invasive Species Hotline and Oregon iMapInvasives.  The council has a strong focus on education and policy within Oregon related to invasive species management.

The WeedWise program currently serves as the county lead for the Oregon Invasives Species Hotline, and actively promotes its use.  WeedWise program staff also serves on the council Advisory Committee to help inform decision making at the state level.

Pacific Northwest Invasive Plants Council (PNW-IPC)

PNW_IPC_LOGOThe Pacific Northwest Invasives Plants Council is a grassroots organization dedicated to preventing the spread of invasive weeds in the Pacific Northwest.  The PNW-IPC includes the states of Oregon, Washington, and Alaska and the provinces of British Columbia and Yukon.  The primary focus of this organization is to inform the policy makers and the general public regarding invasive species related issues, and to promote communication between managers at the state and national levels.

The WeedWise program has partnered with the PNW-IPC to host a citizen science based trainings in Clackamas County for early detection efforts in the Mt. Hood National Forest.  These efforts mirror similar efforts on other national forest in Washington.  The WeedWise program is pleased to support expansion into Oregon.

Play Clean Go

Play-clean-goPlay Clean Go is a national effort to prevent the spread of invasive species across the US.  This partnership focuses on messaging of the threat of invasive species, and potential for spread from recreation.  Originally developed in Minnesota, the Play Clean Go campaign has grown nationally to include more than 170 organizations working together to share a common message to prevent the spread of invasive species.

The WeedWise program formally joined the Play Clean Go campaign in 2015.  We are currently working with other local partners to share this common messaging throughout our region.
