Invasive weeds currently cost Oregonians millions of dollars each year. One recent estimate indicates that without intervention these will increase to $1.8 billion in personal income losses a year from degraded lands and reduced productivity. What is being done? A local effort is underway to help mitigate the impacts of these invasive weeds along the […]

The Clackamas River Basin is not without its fair share of invasive weeds. Thankfully, we have a hard working group of skilled land managers actively managing these invasive weeds. Formed in late 2015, the Clackamas River Invasive Species Partnership (CRISP) was established to improve the coordination of weed management in the Clackamas Basin. This partnership […]
Working Together to Control Weeds
The Clackamas River Invasive Species Partnership (CRISP) was formed to improve the management of invasive species within the Clackamas River watershed in northwestern Oregon. This partnership was initiated through the cooperative efforts of the Clackamas River Basin Council (CRBC) and the Clackamas Soil and Water Conservation District (CSWCD), with additional funding and support from Metro regional government.
Prior to the group’s formation, the Clackamas River Basin Council and the Clackamas Soil and Water Conservation District both had strong landowner assistance programs for control of priority invasive weeds and to restore riparian habitat in targeted areas of the watershed. Development of the CRISP has provided an opportunity to coordinate the efforts of these two organizations, as well as other partners across the Clackamas River watershed.
Developing a Plan
The first goal of the partnership was to identify current invasive species control efforts underway within the watershed. Tools such as online surveys and stakeholder meetings provided this information. Second, a Technical Advisory Group (TAG) of federal, state, regional, and local land managers convened to discuss existing efforts, long-term goals and outcomes, available resources, and management strategies. Information provided by the TAG served as the foundation for development of the Clackamas River Invasive Species Management Plan, a comprehensive approach for managing invasive species within the watershed. The TAG meetings revealed strong support for invasive species planning among participants. During these meetings, TAG members broadly agreed to participate in ongoing planning and implementation efforts. The partnership grew to include the 22 TAG members from 13 organizations.
In addition to the information provided by the TAG, a prioritization model known as the Weed Heuristics: Invasive Population Prioritization for Eradication Tool (WHIPPET), developed in California, was adapted for use within the Clackamas River watershed. The WHIPPET model helped prioritize infestations of 19 priority invasive species based on their potential impact, potential spread, and feasibility of control. Criteria related to specific populations, the ecology of the invasive species, and the quality of the area under threat, were all included in the WHIPPET model analysis.
Due to the size and complexity of the watershed, as well as resource scarcity, CRISP partners also sought to prioritize specific geographic areas for action. They ranked sub-watersheds based on:
- data from the Intertwine Alliance’s Regional Conservation Strategy;
- existing partner participation; and
- rare, threatened and endangered species.
The findings of this assessment were considered alongside additional factors including partner investments and engagement resulted in the establishment of four priority areas within the Clackamas River watershed.
Action plans created for each of the four priority areas were based on land use, the likelihood of invasive species introduction, survey and control needs, and restoration opportunities. These priority area action plans collectively form the Clackamas River Invasive Species Management Plan, which was completed in 2015. This plan outlines a clear and objective approach to managing invasive species in the Clackamas River watershed.
Funding the Plan
In order to implement the management plan, the CRISP sought funding to treat invasive weeds within the Clackamas River Basin. In 2016, the CRISP secured $431,250 in grant funding through the Clackamas River Hydroelectric Project Mitigation and Enhancement Fund to support implementation over the next five years. To support this grant, several CRISP partners also committed resources to the project. Commitments included $300,000 in cash and in-kind services from the Clackamas SWCD, $292,500 of in-kind services from Clackamas River Basin Council, and $145,000 in cash and in-kind services from Metro. Additionally, the BLM awarded a partner agreement to Clackamas SWCD totaling $8,500 to CRISP in 2016, which is renewable pending available funding. This agreement is part of a larger funding pool that also includes weed control efforts in Sandy River Basin as well as administration of the Columbia Gorge CWMA and 4-County CWMAs.
Where are we now?
Although the grant resources were unavailable until late in the 2016 field season, CRISP partners reported expending $448,850 in contracted weed control and restoration services in 2016. The total estimated CRISP-related activities reported by partners in 2016 totaled $737,608. This work supported weed management and related activities on 2,836 acres of public and private land. See the full 2016 CRISP Annual Report here. The 2017 Annual Report is now in progress and will be available soon.
In 2016, the CRISP grew from its origin as an advisory group supporting the CRISP Management Plan development effort to a partnership. This transformation required the development of basic infrastructure to support the goals and activities of the partnership. The Memorandum of Understanding (MOU) outlines the partnerships goals and structure and has now been signed by all partners. See the full CRISP MOU here.
To further enhance implementation efforts in the basin the Clackamas SWCD also hired a specialist to assist with implementation of CRISP-related activities. This CRISP specialist supports activities between partners and in identified gaps in management. The position was filled in
mid-December 2016 and will support the partnership moving forward into the five-year grant-funded implementation cycle.
Planning of cooperative implementation activities is currently underway for the 2018 field season.

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.

Understanding 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.

MANY THANKS TO ALL OF OUR PARTNERS!
The WeedWise Program is dedicated to helping protect Clackamas County from the ongoing threat of invasive weeds. These projects are often based around the prevention or management or priority invasive weeds. We currently working on projects across the county, but focus largely on priority invasive weeds, priority sites, or on partnership projects.
Priority Weed Control Projects
The priority weed control program focuses on the Early Detection and Rapid Response (EDRR) of new or rare invasive weeds where the goal is either eradication or containment. These projects allow us to focus our resources for maximum impact. Priority weed control projects typically occur at the landscape level and impact multiple landowners either public or private. These project focus on the control and eradication of a priority weed species. Some examples of our current priority weed control projects include the active management of:
- Garlic mustard (Alliaria petiolata)
- False brome (Brachypodium sylvaticum)
- Spurge laurel (Daphne laureola)
- Oblong spurge (Euphorbia oblongata)
- Japanese, Giant, and Bohemian knotweed (Fallopia japonica, F. sachalinensis, and F. x bohemica)
- Goatsrue (Galega officinalis)
- Orange hawkweed (Hieracium aurantiacum)
- Giant hogweed (Heracleum mantegazzianum)
- Policeman’s helmet (Impatiens glandulifera)
- Blessed Milk Thistle (Silybum marianum)
- Puncturevine (Tribulus terrestris)
- Gorse (Ulex europaeus)
The priority weed control projects are one of our highest priorities and target all known infestations across the county or within a given management area.
Priority Site Projects
Priority site projects are projects that are designed to protect areas of exceptional quality or of unique ecological, economic, or cultural importance. Some examples of projects that the WeedWise program is currently working on or have spearheaded in the past include:
- Barton Area Priority weeds project
- Bull Run Gate weed control project
- Coral Creek weed control project
- Molalla River confluence project
- Newell Creek restoration project
- Salmon River priority weed control project
- South Creek-Abernethy project
- Lolo Pass priority weed control project
The priority site project areas are typically local or regional significance and are designed to protect or buffer these areas from the encroachment or spread of invasive weeds. The goals of these projects is typically focused on exclusion and maintenance of natural areas within the project areas.
Partnership project are those projects that are typically undertaken in conjunction with local and regional partners. These projects are often complex and have diverse interests. These projects involve working in cooperation with partner organizations to implement projects across broad geographic areas or across jurisdictional boundaries. Examples of partnership projects include:
- The Backyard Habitat Certification Program Clackamas County Expansion
- The Clackamas River Invasive Species Partnership Upper Clackamas Surveys
- The Clackamas River Invasive Species Partnership Focus Area weed control project
- The Portland Metro Garlic mustard working group
- The Mt Hood National Forest Working Group
- The Sandy Basin Vegetation Restoration Coalition priority weed control
