Clackamas River Invasive Species Partnership

CRISP(new colors)

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:

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.

Many thanks to all of the CRISP partners, including:
