2024-2025 Statement of Work Management of Undesirable Plants on USACE Lands The Dalles Project Klickitat County, Washington

DESCRIPTION OF SERVICES:

Recipient will assist the U.S. Army Corps of Engineers (USACE) with the management of undesirable plants on federal lands managed by the Natural Resource Management section at The Dalles Project (The Dalles Lock and Dam) in Klickitat County, Washington.

1. Coordination Assist in coordination through participation and leadership in Cooperative Weed Management Areas and other cross-boundary groups to manage undesirable plants from a strategic regional perspective. Manage and coordinate the actions of this Cooperative Agreement with relevant County Weed Boards, Soil and Water Conservation Districts and other political subdivisions of the state. Specifically, at the Project, recipient will share coordination, to the extent possible, in the Columbia Gorge Cooperative Weed Management Area.

1. Planning Assist in the development of a USACE-approved annual plan of work, identifying target species for inventory and management, prioritizing treatment based on regional plans, site location and level of infestation. Provide consultation to USACE on regional Best Management Practices including Early Detection and Rapid Response (EDRR) targets, quarantine initiatives, biological control releases, and updates to the State Noxious Weed List including new classifications, changes in classification of previously listed species, and delisting of species that have become a lower priority.

1. Surveying Assist with the inventory, survey, monitoring, and/or GIS mapping of exotic, noxious, invasive, or undesirable native vegetation at the Project. Maps, location descriptions, data and/or GIS information will be provided to the USACE Project Natural Resource Section that will aid in the management of areas. USACE may provide a USACE-operated vessel for survey activities. Data and vessel access require coordination with the Grants Officer’s Representative (GOR).

In the Columbia River region, targets for early detection include, but are not limited to:

a. Flowering rush (Butomus umbellatus) is among the region’s highest priorities for early detection because of its potential to devastate riparian habitat. It is so far absent from lands and waters managed by the Dalles Project.

3. Implementation Assist in the implementation of the appropriate integrated treatment method as prescribed or approved by USACE biologists, natural resource specialists, natural resource managers, and coordinated with the GOR. Implementation will be aligned with the Portland District Pesticide Discharge Management Plan (PDMP, Attachment 7). Treatments may employ prevention, mechanical, cultural, biocontrol or herbicide methods. Where practicable, biocontrol methods and other effective non-herbicide methods are preferred. USACE may provide a USACE-operated vessel for treatment activities. Vessel access requires coordination with the GOR.

Specific targets at the Project include:

a. Yellow star-thistle, rush skeleton weed along Bob’s Point road (2 acres)

b. Russian thistle at Avery Park (0.5 acres)

c. Perennial pepperweed at Avery Park (0.2 acres)

d. Knapweed, rush skeleton weed at Hess Park uplands (10 acres)- good candidate for biocontrol due to density and extent of infestation (ex. broad-nosed knapweed seed head weevil, rush skeleton bud gall mite)

e. Knapweed, rush skeleton weed at Spearfish Park uplands (10 acres) - good candidate for biocontrol due to density and extent of infestation (ex. broad-nosed knapweed seed head weevil, rush skeleton bud gall mite)

f. Blackberry at Spearfish Park (0.3 acres)

g. Flowering rush, should it be found along the shoreline of Lake Celilo in Klickitat County, Washington. EDRR is critical for this species. A cultural clearance must be performed by USACE before any substrate-disturbing activity.

h. Any other infestation identified by recipient and agreed upon by the Project Natural Resource Section, if within the scope of this agreement and funding is available.

4. Reporting If chemical methods are planned during the Period of Performance, an “Anticipated Pesticide Use” report will be submitted by the recipient to the GOR prior to implementation. An “Actual Pesticide Use” report will then be submitted by the recipient to the GOR by 15 December, outlining the actions completed each year. Templates will be provided by USACE to ensure the required data outlined in the PDMP (Attachment 7) and EPA pesticide regulations are included.

SCHEDULE:

An initial meeting between the recipient and USACE will occur within four (4) weeks of the execution of this Cooperative Agreement. A schedule will be coordinated at that time. Additional ad hoc work within the scope of this Cooperative Agreement may be requested throughout the Period of Performance as needs arise and if funding is available. Additional work will be implemented by a bilateral modification.
