2024-2025 Statement of Work Management of Undesirable Plants on USACE Lands John Day – Willow Creek Project Klickitat County, Washington

DESCRIPTION OF SERVICES:

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

1. Coordination Assist in coordination 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.

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 because of its potential to devastate riparian habitat. Its presence is minimal on lands and waters managed by the John Day Project, but vigilant surveying is required to detect and prevent further spread.

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. John Day Dam North Shore Operations Areas (18 acres maximum)

i. Spot treat dry land areas and road shoulders for knapweed, rush skeleton weed and Dalmatian toadflax.

b. Cliffs Park (18 acres maximum)

i. Spot treat dry land areas and road shoulders for state-listed weeds.

c. Railroad Island Park (12 acres maximum)

i. Spot treat dry land areas and road shoulders for knapweed, rush skeletonweed and Dalmatian toadflax.

d. Rock Creek Wildlife Management Area (6 acres maximum)

i. Total vegetation control of paved roadways and parking areas. Establish a three-foot control area along perimeter of both sides of the road.

e. Sundale Park (2.5 acres maximum)

i. Total vegetation control of paved roadways and parking areas. Establish a three-foot control area along perimeter of both sides of the road.

ii. Treat vegetated area for whitetop hoary cress, puncturevine and other invasive species.

f. Roosevelt Park (11 acres maximum)

i. Total vegetation control of paved roadways and parking areas. Establish a three-foot control area along perimeter of both sides of the road from the entrance sign to the boat launch.

ii. Spot treat swim beach and road shoulders for False Indigo (Baptisia australis) and other state-listed weeds.

g. Alder Creek (7 acres maximum)

i. Foliar spot treatment of False Indigo (Baptisia australis) and other state-listed weeds in mitigation site.

h. Lake Umatilla Shoreline

i. EDRR for any presence of Flowering rush. A cultural clearance must be performed by USACE before any substrate-disturbing activity.

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 6) 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.
