1. PURPOSE, DESCRIPTION OF SERVICES, AND REQUIRED

TASKS

1.1. PURPOSE

The purpose of the sheep grazing services is to manage vegetation through prescribed grazing at Travis Air Force Base (TAFB). The Contractor will graze sheep to reduce hazardous fuel loads for wildfire mitigation and to suppress the growth of invasive plant species. These services will decrease overall wildfire risk to protect public health and safety, and control non-native growth across the installation.

1.2. DESCRIPTION OF SERVICES

The Contractor shall perform Sheep Grazing Services to reduce fuel loads and suppress the growth of invasive plant species. While sheep shall serve as the primary grazing method, co-grazing arrangements utilizing cattle may be permitted at the sole discretion and approval of the TAFB Natural Resource Manager (NRM) and Contracting Officer’s Representative (COR). To accomplish this, the contractor will coordinate with TAFB NRM and COR to determine the location, intensity, and approved livestock composition for grazing.

Currently, TAFB has eleven (11) grazing pastures which are suitable for grazing operations (Figure 1). Grazing will comply with the 2024 TAFB Grazing Management Plan, which outlines Animal Unit Month (AUM) and land use regulations for each pasture (Table 1). The Contractor will be responsible for monitoring grazing at each location and coordination with NRM/COR when livestock should be rotated. Contractor shall provide an on-site shepherd which will manage the herd 24 hours a day for 7 days a week basis. The Contractor shall provide an RV/trailer for the shepherd's living accommodations, which can be parked in pre-determined locations closest to the pasture where the animals are located.

The Contractor is responsible for complete mobilization and demobilization of animals, staff, and all equipment on and off the installation. Foreign nationals may be approved as shepherds, however, will be subject to background checks and necessary access procedures. The COR/NRM will submit any application for base access. The Contractor shall have and maintain all licenses and certificates required to perform all work requirements in this Performance Work Statement (PWS). The Contractor shall, provide everything needed to perform grazing at TAFB, as defined in the PWS except as specified in the PWS as Government furnished property or services. The contractor will be held liable for any damages to government property as a result of work activities including but not limited to the items covered in Section 2 below. All work performed by the Contractor in the PWS shall conform to the applicable latest editions of the following specifications and standards but not limited to:

- Travis AFB Engineering Specifications section 01 56 00 Environmental General requirements.

- Travis AFB Grazing Management Plan Version 2, 2024.

- Travis AFB Integrated Natural Resource Management Plan.

- Travis AFB Invasive Species Management Plan.

1.3. DESCRIPTION OF REQUIRED TASKS

The Contractor shall perform the following core tasks to fulfill the grazing requirements at Travis

AFB:

1.3.1. Mobilization, Demobilization, and Access

The Contractor shall transport all animals, personnel, RVs/trailers, and required equipment to and from the installation. Prior to mobilization, the Contractor shall provide all necessary information to the COR/NRM to facilitate base access applications and background checks for all personnel, including foreign national shepherds. The contractor shall coordinate with COR for locations of RV/Trailer staging. The contractor shall also provide applicable medical certificates for the livestock clearing them to graze on the installation.

1.3.2. Prescribed Grazing and Rotation Management

The Contractor shall execute grazing within the designated pastures in strict compliance with the land use regulations in the 2024 TAFB Grazing Management Plan and other applicable environmental specifications. Sheep shall be utilized as the primary grazing method; however, co-grazing utilizing cattle may be integrated only upon prior coordination and written approval from the

COR.

The Contractor shall actively monitor forage conditions and coordinate directly with the COR to determine grazing intensity, livestock composition, and execute timely herd rotations. In general, the Residual Dry Matter (RDM) range shall be maintained between 500–2,000 lbs./acre for each pasture, unless otherwise directed by the COR to meet specific fuel load or ecological targets.

The contractor shall provide an on-site shepherd to actively manage, contain and care for the herd on a 24/7 basis. The contractor shall park the shepherd’s RV/trailer only in pre-determined, Government approved locations nearest the active grazing pasture. The contractor shall provide all necessary resources, water, and care to sustain the herd independently, ensuring operations do not cause damage to government property.

1.3.3. Project Management

The Contractor shall provide comprehensive project management and administrative oversight to ensure the successful execution of this contract.

The place of performance shall be Travis AFB, California. Grazing operations shall be strictly confined to the eleven (11) designated pastures, totaling approximately 520 acres, as mapped and defined in the 2024 TAFB Grazing Management Plan (Figure 1). However, the Government is not obligated to utilize all eleven pastures each year; the specific pastures, acreage, and location of active grazing will be determined annually or seasonally based on forage conditions and base operational needs. Less acreage may be made available for grazing at the sole discretion of the

COR/NRM.

All livestock offloading, equipment storage, and staging activities shall occur only within specific areas pre-approved in writing by the COR. The contractor, equipment, and livestock are strictly prohibited from entering any other base location outside the designated grazing footprint and approved transit routes.
