PERFORMANCE WORK STATEMENT (PWS)

Vegetation and infrastructure rehabilitation for the Border 2 Fire San Diego National Wildlife Refuge, Jamul California

Part 1

General Information

GENERAL: This is a non-personal services contract to provide multiple services related to the rehabilitation of the Lower Otay Lake units of the San Diego National Wildlife Refuge (SDNWR), Jamul, California 91935 after damage from the Border 2 fire. Actions to implement shall include: 1) Invasive weed treatments within a buffer area of the northern boundary of the lower Otay Lakes unit, established dozer lines, and habitat rehabilitation mitigation areas; 2) Repair exclusionary fencing and install signage to prevent unauthorized access; 3) Native seeding and erosion control within habitat mitigation rehabilitation areas. The service provided by the Contractor will be to:

1) Treat invasive weed species that invade the burn area and that are adjacent to the burn, to prevent the area from converting from native habitat to an invasive weed species dominated area.

2) Repair exclusionary fencing in predetermined areas with signage installation along the border 2 fire footprint, dozer line intersections, habitat rehabilitation mitigation areas, and 1418 maintenance access road.

3) Replant native vegetation by way of hydroseed and hand seeding and implement erosion control within habitat rehabilitation mitigation areas.

The Government shall not exercise any supervision or control over the contract service providers performing the services herein. Such contract service providers shall be accountable solely to the Contractor who, in turn is responsible to the Government.

1.1 Description of Services/Introduction: The contractor shall provide all personnel, equipment, supplies, facilities, transportation, tools, materials, supervision, and other items and non-personal services necessary to perform invasive weed treatments within and adjacent to the burned area, fencing repair and replacement, and seeding activities as defined in this Performance Work Statement except for those items specified as government furnished property and services. All water needed to facilitate any action as described will be sourced and provided by the contractor. The contractor shall meet the standards in this contract.

1.2 Background: The Sage Fire started on January 23, 2025 on BLM property within the Otay Mountain Wilderness on Otay Mountain in San Diego, CA. Due to excessive red flag conditions, including a concurrent Santa Ana wind event, the fire continued to spread north and northwest through contiguous coastal sage scrub and Chamise Chaparral habitat. Adjacent to the BLM parcel where initiation happened, the fire spread and burned 346-acres of a parcel of the San Diego National Wildlife Refuge, referred to as the lower Otay Lakes unit. Within the burn area, a previously rehabilitated habitat mitigation area was burned, rendering the rehabilitation ineffective and in need of replacement. As a means of emergency fire suppression, CAL-FIRE destroyed fencing in specific areas to use industry standard dozers to create artificial firebreaks to prevent further spread of the fire.

The entire fire and suppression efforts occurred within coastal sage and chaparral habitats that support multiple endangered and threatened species, which included designated critical habitat for the Federally Endangered Quino checkerspot (Euphydryas editha quino) and Federally Threatened coastal California gnatcatcher (Polioptila californica californica). The California gnatcatcher, Quino checkerspot butterfly and it’s host plant dot seed plantain (Plantago erecta) was also recorded in the area during surveys in 2022 for an unrelated project. No direct mortality or injury to any threatened or endangered species was observed in the fire area. A small team of USFWS Refuge, Ecological Services, and Fire Management staff reviewed the fire and suppression activity impacts and conducted a post-fire assessment of values at risk, and recommended actions to protect or restore those values, including reducing risk of invasive plant spread in burned areas and recovery of native vegetation and wildlife habitats.

1.3 Objectives:

https://en.wikipedia.org/wiki/Quino_Checkerspot

1. Locate and treat weed species within a buffer of the SDNWR’s northern parcel boundary of the lower Otay Lakes unit which includes a subset of the burned area occurring on SDNWR and adjacent properties. Additional treatment areas include areas within dozer lines on SDNWR and all habitat mitigation areas (See figures 1, 4, & 5). The contractor shall implement a minimum of 2 visits to maximize eradication. All measures will be taken to avoid recovering native plants.

Treat weeds using a variety of equipment and methods as appropriate for maximum control.

Achieve target weed reduction goals outlined below with the objective of allowing native species to recover from burn effects and minimize the negative impact of non-native weeds on that recovery.

2. Locate and repair exclusionary fencing along the lower Otay Lakes unit boundary, northeast boundary lines, termini for all habitat rehabilitation mitigation areas, and the 1418 maintenance access road to reduce unauthorized use of the refuge and adjacent land management parcels (See Figures 2-5). Signage will be installed at regular intervals to provide effective notice of boundary access regulations.

3. Perform vegetation rehabilitation by seeding with native plants to restore a native dominated vegetation community within previously rehabilitated habitat mitigation areas (See Figure 4-5).

Additionally, implement erosion control measures in previously mitigated areas to reduce downslope sedimentation.

1.4 Scope: The contractor shall provide all personnel, equipment and supplies to:

1. Spot treat infestation of invasive weeds in and adjacent to the burn area. The contractor shall accomplish eradication of weed species crimson fountain grass, Bermuda buttercup, stinknet, fennel, stinkwort, black mustard, castor bean, Russian thistle, and any novel invasive weeds that may invade the area during the period of performance; no more than 1% cover of a 500-foot buffer from the northern boundary of the SDNWR parcel, all dozer lines on SDNWR, and habitat mitigation areas will support these species. To the extent possible, other non-native invasive species (e.g., redstem fillaree (Erodium cicutarium), wild oat (Avena barbata)) will be treated to reduce their cover to no more than 20% within the same areas. This percentage of cover is higher due to the high prevalence of these and other non-native grass and forb species in the area. The contractor shall provide the services for two fall/winter growth periods. Adjacent lands to the northern boundary of the burn area are managed by partner land management agencies/entities and invasive species mitigation work will be performed according to the specifications above with appropriate access permission. All dozer lines to be treated are completely within the SDNWR boundary.

2. Locate and repair exclusionary fencing along the lower otay lakes unit of the SDNWR boundary, northeast boundary lines, termini for all habitat rehabilitation mitigation areas, and the 1418 maintenance access road using 2 strand smooth wire and T-posts. Any clearing of vegetation needed will be performed by the contractor to prepare an appropriate work location. All non-native vegetation and seeds cleared from the site will be disposed of at an approved green waste disposal facility.

3. The contractor shall implement vegetation rehabilitation using a combination of hydroseeding and hand seeding to achieve desired native species composition. The contractor shall install erosion control measures according to specifications as stated below in Section 5.
