1. Project Description

Project Overview

This initiative, developed in response to the aftermath of the 2020 Slater Fire in Takilma, OR, encompasses targeted restoration efforts across three properties, totaling approximately 50 acres.

These properties, situated within the Upper East Fork Illinois River Watershed, include areas both in the uplands and the floodplains. The properties exhibit considerable variation in terms of the fire's impact, encompassing differences in burn severity, affected area, local ecological characteristics, topographical slopes, and individual landowner preferences.

Objectives

The project's primary goals are to mitigate future wildfire risks and enhance forest resiliency in the post-fire landscape. This involves the strategic removal of dead and decaying vegetation, as well as the revitalization of forested conditions aligned with an overarching natural ecology Forest Plan with a strong landowner collaboration. Site assessment and specific landowner objectives are outlined in detail in the site surveys.

Restoration Strategies

In regions impacted by high soil burn severity, the project's focus will be on the restoration of native species and the introduction of suitable vegetation to achieve the envisaged ecological balance.

Restoration efforts will encompass a blend of manual and mechanical strategies to manage competing vegetation, aligned with the distinct ecological requirements of the area and the objectives of the landowners. The project entails four tailored fuel treatment approaches, covering approximately 30 acres with mechanical treatment, 15 acres subject to manual hand-cutting, piling, and burning, and 5 acres designated for low-impact hand-cutting, piling, and burning.

Additionally, upland replanting will be conducted in all areas, with each site receiving a selection of locally adapted tree species. This selection is specifically tailored to enhance survivability, boost biodiversity, and improve overall forest vigor. The species chosen for each area have been carefully matched to the local conditions and ecological requirements to ensure the successful restoration and long-term health of the forest ecosystem. The specific requirements for each fuel treatment, essential for both site preparation and upland replanting, are thoroughly detailed in Appendix A: Technical Specifications For Service Work Items.

Appendix A: Technical Specifications For Service Work Items

Fuels Treatment 1: In-Unit Mechanical Site Preparation

1. Fall all dead and fire killed trees greater than 6.1 inches and less than 26 inches DBH.

Trees must be limbed, bucked, and staged near the existing road system for landowner use.

2. Fall all dead and fire killed trees greater than 2 inches and less than 6 inches in diameter in units identified in detailed unit sheets (Dead trees are defined as having no green needles, or leaves).

3. All trees between 2” DBH to 6” DBH, and other large woody fuels, shall be mechanically treated to reduce the accumulation of those fuels and minimize competing vegetation for future replanting efforts (Treatment should be done by mastication and/or chipping).

4. Mastication should be done by a boom mounted masticator/mulcher with a boom length of at least 28’ to be capable of treating areas with difficult, or limited accessibility, and to reduce soil compaction in the treatment area. Tracked Masticators may be permitted in some areas, but only under approval from the contracting officer.

5. Limit wood chip depth to less than 5 inches, discontinuous, to avoid nutrient imbalances, excess surface fuel loading, and interference with the establishment of reforestation efforts.

6. No mechanical entry or vegetation treatment shall occur within 50 feet of all perennial and intermittent streams, springs, seeps, and wetlands. The no entry/no disturbance buffer will extend from the outer edges of the stream channel or wetland, including springs, seeps, wet meadows, or other wetland features as shown on Contract Area Map.

7. Ground-based equipment will be limited to slopes less than 35%.

8. Maximum stump height shall be 12” above natural obstacles.

Fuels Treatment 2: Roadside Mechanical Treatment (Mastication/Chipping)

1. All equipment will stay to the existing road system, unless otherwise agreed upon.

2. All trees between 2” DBH to 6” DBH, and other large woody fuels, within 20’ of the roadside

(40-foot treatment zone) shall be mechanically treated to reduce the accumulation of those fuels and minimize competing vegetation.

3. Mechanical treatment should be done by a boom mounted masticator/mulcher with a boom length of at least 28’ to be capable of treating areas with difficult, or limited accessibility, and to reduce soil compaction in the treatment area. Tracked Masticators may be permitted in some areas, but only under approval from the contracting officer.

4. Limit wood chip depth to less than 5 inches, discontinuous, to avoid nutrient imbalances, excess surface fuel loading, and interference with the establishment of reforestation efforts.

5. No mechanical entry or vegetation treatment shall occur within 50 feet of all perennial and intermittent streams, springs, seeps, and wetlands. The no entry/no disturbance buffer will extend from the outer edges of the stream channel or wetland, including springs, seeps, wet meadows, or other wetland features as shown on Contract Area Map.

6. Ground-based equipment will be limited to slopes less than 35%.

7. Maximum stump height shall be 12” above natural obstacles.

Fuels Treatment 3: Hand Cut, Pile, and Burn

1. All trees 2” DBH to 6” DBH and other large woody fuels such as broken tops shall be treated as slash and be piled for disposal and burning.

2. Hand Piles: Unless otherwise agreed, all trees less than 6 inches and all slash generated while cutting shall be hand piled. Hand piles shall be constructed by laying limbs, stems, cut boles and other slash in the piles parallel with each other and perpendicular to the slope.

Minimum hand pile size shall be 4 feet in diameter by 4 feet in height, maximum hand pile size shall not exceed 6 feet in diameter and 8 feet in height. All material shall be trimmed so as to not extend from the pile profile in any direction. Piles shall be compact and free of soil.

Hand piles should be placed a minimum of 25 feet from any live tree, bearing trees, land survey marked or posted trees, fences, and designated items/areas to protect. Piles shall not be located in draws, riparian areas, roads and/or non-treatment areas, near standing snags, on logs and stumps. Cover hand piles with a minimum 4-foot by 4-foot polyethylene plastic.

3. All slash piles shall have a fire line dug into mineral soil around the entirety of the pile.

Fuels Treatment 4: Hand Cut, Pile, and Burn

1. The contract map area (Stone Property) designating Fuels Treatment 3, aims to perform the minimum amount of site preparation necessary for successful replanting. This landowner wishes to maintain a low level of vegetation removal and disposal.

2. All standing trees greater than 3” DBH and other large woody fuels shall be left in place, unless posing a significant hazard to the contractor.

3. “No-cut” living shrubs will be flagged by the landowner and care will be taken by the contractor to insure no damage occurs.

4. Tanoak and Madrone stump sprouts to 3 upright sprouts per stump.

5. Competing vegetation (up to 3” DBH) shall be removed in 3-4’ diameter. Cleared areas should be completed in 12’ x 12’ increments to prepare the site for future replanting efforts.

6. Unless otherwise agreed, all vegetation removed and slash generated while cutting, shall be hand piled (lop and scatter allowed in some areas). Hand piles shall be constructed by laying limbs, stems, cut boles and other slash in the piles parallel with each other and perpendicular to the slope. Minimum hand pile size shall be 4 feet in diameter by 4 feet in height, maximum hand pile size shall not exceed 6 feet in diameter and 8 feet in height. All material shall be trimmed as to not to extend from the pile profile in any direction. Piles shall be compact and free of soil.

Piles shall not be located in draws, riparian areas, roads and/or non-treatment areas, near standing snags, on logs and stumps.

7. Piles shall be left uncovered (no plastic)

8. No Diesel shall be used for pile burning.

Tree Planting: Site-Specific and Mixed Species Reforestation

1.) Seedlings will be provided to the contractor by the project sponsor and will be sourced from multiple nurseries. Species and quantities have been tailored to each site and are listed in the Planting Specifications Table.

2.) Seedlings are likely to be Bare-Root (12” +) and will likely require winter planting to avoid mortality caused by dry-out.

3.) Some areas may require additional spot preparation, an 18” square may be scalped out with a planting hoe or shovel at the time of planting. Remove all heavy sod and competitive plant growth.

4.) Seedlings should be planted maintaining a distance of 12 feet by 12 feet between them.

Additionally, the arrangement should facilitate interplanting in clusters, with each cluster containing 18-30 seedlings of the same species. This approach is illustrated in an example provided in the image below.

5.) Plant seedlings into bare mineral soil —no needles, twigs or debris in the planting hole.

6.) Take care not to bury foliage or to leave roots curled back or exposed to the air.

7.) Pack soil firmly around the entire root system, leaving no air pockets.

8.) For Roadside Replanting, a Ten-foot buffer zone shall be left on either side of the road prism to avoid obstructing future road access. Tree spacing may be reduced in these areas to achieve the desired stocking density.

9.) In Riparian areas (Ormsby Unit), specific species have been selected that align with local ecology. Interplanting will be required in these areas and stock spacing may vary.
