About this file
This document is a Statement of Objectives (SOO) for a Bureau of Land Management (BLM) Forestry Stewardship project in Oregon. The primary objective is to reduce wildland fire risks, improve forest health, and generate employment by managing forest stands and juniper woodlands through integrated stand management techniques. The project involves mechanical and manual logging activities, including ground-based and cable logging, mechanical snag creation, brushing, tree cutting and piling, and woody debris removal.
The scope encompasses forestry work across BLM-administered lands, with contractors required to furnish personnel, equipment, and labor to execute various forestry management tasks. Key specifications include using specific logging equipment like mechanical harvesters, skidders, and cable skyline systems, maintaining strict environmental and safety standards, and following detailed guidelines for tree cutting, yarding, and slash management. The project will be executed through task orders under a 10-year multiple-award Indefinite Delivery/Indefinite Quantity (IDIQ) contract, with tasks anticipated to be issued as firm-fixed-price task orders.

STATEMENT OF OBJECTIVES
1.0 GENERAL
1.1 Description - Contractor shall furnish all necessary management, labor, supervision, equipment, materials, transportation, supplies, and incidental services to perform this requirement. A Stewardship project is designed to provide an integrated approach to stand management on forest stands and juniper woodlands of varying sizes and densities.
1.2 Objective - The objective of this project is to reach an end result that will:
| • | Reduce the risk of high intensity wildland fire to life, property, and natural resources on lands managed by the BLM. |
| • | Improve forests health through stand density reduction and reduction of hazardous fuel loads. |
| • | Treat fuels by promoting utilization of timber, biomass, and unmerchantable material. |
| • | Generate employment opportunities. |
1.3 Location/Access - The project areas are located within the administrative boundaries of BLM. See attached vicinity map. Project area(s) are normally accessible by a standard pickup on forest roads. A four-wheel drive vehicle may be required. The Government assumes no liability to perform special road maintenance to keep roads open to the project areas.
1.4 Security of materials – The Contractor may leave their equipment at the work site. However, the Government is not responsible for the equipment if it should be lost, stolen, or damaged.
1.5 Boundaries - Unit boundaries are marked with ribbon or designated on PDF maps or similar mapping software. The project maps show reserve areas, some of the physical and topographical features of the units, as well as delineated areas within the units which require special treatment.
1.6 Fire Precautions – Contractor must follow all applicable laws and regulations regarding fire season and associated restrictions and requirements.
1.7 Unique Features of Project Area - Any unique feature specific to each unit will be listed on task order unit maps.

Cord - A stack of fuelwood which measures 4 x 4 x 8 ft. or 128 ft3, including wood, bark, and empty space within the stack.
Damaged Trees - Any Contractor-caused alteration or injury to the tree or root system which may cause death, loss of vigor, or will negatively affect growth, including, but not limited to, severance of the main stem or terminal leader, delimbing, scraping, debarking, or uprooting.
Deck - A stack of logs or the action of stacking logs.
Designated Skid Trail - A trail flagged by the Contractor prior to cutting and approved by the COR/PI to operate designated equipment on.
Diameter Breast Height (DBH) - The diameter of a tree measured at breast height, 4.5 feet above the ground on the uphill side.
End-Lining - Pulling or winching felled trees or slash by means of cable drawn out from the skidder or skidding vehicle in the following situations:
| · | Where the ground is too steep for mechanized equipment |
| · | Where the ground is required to be protected from disturbance by heavy equipment |
| · | Where a felled tree is in a group of trees and damage to the group would be excessive if the tree were removed by a skidder |
Firewood - Wood that does not meet the Sawlog, Biomass, Clean Chip, or Post & Pole definitions described herein and/or that is transported off the site in lengths less than 8 feet long and intended for use as fuelwood. This material shall be priced in cords with volumes determined by the Government.
Hazardous trees - standing live or dead trees, with evidence of insect infestation, deterioration, or physical damage to the root system, trunk, or stem. The degree and direction of lean is also an important factor when determining if a tree is a hazard.
Hardwood Tree - A deciduous tree which usually has a single well-defined trunk and normally attains a height of greater than twenty (20) feet at maturity and has broad leaves. Examples include, but are not limited to, species such as Pacific madrone, chinquapin, tanoak, canyon live oak, big leaf maple, red alder and ash.
Hog Fuel- See Biomass - Any type of wood product that can be burned for fuel at pulp mill facilities to generate electricity but can't be classified as chips, shavings, bark, or sawdust.
Landings - A loading point where logs are collected preparatory to further transportation, loaded on trucks and also any other location that became a destination for yarded woody material.
Large woody debris - Portion of a tree that has fallen, or been cut and left in the woods. Usually refers to pieces at least 20 inches in diameter.
Leave Tree – Any tree marked for retention and/or described in this contract to be reserved from cutting. Additional leave trees may be specified on project maps.
Loading point - Any landing or other area in which logs and biomass material are capable of being loaded for transportation out of the project area.
Lop - Trim by cutting off branches, twigs, or stems.
Manual Work – Work that does not require the use of heavy equipment. Most work is performed by hand; some bid items may require light use of chainsaws, ATV’s, or trucks.
Mechanical Work – Work will primarily require the use of heavy tracked or tired equipment.
Sawlog (Merchantable Timber) - The Minimum Material Specification is as follows (this may be adjusted on a per task order basis):
Schedule of Minimum Material Specifications
| Species and Products | Length | Diameter | |
| (inside bark at small end) | Net Scale | ||
| Logs of all species | 16 feet | 6 inches | 33 1/3% of gross volume of any log segment |
Objectionable Material – Objectionable material is defined as debris or any foreign matter.
Older junipers - Juniper that originated in the “pre-settlement” period, before 1870. It is assumed that these trees are growing on sites that they are adapted to, since they began growing there under “natural conditions” when natural processes (including lightning fires) determined vegetation patterns. Older junipers are usually found in rocky areas where vegetation is sparse and natural fire frequency is low. Some typical characteristics of older juniper are:
| • | Crown is flat, rounded, broad at top, or irregular (as opposed to the more pointed tops of younger trees) |
| • | Spike top |
| • | Numerous dead branches |
| • | Branches covered with coarse, bright yellow-green lichen (Letharia, or wolf lichen) |
| • | Large diameter lower branches |
| • | Large diameter trunk relative to height |
| • | Trunk has spirally-twisted bark, deep furrows |
| • | Hollow trunk |
It is rare for an older juniper to have all of the above features, but more commonly will have at least three or four. Also, older junipers are not always the largest trees; on drier, rocky sites, they can be short, stubby, gnarly trees.
Post & Pole - Wood sized approximately six inches in diameter and seven feet long used as a fence post and/or poles and does not meet the Sawlog definition. This material may be sold on a cord or ton basis as shown on the task order.
Preferred Species - The list of species in order of most desired to least desired in a given area. This information may be provided in a task order.
Project Area - The area identified on the task order for treatment using any of the items in this contract.
Reserve Area - An area where no activity is permitted.
Reserve Trees - Generally those trees designated by the Government to be left uncut. Each task order will include a specific description of reserve trees for that project.
Silviculture Summary Prescription (SSP) - Specific instructions provided with each task order for individual treatment units that summarize desirable leave trees and requirements for selecting the leave and/or reserve trees. The prescription is based on the overall composition and condition of the stand and is intended to be a guideline for achieving a desired stand condition. The Contractor shall use his/her silvicultural knowledge to identify and designate leave trees, desired species composition, and adjust to any conditions within the stand and notify the COR or PI of any conditions not addressed in the prescription. Designation can be by paint, description, or prescription. In some cases, a small area will be marked and cut to ensure the Contractor understands the specifications.
Slash – All woody material that has been cut, but not removed from the contract area during the primary removal operation. Typically includes brush, broken tops, limbs, cull logs, pieces of logs damaged reproduction, saplings, and poles which were caused as a result of felling and yarding operations. This includes old slash existing prior to timber sale entry.
Station-In reference to road construction/maintenance a station is equal to 100 feet.
Stump - The lower end of a tree with roots attached remaining in the ground after the tree has been cut.
Submerchantable Material (Non-Sawlog) – Vegetative material that does not meet the definition of Merchantable Timber (Sawlog).
Timber - standing trees which are capable of being measured in board feet and cubic feet.
Trespass Trees - Any reserve trees which have been cut and/or removed from the woods.
Yarding – the conveyance of logs or trees or portions thereof, by ground based, cable, balloon, or helicopter yarding systems from the area of falling or cutting to the landing or loading point for removal. Yarding is generally accomplished using mechanical equipment.

5.7.13 Additional timber that is obstructing needed skid roads, trees designated for cutting, cable yarding roads, hazardous to workers, needed for guyline, tailhold, and/or tieback trees, and severely damaged from the normal conduct of felling or yarding operations to meet all applicable State safety laws, codes or regulations. This timber must be cut or removed so that the contractor can continue active falling and yarding operations. The contractor will be authorized to cut and remove such additional timber provided, however, that:
5.7.14 Before cutting and removing any trees necessary to facilitate logging in units, the Contractor shall identify the location of the skid roads, yarding corridors, landings, and danger trees on the ground in a manner approved by the COR/PI at the pre-work conference and documented in the Logging Plan. Said Contractor identification of trees to be cut and removed does not constitute authority to proceed with cutting and removal.
5.7.15 All skid roads upon which timber is identified by the contractor to be cut and removed in accordance with this special provision must be necessary for the safe and expeditious removal of timber sold under this contact and shall be limited to the minimum width necessary for yarding of logs with a minimum of damage to reserve trees, however, unless otherwise approved in writing by the COR/PI, the width of each skid road shall be limited to 14 feet.
5.7.16 The Contractor may cut and remove additional timber after the COR/PI has approved the trees and designated them for removal. The volume and value of the timber that will be charged to the contractor for this additional timber will be determined by the COR/PI in accordance with Bureau of Land Management prescribed procedures.
5.7.17 If a tree or snag is determined by the contractor to be an imminent threat to safety, the contractor may immediately fall the tree without prior approval. Once the tree has been felled, the contractor must immediately contact the COR/PI and notify them of the action. The tree will be left where it lays and the cut end of the tree and stump shall be marked with a large “X”, cut with a chainsaw, and the “X” will be painted with red paint. The felled tree cannot be removed until the COR/PI physically inspects it.
| 5.7.18 | The Contractor agrees that sale of this additional timber shall be accomplished by a unilateral modification of the contract executed by the Contracting Officer. |
| 5.7.19 | This authorization for the Contractor to cut and remove additional timber prior to the execution of a modification may be withdrawn by the Contracting Officer if the COR/PI determines that the Contractor has cut and removed any tree not previously marked and approved for cutting by the COR/PI. |
| 5.7.20 | If authorization is withdrawn, the Contracting Officer shall issue a written notice to the Contractor that the sale of additional timber under this special provision is no longer approved. In this case, the Contractor shall inform the COR/PI at least one (1) working day prior to the need for cutting and removing any additional timber. The Contracting Officer may issue a written order to the Contractor to suspend, delay, or interrupt any or all contract work for the period of time deemed necessary and appropriate for the Government to safely measure and mark additional timber. |
| 5.7.21 | Treatment of Slash and Landing Piles |
| 5.7.22 | All logging slash shall be removed to a landing location and piled unless specified by the COR/PI. |

| 7.0.4 | Where trash or debris is on the road surface, remove debris prior to blading so debris is not mixed into potholes or surfacing materials. |
| 7.0.5 | Blade and shape the existing traveled way and shoulders, including turnouts, unless otherwise ordered. |
| 7.0.6 | Blading shall produce a surface which is uniform, consistent to grade, and crowned or cross-sloped as indicated by the character of the existing surface, to at least 1/4 inch per 1 foot of width, but not more than 3/4 inch per 1 foot of width (2% to 6 %). |
| 7.0.7 | Thoroughly loosen surfacing material to no less than 2 inches depth or 1” below the bottom depth of potholes or washboards whichever is greater. |
| 7.0.8 | Scarification to facilitate cutting to below the bottom of potholes or corrugations will be considered incidental to blading. Do not scarify deep enough to cause contamination of the surfacing material. Contaminated material created by the contractor shall be removed by the contractor and replaced with approved material at no additional cost to the government. |
| 7.0.9 | When water application is included; apply water during blading when sufficient moisture is not present to prevent segregation of surface materials. |
| 7.0.10 | Blading when excessive moisture is on the surface that causes runoff of materials and surface water is prohibited. |
7.0.11 Shape existing native rock or aggregate surfaced drainage dips to divert surface runoff to existing outlet devices, ditches, and discharge location.
7.0.12 Establish a blading pattern, which provides a uniform driving surface, retains the surfacing on the roadbed, and provides a thorough mixing of the materials within the completed surface width. Remove any oversized material (greater than the largest surfacing material dimension) from the road surface or shoulders and place outside the roadbed. Oversized material may be scattered off the roadbed if there is free drainage and material does not contain road grade rock. If oversized material does not meet the above criteria to be left, the oversized material must be removed and transported to an approved waste area.
Shape and compact the traveled way and shoulders using one of the following methods:
Method A – Compact the aggregate by operating spreading and hauling equipment over the full width of each layer of aggregate.
Method B – Moisten or dry the aggregate to uniform moisture content suitable for compaction. Operate rollers over the full width of each layer until visual displacement ceases, making no fewer than three complete passes. (A pass is defined as a single complete coverage of the surface).
Method C – Ensure that materials produced by pit-run and grid rolling are visually moist and compacted using operating compaction equipment over the full width of each layer until visual displacement ceases.
7.0.13 Roads will be measured on centerline miles to the nearest tenth for single lane roads. Double lane miles must be at least 22 feet wide and will be counted as two single lane roads. Roads must be identified as double lane.
7.0.14 Watering- This work shall consist of furnishing and applying water required for the finishing and reconditioning of existing roadbeds, laying dust, dust abatement during active haul, or for other uses in accordance with these specifications.
Water, when needed for compaction or laying dust, shall be applied at the locations, in the amounts, and during the hours as directed by the COR. Amounts of water to be provided will be the minimum needed to properly execute the compaction requirements in conformance with these specifications, and for laying dust during work periods.
Water trucks used in this work shall be equipped with a distributing device of ample capacity and of such design as to ensure uniform application of water on the roadbed.
Water required under these specifications shall be obtained at a location designated by the COR Use of the water source is subject to applicable State water regulations.
