About this file
This document is a design features guide for the Corral G-Z Integrated Resource Stewardship Contract, issued by the USDA Forest Service Bly Ranger District in July 2026. Mandatory Item 4 requires the contractor to develop a Project Area Implementation Plan for the Grizzly sale by refining and finalizing unit pools for commercial timber harvest and service work. Timber treatment units must be categorized into one of four types: ponderosa pine, dry mixed conifer, moist mixed conifer, or transmission-line treatment with timber removal. Service work units fall into eight classifications including transmission line treatments, cut-skid-and-deck operations, and tree thinning for restoration purposes. All timber and service units must be ground-verified by the contractor prior to inclusion in the implementation plan, with treatments applied according to prescriptions in Attachment 4.
Unit delineation must follow specific criteria including treatment type, applicable DxP Prescription based on plant association groups, and prescription categorization for transmission line units. Transmission line treatment units and cut-skid-and-deck operations for control features and natural stands cannot exceed 250 acres each. Unit layout requirements mandate that boundaries along private property lines be flagged, tagged, painted, and GPS'ed per the Forest Product Accountability Action Plan. Shared boundaries between timber units require flagging, tagging, and painting. The contractor must maximize use of virtual and discernible boundaries, ensure all units conform to Project Design Criteria including slope restrictions and riparian buffers, and reserve 15-20% of timber unit area for wildlife retention areas delineated virtually without physical marking.

Corral G-Z IRSC Design Features
One objective of the Corral G-Z Contract is for the contractor to carry out sale preparation for future timber sales. This document provides context and outlines objectives to guide the work and ensure the project meets its intended goals.
Mandatory Item 4: Project Area Implementation Plan (Grizzly)
The focus of Item 4 is to refine and finalize the unit pools for commercial timber harvest as well as service units. The contractor will develop an implementation plan for the Grizzly sale.
Identification of Timber Treatments Timber treatment units will be categorized as one of the following:
a) ponderosa pine
b) dry mixed conifer
c) moist mixed conifer, or
d) transmission-line treatment with timber removal.
Timber units will be treated according to the prescriptions in Attachment 4. All timber units shall be ground-verified by the Contractor prior to inclusion in the Project Area Implementation Plan.
Service work shall only be included where necessary to achieve the desired results, avoiding unnecessary treatments in areas that don’t require them.
Service work units shall be classified as one of the following:
i) Transmission Line Treatments (Large-tree thinning without timber removal)
ii) Transmission Line Treatment (Small-tree thinning)
iii) Cut, Skid, and Deck – Control Features
iv) Cut, Skid, and Deck – Timber Units
v) Cut, Skid, and Deck – Natural Stands
vi) Small and Large Tree Thinning – Whitebark Pine Restoration
vii) Small Tree Thinning - Old Growth
viii) Conifer Removal – Aspen
Service work units will be ground-verified by the contractor, and a determination will be made as to whether part or all of the unit in question requires service work according to the prescriptions listed in Attachment 4. Potential service units may be expanded beyond the extent of the polygons provided by the Forest Service if deemed necessary during ground verification. If, during the reconnaissance of potential timber units, the contractor finds areas without commercial value which could nonetheless benefit from one of the treatments listed above, these shall be added as units to the service plan.
Unit Delineation Units shall be delineated according to the following criteria:
- Treatment type
- Applicable DxP Prescription. For ponderosa pine and mixed conifer units, this will be determined by the predominant plant association group (PAG) in which the timber unit is located. A shapefile
Bly Ranger District | July 2026 containing PAG layers will be provided to Contractor after contract award.
- Transmission line units must be categorized according to two potential prescriptions listed in
Attachment 4: large-tree thinning or small-tree thinning. Units must also be categorized as having adequate access for skidding and roadside decking (timber units) or not having adequate access (service units).
- The units for Transmission Line Treatments, Cut, Skid, and Deck – Control Features and Cut, Skid, and Deck – Natural Stands may not exceed a maximum size of 250 acres each.
- Overlapping treatments shall share a common boundary.
o For example, if only part of a timber removal unit requires CSD, it shall be split into two separate units: Ex) Unit 1: Timber removal and CSD, Unit 2: Timber removal.
This delineation best supports Forest Service activity tracking.
Unit Layout
- Both timber and service work unit boundaries that follow private property lines shall be flagged, tagged, painted, and GPS’ed according to the regulations in Attachment 1 – Forest Product Accountability Action Plan.
- Shared boundaries between two timber units shall be flagged, tagged, and painted.
- Contractor is to maximize the use of virtual and discernible boundaries relative to the instructions in Attachment 1 – Forest Product Accountability Action Plan for both timber units and service work units.
- Ensure that all timber and service units conform to the requirements listed in Attachment 5 – Project Design Criteria. These include, but are not limited to, slope-based restrictions, riparian buffers, and species-specific leave areas.
- Timber units must reserve at least 15-20% of unit area for wildlife retention areas. Wildlife retention areas must meet the requirements listed in Attachment 5 – Project Design Criteria.
Additionally, all wildlife retention boundaries shall be delineated virtually. Do not flag, tag, or paint wildlife leaves.
