2024 Diamond Valley Cut & Pile

Statement of Work

1 Introduction

1.1 Purpose

The Bureau of Land Management, Battle Mountain District Office, is seeking contractor services to conduct tree thinning and removal (manual cut and pile) treatments on roughly 286 acres of single-leaf pinyon pine (Pinus monophylla) and Utah juniper (Juniperus osteosperma). These treatments will be completed to establish a roadside fuel break in the foothills of Diamond Mountain. The service requested is the manual severing of whole trees. Trees within the treatment units will be removed in accordance with the Project Specifications found in Section

4.2. The purpose of the project is to reduce fuel loading.

1.2 Location & Access to Work Site

The work under this contract will be located within Eureka County in Nevada.

The treatment units are located within the following legal land descriptions (Mount Diablo Meridian), as shown on the attached maps:

• Diamond Valley Cut and Pile:

o T. 20 N., R. 54 E., Section 10, 11, 14, 15, 16 and 17

To access the roadside fuel break treatment area, take County Road 101 North from Eureka, Nevada for approximately 4 miles, turn right onto Mustang Street. Drive for approximately 1.5 miles, then turn left onto Melka Cottonwood Road. Drive for 2.7 miles and take a slight right onto Cottonwood Canyon Road. In 2.5 miles you will reach the Northmost end of the unit

(39.615622°N, 115.877697°W WGS 84).

There may be two-track roads which require a high clearance four-wheel drive vehicle as well as larger dirt county roads accessible by a low clearance two-wheel drive vehicle within and adjacent to the project area. Four-wheel drive vehicles are recommended on all non-paved roads due to the potential for unexpected inclement weather conditions as well as general road conditions.

There are no seasonal weather restrictions unless heavy rains occur or during periods of snow melt which may result in an intermittent work schedule due to muddy conditions. Work shall not occur if project implementation is creating excessive rutting (defined as ruts deeper than 2 inches in the regular road surface). Roads will be considered impassable when wet and access into the project area may be closed by the government during this time. Road maintenance may be permitted on existing roads with prior government approval; describe any planned maintenance or improvement work in your technical proposal.

1.3 Project Area Description

Vegetation in these areas is typical of the Great Basin and consists of a mixture of pinyon pine, juniper, sagebrush, bitterbrush, and grasses. The area primarily has slopes between 11-50 % though isolated steeper slopes may exist in some areas. Current tree densities within the units vary from 0% cover to over 60% cover.

It is the responsibility of the Contractor to consider tree densities and terrain while developing and proposing a performance timeline for this project.

1.4 Boundaries of Project Area

The project boundaries are not marked on the ground. Maps and GIS shapefiles of the project boundaries will be provided for upload into a GPS unit provided by the selected contractor. The selected contractor will be responsible for navigating with a GPS unit to stay within the project boundaries. The Government will not flag the unit boundaries and will only be on site for periodic work inspection.

Minor boundary adjustments to treatment units, up to 10% of the total project area, may occur for administrative purposes during project implementation that would potentially change the size or shape of treatment units. These adjustments WILL NOT change the total project size or the award amount.

1.5 Unique Features

Avoidance areas and other special features, if known and present, may be identified on maps or flagged within the treatment areas. There will be potential operating restrictions or areas subject to closure from April 15 to July 31st due to the migratory bird season. These timing restrictions shall be built into the proposal. No extensions will be granted due to these timing restrictions. The potential restrictions or closures would be pending the result of migratory bird surveys. Work shall not occur if project implementation is creating excessive ground disturbance. Work may resume only when weather conditions improve or work processes are altered to accommodate inclement working conditions, extensions may be granted based on weather or access related issues.

4 Project Specifications

4.1 Summary Table of Units and Treatment Methods

Table 1: Treatment Units and Treatment Methods Treatment Unit Treatment Method Treatment Specifications Total Acres

DV-roadside Thinning and Pile Cut and pile, leaving approximately 50 feet of canopy spacing within the treatment area.

Contractors are to submit a single bid for cut and pile treatments on a per acre basis using the provided Bid Schedule. A 10% reduction may be imposed due to unforeseeable culturally or environmentally sensitive areas discovered during pre-treatment inventory and monitoring.

However, final reductions are expected to be minimal.

4.2 Treatment Method: Tree Thinning and Piling – 286 Acres

Thinning and piling of pinyon and juniper trees will be conducted within the following specifications:

4.2.1 Boles shall be cut as close to the ground as possible with a target stump height of less than 8 inches;

4.2.2 Boles are to be cut in 5-foot lengths if the length of the tree meets or exceeds 10 feet in height from end to end;

4.2.3 Limbs (slash) from thinned trees shall be cut and piled in openings not immediately adjacent to tree boles or important cultural or wildlife locations;

4.2.4 Tree densities are to be reduced to about 17 trees per acre (TPA) or approximately 50-foot spacing between remaining tree canopies;

4.2.5 All other species as well as designated groups of trees (islands) or leave trees are not to be cut or disturbed or have a pile placed immediately adjacent to it. Preference for leave trees is ranked from highest (most desirable to leave) to lowest (least desirable to leave) in the following order:

4.2.5.1 Marked pinyon or juniper

4.2.5.2 Marked islands

4.2.5.3 Trees with nests

4.2.5.4 Mature, healthy juniper which exhibit old growth characteristics (Greater than 12” DBH, depth at breast height, or greater than 20’ tall).

4.2.5.5 Mature, healthy pinyon pine, (Greater than 12” DBH, depth at breast height, or greater than 20’ tall).

4.2.6 The by-product of cut and pile will be piles that are roughly exceed 10 feet in diameter and 6 feet in height consisting of limbs and boles that were cut down. At least 90% of the cut material, if not all the material, will be placed within these piles.

4.2.7 Piles shall not be placed on or within 3 feet of stumps. Piles shall be located outside the dripline of standing live trees.

4.2.8 Piles shall be compact, dirt and trash free, and piled in such a manner that will allow them to burn completely. Slash material that causes large air spaces in piles shall be cut into shorter pieces to facilitate compaction and eliminate air pockets within the pile. Smaller sized materials should be placed in the center of the piles to assist in ignition of the piles during burning.

4.2.9 Large portions of the treatment area may be within pile burning avoidance area, in which the Contractor may be responsible for conducting lopping of trees and scattering material throughout the site instead of piling for subsequent burning.

4.3 Schedule

All work performed on the project shall follow the schedule included with the technical proposal.

The schedule must be mutually agreed upon by the contractor and the Government during the initial awarding of the contract. If the contractor needs to deviate from the schedule or encounters difficulties during the implementation of the project, they shall immediately notify the Contracting Officer’s Representative or Project Inspector to discuss and approve any changes to the original performance schedule.

4.4 Measurement of Payment

Work will be measured and paid for by the number of acres that are completed to specifications.

The total will be rounded up to the nearest whole acre. Area measurements required under this Contract will be measured on a horizontal plane. Invoicing may occur no more often than monthly.

4.5 Start Date

Work shall start September 1st or as negotiated by the Contracting Officer or Contracting Officer’s Representative.

4.6 End Date

Work shall be completed by December 1th unless approved reasonable and excusable delays occur.

4.7 Period of Performance

September 1, 2024, to December 1, 2024

4.8 Level of Difficulty

Tree densities and over land travel are two factors that may limit production. The Contractor will be responsible for mitigating these factors to meet project completion benchmarks and the performance schedule.
