Las Cienegas National Conservation Area Grassland Restoration Project
Mechanical Mesquite Reduction Yucca Ash Treatment Unit
Statement of Work
Background and General Scope
A. General Scope The Bureau of Land Management (BLM) is seeking to perform a mechanical mesquite reduction treatment on approximately 998 acres in the Yucca Ash treatment unit, within the Las Cienegas National Conservation Area (LCNCA). Of the approximate 998 total acres, 284 acres are located in Pima County and 714 acres are located in Santa Cruz County. The retreatment unit is on lands under the jurisdiction of the BLM and is generally located in T19S R17E S31,32,33/T20S R17E S5,6 (see Appendix B). This treatment will be implemented using a service contract.
B. Background The BLM is implementing a grassland restoration project on the LCNCA, one aspect of the restoration project is mesquite reduction. The current method of mesquite reduction is mechanically grubbing the mesquite out of the ground with equipment.
This includes removal of the root ball from the ground and ensuring that all roots are broken or severed from the root ball.
Work to be Performed
The contractor may utilize rubber-tired or tracked equipment to grub and remove all visible regrowth mesquite trees and stumps found within the treatment unit. The contractor will windrow grubbed mesquite across the treatment unit.
A. Grubbing
Rubber-tired or tracked equipment will be utilized to grub all visible mesquite trees found within the treatment unit, leaving small clusters of 12 foot or taller mesquite trees (4-5 per acre).
Remove root ball from the ground ensuring that all roots are broken or severed from the root ball.
Back fill any holes generated from the grubbing process to ensure that no holes are deeper than 6 inches.
Loosely place slash in a windrow.
The unit is a total of 998 acres with an estimated tree density break out of:
o 601 acres: 0-100 trees per acre, generally 6 ft tall and under.
o 394 acres: 100-200 trees per acre, generally over 6 ft tall.
Equipment Requirements The BLM requires the following equipment specifications as a minimum standard for equipment capabilities, these requirements will allow for sufficient equipment capabilities to handle size class of trees:
Four wheel drive.
Enclosed cab.
96 hp.
Digging force-bucket 14,800 lbs.
Digging force-crowd 8700 lbs.
12” bucket or narrowest bucket available for equipment.
Toothed, heavy duty bucket
Site Visit Currently a site visit is not scheduled as this area is open to the public. All interested parties are encouraged to visit the location prior to submitting their quote.
Safety Concerns The contractor will be responsible for completing the contract in a safe and effective manner that is consistent with any applicable safety regulations, polices, or guidelines.
The project area falls within the international border watchout zone see appendix C. for border watch out guidelines.
Cultural Concerns If any cultural artifacts are uncovered during the grubbing process the contractor will immediately stop digging and contact the BLM Contracting Officer’s Representative (COR). The COR will coordinate with the BLM archaeologist if artifacts are uncovered.
Any known areas of cultural concern will be identified (flagged or marked) prior to the start of the contract. These areas will be excluded from any ground disturbance. A georeferenced map will be provided by the BLM upon award.
Deliveries and Performance The Contractor shall perform in accordance with the requirements of this contract.
Schedule and Calendar Performance shall be completed between October 1, 2024 – June 30, 2025.
In the event the timeline may not be met due to adverse weather conditions, and/or circumstances outside of the control of the Contractor, extra time may be added to portions of the field work phase (grubbing). The Contractor will be required to inform the COR of any circumstances that may require an extended amount of time. All extensions will be granted on a case-by-case basis at the CO’s discretion, after coordination between the CO and the Contractor.
Deliverables The contractor shall deliver the following as a part of their quote for grubbing mesquite and windrowing slash on unit.
Example of three previously completed contracts of a similar magnitude and nature.
Cost per acre to grub and windrow all the visible mesquite from the treatment unit.
Example of the type and number of equipment to be used for grubbing of mesquite (description of equipment make, model, and capabilities).
Quality Control Plan.
The Contractor shall deliver the following during implementation of the contract:
Grubbing of 100% of visible mesquite trees, leaving small clusters of 12 foot or taller mesquite trees (4-5 per acre).
Government Furnished Property The contractor is responsible for supplying all equipment, labor, supplies, materials, etc needed to complete the contract. The BLM will not furnish any equipment, supplies, materials, or labor. The BLM will provide georeferenced maps of the treatment units.
Coordination The Contractor shall coordinate closely with the assigned BLM Contracting Officer’s Representative (COR) and assigned Project Inspectors (PI) throughout the duration of the project, per the developed timeline and schedule. A pre-work conference will be required at the prior to contract implementation.
The contractor will coordinate with the BLM COR/PI daily or an as needed basis.
Progress will be tracked using GPS units to count the number of acres completed. The contractor and the BLM COR/PI will establish a schedule of progress tracking during the pre-work conference. A completed acre is defined as an acre where all regrowth mesquite has been grubbed and windrowed according to contract specifications.

11. Unattended vehicles are subject to being damaged or stolen – lock up every time. Travel with your doors locked.
12. Illegal uses in the Watchout area are likely.
13. There is a heightened risk of biological contamination associated with improper waste disposal.
14. Always know your location and be able to describe it.
15. Let others know your expected route and destination(s) (check-in and check-out).
16. Expect to encounter Interagency Law Enforcement and interdiction actions and activity.
