About this file
This is a Scope of Work document for tree removal and vegetation management services at Tamarac National Wildlife Refuge in Minnesota.
The U.S. Fish and Wildlife Service requires a contractor to clear and trim vegetation along approximately 3 miles of refuge trails to create a safe travel corridor. The work encompasses two specific trails: South Twin Lakes Trail (1.12 miles) and South Tamarac Dike Road west of the pump house (1.88 miles), located approximately 25 miles northeast of Detroit Lakes, Minnesota. The contractor must cut all trees and brush within a 30-foot-wide trail corridor (15 feet from centerline on each side) at ground level, with stumps not exceeding 3 inches in height. Trees 2 inches in diameter at breast height (DBH) or greater must be removed using mechanical mowing, sawing, mulching, or chainsaw methods. Additionally, the contractor must trim overhead limbs and branches to 15 feet in height using mechanical equipment such as aerial lifts or brush-cutting attachments, creating smooth cuts with no more than 3 inches of branch stub remaining. Large trees (24 inches DBH or greater) of white pine, red pine, or white oak will be identified and marked by USFWS and will not be cut, though overhead limbs on these trees must be trimmed. All cut material must be lopped, scattered, or piled at least 5 to 30 feet off the trail, with pile sizes not exceeding 10 feet by 10 feet by 10 feet. The contractor must obtain appropriate permits and liability insurance, coordinate work schedules with refuge staff (Alisha Haken, 218-849-9867), and complete all work between September 1, 2026 and March 31, 2027. The contractor is responsible for furnishing all labor, equipment, supplies, and materials, while the government will provide trail maps and marking of large trees and trail width references.

SCOPE OF WORK
Tree Removal Along Refuge Trails
U.S. FISH & WILDLIFE SERVICE
Tamarac National Wildlife Refuge
35704 County Highway 26
Rochert, MN 56578
OBJECTIVE
Cut trees and brush within a 30’ trail, limb overhead trees and branches to 15’ in height along Refuge Trails.
BACKGROUND
Many of the administrative and public use trails have become overgrown with trees and brush. Many miles of trails throughout the refuge need limbing and brushing or widening. The encroaching trees and overgrown branches within the driving corridor limit passage or access, lead to vehicle and equipment damage, and obstruct visibility for two-way traffic.
Identified in this scope of work are 2 trails that are open to vehicle traffic by the public, tribe, or refuge staff and comprise of about 3 miles of total trail length to be limbed and cleared.
LOCATION
Tamarac Refuge is located in Becker County. The project sites/trails are approximately 25 miles northeast of Detroit
Lakes, MN and 45 miles northwest of Park Rapids, MN. Specifically, this work will take place on approximately 3 miles of trail in total, including South Twin Lakes Trail (1.12 miles) and the South Tamarac Dike Road west of the pump house
(1.88 miles). Each trail entry has adequate space for off-loading heavy equipment and staging a semi-truck and trailer.
South Twin Lakes Trail:1.12 miles
South Tamarac Dike Road (west of pumphouse): 1.88 miles
INTENDED USE
Service to be delivered is to cut trees and brush within 30’ trail, limb overhead trees and branches to 15’ in height, and clear or mulch slash, trees or brush to create a clear travel corridor along 3 miles of refuge trails with an overhead clearance of 15’ to achieve project goals.
SCOPE OF WORK/TASKS
Contractor is required to garner appropriate permits and certificates of insurance liability. Contractor will maximize work time and efficiency on site, minimize use of and traffic on refuge roads, and reduce overall transportation/disposal costs with fewer trips. Contractor will furnish all labor, supplies, materials, equipment, and supervision to perform the action items specified herein:
a. Clear trees along established trails. Cut all trees and brush of varying diameter at breast height (DBH) at ground level to a width of 30' (15’ from centerline on each side of the existing trails). All trees 2 inches DBH or greater must be cut as low to the ground as possible; with the remaining stump height not to exceed 3 inches.
Cutting can be done by mechanical mowing, sawing, mulching, tree shear, or chainsaw. Downed trees and brush will be mulched, mowed, or laid to the side (at least five feet off the trail), or piled for removal at a later date by contractor or USFWS staff.
b. Trim overhead limbs. Cut overhead limbs and branches to 15’ in height within the 30’ width of the trail.
Remove any overhanging limbs or branches to 15’ in height from trees originating outside of the 30’ trail. All cut material must be laid to the side (at least five feet off the trail) or piled for removal at a later date by contractor or
USFWS staff. Cutting will be done by mechanical sawing or grinding using a Loftness Kwik-Trim, Jarraff, Slashbuster brush cutting attachment, aerial lifts, or other like equipment so to create smooth, clean cuts at the trunk of the tree with no more than 3” of branch stub remaining.
c. Tree and Brush Material: Material will be lopped and scattered off of the main trail and drug into the unit (min
20’). Piles can be created at a distance of 30’ off the main trail and size of piles need to be no greater than
10’x10’x10’ and tightly packed.
d. Large Trees: Trees such as large (24” DBH or greater) white pine, red pine, or white oak within the 30' trail
Tamarac National Wildlife Refuge Page 2 corridor will not be cut. These trees will be identified by USFWS and clearly marked. Overhead limbs or branches will be removed to 15’ on these trees.
e. All cutting must remain within the 30-foot wide established trail corridor. Trails can be staked or flagged periodically to provide a reference, if the contractor prefers. It is the responsibility of the contractor to stay within the 30' trail.
f. Care should be taken to minimize the rutting/gouging of the ground and trail while working.
