Project Need
Need For Project:
The Cook WMA was acquired by UDWR in 2025 and is a stronghold for Mule deer, wintering elk, and Bighorn Sheep. The property was privately owned prior to UDWR acquisition and used primarily for domestic livestock grazing and hunting. After UDWR acquisition, the property needs the appropriate fencing/maintenance, signage, and water developments (guzzlers) to help protect the property and begin management for wildlife. Vegetation projects would help promote Aspen stands and diversify plant communities.
Objectives:
Objectives are to replace a nonfunctioning water line and trough, upgrade a section of fencing that is subject to vehicle trespass, and perform forestry practices to enhance aspen stands on the WMA.
Project Location/Timing Justification (Why Here? Why Now?):
The property was acquired in 2025 and UDWR needs to perform the foundational projects to get this property on track to be managed as a public WMA.
Relation To Management Plan:
UDWR Habitat staff will begin the process of developing an HMP for the property in 2026.
Fire / Fuels:
Timber harvesting will help create fuel breaks in the dense, conifer dominated stands on the property.
Water Quality/Quantity:
Replacing the water line and trough will help provide additional water sources for wildlife and livestock, helping distribute forage use across the WMA.
Compliance:
New ground disturbance for the timber harvest area will require arch clearance. It is anticipated this will be such small scale, it could be accomplished with UDWR staff. The fence, pipeline, and trough are replacing existing structures on previously disturbed areas.
Methods:
The water pipeline will be connected into the current functioning system, cased with drill pipe, and directed to an existing trough by NER Habitat staff. The tire trough will be placed and connected to the water system by NER Habitat staff. Drill pipe fencing and timber harvesting will be contracted out through the state purchasing process.
Timber harvest will be performed in two phases. Phase 1 will consist of the UDWR heavy equipment crew felling and removing 450-500 trees with root wads attached. These trees will be used as material for WRI # 7744 as toe wood for bank stabilization of the Green River in Brown's Park. Phase 2 will go to bid for contracting of approximately 200 acres of clearcutting with a minimal level of disturbance to help promote aspen regeneration and forest stand diversification. All harvested materials will be removed by the contractor in exchange for using a process to create a minimal amount of ground disturbance appropriate for aspen regeneration.
Monitoring:
UDWR staff will establish photo points in the timber harvest area to monitor aspen response. Water system and fencing will be monitored by UDWR staff and a future operator for maintenance needs.
Partners:
WRI project #7744 as mentioned in the "Methods" section
Future Management:
Future project phases on the WMA will be guided by the HMP when it is completed in 2026.
Sustainable Uses of Natural Resources:
Fence maintenance will help control neighboring domestic livestock, protecting the WMA's resources for wildlife use. Future permitted grazing on the WMA will be better controlled and distributed with the fencing and water upgrades.
