Project Need
Need For Project:
Historically, Green, Providence and Logan Dry Canyons wintered large numbers of mule deer. The number of mule deer wintering within sagebrush and bitter brush that grow on the foothills of these canyons have declined for at least two decades (UDWR Northern Region Range Trend Studies in1984-2011) indicating that these habitats are not in properly functioning condition. The cause of these declines are a combination of droughts, fires, encroachment by juniper, and competition from non-native grass species such as cheat grass, intermediate wheat grass and smooth brome. The 2006 Northern Region Range trend Studies publication states "herbaceous understory's are dominated by annual grasses and weedy forbs. Recruitment from young sagebrush and other shrubs has been minimal the last 3 readings (taken every 4 years) and the competitive understory may be limiting them from replenishing the population." In the Cache Unit Area, which includes the Logan Ranger District, "The browse trends for the mountain big sagebrush studies have steadily been declining since 1996. Only 6 out of 17 studies in 2006 had young shrubs to replace old, dying plants in the population." Range trend surveys were read again in 2011 and 2016, and a similar trend continued. Because of the lack of recruitment, sage brush and bitterbrush, as well as key forage species for wintering big game the average number or shrubs per acre has declined.
Winter habitats along the south-facing slopes of Green, Providence and Logan Dry Canyons are crucial habitat for the survival of wintering big game on the Logan Ranger District. While summer forage appears abundant at higher elevations, wintering animals congregate in limited areas in winter time because of the snow and cold temperatures. Winter survival of deer in these areas depends on the quality and quantity of forage on winter ranges. Since deer and elk eat mostly shrubs during the winter, shrubs are a crucial component of their winter habitat. Declines in shrub density have caused high losses of deer and in particular, fawns, in this area.
Objectives:
The project proposes Juniper removals in Green, Providence and Logan Dry Canyons. The project areas are approximately 287 acres in Green Canyon, 50 acres in Providence Canyon and 44 acres in Logan Dry Canyon. In areas of high juniper densities, competition from juniper trees would be reduced through hand cutting. The cut Junipers would be either "cut and removed", "cut piled and burned" or "lopped and scattered". We would remove between 50 -100 percent of the juniper in targeted areas to create a mosaic of areas with junipers and open areas. To restore browse species in the area Mountain Big Sage (Artemesia tridentate vaseyana ), Antelope Bitterbrush (Purshia tridentata) and snowberries would be planted or seeded. These treatments would be conducted in the late summer, fall or winter to improve success and avoid impacts to migratory birds. The project does not include wilderness. Implementation may begin in Fall of 2018.
Project Location/Timing Justification (Why Here? Why Now?):
Threats to this area from juniper invasion are a loss of crucial winter habitats for Mule Deer and Elk. Losing this habitat component would render this area ineffective as winter habitat for deer and elk and summer and transitional habitat for deer. Action taken now would help to maintain these habitats against this threat.
Relation To Management Plan:
The project is consistent with the following plans, as well as goals and objectives:
Forest Plan of the Uinta-Wasatch-Cache National Forest
Forest wide Goals: 3-Biodiversity & Viability, Goal 3d, Goal 3f., Goal 3g. Goal 3o.,
The project is consistent with the following Forest Plan Objective:

DEER HERD UNIT MANAGEMENT PLAN, Deer Herd Unit # 2 (Cache)
Meets habitat goals and objectives for this plan. * Logan, Green, Providence and Blacksmith Fork Canyons. Projects should be focused on removal of encroaching juniper, and reestablishing understory with winter browse species as well as species of plants that can be used in the spring by wintering deer.
ELK HERD UNIT MANAGEMENT PLAN Elk Herd Unit # 2 Cache:
Habitat objective: Maintain and/or enhance forage production through direct range improvements throughout the unit on winter range to achieve population management objectives. Pay special attention to WMA's and areas were holding elk could alleviate pressure on private landowners experiencing damage by wintering elk.Work with private and federal agencies to maintain and protect critical and existing winter range from future losses.
Fire / Fuels:
One of the major threats to sagebrush habitat is fire. This project will help protect and preserve sagebrush habitat by decreasing both fuel loading and fire potential. Removing the juniper will help improve the understory condition and bring the vegetation back to where it should be.
Water Quality/Quantity:
Juniper removal can increase water availability to understory species. Juniper are prolific water users and they outcompete understory species which eventually die off. Because of the water and nutrients made available to other species once Junipers are gone, removing juniper is critical for restoring hydrologic function and ecosystem resilience.
Compliance:
Archaeology surveys were done for potential areas for pile burn. A categorical exclusion was used for this project and NEPA will be completed in a few months.
Methods:
Hand crews would lop and scatter or lop and pile junipers within the project area. Up to 100% Junipers will be removed. Junipers would be cut down below 6 inches to reduce visual effects. In dense areas, Junipers will be piled and burned. Logan ranger District will issue permits to collect fire wood in the cut area to reduce fuel in the area. Also, working with Darren McAvoy with USU to experiment Biochar to reduce fuel in the area. . To restore browse species in the area Mountain Big Sage (Artemesia tridentate vaseyana ), Antelope Bitterbrush (Purshia tridentata) and snowberries would be planted by volunteers. Grass and forbs will be seeded where pile burns occur in FY 2020.
Monitoring:
Vegetation monitoring will include photo points.
Focus Species monitoring will continue.
Range studies will be continued.
There will be follow up surveys in the next three years to ensure no young juniper trees were missed and actions take to remove missed trees.
Partners:
This project is supported by UDWR and also by grazing permitees.
City of Logan and City of Providence.
Utah State University-Dr. Darren McAvoy
Future Management:
Future management includes monitoring sites by visual inspection and photo points. In the long term, the project area will be maintained by slashing young junipers within the project area. Pile burn and seeding will occur later. May plant more shrubs if needed.
Sustainable Uses of Natural Resources:
Green Canyon is within Cottonwood Sheep allotment. Providence Canyon is within the Providence Allotment. Domestic livestock will benefit from improved understory conditions.
