Dark Canyon Plateau has become heavily encroached with pinyon and juniper. Old chainings and prescribed burns that were seeded with crested wheatgrass have begun to fill in and have created closed canopy forests that have reduced ground cover. The plateau is considered critical elk winter range and due to the encroachment and heavy cattle use the risk of large wildland fires has increased along with water erosion and an overall decline in watershed health. The project units are within the Black Steer-Dark Canyon watershed.

1) Restore watershed health and function by reducing pinyon and juniper trees 2) Reducing the risk of large wildland fires 3) Increase sagebrush 4) Improve elk winter range 5) Provide additional and alternative water sources, in form of stock ponds, to livestock and wildlife in order to improve animal distribution and utilization of forage, relieve pressure on existing water sources. Pinyon/juniper forests have historically been controlled by fire frequency (Miller and Wigand 1994), but because of changes in management and use the fire return interval has greatly increased. Lack of natural disturbance along with prolong periods of drought have led to the expansion of pinyon/juniper into areas that were typically shrubland dominant. Common to the hydrology of many of these communities, when trees are dominant they are a relatively high evapotranspiration component of the water budget (Roundy et al. 1999) and high exposure of surface soils between tress that provide of major sources of runoff and erosion. Research has shown that in the southwest much of the erosion in these systems occurs in mid-summer during the monsoons and mid-winter with snow melt (Wilcox 1994). Shallow soils between tree canopy areas are wetter than in areas where canopies receive less precipitation due to interception (Breshears 1993). Pinyon and juniper trees deplete soil moisture in intercanopy areas as they transpire more in the winter. The lack of water and nutrient availability from tree-root exploitation of interspaces can result in eventual mortality of understory vegetation in absence of fire of other tree killing disturbances (Breshears et al 1997). Manipulating vegetation that is deep rooted and uses more water (ie pinyon and juniper) allows more water to percolate through the soil and enter ground water and streams (Hibbert 1983). Additionally, removing the trees opens they interspaces and allows for more water availability to other vegetative species that would typically dominate the site. Because much of the work is associated with old chainings there will be almost 100% removal of pinyon and juniper trees from the site. Through monitoring our objects are to see an increase of native plant diversity, at least a 70% change in the species composition and cover and a 50% change in the soil surface gaps, which is an indicator for wind and water erosion risk, water infiltration and the exotic plant invasion risk. We would like to see and increase of 20-25% in shrub cover and 20-30% increase in grasses and forbs."

Continued decline in watershed function associated with pinyon/juniper encroachment and closed canopy forest leading to increased erosion, high fire potential and overall loss of critical habitat. By thinning trees the risk of large fires will decrease, understory vegetation recruitment can occur and there will be an overall improvement in habitat. Phase I of this project have already shown a vast improvement in the overall increase in plant cover and diversity and a decrease in erosion. Improving ponds and water availability to livestock will improve the timing, duration and intensity of livestock grazing and reduce the risk of altering vegetation structure and composition, water quantity and quality, and soil structure and stability. Additionally by improving livestock distribution the risk of reducing water infiltration, increased bare ground and the potential for increased water run-off and soil erosion is greatly reduced.

The plan (Section 4 p.108) supports vegetation treatments, such as mechanical and burning, to restore rangeland for the mutual benefit of livestock and wildlife. Section 5 revision (p. 110) promotes programs to remove pinyon and juniper with mechanical treatments to stimulate grasses and improve water yield. 15) Utah Comprehensive Wildlife Conservation Strategy *Shrubsteppe habitats ranked out as the 4th highest habitat priority for the state of Utah.

The Dark Canyon Plateau area is currently classified as a Condition Class 3 Fire Regime. There is a high departure from the historical regime of the vegetation characteristics and fuel composition on the plateau. Pre treatment monitoring indicates that the pinyon/juniper ranges from a Phase 2 to Phase 3 condition where the percent tree cover ranges from 25-50%, percent shrubs 2-10%, percent grasses is 4-20 and bare ground is 30-65. Historic fire scars within the project area show stand replacing, hot, extreme fire behavior. Cheatgrass and annual weeds are now the dominant species within the burn areas. By reducing that canopy cover and returning the plant community to a more diverse resilient community that includes grasses, forbs, and shrubs, the risk of have a large catastrophic stand replacing fire on the Dark Canyon Plateau would greatly be reduced. This will also protect the existing critical elk and mule deer winter habitat.

The project area is located with the Dark Canyon and Cataract Canyon-Colorado River HUC 12 Units.

Class 3 archaeological surveys have been completed and will continue as each phase develops. SHPO and Native American Consultations have also been completed and will continue as each phase develops. Archaeological surveys, SHPO and Native American Consultation meet the requirements outlined for Section 106 of the National Historic Preservation Act. NEPA was completed in 2012. All methods and phases are compliant with the 2008 Monticello Field Office Resource Management Plan. Section 7 Consultation has been completed in compliance with the Endangered Species Act. NEPA was completed in

Archaeological surveys and raptor surveys will be completed before on the ground work occurs. Two tracked bullhogs will be used to remove pinyon with a dbh of 18 inches or less and juniper with dbh of 22 inches or less. Bulldozers will be used to to improve existing ponds by removing vegetation and sediment. Dams will also be improved and stabilized.

BLM will continue to monitor existing long-term, permanent vegetative studies established in key use areas on the Dark Canyon Plateau. All monitoring activities will involve quantitative and qualitative techniques and be repeated annually for the first five years, then every three years after.

Partners for this project include The Nature Conservancy, DWR, Utah State University, USGS and Canyonlands Research Committee.

Annual grazing management plan will address vegetation/forage conditions and water availability when set setting stocking rate and timing. These additional water sources will allow for more options in the management of livestock on Dark Canyon Plateau these include timing and rate of grazing, rest rotation of pastures, reduction of pressure on springs of Dark Canyon Plateau.

Improved availability of water, facilitation of better livestock grazing management, improved utilization of forage.

Machine mastication, two Barko masticators. All Pinyon trees within the unit boundary up to 18" DRC and all Juniper trees up to 22" DRC were masticated. Trees directly adjacent to deep arroyos and in severely broken country were left uncut. Any dead and down chaining debris was masticated. Any other shrubs or trees encountered were left untouched. Archeological clearance survey was conducted for 1042 acres (affected area in map) for future Phase 5. Three earthen reservoirs where also built, to help disperse livestock use and for the benefit of wildlife. These reservoirs are part of the original planning document.

The Dark Canyon project was designed to remove Pinyon and Juniper encroachment from sage and grass meadows established previously by BLM "seeding" and chaining operations. Older condition class 3 tree stands were converted to condition class 1 or 2 through thinning of smaller size class trees opening up the understory for herbaceous response and slowing erosion of top soil. Erosion was exposing cultural resources and cutting deep arroyos on the plateau. Winter range for wildlife and more opportunity for grazing flexibility to lessen impacts to the Plateau overall will be realized. The likelihood of large stand replacement fire has been reduced while preserving some of the oldest members of the adjacent Pinyon and Juniper forests.

Will Monitor treatment area for herbaceous response. Will determine if follow up seeding or additional grazing modifications are needed to facilitate reset. Will monitor impacts from wildlife and grazing. Phase V will begin in Fall 2018.
