Project Need
Need For Project:
49 acres will be masticated and seeded with an high elevation pollinator mix to increase flowering plant species, and increase forbs for wildlife and stabilize soils.
Objectives:
1. Decrease the probability of a wildfire near Kolob Reservoir which serves as water storage for Washington County (Washington County is the fifth largest county in Utah, and St George is the 8th fastest growing city in the USA, just saying).
2. Increase amount of flowing plants by 10%.
3. Protect and enhance habitat for non-game species including California Condor by creating open space and helping make ranching profitable to avoid subdivision of the land.
Project Location/Timing Justification (Why Here? Why Now?):
1. Fire Risk Management
Fire is a significant threat in this area due to the dense stands of sub alpine fire, with considerable amounts of dead standing and down material. Left untreated, the area is primed for a large, intense wildfire. Continuing to implement treatments will mitigate this threat. High-intensity fires would not only impact wildlife but also threaten older-age ponderosa pine forests and private structures. With the current fuel loads and the extensive fuel buildup across the Virgin River and Kolob drainage and neighboring areas, a wildfire could quickly escalate into a catastrophic event, endangering private homes, the livestock industry in southwest Utah, and watersheds like the Virgin River. This fire would have long-term negative effects on wildlife and fish populations that depend on clean water and healthy riparian areas.
3. Erosion Control and Soil Health
Sheet and rill erosion are contributing to sedimentation from late-phase II pinyon-juniper sites, which lack adequate understory. By applying mastication treatments, mulch will cover the bare soil while seeds are being established. This process will reduce soil erosion, limit moisture loss, and increase the soil's moisture retention capacity. Early results from treatment areas where seeds have been successfully established show promising improvements in soil health and vegetation growth (see photos for details).
4. Vegetational Diversity and Ecosystem Resilience
This project aims to enhance and maintain a diverse suite of vegetational communities. A healthy landscape supports a variety of vegetational states within an ecological site, which benefits a broad range of wildlife species and human activities. Diverse landscapes are also more resistant and resilient to disturbances. Allowing the landscape to transition further into dominant PJ woodlands would reduce its resilience, making it harder for the ecosystem to recover from disturbances. This project aims to reverse that trend by promoting habitat diversity and ecosystem health.
5. Benefits to Mule Deer and Elk
This project will have both direct and indirect positive impacts on high-interest game species, particularly mule deer and elk. Mule deer frequently use this area as a staging ground during migration, helping them enter winter range in better condition. This project will allow mule deer to spend less time on sensitive winter ranges. Elk also use this area from fall to spring unless weather forces them to lower elevations. According to consultations with wildlife biologists, having these animals remain in the treatment area longer is beneficial, as it provides an opportunity for better management compared to when they move into Zion National Park, where management is more difficult. The area's importance to big game populations is critical to maintaining sustainable wildlife populations.
6. California Condor Habitat Enhancement
The California Condor, a species of greatest resource concern, has been documented in the area, particularly around Kolob Reservoir (15 miles west). The open space created by this project will increase the visibility of condors as they search for carrion. The expected increase in herbivore use will likely result in more carcasses being available to condors. According to Hawk Watch, which monitors condor populations in Zion, any improvements for ungulates will also benefit condors. By improving habitat for these large herbivores, this project will contribute to the recovery of condor populations.
7. Importance of Mesic Lands for Wildlife
Private mesic lands and surrounding rangelands play a crucial role in the health of wildlife populations. Research indicates that 60-80% of wildlife depend on mesic habitats, such as wetlands and riparian areas (Thomas et al. 1979, Patten 1998, Belsky et al. 1999, Peck and Lovvorn 2001). Sustainable wildlife conservation cannot be achieved without engaging private landowners. This project, which works directly with private landowners, is vital for the long-term health of local wildlife populations.
8. Critical Migration Corridor and Bird Habitat
This area has been identified as a critical migration corridor for mule deer, underscoring the importance of this project in maintaining habitat integrity. Additionally, the project falls within an identified Bird Habitat Conservation Area (BHCA) focused on riparian habitats, which are essential for bird species like Abert's Towhee, Lucy's Warbler, Bell's Vireo, Gray Vireo, and various waterfowl species. By improving upland conditions, this project will benefit lowland riparian habitats and provide critical resources for these bird species.
9. Native Fish Conservation
Native fish in the Virgin River, including the Virgin Spinedace (Lepidomeda mollispinis mollispinis), Desert Sucker (Catostomus clarkii), Speckled Dace (Rhinichthys osculus), and Flannelmouth Sucker (Catostomus latipinnis), are of special concern. The Virgin Spinedace and Flannelmouth Sucker are both significantly reduced from their original habitats and are managed under conservation agreements. Improvements in water quality and riparian vegetation will benefit these species both on-site and downstream. Protecting these fish species from extinction is critical, especially for those already listed under the ESA and those at risk of listing.
10. Development Threats and Landowner Sustainability
Development pressures in this area are at an all-time high, which poses a threat to the ecology of the watershed. If landowners cannot remain profitable through sustainable land use, they may be forced to sell their property for development, further increasing the risk of recreational development in sensitive areas. Supporting landowners in maintaining profitable and sustainable operations is essential for preserving the landscape and its ecological health.

By reducing wildfire severity and promoting habitat health, it will benefit both human communities and wildlife populations in the area, ensuring the long-term resilience of both natural and managed landscapes.
Water Quality/Quantity:
Hydrological Benefits
Increased Stream Flows: Reducing pinyon and juniper trees will lead to increased and prolonged stream flows. As these trees consume large amounts of water, their removal will allow more water to remain in the system, ultimately benefiting the local watershed.
Soil Moisture and Spring Flow: Several studies highlight the positive effects of pinyon/juniper removal on water retention.
Kormas et al. (study on drainage areas) found that juniper-dominated catchments lose more water to evapotranspiration and experience earlier snowmelt, whereas sagebrush steppe vegetation retains water more effectively.
Deboodt et al. (2008) showed that juniper trees can use up to 30 gallons of water per day, and by removing junipers, late-season spring flow increased by 225%, groundwater levels were higher, and soil moisture availability increased by an average of 41 days.
Baker et al. (1984) found a 157% increase in stream flow following pinyon/juniper treatment over 147 hectares.
Roundy et al. (2014) observed that mechanical treatments to remove pinyon and juniper extended the time that soil water remained available, with up to 18 additional days of soil moisture availability.
Snowpack and Moisture Retention: Research by Roth et al. (2017) indicates that the snowpack is deeper and lasts longer in open areas compared to areas with dense juniper coverage. In low and mid-elevation sites, snow remained for 4-26 days longer, improving the water availability later into the season.
Soil and Vegetation Benefits: Young et al. (2013) also found that removing juniper trees improved soil moisture availability and encouraged more favorable soil climates for desired vegetation, ultimately leading to better water retention.
Water Quality Improvement
Erosion Control and Reduced Sedimentation: The reduction of pinyon and juniper trees, followed by mulching and seed establishment, will stabilize the soil and reduce erosion. This will result in fewer sediments flowing into the North Fork Virgin River, improving water quality.
Reduction in E. coli Levels: By removing livestock from riparian areas and providing alternative forage sources in upland areas, the project will help reduce livestock-related contamination of the water, especially in terms of E. coli. The data gathered during the two growing seasons when livestock are excluded will help identify the specific sources of E. coli, improving future management and mitigation strategies.
Improved Infiltration and Water Quality: Numerous studies show that increasing soil infiltration rates and reducing overland flow enhances both water quantity and quality. This project will likely see similar improvements in soil water infiltration, reducing the likelihood of sediment and contaminants entering water systems.
Long-Term Ecological and Hydrological Outcomes
Increased Snowpack and Extended Snow Duration: As observed in previous studies, tree removal promotes the accumulation and retention of snow, which gradually melts, providing a more stable source of water during the growing season. This results in improved water availability during the late spring and summer months when water is most needed.
Enhanced Vegetation Growth: With the reduction in pinyon/juniper encroachment, native grasses, shrubs, and other beneficial vegetation will have a better opportunity to grow. These plants help to retain soil moisture, increase groundwater recharge, and further improve the water cycle by limiting evaporation and promoting water infiltration.
Conclusion
By reducing pinyon/juniper cover in this area, the project is expected to yield substantial hydrological and water quality improvements. These outcomes include enhanced stream flows, increased soil moisture retention, prolonged snowpack, and reduced erosion and sedimentation. Based on existing research, these benefits are anticipated to have lasting positive effects on the local watershed, wildlife habitats, and overall ecosystem health.
