Need for Project
Isolated seral aspen stands are at risk of being lost due to conifer encroachment and lack of disturbance. Aspen woodlands in Utah are crucial habitat for wildlife but are being lost to encroaching conifer. Once established, conifers limit understory diversity and production, eventually shade out mature aspen trees and severely limit the possibility of regeneration. If conifers are not removed by natural fire, disease, or insect events, then aspen stands are at risk of being lost. Although conifer encroachment into aspen is a natural process, it is occurring on a massive scale due mainly to fire suppression. We propose removing the encroaching conifer in isolated aspen stands within the East Tintic and Onaqui Mountains using a combination of cutting followed by burning to promote aspen regeneration and improve understory vegetation condition.
Provide evidence about the nature of the problem and the need to address it. Identify the significance of the problem using a variety of data sources. For example, if a habitat restoration project is being proposed to benefit greater sage-grouse, describe the existing plant community characteristics that limit habitat value for greater sage-grouse and identify the changes needed for habitat improvement.

Objectives
1) Prevent further aspen decline and promote the regeneration and expansion of aspen stands within the East Tintic and Onaqui Mountains. 2) Stimulate aspen regeneration by removing encroaching conifers through cutting and burning. Selective aspen cutting may also occur to stimulate suckering. 3) Increase aspen shoot density post-treatment to a minimum of 1000 stems/acre over a 5 year period, and to protect aspen suckers as necessary utilizing natural barriers or fencing. 4) Conserve and protect watersheds by reducing fuel loading and promoting resilient landscapes. 5) Enhance habitat for avian and terrestrial wildlife. Improve crucial spring/fall and summer mule deer habitat by promoting healthy, diverse understory vegetation.
Provide an overall goal for the project and then provide clear, specific and measurable objectives (outcomes) to be accomplished by the proposed actions. If possible, tie to one or more of the public benefits UWRI is providing.

Project Location/Timing Justification (Why Here? Why Now?)
Aspen is among the most biodiverse vegetation types in the Intermountain West stands and can play a disproportionate role in ecosystems relative to the amount of land occupied. Isolated seral aspen stands in the East Tintic and Onaqui Mountains are dying due to conifer encroachment. Without disturbance they risk being lost. Conifer encroachment into aspen stands results in increased competition for light and resources. Aspen are shade intolerant and require periodic disturbance to stimulate suckering, remove competition from conifer, and maintain open canopy conditions. As aspen habitat age and are encroached by conifer, ecosystem function and wildlife habitat quality decreases. The aspen stands within the East Tintic and Onaqui mountains are small, remote, and isolated, and can provide highly valuable habitat to avian and terrestrial wildlife. Conifer encroachment into aspen stands also reduces the light and space available for a healthy understory, reducing the amount and quality of grass and forb species available for forage. By opening up stands, more area is realized for grass, forb, palatable brush and aspen shoots, increasing carrying capacity for ungulates and other wildlife species. Additionally, increased fuel loading within the aspen stands due to conifer encroachment, increases the likelihood of higher-severity wildfire and reduces the capacity for healthy aspen stands to act as a natural fire barrier. Without treatment these stands will continue to decline eventually resulting in the loss of the aspen resource within these watersheds.
LOCATION: Justify the proposed location of this project over other areas, include publicly scrutinized planning/recovery documents that list this area as a priority, remote sensing modeling that show this area is a good candidate for restoration, wildlife migration information and other data that help justify this project's location.
TIMING: Justify why this project should be implemented at this time. For example, Is the project area at risk of crossing an ecological or other threshold wherein future restoration would become more difficult, cost prohibitive, or even impossible.

Relation to Management Plans
BLM WDD Management Plans 1) Pony Express Resource Management Plan (BLM 1990), as amended: a) Wildlife and Fisheries: Decision 4 (protect habitat values), Decision 5 (improve crucial habitats), Decision 10 (upland game birds). b) Fire Management: Decision 1 (fire suppression). c) Range: Decision 1 (forage use). 2) Salt Lake District Proposed Fire Management Plan Amendment (BLM 1998): a) The FMP specifically mentions the reintroduction of fire into the ecosystem to meet desired resource management objectives (p. 7).'Vegetation management would include a wide variety of management activities including prescribed fire, mechanical manipulation, seeding to a less flammable and more desired species, fuel break establishment, and other strategies (p. 8).' 3) Rangeland Health Standards and Guidelines for Healthy Rangelands. BLM Utah State Office (1997). Standard 3: a) Desired species...are maintained at a level appropriate for the site and species involved. As indicated by: frequency, diversity, density, age classes, and productivity of desired native species necessary to ensure reproductive capability and survival. 4) Utah Wildlife Action Plan. DWR Publication Number 15-14, State of Utah, Department of Natural Resources, Division of Wildlife Resources, Effective 2015-2025: a) The proposed action supports mitigating threats to Aspen-Conifer including: i) Increasing disturbance from either prescribed or natural fire. Recent studies have shown that larger scale burns (e.g., 5,000 acres) that burn more intensely have been the most successful in terms of aspen regeneration. Higher-intensity burns stimulate higher numbers of young aspen per unit area, than lower-intensity burns. A larger treatment area distributes ungulate browse pressure, allowing most young aspen stems to reach a safe height. ii) Applying mechanical disturbance agents such as timber harvest. This can also be used to stimulate aspen regeneration and avoid or reduce resource losses to conifer beetles. As with fire, larger mechanical treatment areas serve to distribute browsing pressure and reduce damage to individual stems, increasing regeneration success. iii) Monitoring smaller, naturally-occurring or human-created disturbances for ungulate damage, and taking follow-up actions such as fencing, hazing, hunting, and/or domestic grazing management, may be required to prevent or reduce damage caused by domestic, wild, or feral ungulates. 5) Utah Mule Deer Statewide Management Plan. Utah Division of Wildlife Resources: a) Section IV Statewide Management Goals and Objectives. This proposal will address Habitat Objective 2: Improve the quality and quantity of vegetation for mule deer on a minimum of 500,000 acres of crucial range by 2019 (see pages 19 and 20). i) Strategy B: Work with land management agencies, conservation organizations, private landowners, and local leaders through the regional Watershed Restoration Initiative working groups to identify and prioritize mule deer habitats that are in need of enhancement or restoration. ii) Strategy D: Initiate broad scale vegetative treatment projects to improve mule deer habitat with emphasis on drought or fire damaged sagebrush winter ranges, ranges that have been taken over by invasive annual grass species, and ranges being diminished by encroachment of conifers into sagebrush or aspen habitats, ensuring that seed mixes contain sufficient forbs and browse species. iii) Strategy F: Encourage land managers to manage portions of pinion-juniper woodlands and aspen/conifer forests in early successional stages. 6) Utah County Coordinated Resources Management Plan: a) Fire Management i) 4. Policies (1) B. Wildland fire should be utilized to protect, maintain, and enhance resources and, when possible, will be allowed to function in its natural ecological role. ii) 5.

Fire/Fuels
The project is being planned to effectively restore resilient, fire-adapted aspen ecosystems across landscapes where aspen is declining. Treatments will move the stands toward properly functioning condition in terms of composition (species diversity) and density (crown spacing and fuel loading). In addition, the treatments will improve structural diversity, promote aspen regeneration and recruitment, increase water retention within the stands, and reduce hazardous fuel loading and fuel continuity in the Onaqui and East Tintic Mountains. Aspen stands create natural fire breaks on the landscape possibly helping to mitigate the risks and damage associated with a high intensity, high severity wildfire.
If applicable, detail how the proposed project will significantly reduce the risk of fuel loading and/or continuity of hazardous fuels including the use of fire-wise species in re-seeding operations. Describe the value of any features being protected by reducing the risk of fire. Values may include; communities at risk, permanent infrastructure, municipal watersheds, campgrounds, critical wildlife habitat, etc. Include the size of the area where fuels are being reduced and the distance from the feature(s) at risk.
*
Water Quality/Quantity
Compared to conifer forests, more snow reaches the ground in aspen stands leading to increased snowpack that lasts longer. By removing conifer and increasing aspen regeneration via prescribed fire and/or mechanical treatments, it is anticipated that watershed resilience, hydrologic storage capacity, and water quantity will be enhanced.
Describe how the project has the potential to improve water quality and/or increase water quantity, both over the short and long term. Address run-off, erosion, soil infiltration, and flooding, if applicable.
*
Compliance
The BLM will complete necessary NEPA, cultural inventories, and wildlife surveys prior to implementation.
Description of efforts, both completed and planned, to bring the proposed action into compliance with any and all cultural resource, NEPA, ESA, etc. requirements. If compliance is not required enter "not applicable" and explain why not it is not required.
*
Methods
The BLM proposed to use mechanical treatments and prescribed fire to meet project objectives. Due to poor road access to the sites (UTV access and foot traffic only) and inability to get fire apparatus near treatment areas, broadcast burning is not practical. Instead hand crews with chainsaws will fell encroaching conifer within and adjacent to targeted aspen stands. Felled conifers would then be piled and burned on-site to stimulate aspen regeneration and reduce fuel loading. Some aspen may also be cut to promote suckering. Where necessary to protect treated stands, some trees may be felled in a manner as to create natural barriers (jackstrawed) to discourage ungulate browsing of aspen shoots. Four-strand and/or 8' tall wildlife fence may also be utilized to protect treated units as necessary. Cutting would occur in summer or fall with pile burning occurring when there is snow on the ground. The majority of the cutting work would be contracted with the BLM doing the pile burning.
Describe the actions, activities, tasks to be implemented as part of the proposed project; how these activities will be carried out, equipment to be used, when, and by whom.
*
Monitoring
Goshawk and other migratory/raptor bird surveys were conducted in 2020. A second year of surveys will be completed in 2021 prior to treatment. Pre-treatment vegetation data will be collected to characterize aspen stand conditions. Data will be collected 1, 3, 5, and 10 years post-treatment to monitor aspen response and to assess if project objectives are met. Data collected will include aspen density transects and photos. Brown's Planar Intercept will be used to determine fuel loading prior to treatment and 1 year following.
Describe plans to monitor for project success and achievement of stated objectives. Include details on type of monitoring (vegetation, wildlife, etc.), schedule, assignments and how the results of these monitoring efforts will be reported and/or uploaded to this project page. If needed, upload detailed plans in the "attachments" section.

Partners
Coordination has occurred with SITLA and they area supportive of the project. Utah Division of Wildlife Resources also supports the work. Private property landowner gave permission to work on their land in the Onaqui Mountains.
List any and all partners (agencies, organizations, NGO's, private landowners) that support the proposal and/or have been contacted and included in the planning and design of the proposed project. Describe efforts to gather input and include these agencies, landowners, permitees, sportsman groups, researchers, etc. that may be interested/affected by the proposed project. Partners do not have to provide funding or in-kind services to a project to be listed.
*
Future Management
Treated areas will be maintained as open aspen stands into the future by removing encroaching conifer. If necessary, fencing will be used to protect regenerating stands. Fences would be removed when aspen reach a minimum of 6' in height.
Detail future methods or techniques (including administrative actions) that will be implemented to help in accomplishing the stated objectives and to insure the long term success/stability of the proposed project. This may include: post-treatment grazing rest and/or management plans/changes, wildlife herd/species management plan changes, ranch plans, conservation easements or other permanent protection plans, resource management plans, forest plans, etc.
*
Sustainable Uses of Natural Resources
Aspen regeneration and removal of encroaching conifers will improve habitat for a variety of wildlife and increase available forage for livestock and wildlife by opening the understory and promoting perennial understory growth. In the absence of treatment, these small, isolated stands will eventually die-off resulting in loss of important habitat. These treatments will promote water and soil retention, and preserve these biodiverse areas for use by wildlife, recreationists, and hunters.
Potential for the proposed action to improve quality or quantity of sustainable uses such as grazing, timber harvest, biomass utilization, recreation, etc. Grazing improvements may include actions to improve forage availability and/or distribution of livestock.
