Need for Project
Vegetation restoration and fuel reduction projects have been successful for increasing plant diversity and resilience, however disturbance, whether from fire or mechanical methods, often promotes cheatgrass expansion. The purpose of this project is to control cheatgrass in by using pre-emergent herbicides which are effective at preventing cheatgrass seed germination and growth.
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
The objective is to aerially apply pre-emergent cheatgrass herbicide in late winter or early spring (previous to germination) over 11 thousand acres. The goal is to reduce cheatgrass expansion and give native forbs, grassed and brush improved environmental conditions for growth, diversity and fire resilience.
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?)
Cheatgrass continues to invade newly disturbed or treated areas, reducing potential for vegetative diversity and success. If not specifically targeted, cheatgrass may eventually dominate the landscape and propagate a seed source that furthers invasion into native vegetation and adjacent areas. Cheatgrass monocultures burn frequently and newly burned areas typically convert from some native vegetation to pure cheatgrass monocultures. Cheatgrass monocultures decrease forage for wildlife grazing and restrict vegetative diversity. There is a risk that, once the area is re-burned and seeded, poor moisture regimes could result in seed crop failure and cheat grass re-sprouting. Using the herbicide Plateau will reduce this risk for several years, but if failure occurred the area may need to be re-sprayed, re-burned and/or re-seeded. As areas convert to cheatgrass it reduces the amount of small rodents in the area. Kit fox then have to go longer distances to find prey species. Without this project there will be a diminished habitat for kit fox.
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.

Fire/Fuels
In rangeland, the most profound impact of cheatgrass is its influence on fire regimes. Cheatgrass increases the continuity of fine-textured fuel which promotes larger and more frequent fires. Because the fire return interval is shortened, perennial vegetation is unable to completely recover before the next fire. At the same time, cheatgrass continues to increase, promoting larger and more frequent fires. Perennial vegetation is eventually removed from the system, resulting in a near monoculture of cheatgrass (MT200811AG Revised 6/12). Wildfire in 1994 and 2005 have resulted in a dense cheatgrass mono-culture which dominates this area. The loss of sagebrush and other native vegetation combined with the invasion of cheatgrass into the burned area has altered the ecosystem integrity and productivity. The project intends to reduce unnatural increases in wildfire frequency in project areas and in adjacent sagebrush communities. Additionally, by treating the area with Imazapic (Plateau) herbicide prior to seeding this project should reduce the amount of flammable cheat grass in the area. Without treatment, the area is considered to be at a very high risk of more frequent and intense wildland fires. Reducing the fire risk in the Phase 3 treatment area would reduce fire risk in Phase I and Phase II treatment areas and adjacent sagebrush areas. These areas offer crucial antelope habitat, potential pronghorn fawning grounds, critical winter habitat for mule deer and year-long habitat for elk. The area also supports habitats for ferruginous hawk, white-tailed prairie dogs and kit fox and forging areas for eagles and various other raptor and migratory bird species.
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
In addition to reducing cheatgrass cover and creating vegetative diversity, this project will create structural diversity on this landscape. Sagebrush plants are good at catching drifting snow and holding that snow longer into the spring. This could result in more available moisture for other plants. Cheatgrass, as a winter annual, gains a competitive advantage over native and rangeland species that may not grow very much through the fall and winter and do not begin growth as early in the spring. Soil water depletion is one of the primary mechanisms by which cheatgrass competes with vegetation. This is especially problematic when attempting to revegetate land infested with cheatgrass. As spring precipitation diminishes and summer temperatures rise, perennial grass seedlings may not be big enough to survive, while cheatgrass plants are already producing seed to continue the next generation (MT200811AG Revised 6/12).
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.

Monitoring
Monitoring will consist of randomly located vegetation transects with the purpose of measuring both over-story and under-story vegetation change. Measurements will include line-point intercept cover, tree density, species richness, and seeded species frequency using BLM's Assessment, Inventory, and Monitoring (AIM) protocols. Repeat photographs will also be taken.

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
The goal is knock back cheatgrass infestation with one application of pre-emergent herbicide which has be shown to decrease germination for two growth cycles. After two seasons the areas will be assessed to validate if additional or more aggressive applications are needed.
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
although this may affect grazing in the short term. It will hopefully lead to better forage in the long term.
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.
