Project Need
Need For Project:
The Flatt Fire started June 18, 2021. This was a fast moving fire that burnt 14,356 acres of PJ, sage brush flats, and cliff rose and bitter brush stands. The monsoons of 2021 were intense in the region and the flooding did occur on the burn scare and in the town of Enterprise. The warm season grasses have started to response as well as the cheat grass.
Planting seed as soon as possible to make sure it is ready for spring green up will curial for the health of the watershed and the supporting wildlife in the area. Mule deer use this area during the breeding season and winter. This is part of the Pine Valley Mule Deer Herd Management Unit. The establish of browse will vital for the deer in this area. Working with the private landowners we hope to reduce the depredation on agriculture lands and establish high quality forage as soon as possible.
Objectives:
Reintroduce perennial grasses, forbs and shrubs and increase frequency to at least 25%.
2. Reintroduce perennial grasses, forbs, and shrubs on mule deer, and other wildlife habitat.
3. Reintroduce perennial grasses, forbs and shrubs to establish and compete with invasive annual grasses.
4. Reduce sedimentation and erosion.
Project Location/Timing Justification (Why Here? Why Now?):
Cheatgrass has infested this area and contributes to an unhealthy fire cycle. The nature of this species is to carpet a landscape with flashy quick burning fuel for wildfires after its short growth cycle in the cool early part of springtime. Cheatgrass when coupled with frequent fires can change an entire ecosystem. The Flatt fire consumed both the tree/shrub canopy and understory vegetation. Soils within the burn are left exposed to wind and water erosion and are now susceptible to further invasion of the spread of cheatgrass and other non-native annual species. The Flatt fire has been classified as "moderately susceptible" to fire damage for the most part indicating that the soil has potential to be damaged by creating a water repellant layer, volatilization of essential soil nutrients, destruction of soil biological activity, and vulnerability to erosion with high severity fires. Based on these findings, past fire history in similar areas, and visits to the burned area, protecting the watershed values and reducing the erosion potential within the affected area would be a priority for the Flatt fire ESR project. Additionally, containment and control of invasive, non-native species, such as cheatgrass, which may exacerbate erosion potential and fire frequency and severity that would further degrade habitat is also a very high priority.
Relation To Management Plan:
This action is consistent with the following land use plans and the Normal Year Fire Management Plan.
-Secretarial Order 3362: Site specific Management Activities to Conserve or Restore Big Game Habitat, November, 2018
-Pine Valley Mule Deer Herd Management Plan
-Pine Valley Pronghorn Herd Management Plan
-Utah Wildlife Action Plan
Fire / Fuels:
Future fires will continue to be more difficult to control and have devastating effects by burning at a higher intensity, which could lead to fires getting larger and burning unburned habitat. Treatments identified within this proposal, including seeding with more fire resistant vegetation and are expected to reduce the overall threat of future wildfires, which could impact unburned areas in the watershed.
Water Quality/Quantity:
Erosion issues have the possibility to affect culinary and irrigation water systems negatively in high precipitation/flow events with the removal of vegetation on thousands of acres the aforementioned cities.
Compliance:
Required Class III cultural surveys will be contracted through the State of Utah and will be competed prior to chaining, and construction of burned/protection fences.
Methods:
The Proposed Action is to implement the Flatt Fire Emergency Stabilization and Rehabilitation Plan (ESR). The evaluation team determined that appropriate measures for this burn would include an aerial application of a desirable seed mixture of perennial plant species across the BLM-managed lands of the fire area, followed by a chaining to incorporate the seed into the soil in areas where topography permits. Also, actions will be taken to prevent the further spread and eradicate noxious or non-native species. There is approximately 102 acres that will be treated this fall with 2.5 oz plateau to reduce the competition of cheat grass.
Seeding and Planting Selected areas are proposed for re-seeding within the fire perimeter. contains the proposed seed mix. Proposed treatments include areal seeding only and aerial seeding followed by chaining. Portions of the Flatt Fire are conducive only to aerial seeding. These areas are characterized by steep slopes and are not suitable for mechanical treatments. Aerial seeding followed by chaining or harrowing is the preferred method of seeding in areas where slopes are appropriate and where residual vegetation allows. Noxious or Non-Native Species Prevention Several mapped polygons of Scotch thistle occur within the fire perimeter. These, along with any other Noxious Weeds encountered during our efforts, would be monitored, and treated as appropriate. Actions, if approved, would begin this fall, and conclude by early winter.
Monitoring:
The Assessment, Inventory and Monitoring program (AIM) will be used to monitor vegetation in this project site. This monitoring program uses standard core indicators and methods to provide a statistically valid sampling design across the landscape. The Cedar City Field office will have a team devoted to AIM monitoring, and although the sample points are random, it is likely that some of these points will fall within the project area. Photo monitoring will also be used. Wildlife monitoring will be done with big game classifications and sage grouse counts in the treatment area, during annual surveys.
Partners:
UDWR-working with land management agencies to ensure that resources are available for restoration and that wildlife needs are met.
CCBLM-ESR planning and cultural resources with UDWR archeologist.
SITLA-Planning and cultural resources
Future Management:
In accordance with the Standards for Rangeland Health, rangelands that have been burned, reseeded, or otherwise treated to alter the vegetation composition would be closed to livestock grazing for a minimum of two complete growing seasons.
Sustainable Uses of Natural Resources:
The areas or pastures burned will need to be rested from grazing for a minimum of two years (growing seasons). In the long term, this project will likely have an overall positive impact on domestic livestock grazing because of added forage value following seeding.
