Interpretive Summary:

Technical Abstract: Historically, wildfires in the northern Great Basin experienced wildfire intervals of every 60-110 years and mostly occurred in the late summer after the perennial grasses had flowered and dried out. The accidental and subsequent invasion of cheatgrass throughout the Intermountain West has significantly increased the chance, rate, spread and season of wildfires. In 2018, more than 435,000 acres burned in the largest wildfire ever recorded in Nevada. These catastrophic wildfires have very negative impacts on grazing and wildlife resources, especially shrub obligate and sensitive species such as sage grouse and mule deer. With each passing wildfire season more and more critical shrub communities are burned and converted to cheatgrass dominance. When cheatgrass moves in, wildfires that destroy shrubs follow. Immediately following the Martin Wildfire, a massive collaborative effort took place between U.S. Government and State Agencies which included the Bureau of Land Management (BLM), USDA-Agricultural Research Service (ARS), and Nevada Department of Wildlife (NDOW), Nevada Gold Mines as well as wildlife and conservation organizations. In the process of applying seeding treatments, the Government experienced a shutdown, temporarily halting the BLM’s efforts, but due to the strong partnership with NDOW and the BLM, NDOW did an excellent job and played a major role in seeing this massive seeding effort through without delay. Of the 435,000 acres that burned, this collaborative effort seeded over 70,000 acres in late 2018 and early 2019 and treated another 65,000 acres with pre-emergent herbicides in 2018 to control cheatgrass and followed up with more seeding applications in 2019. The goal of this restoration/rehabilitation effort was to enhance food and cover resources for wildlife and livestock. Efforts aimed to restore/rehabilitate rangelands to an improved state for wildlife and sustainable grazing practices by establishing a high density of native and introduced perennial grasses to suppress cheatgrass and associated fuels. Cheatgrass dominated habitats were treated with pre-emergent herbicides as an aggressive and effective weed control program followed by the seeding of perennial grasses, shrubs and forbs. There was also a goal to monitor these treated habitats to gauge the success of treatments. A number of seed mixes were aerially applied to more than 57,000 acres which included native and introduced grasses, shrubs and forbs. Aerial seeding is often required due to inaccessible and/or rough terrain not suitable for equipment needed in drill seeding operations. Drill seeding of native and introduced perennial grasses yielded significantly higher results than broadcasting efforts of perennial grasses. Aerial application of Wyoming big sagebrush and western yarrow also yielded excellent results. The results of these efforts are very apparent on the ground as sagebrush seedings are striking and perennial grass seedings are more than 4-fold that of unseeded habitats. One of the most successful attributes of the efforts put forth to restore or rehabilitate rangelands burned in the Martin Fire is partnerships. Partnerships provide an opportunity to combine and stretch resources further than individual efforts. Furthermore, partnerships create a more durable environment and are an important element for successful restoration or rehabilitation of rangelands.
