Journal Article: Cheatgrass die-off as an opportunity for restoration in the Great Basin, USA: Will local or nonlocal commercial native plants succeed where exotic invaders fail? Bromus tectorum (cheatgrass) has widely invaded the Great Basin, U.S.A. The sporadic natural phenomenon of complete stand failure (‘die- off’) of this invader may present opportunities to restore native plants. A recent die-off in Nevada was precision-planted with seeds of the native grasses Poa secunda (Sandberg bluegrass) and Elymus elymoides (bottlebrush squirreltail), of both local and nonlocal origin, to ask: 1) Can native species be restored in recent B. tectorum die-offs? And 2) Do local and nonlocal seeds differ in performance? Additionally, we asked how litter removal and water addition affected responses. Although emergence and growth of native seeds was lower in die-off than control plots early in year...

We designed a study to determine if the temporary lack of cheatgrass caused by die-offs is a restoration opportunity. We seeded native perennial species at three die-offs in the Winnemucca, Nevada area. Native grass establishment in die-offs was almost three times higher in the first season at all sites, relative to adjacent areas without die-off. In the second season, establishment was five times higher in the die-off at two sites, and plants were notably larger in the die-off at the third...

It has focused on conservation of ecosystem function through reducing soil erosion and spread of invasive plants. Effectiveness of mitigation treatments has been debated recently. We searched for literature on postfire seeding of rangelands worldwide. Literature databases searched included SCOPUS, Dissertation Abstracts, Forest Science, Tree search, Web of Science, Google Scholar, and science.gov. Search terms within publications included fire or wildfire in combination with seeding, rehabilitation, restoration, revegetation, stabilization, chaining, disking, drilling, invasives,...

Episodic regeneration failure (“die-off”) has been observed in cheatgrass monocultures and can have negative ecosystem consequences, but can also provide an opportunity for restoration of native species and ecological function within the imperiled sagebrush steppe ecosystem. Proximate causes of cheatgrass die-off are uncertain, although several taxa of fungal soil pathogens have been implicated. Die-off occurrence is stochastic and can occur in remote areas. Thus, developing remote sensing indicators that are repeatable...

Preliminary and published insights on climate responses of sagebrush and implications for vulnerability assessments and post-fire restoration were described. Responses of big sagebrush and competitors such as cheatgrass to climate manipulations are providing important insight on the ways in which sagebrush may resist or respond to warming or shifts in precipitation. Big sagebrush is a remarkably diverse species, and preliminary findings from common-garden studies are suggesting how the diversity is important for its climate responses and for selection of appropriate seed sources....

Seeding effectiveness is typically monitored for three years following treatment, after which a closeout report is prepared. We evaluated 220 third-year closeout reports describing 214 aerial and 113 drill seedings implemented after wildfires from 2001 through 2006. Each treatment was assigned a qualitative success rating of good, fair, poor, or failure based on information in the reports. Seeding success varied by both treatment (aerial or drill) and year. Aerial seedings were rated 13.6% good, 18.3%...
