“…In general, diversity metrics do not tend to be reliable indicators of functional differences (Louca et al 2018). For instance, plant invasions often lead to disparate soil microbial community composition (Gornish et al 2016(Gornish et al , 2020McTee et al 2017;Parsons et al 2019), but a recent meta-analysis revealed they generally do not have a signi cant impact on microbial richness (Custer and van Diepen 2020). Additionally, diversity metrics can be obscured due to the persistence of relic DNA from dead microorganisms (Carini et al 2016).…”

Cheatgrass invasion of Intermountain sagebrush steppe in the Western US poses increasing challenges to the function and survival of this native ecosystem. The invasive success and persistence of cheatgrass has been attributed to its physiology, phenology, and recently to increases in soil nitrogen levels. We investigated whether cheatgrass invasion of sagebrush/native bunchgrass communities elevated soil ammonium and nitrate levels, and resulted in soil microbial community diversity and composition changes. Our results did not reveal an increase in nitrogen ions, but showed a shift in soil microbial communities towards bacterial functional groups that can promote nitrogen accumulation in cheatgrass invaded communities.

“…A case in point is buffelgrass (Pennisetum ciliare), one of the most abundant, broadly-ranging, and rapidly-spreading invasive plants in the southwestern United States (Gornish et al, 2020;Marshall et al, 2012). Buffelgrass was introduced to North America from Africa in the 1930s for range management but rapidly invaded large areas of the Sonoran desert grasslands and shrublands, inducing transformative changes to native ecosystems (Gornish et al, 2020;Marshall et al, 2012). The successful dominance of buffelgrass over native species in many areas of the world is attributed to a suite of traits and mechanisms including: high seedling survival rates, an ability to quickly colonize bare soil (McIvor, 2003;, high water-use efficiency (Eilts & Huxman, 2013;Lyons et al, 2013), tolerance to extreme drought (Fensham et al, 2013;Marshall et al, 2012), and allelopathic processes (Cheam, 1984).…”

“…For example, Saguaro cacti (Carnegiea gigantea) populations are at extreme risk from widespread fires in the region. In addition, buffelgrass invasion alongside a positive buffelgrass-fire feedback cycle results in altered ecohydrology and soil microbiomes and increases in buffelgrass dominance, leading to irreversible shifts in vegetation composition and loss of biodiversity (Castellanos et al, 2016;Gornish et al, 2020).…”

1. Buffelgrass (Cenchrus ciliaris syn. Pennisetum ciliare) was introduced to Sonoran Desert in the early 20th century and has become widespread at low elevations. This perennial bunchgrass accumulates abundant biomass that can carry fires through ecosystems not adapted to fire, resulting in devastating impacts for native cacti and other plant and animal life.2. Buffelgrass is most effectively managed through the application of herbicide when the grass is at least 50% green. Because the grass rapidly greens up following summer monsoon rainfall, it is possible to forecast green-up using daily rainfall measurements.3. In 2019, the USA National Phenology Network (USA-NPN) released daily Buffelgrass Green-up Forecast maps for the state of Arizona based on the PRISM 4 km daily total precipitation product. The daily digital Buffelgrass Green-up Forecast maps are a freely available data product and meet the FAIR principles of findability, accessibility, interoperability and reusability. They are permanently archived and publicly accessible as raster and image layers from the USA-NPN website.4. These map layers support planning the timing of management activities to maximize buffelgrass treatment efficacy and researchers seeking to incorporate daily estimates of buffelgrass greenness in their analyses.
