“…Our results were consistent with another study in western North America that isolated the effects of wildfire from those of livestock grazing (Condon et al, 2018a). Although we focused on direct and indirect effects of wildfires on biocrusts, it is also possible that biocrusts negatively affect wildfires by providing fuel breaks (Condon et al, 2023), creating the possibility for a feedback loop. Other surface disturbances such as rodent digging and vehicular traffic may also have reduced biocrust abundance (Ponzetti et al, 2007; Zaady et al, 2016) but were not systematically measured in our study area.…”

“…fc Wildfire may directly decrease lichen and moss biocrust abundance due to heat exposure or direct combustion in the presence of grazing (Root et al, 2017). However, in the absence of grazing, a negative relationship may be present for moss but not for lichens (Condon and Gray, 2020;Condon et al, 2023). A meta-analysis suggests that neutral and even positive effects of wildfire on biocrusts communities are also possible (Palmer et al, 2020).…”

“…Threats of exotic annual grasses and subsequent changes to the wildfire regime, are placing iconic wildlife species such as the greater sage‐grouse ( Centrocercus urophasianus ) at risk (Coates et al 2016; O'Neil et al 2020). Where wildfire is the sole disturbance, which is an extremely rare condition in the Great Basin, biocrusts, especially the lichen component, remain intact following fire (Condon et al 2023). The persistence of biocrusts after wildfire is important to consider if maintaining low cover of cheatgrass is a management goal, because where cover of biocrusts is greater, cover of annual invasive grasses is lower (Daubenmire 1970; West 1990; Ponzetti et al 2007; Condon & Pyke 2018 a , 2018 b ).…”
