“…The model was checked for zero-inflation, normality, dispersion, and heteroskedasticity using the R package DHARMa (Hartig 2022), with no evidence of model assumption violations. We evaluated predictor significance with a type II analysis of variance test in the R package car (Fox & Weisberg 2018). While the data were modeled on the log scale, they were backtransformed and presented on the response scale using the function "ggpredict" in the R package ggeffects (Lüdecke 2018).…”

“…Fungicide amendments, specifically, can greatly increase emergence (Hoose et al 2022) by protecting seeds from ubiquitous fungal pathogens that target seeds during the time between fall sowing and spring germination (Gornish et al 2015). However, encrusting seeds with fungicides has only been found to increase emergence in field experiment settings when precipitation is above normal (Hoose et al 2022), and in some cases, fungicides do not improve emergence and establishment (Gornish et al 2015; Fund et al 2019; Hoose et al 2022). Further work is needed to understand the conditions under which fungicide amendments are most likely to improve seedling establishment.…”

Coating seeds with amendments to increase germination, emergence, and establishment is a promising strategy for dryland restoration. Seed coatings containing fungicides offer a potential solution in regions where fungal pathogens cause seed mortality during the winter stratification period between late fall seeding and spring germination. The effectiveness of the fungicide treatment, however, may be dictated by weather and within‐site microenvironment. We tested how fungicide coating influenced seedling emergence of native grasses within sagebrush stands by planting untreated seeds and seeds coated (encrusted) with and without active fungicide ingredients in furrows that extended from the canopy edge of sagebrush plants (Artemisia tridentata ssp. wyomingensis) into the interspace. This was replicated at four sites across the Intermountain West in two successive years. We planted two native grasses, bottlebrush squirreltail (Elymus elymoides) and bluebunch wheatgrass (Pseudoroegneria spicata). Emergence was extremely low in both years, with a complete seeding failure (i.e. zero emergence) at two sites in the first year and three sites in the second year. At one site where emergence was sufficient for statistical analysis: (1) the coating on the fungicide and blank treatments inhibited emergence under anomalously dry conditions and (2) across seed treatments, proximity to a sagebrush canopy slightly increased seedling emergence. The variable emergence patterns across sites and years (i.e. the highest emergence was for the site–year combination with the lowest precipitation) highlight the sensitivity of seeding outcomes to, and dependence of fungicide seed coatings on, site conditions, and the necessity of repeating experiments across different weather years.

“…Naturally complex landscapes typically have suboptimal growing conditions for plants. Chemical applications like soil surfactants (Madsen et al 2012;Madsen et al 2016), physical structures like snow fences (Fund et al 2019), and habitat preparation like mulching and increasing planting surface area (Chambers 2000) help increase soil moisture and seedling survival. Additionally, clustering seeds into a single pellet (agglomerative seeding) can provide seedlings enough force to emerge from underneath soil crusts that harden in dry conditions (Madsen et al 2012).…”

The worldwide decline in bee populations is threatening the delivery of pollination services, thus leading to the development of pollinator restoration strategies. In the United States, one way to protect and restore bee populations is to use seed mixes composed of pollinator-friendly native plants to revegetate federal lands following disturbance. However, we lack information about which native plant species and mixes are best for bees. We assessed the attractiveness and use by bees of 24 native plant species that are standard for revegetation projects (focal plants) on national forest lands in western Montana. Focal plants that had the highest visitation rate, attracted the most bee species, supported specialist bee species, and bloomed for extended periods across the landscape were considered "pollinator-friendly." Our results suggest that Salix bebbiana, Arctostaphylos uva-ursi, Lupinus sericeus, Rosa woodsii, Symphoricarpos albus, Erigeron speciosus, Symphyotrichum foliaceum, and Gaillardia aristata could create a seed mix that is effective for pollinator restoration on public lands. Pollinator-friendliness score cards are provided to allow land managers to select plant species to include in restoration mixes that benefit pollinators. Identifying mixes of pollinator-friendly native plant species that are available for restoration will allow land managers to both revegetate disturbed habitats and restore bee communities on federal lands. The methods developed in this project can be used to design seed mixes for pollinator restoration on other public lands.
