“…The inoculation approach is more complex to implement, but there are several possible avenues to consider (Koziol et al ). Some studies have employed topsoil transfers (Bever et al ; Carbajo et al ), but the volume of soil needed would likely be very detrimental to remnant prairies.…”

“…One explanation for relatively low diversity in restorations compared to remnants is the species composition of seed mixes and the density at which seeds are sown (Foster 2001;Polley et al 2005;Dickson & Busby 2009;Barr et al 2017). Restorations also may be limited by abiotic or biotic environmental factors, with the latter including the nature of the soil microbial community composition (Kardol & Wardle 2010;Wubs et al 2016;Koziol et al 2018), as well as interactions with plant species already present at a restoration site (Dickens et al 2016).…”

“…A very different explanation for relatively low plant diversity and richness in restorations is lack of soil biotic components found in remnant prairies. The native prairie soil community is known to be important in maintaining plant diversity in prairies and prairie restorations (Reynolds et al 2003;van Der Heijden et al 2008;Koziol et al 2018). Mycorrhizal fungi, a plant symbiont, have been of particular interest in restoration research because of the benefits of mycorrhizal inoculation to native prairie plants (Smith et al 1998;Middleton et al 2015;Koziol & Bever 2017;Shivega & Aldrich-Wolfe 2017).…”

“…Although increased sowing density and inoculation with a native prairie soil community have each been suggested as best practices for increasing restoration success Rowe 2010;Perring et al 2015;Koziol et al 2018), we do not yet know the relative contributions of these two approaches, or what happens if both strategies are combined. Conceptually, there are at least four possible outcomes (under the assumption that we focus on a single response variable such as richness or diversity, and assume that each strategy alone has a positive effect).…”

Restoration practitioners have a variety of practices to choose from when designing a restoration, and different strategies may address different goals. Knowledge of how to best use multiple strategies could improve restoration outcomes. Here, we examine two commonly suggested strategies in a single tallgrass prairie restoration experiment: increased forb sowing density and prairie soil inoculation. We designed a study with two different forb seeding densities. Within these densities, we transplanted seedlings into 1‐m2 plots that had been grown in either a whole prairie soil inoculum or sterilized prairie soil. After 4 years, we found positive effects of both high forb sowing density and inoculation treatments on the ratio of seeded to nonseeded plant cover in these plots, and negative effects of both treatments on nonseeded plant diversity. No effects of either treatment were seen on seeded plant diversity. Each strategy also affected the plant community in different ways: high forb sowing density increased seeded forb richness and decreased native nonseeded plant cover, while inoculation decreased non‐native cover, and tended to increase average successional stage of the community. These effects on restoration outcome were typically independent of each other, with the result that plots with both manipulations had the most positive effects on restoration outcomes. We thus advocate the combined use of these restoration strategies, and further studies which focus on both seeding and soil community manipulation in restoration.

Soil microbiome mediates positive plant diversity‐productivity relationships in late successional grassland species

et al. 2019

Which processes drive the productivity benefits of biodiversity remain a critical, but unanswered question in ecology. We tested whether the soil microbiome mediates the diversity‐productivity relationships among late successional plant species. We found that productivity increased with plant richness in diverse soil communities, but not with low‐diversity mixtures of arbuscular mycorrhizal fungi or in pasteurised soils. Diversity‐interaction modelling revealed that pairwise interactions among species best explained the positive diversity‐productivity relationships, and that transgressive overyielding resulting from positive complementarity was only observed with the late successional soil microbiome, which was both the most diverse and exhibited the strongest community differentiation among plant species. We found evidence that both dilution/suppression from host‐specific pathogens and microbiome‐mediated resource partitioning contributed to positive diversity‐productivity relationships and overyielding. Our results suggest that re‐establishment of a diverse, late successional soil microbiome may be critical to the restoration of the functional benefits of plant diversity following anthropogenic disturbance.

1. Multiple drivers of environmental change pose a significant challenge for ecological restoration, including climate change, soil salinization and environmental pollution. Due to the important role that soil biota play in enabling plants to cope with a variety of abiotic stressors, there is growing interest in the use of microbial inoculations to facilitate native plant restoration in the face of such change. 2. Recently, novel methods have begun being explored in agriculture to harness stressconditioned soil biota for improving abiotic stress tolerance in crop species. Similar applications in ecological restoration-where plants are inoculated with indigenous soil microbial communities that are preconditioned to various abiotic stressors-could potentially increase our capacity to restore degraded ecosystems under global change. 3. In this paper, we aim to (1) outline the ways in which soil microbial communities might be conditioned in order to confer greater stress tolerance to plants that are targets for restoration; (2) highlight successful (and unsuccessful) examples where stress-tolerant soil microbial communities were utilized to improve plant performance; (3) describe the ways in which stress-conditioned soil biota could be deployed in order to assist ecological restoration; and (4) discuss the potential risks and outstanding questions associated with such an approach. 4. If restoration practitioners are able to harness the soil microbiome to improve plant stress tolerance as is currently being explored in agriculture, this could revolutionize methods for the restoration of degraded lands in the Anthropocene.
