“…Steud., the focal invader of this study, is a perennial rhizomatous grass species with a broad distribution in diverse aquatic habitats (Eller et al, 2017; Saltonstall, 2002). An invasive P. australis lineage, originating in Eurasia, has experienced rapid spread in North American wetlands (Lambertini et al, 2012; Saltonstall, 2002) with deleterious ecological impacts (Meyerson et al, 1999; Pendleton et al, 2020; Wails et al, 2021). Relative to the native subspecies ( americanus ; sensu Saltonstall et al, 2004), the invasive lineage of P. australis (subsp.…”

Sowing native seeds is a common approach to reintroduce native plants to degraded systems. However, this method is often overlooked in wetland restoration despite the immense global loss of diverse native wetland vegetation.Developing guiding principles for seed-based wetland restoration is critical to maximize native plant recovery, particularly in previously invaded wetlands. Doing so requires a comprehensive understanding of how restoration manipulations, and their interactions, influence wetland plant community assembly. With a focus on the invader Phragmites australis, we established a series of mesocosm experiments to assess how native sowing density, invader propagule pressure, abiotic filters (water and nutrients), and native sowing timing (i.e., priority effects) interact to influence plant community cover and biomass in wetland habitats. Increasing the density of native seeds yielded higher native cover and biomass, but P. australis suppression with increasing sowing densities was minimal. Rather, community outcomes were largely driven by invader propagule pressure: P. australis densities of ≤500 seeds/m 2 maintained high native cover and biomass. Low-water conditions increased the susceptibility of P. australis to dominance by native competitors. Early sowing of native seeds showed a large and significant benefit to native cover and biomass, regardless of native sowing density, suggesting that priority effects can be an effective restoration manipulation to enhance native plant establishment. Given the urgent wetland restoration need combined with the limited studies on seed-based wetland restoration, these findings provide guidance on restoration manipulations that are grounded in ecological theory to improve seed-based wetland restoration outcomes.

“…Without extensive field surveying of the site once the development has been completed, it is hard to prove empirically whether the Defra Metric's position on the plan is correct or not, although its divergence from Natural England recommendations (see Supporting Information: Section ) suggest that it does not reflect likely benefits. Furthermore, the results of this study (see Supporting Information: Section ) indicate that the tool is unable to consider either scale or heterogeneity of habitat, both of which are crucial for biodiversity (Báldi, 2008; Benton et al, 2003), ecosystem functioning and/or services, and resilience (Bullock et al, 2022; Pendleton et al, 2020; Waters, 2022).…”

The built environment, even at its ‘greenest’, inevitably entails changing ecosystem structure and function. Multiple sustainable development tools and approaches are available to reduce environmental harm from built development. However, the reality that society exists within fully integrated socio‐ecological systems, wholly interdependent on supporting ecosystems, is not yet adequately represented in regulation or supporting tools. Regenerative development seeks to address this interdependence in part by improving the health of supporting socio‐ecological systems through the development process. We demonstrate the relevance of a series of approaches – Local Nature‐Related Planning Policy (LNRPP), Biodiversity Net Gain (BNG), the Environmental Benefits from Nature Tool (EBN), Nature Assessment Tool for Urban and Rural Environments (NATURE Tool), and RAWES+ (Rapid Assessment of Wetland Ecosystem Services+) – in terms of their ability to meet their stated aims and objectives, and how these relate to wider regenerative themes. A comparative analysis of the five approaches is carried out through their application to a practical case study site, resulting in policy‐ and practice‐relevant learning and recommendations. The research reveals current gaps in methodology, which can lead to adverse outcomes for sustainability. This is particularly clear in relation to the spatial and temporal scales across which each approach operates. In addition, this research discusses the inherent limitations of taking a reductionist approach to examine complex systems.

“…They play a pivotal role in the ecological processes supporting biodiversity and maintaining environmental health because they are highly dynamic ecosystems. Wetlands make up only around 5% of the Earth's surface area, yet they provide over 40% of ecosystem processes and services (Pendleton et al 2020). It is a highly productive ecosystem due to fast recycling and metabolically active aerobic and anaerobic bacteria (Bodelier and Dedysh 2013; Huang et al 2018).…”

Ramsar sites are wetlands of international importance covering major ecosystem processes and services.Bacterial communities play a signi cant role in the lacustrine ecosystem and release major nutrients in wetlands, yet little is known about controls over their distribution and abundance from the Ramsar site of Central Himalayas, Nepal. Thus, we studied the bacterial community composition, diversity, and functions in the wetlands (designed as Ramsar site, Ramsar no 2257) during the autumn and spring by using 16S rRNA gene-based Illumina MiSeq sequencing. We reported a pronounced variation in water physicochemical and biological properties (temperature, pH, Chl a, DOC, and TN), bacterial diversity, and community composition. Alpha diversity was highest in Autumn while beta diversity (based on unifrac distance) in spring. Our results uncovered the effect of nutrients on bacterial abundance, richness, and community composition. Most unique operational taxonomic units (OTUs) (58%) belonged to autumn, while 14% of the OTUs were shared between spring and autumn. Planctomycetes and Bacteroidetes dominated the spring exclusive OTUs; meanwhile, Actinobacteria dominated the autumn exclusive OTUs. Bacteria in these wetlands exhibited divergent roles; however, a higher abundance of bacteria associated with animal parasites and human pathogens indicated a public health risk. By disclosing the seasonal variation of bacterial community and their relationship with environmental factors, this rst-hand work in the Ramsar site of Nepal will develop a baseline dataset for the scienti c community that will assist in understanding the wetlands microbial ecology and biogeography.
