“…For instance, degraded mine sites or former agricultural fields whose altered substrate requires modification of the target reference model. In these cases, ecosystem damage may be so extensive that recreated habitats are essentially new ecosystems, progressing along novel successional pathways and may exhibit novel characteristics, with target conditions falling outside of the variation observed in native and (or) nearby reference habitats (Hawkes and Gerwing 2019;Nelson et al 2021). If this is the case, we classify these projects as follows:…”

“…We have left the comparative mechanisms between targeted and reference conditions vague. For instance, qualitative examination of conditions could be used (Nelson et al 2021) or more complicated experimental and modeling techniques could be implemented, such as before-after controlimpact designs (Underwood 2009) or multivariate similarity analyses . We argue that the method of contrast does not matter, and the important distinction is the goal of the project.…”

“…A project at one level of the continuum may overlap with the next, especially if changes cascade throughout the target ecosystem. For instance, an Intra-Ecosystem Restoration project may attempt to restore a freshwater lake for endangered frogs by removing invasive fish (Pope 2008;Nelson et al 2021). A related but more ambitious project could aim to have positive outcomes on natural lake processes as well as benefit all trophic levels of the aquatic food web by removing invasive fish (Rewilding).…”

Speaking the same language: Aligning project designations to clarify communication in restoration ecology

As we enter the United Nations Decade of Ecosystem Restoration, the need to engage in restoration activities has never been greater. Included within this need is a requirement for clear communication between researchers, practitioners, policymakers, stakeholders, and community members. To facilitate the discussion and assessment of restorative activities, we propose two decision trees to differentiate between key restoration terms (Reclamation, Rehabilitation, Ecological Restoration, Rewilding, Landscape Restoration, Intra-Ecosystem Restoration, Reference Condition Restoration, and Ecological Reclamation) and to clarify how they relate to each other, based upon project scope and desired/intended project outcomes. Continued use of unclear terminology impedes practitioners or researchers from using the literature efficiently, to find precedents that could assist their current efforts. As such, increasing clarity of communications will ensure restoration is discussed within a framework of well-defined and agreed upon terms. It is our hope that this suggested framework will contribute to the ongoing and much needed terminology debate and help enhance cohesion on the use of key terms within the restoration focused literature. Given the increased focus upon restoration projects of any kind, especially during the UN's decade of ecosystem restoration, it is more important than ever that restoration practitioners speak the same language.

“…While trophic and habitat-related abiotic variables are known to influence community structure in many ecosystems, some systems appear to be only minimally influenced by them. For instance, ephemeral freshwater habitats, such as floodplains, can act as resource-pulse ecosystems (Crook et al 2020;Nelson et al 2021). In such systems, amply available resources, whose availability is temporally limited, trigger a cascading response throughout the ecosystem, minimizing the controlling influence of competition for resources, predation, and an individual species' preference for abiotic conditions (Tilman 2004;Letnic and Dickman 2010;Greenville et al 2014).…”

While trophic and habitat-related abiotic variables (predation, competition, tolerance, etc.) are known to influence community structure in many ecosystems, some systems appear to be only minimally influenced by these variables. Sampling multiple tidal flat communities in northern BC, Canada, we investigated the relative importance of top-down and middle-out (mesopredators) variables, competition for resources (bottom up), and abiotic variables in structuring an infaunal community (invertebrates living in sediment). Similar to previous studies on mudflats in the Bay of Fundy (also at a north temperate latitude), we determined that these variables accounted for a minor (0%–9%) proportion of the observed variation in this infaunal community, suggesting that these variables play a small role in structuring this community. Based on the results of our study and in combination with previous experiments on infaunal recovery patterns post disturbance, we posit that the main factors influencing these infaunal communities likely operate at a scale of sites (kilometres) and(or) plot (metres or less) but not transects (10–100 m within site). Candidate forces structuring these intertidal communities that need future examination include regional species pools and the variables that affect these pools, sediment biogeochemistry, and disturbance/recovery history of a site. The similarity of our Pacific coast findings to those from the north temperate Atlantic coast suggests some similarity in the processes structuring these distinct infaunal communities.
