Resist, accept, and direct responses to biological invasions: A social–ecological perspective

Abstract

Rapid transformation of the Earth's social and ecological systems has led to a call for new frameworks for addressing change

Case study: Applying the resist–accept–direct framework to an Ojibwe Tribe's relationship with the natural world

“…For example, considerable effort is currently expended to chemically and mechanically reduce the amount of aquatic vegetation (targeting non‐native Eurasian watermilfoil) in the Minocqua Chain (Hatleli, 2019), with the hope of favouring ogaa habitat and reproduction. Instead, the Partners could decide to accept changes in the ecosystem (in this example, no aquatic plant management—see Dunham et al (2022) on applying the RAD framework to biological invasions), which would limit the input of herbicides and other chemicals into the chain, thereby minimising some negative effects on the ecosystem (Dehnert et al, 2019; Mikulyuk et al, 2020). The Partners could also actively accept change by encouraging lakeshore owners to increase tree growth along the shoreline, which would eventually increase the amount of coarse woody debris in the water, which creates more suitable ashigan habitat (Ahrenstorff et al, 2009).…”

Managing fisheries within a RAD framework: Concepts and applications

“…To explore the application of RAD strategies to managing invasions, Dunham et al (2022) used demographic models to evaluate the effects of nonnative brook trout S alvelinus fontinalis on native bull trout S. confluentus in the western United States. Resist strategies were simulated by periodic removal of brook trout, accept strategies involved no removal of brook trout, and direct strategies involved adding new bull trout to the population in alternate years.…”

“…Studies in this special issue suggest some major themes in applying the RAD framework in fisheries management. First, although resist is often the first response to unplanned changes in a fishery (Table 1), some fisheries have passed a point of no return to historic conditions (Dassow et al, 2022; Dunham et al, 2022; Feiner et al, 2022; Psuty, 2022; Rogers‐Bennett et al, 2022). The RAD framework provides a mechanism to systematically identify and compare a full range of options when resistance is not feasible.…”

“…While this set of studies is a start, more case studies and conceptual discussions can help inform RAD practitioners about what works or does not work. Failed mitigation strategies are likely as important as successful ones to inform the broader community about circumstances under which particular RAD strategies are effective (Dunham et al, 2022; Embke et al, 2022). Applying the RAD concept retrospectively to coupled socio‐ecological systems can identify circumstance where particular approaches were successful and thus provide guidance for future applications of resist , accept , or direct strategies (Rogers‐Bennett et al, 2022; Smith et al, 2022).…”

Exploring metapopulation‐scale suppression alternatives for a global invader in a river network experiencing climate change

“…Consequently, costs may increase, and the likelihood of success declines if suppression is deferred until after populations have fully established and are less vulnerable to stochastic events (Mack et al., 2000 ; Simberloff, 2003 ; van Poorten et al., 2019 ). In addition, socioeconomic beneficiaries (e.g., anglers of introduced salmonids) may resist control of invasive species (Beever et al., 2019 ; Dunham et al., 2022 ; Hansen et al., 2019 ).…”
