“…shared watersheds) of being able to provide a supply of immigrants that pose a recolonisation threat. Indeed, individuals from 32 % of pedigree inferred litters were captured in different river catchments, which is consistent with a previous analysis that showed that connectivity (a function of distance to, and number of, mink) to mink in adjacent areas was the strongest factor affecting mink capture rate within a subcatchment (Bryce et al 2011). Whilst 3 years of control were sufficient to massively reduce mink density within large river sections, as part of a mainland management area, the CWVCP only gradually achieved systematic coverage of adjacent river sections to eventually form a contiguous management area.…”

“…This study is framed around the Cairngorms Water Vole Conservation Project (CWVCP), which was initially conceived to protect remnant populations of water voles (Arvicola amphibius) in the headwaters of the Cairngorm Mountains in northeast Scotland, UK (Bryce et al 2011). The project was initiated following a catastrophic UK-wide decline in water vole distribution, which has been attributed to predation by the introduced and invasive American mink, and to protect the large continuous metapopulation networks of this species that persisted in the area (Aars et al 2001).…”

“…The mink raft (a mink-detection device that is anchored to the edge of a waterway consisting of a 120 cm 9 60 cm floating platform housing a clay paw print detection pad within a tunnel) network was used to delineate areas connected by mink rafts (using a 500 m buffer either side of a waterway), and an effort matrix was superimposed upon the landscape. Following Bryce et al (2011), effort was calculated from the time that a river subcatchment was fully covered by mink rafts (or where other appropriate forms of vigilance were in place e.g. active mink trapping by gamekeepers) according to the expert knowledge of the local mink control officer.…”

The compensatory potential of increased immigration following intensive American mink population control is diluted by male-biased dispersal

Attempts to mitigate the impact of invasive species on native ecosystems increasingly target large land masses where control, rather than eradication, is the management objective. Depressing numbers of invasive species to a level where their impact on native biodiversity is tolerable requires overcoming the impact of compensatory immigration from noncontrolled portions of the landscape. Because of the expected scale-dependency of dispersal, the overall size of invasive species management areas relative to the dispersal ability of the controlled species will determine the size of any effectively conserved core area unaffected by immigration from surrounding areas. However, when dispersal is male-biased, as in many mammalian invasive carnivores, males may be overrepresented amongst immigrants, reducing the potential growth rate of invasive species populations in re-invaded areas. Using data collected from a project that gradually imposed spatially comprehensive control on invasive American mink (Neovison vison) over a 10,000 km 2 area of NE Scotland, we show that mink captures were reduced to almost zero in 3 years, whilst there was a threefold increase in the proportion of male immigrants. Dispersal was often long distance and linking adjacent river catchments, asymptoting at 38 and 31 km for males and females respectively. Breeding and dispersal were spatially heterogeneous, with 40 % of river sections accounting for most captures of juvenile (85 %), adult female (65 %) and immigrant (57 %) mink. Concentrating control effort on such areas, so as to turn them into ''attractive dispersal sinks'' could make a disproportionate contribution to the management of recurrent re-invasion of mainland invasive species management areas.

“…The challenge, however, is to also empower those that are most affected by the decisions (the subjects), and some case studies have shown that mobilising stakeholders with low influence can be an effective way of building mass support for management initiatives. For example, a largescale eradication programme of the invasive American mink (Neovison vison) in north-eastern Scotland was possible due to the engagement of not only scientists, government agencies and national park authorities, but also local fisheries boards and local communities (Bryce et al, 2011). Likewise, in South Africa, engaging the public on the management of bass (Micropterus dolomieu) resulted in the bass angling fraternity providing full support for extirpation actions within selected sites of high conservation value (Weyl et al, 2014).…”

a b s t r a c tAlien species can have major ecological and socioeconomic impacts in their novel ranges and so effective management actions are needed. However, management can be contentious and create conflicts, especially when stakeholders who benefit from alien species are different from those who incur costs. Such conflicts of interests mean that management strategies can often not be implemented. There is, therefore, increasing interest in engaging stakeholders affected by alien species or by their management. Through a facilitated workshop and consultation process including academics and managers working on a variety of organisms and in different areas (urban and rural) and ecosystems (terrestrial and aquatic), we developed a framework for engaging stakeholders in the management of alien species. The proposed framework for stakeholder engagement consists of 12 steps: (1) identify stakeholders; (2) select key stakeholders for engagement; (3) explore key stakeholders' perceptions and develop initial aims for management; (4) engage key stakeholders in the development of a draft management strategy; (5) reexplore key stakeholders' perceptions and revise the aims of the strategy; (6) co-design general aims, management objectives and time frames with key stakeholders; (7) co-design a management strategy; (8) facilitate stakeholders' ownership of the strategy and adapt as required; and (9) implement the strategy and monitor management actions to evaluate the need for additional or future actions. In case additional management is needed after these actions take place, some extra steps should be taken: (10) identify any new stakeholders, benefits, and costs; (11) monitor engagement; and (12) revise management strategy. Overall, we believe that our framework provides an effective approach to minimize the impact of conflicts created by alien species management.

Controversies and consensus on the lionfish invasion in the Western Atlantic Ocean

ABSTRACT. This study investigates how the lionfish (Pterois sp.) invasion of the Western Atlantic Ocean has been socially constructed by natural scientists, the media, and stakeholders associated with various marine protected areas in the Caribbean. By examining the use of data and metaphors by these actors, I identify where invasion discourses converge and diverge. Although consensus exists regarding the non-nativeness, introduction vector, and successful establishment of lionfish throughout the region, I also identify uncertainty surrounding lionfish impact and controversies regarding lionfish management and control. The dominant discourse frames lionfish as a threat and control efforts as a war to keep the enemy at bay, and promotes lionfish hunting and consumption by humans: the "ultimate predators." However, this view is challenged by a coalition that questions the safety, effectiveness, and morality of the practices promoted by the kill-and-eat lionfish coalition. A nascent discourse that frames lionfish as fulfilling the role of overexploited native species, primarily expressed in socioeconomic terms, is shifting lionfish impact perception from negative to positive among some stakeholder groups. Whereas the dominant discourse views humans as helping nature to regain balance through lionfish hunting, a minority coalition views lionfish as part of the ecosystem, where a new equilibrium will be reached. This study shows that scientific data and metaphors, amplified by the media, facilitated initial understanding of the lionfish phenomenon and are used to legitimize claims. In time, however, local knowledge and societal values have intermingled with scientific data, sometimes challenging scientific discourses, and contributing to a richer understanding of the invasion as a social-ecological phenomenon.
