“…(ii) From the mid-1980s, attempts were increasingly made to eradicate introduced mammals, particularly rats, from islands, and these eradication attempts were greatly facilitated by the availability of potent second-generation anticoagulant toxins and the adoption of navigational guidance systems for aircraft laying baits (Towns et al 2013). (iii) Since the 1990s, there has been increasing public acceptance of the importance of predator control to reduce predation of native wildlife (Russell 2014) and an increasing focus on suppressing rats and stoats as well as possums (which are also predators) in mainland forests.…”

Summary In 2014, baits laced with the poison sodium fluoroacetate (1080) were sown over 694 000 ha of mostly native beech forests in New Zealand to control rats, stoats and possums – a landscape‐scale pest control programme called ‘Battle for our Birds’. This large pest control operation was necessitated by the mast seeding of beech trees which led to irruptions of rodent and stoats which were predicted to lead to decreases in vulnerable native wildlife. In this article, we describe why and how this extensive pest control programme was developed and implemented. We describe the seedfall monitoring that was used to determine the need for large‐scale rodent and stoat control and the response of these predators to this control. We also provide a summary of the bird monitoring that was undertaken to demonstrate the effectiveness or otherwise of the programme.

“…For example, some pest control regimes may not be tenable because of ethical or social issues such as the use of inhumane anticoagulant poisons or the application of toxins onto public land (Maguire 2004;Warburton & Norton 2009;Beausoleil et al 2010;Russell 2014). Similarly, there may be pressure to maintain or increase levels of native forest cover in a landscape because of the cultural or recreational values that native forests provide, even if pest control would have provided greater benefits to biodiversity (Jamieson 2008).…”

Effective biodiversity conservation in lowland New Zealand requires an understanding of the relative benefits of managing impacts of native forest loss versus controlling invasive species. We used bird count data from 195 locations across mainland northern New Zealand to examine how the abundance and richness of native forest birds varied across wide gradients of native forest cover (c. 0-100%) and intensity of invasivespecies control ('eradication', 'high-intensity rat and possum', 'low-intensity rat and possum', 'periodic possum' and 'none'). Most response variables were significantly affected by forest cover, and this effect was typically non-linear: response variables declined rapidly below c. 5-10% forest cover, but were relatively invariant to forest cover above this point. Pest control was found to affect surprisingly few species, with only kereru (Hemiphaga novaeseelandiae) and tui (Prosthemadera novaeseelandiae) being more abundant at pest controlled than uncontrolled sites for any pest control category. Species richness and 'total abundance' (abundance of all species combined) also increased at pest controlled sites, but effects were largely driven by responses of tui and kereru. Effects of eradication were far larger than effects of other pest control categories, while it was unclear whether 'low-intensity rat and possum' or 'periodic possum' control had any effects at all. Our results suggest that both managing levels of forest cover and controlling invasive mammals can benefit native forest birds, but the occurrence and magnitude of these benefits will be context-dependent. Managing forest cover may be relatively unimportant in landscapes with >5-10% forest cover, while benefits of pest control may be limited unless intensive methods are used. Moreover, even intensive pest control may only benefit a small subset of species unless coupled with reintroduction of locally-extinct species. Combining these results with knowledge of the financial, ethical, and social constraints of different management options should provide a solid foundation for effective conservation decision-making in lowland environments.

“…The management of IASs on islands, or indeed anywhere, must therefore be considered as part of a broader exercise of engagement within a coupled socio-ecological system (Crowley et al 2017;Schmitz et al in press). Conflicts of interest can arise in IAS management when species that are considered invasive by one sector of society are considered a resource by another (Russell 2014). Important examples include game animals, pets and ornamental plants.…”

Invasive alien species on islands: impacts, distribution, interactions and management

et al. 2017

SUMMARYInvasive alien species (IASs) on islands have broad impacts across biodiversity, agriculture, economy, health and culture, which tend to be stronger than on continents. Across small-island developing states (SIDSs), although only a small number of IASs are widely distributed, many more, including those with greatest impact, are found on only a small number of islands. Patterns of island invasion are not consistent across SIDS geographic regions, with differences attributable to correlated patterns in island biogeography and human development. We identify 15 of the most globally prevalent IASs on islands. IAS impacts on islands are exacerbated through interactions with a number of other global change threats, including over-exploitation, agricultural intensification, urban development and climate change. Biosecurity is critical in preventing IAS invasion of islands. Eradication of IASs on islands is possible at early stages of invasion, but otherwise is largely restricted to invasive mammals, or otherwise control is the only option. Future directions in IAS management and research on islands must consider IASs within a broader portfolio of threats to species, ecosystems and people's livelihoods on islands. We advocate for stronger collaborations among island countries and territories faced with the same IASs in similar socio-ecological environments.
