To engage broader audiences at the Adaptation Futures 2025 conference, PRISMSS launched an interactive video quiz using Pacific humour, featuring the renowned Pacific comedian, Tofiga, to educate viewers on invasive species in a fun and culturally resonant way. The interactive quiz called, Ohh…That’s a bit Invasive, has received positive responses for its creativity and effectiveness in raising awareness on sustainable invasive species management in the Pacific. Participate in this quiz from the comfort of your home and come laugh, learn and battle the baddies of the Pacific with the PRISMSS interactive video quiz on invasive species that’s part science, part stand-up, and all heart. A quiz so funny, even the invasive species want to join. Learn how they impact biodiversity, island resilience & climate change, discover how Pacific partnerships are fighting back sustainably, gut-busting laughs, yes, learning can be funny and smarter brains thanks to our interactive video quiz

The Pacific Island nation of Niue was a leading voice at the recent COP28, calling for efforts to significantly scale up investment in the management of invasive species as a key action for increasing the climate resilience of vulnerable island nations.

Managing Invasive Species to Create a Great Green Line of Defense for the Pacific. Controlling invasive species is one of the most effective tool for restoring island resilience.

Invasive Alien Species (IAS) are a major threat to marine, freshwater and terrestrial biodiversity of the Pacific islands and to the people there that depend on biodiversity for their livelihoods. Invasive species are implicated in the decline of hundreds of species in the region. Participating Pacific states and the executing agency SPREP (Secretariat of the Pacific Regional Environment Programme) recognised the need to implement the regional IAS strategy, “Guidelines for Invasive Species Management in the Pacific. A Pacific strategy for managing pests, weeds and other invasive species” (hereafter, the Guidelines) and develop and implement national IAS plans and strategies. The Guidelines were originally identified as a product under this project, but were completed in 2009 prior to writing this proposal. As envisaged during the PIF process the proposed project contributes to the implementation of the Guidelines, each country’s National Biodiversity Strategy and Action Plan and helps each to meet its responsibilities under Article 8 (h) of the CBD and several other international agreements addressing IAS. The three main components (not including components related to project management) of the proposed project are designed to capture outcomes and outputs described in the Project Identification Form but they have been reorganized to follow the structure of the Guidelines.

Introduced rats (Rattus spp.) can affect island vegetation structure and ecosystem functioning, both directly and indirectly (through the reduction of seabird populations). The extent to which structure and function of islands where rats have been eradicated will converge on uninvaded islands remains unclear. We compared three groups of islands in New Zealand: islands never invaded by rats, islands with rats, and islands on which rats have been controlled. Differences between island groups in soil and leaf chemistry and leaf production were largely explained by burrow densities. Community structure of woody seedlings differed by rat history and burrow density. Plots on islands with high seabird densities had themost non-native plant species. Sincemost impacts of rats were mediated through seabird density, the removal of rats without seabird recolonization is unlikely to result in a reversal of these processes. Even if seabirds return, a novel plant community may emerge.

Predators play a critical role in ecosystems; however, when overly abundant, they can disrupt natural processes and cause extinctions of species. In particular, oceanic islands have endured many impacts of introduced mammalian predators. Whereas knowledge and management of introduced mammalian predators on islands is well advanced in natural landscapes, in inhabited landscapes, spanning rural and urban environments, comparatively less is known. We summarise key issues from the natural and social sciences in the management of introduced mammalian predators in inhabited landscapes of Aotearoa–New Zealand. We describe the shift in focus over the past few decades from management of introduced mammalian herbivores to predators in rural environments, and the growth in management of introduced mammalian predators in urban environments, both seeking to emulate conservation gains made in forested landscapes. We discuss the circumstances around companion animal management at the interface of the natural and social sciences. We summarise surveys of attitudes towards introduced mammalian predators, the role of biodiversity comanagement between Ma¯ori and Pakeha, and the importance of also considering non-biodiversity benefits from introduced predator management. We describe the rise of community predator control and large landscape projects aspiring for a ‘Predator Free New Zealand’, and how such an aspiration must be concurrent with habitat restoration. We make recommendations for further research on the basic population biology of predators in inhabited landscapes, and more long-term studies. Such studies should be integrated with examination of the motivations for predator management, as well as the biodiversity and social outcomes of such management. We conclude by remarking that introduced predator management is only one component of a robust national strategy for conservation of native biodiversity in New Zealand.

New Zealand, an archipelago of more than 2000 islands, has a terrestrial fauna especially depauperate in native land mammals. Kiore (Rattus exulans) was the first of four rodent species introduced by people. A project to eradicate invasive rats from Kapiti Island in 1996, represented a turning point in the technology, complexity and scale at which managers of natural heritage on New Zealand islands could operate. This paper includes case studies of some significant projects targeting rodents, sometimes with other introduced mammals, undertaken in the 12 years following Kapiti. Details of the methods, costs, results and outcomes are provided for Kapiti, Whenua Hou, Tuhua, Campbell, Raoul, Hauturu, Taukihepa, and Pomona islands, collectively representing a total of over 23,000 ha of habitat cleared of introduced mammals. Research and trials undertaken in the Kapiti project provided the basis for future environmental risk assessments, allowing other projects to focus on knowledge gaps. New trends in invasive species eradication in New Zealand include more challenging multi-species eradication projects, some of which are undertaken by self- funded community groups. To summarise the lessons of the New Zealand experience: a programmatic approach is recommended which will fit each eradication within a context or framework of goals for those islands; address biosecurity issues at the outset; build capability to attempt the most challenging and rewarding projects; facilitate investment in monitoring and manage expectations of stakeholders to ensure their ongoing support. Success breeds success but is never guaranteed.

Eradication of introduced species from inhabited islands requires consideration of both technical and social feasibility. Historically, biologists have struggled to engage successfully in the social components of eradication planning. Island communities have unique features that require consideration in eradication planning. Social impact assessment is a powerful planning tool used widely outside of wildlife management. We outline the core components of a social impact assessment as it could be applied to eradication planning on inhabited islands. We summarise previous experience in social impact assessment and community engagement for introduced predator eradication on inhabited islands, and as an example develop a social profile for inhabited islands of the Hauraki Gulf of New Zealand. We conclude that social impact assessment has great potential to improve eradication feasibility assessment, and should be applied routinely in eradication scoping on inhabited islands.
