COP 28 special panel event hosted by Government of Niue and PRISMSS

SPREP Publications, Island and Ocean Ecosystems, BRB

Available Online

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.

Pacific Region Invasive Species Management Support Services (PRISMSS)

Mr Oudart leads the development of biosecurity detector canine teams based at the Faa’a International Airport in charge of controlling international and inter-island arrivals via air, as well as a team based at the commercial port in charge of ships, inter-island schooners and private sailboats. The efforts aim to strengthen border control under the EDF-funded PROTEGE project to avoid introduction of species such as red fire ants, fruit flies, and other harmful invasive species such as Citrus tristeza virus, coconut rhinoceros beetle and bee varroosis.

Wallis and Futuna drone-based rat removal

Available Online

4 years ago, Wallis and Futuna's Territorial Environment Service embarked on an ambitious journey to remove rats from the islets within the Uvea Lagoon. After completing the required training, community consultations and planning requirements, 4 islets were baited by hand and 9 islets were baited by drone. These islets are now safer for native biodiversity, allowing nature to restore itself and ultimately enhancing resilience against climate change. The healthy islets will be more productive, with more fruit, more crabs, less mosquitoes and more sea birds. This will have positive impacts on the surrounding coastal ecosystem such as reefs and fisheries, which communities rely on.

Predation of sea turtle eggs by rats and crabs

Stokes, H., Esteban, N., Hays, G. C.

Egg predation by invasive and native species may have severe impacts on endangered species and negatively affect species recovery. We assessed the levels of egg predation within green turtle (Chelonia mydas) clutches on the island of Diego Garcia (7.42°S, 72.45°E), Chagos Archipelago (Indian Ocean). Native coconut crabs (Birgus latro) and ghost crabs (Ocypode spp.), as well as introduced black rats (Rattus rattus), were predators of eggs, with these species entering nests via tunnels dug obliquely in the sand. Often whole eggs were removed from clutches. For example, the mean clutch size at oviposition (mean 127.8 eggs, n = 23, range = 74–176) was significantly larger than at the end of incubation (mean 110.9 hatched and unhatched eggs, n = 16, range = 9–147). In other cases, egg predation was recorded where the egg had been opened and contents were eaten in the nest. Overall, hatching success (the percentage of eggs laid leading to a hatchling emerging from the egg) was 64.9%, while 3.1% of eggs were predated within nests, 18.1% died during incubation without predation and 13.9% were removed. We reviewed evidence from 34 sites around the world identifying 36 predators that were either native (e.g., crabs, and goannas, n = 30) or invasive (e.g., rats, and pigs, n = 8). Depending on location, a predator could be identified as both native and invasive (e.g., dogs). We discuss how either nest protection and/or invasive predator eradication may be used to increase egg survival and when these approaches might be used.

Pacific Regional Invasive Species Management Support Service (PRISMSS)

In July SPREP signed a new Grant Funding Arrangement with the New Zealand Ministry of Foreign Affairs and Trade to provide further support to PRISMSS and PRISMSS activities in the region. The project PRISMSS-Restoring Island Resilience will take place up until mid-2026 and spend over NZD 20 million providing much needed human resources to both manage the PRISMSS and coordinate the PRISMSS programmes, develop further multi-country projects, continue with the mainstreaming activities and research initiatives, and invest in scaling up all five PRISMSS programmes across the region. The SPREP Invasive Species Adviser will continue to provide oversight and advice. We look forward to introducing you to the new team in 2024.

Biodiversity is a term that describes the number and diversity of the different plants, animals, and other living things within our environment. Biodiversity is a key factor in natural resilience to the impacts of environmental change. All species contribute to environmental resilience, including those that are naturally common and those that are rare. Natural biological communities have evolved over thousands or millions of years and have resulted in adaptations to local conditions that make these species resilient to natural environmental change. This community of native species contributes to ecosystem functioning and together provides the ecosystem services that we rely on. These services include provisioning (such as food, fuel, raw materials, or medicines), regulating (such as providing clean water and air, climate regulation and flood protection, waste decomposition, and biological pest and disease control), supporting (such as nutrient cycling), and cultural services (such as spiritual and heritage value, recreation, and science). When ecosystems are disturbed or disrupted, due to habitat modification, overharvesting, or invasive species, their function is affected, the benefits they offer decline, and resilience to further change is reduced. In this time of unprecedented global environmental change, protecting biodiversity is more important than ever to ensure we can retain the benefits of the natural world on which all our lives depend
