Van-KIRAP Communications Strategy - August 2022

SPREP Publications, Climate Change Resilience

Available Online

Howlett, Nick

The Vanuatu Klaemet Infomesen blong Redy, Adapt mo Protekt (VanKIRAP) project supports the Government of Vanuatu to institute a paradigm shift towards the standardised and mainstreamed use of science-based climate information, at multiple timescales to support resilient development pathways in Vanuatu.

Going to scale: reviewing where weve been and where we need to go in invasive vertebrate eradications

We are on the edge of the sixth mass extinction on Earth. Islands represent ca. 5% of the earths land area yet are home to 61% of extinctions in the past 500 years, and currently support 39% of critically endangered species. Invasive species are a leading cause of extinction and endangerment on islands. Invasive vertebrates, particularly mammals, are among some of the most damaging invasive species on islands. Eradicating invasive mammals is an increasingly utilised conservation tool. Nevertheless, conservation intervention needs greatly outstrip the island restoration communitys capacity. There are thousands of islands where invasive vertebrates are driving species toward extinction. So, how can the effort be matched to the scale of the problem? One approach is to improve outreach and communications to increase the resources available for projects. There are great stories; but these need to be told compellingly and repeatedly. Increasing social acceptance and support for invasive species eradications will reduce project costs associated with stakeholder engagement. Broadening the funding base can be accomplished by building stronger cost benefit valuations as well as engaging funders of climate change, marine conservation, human wellbeing, and food security. Furthermore, it is important to build upon existing partnerships to create or grow coalitions that can access these resources as part of broader, holistic efforts to address multiple conservation issues.

Only around a third of the worlds remaining forest cover survives in the form of Intact Forest Landscapes (IFL), and that proportion is declining.

Alien species as a driver of recent extinctions.

Cassey, P.

We assessed the prevalence of alien species as a driver of recent extinctions in five major taxa (plants, amphibians, reptiles, birds and mammals), using data from the IUCN Red List. Our results show that alien species are the second most common threat associated with species that have gone completely extinct from these taxa since AD 1500. Aliens are the most common threat associated with extinctions in three of the five taxa analysed, and for vertebrate extinctions overall.

Globally important islands where eradicating invasive mammals will benefit highly threatened vertebrates

Available Online

Holmes, Nick D [et al.]

Earths most highly threatened terrestrial insular vertebrates (111 of 1,184 species). Of these, 107 islands were in 34 countries and territories and could have eradication projects initiated by 2020. Concentrating efforts to eradicate invasive mammals on these 107 islands would benefit 151 populations of 80 highly threatened vertebrates and make a major contribution towards achieving global conservation targets adopted by the worlds nations.

Assessing species' vulnerability to climate change is a prerequisite for developing effective strategies to conserve them. The last three decades have seen exponential growth in the number of studies evaluating how, how much, why, when, and where species will be impacted by climate change. We provide an overview of the rapidly developing field of climate change vulnerability assessment (CCVA) and describe key concepts, terms, steps and considerations. We stress the importance of identifying the full range of pressures, impacts and their associated mechanisms that species face and using this as a basis for selecting the appropriate assessment approaches for quantifying vulnerability. We outline four CCVA assessment approaches, namely trait?based, correlative, mechanistic and combined approaches and discuss their use. Since any assessment can deliver unreliable or even misleading results when incorrect data and parameters are applied, we discuss finding, selecting, and applying input data and provide examples of open?access resources. Because rare, small?range, and declining?range species are often of particular conservation concern while also posing significant challenges for CCVA, we describe alternative ways to assess them. We also describe how CCVAs can be used to inform IUCN Red List assessments of extinction risk. Finally, we suggest future directions in this field and propose areas where research efforts may be particularly valuable.

Desecheo Island, Puerto Rico Island Conservation - preventing extinctions

Available Online

Desecheo Island supports important populations of plants, as well as animals found nowhere else in the world such as the Desecheo Anole, Desecheo Ameiva, and Desecheo Dwarf Gecko. Before the introduction of invasive rats, the island hosted large colonies of breeding seabirds, including the worlds largest Brown Booby colony and an important Red-footed Booby colony. But, due to the destruction of native vegetation and predation on eggs and chicks by these invasive rats, seabirds no longer nest on Desecheo and many plants and animals are threatened. Island Conservation and the U.S. Fish and Wildlife Service are working together to remove invasive rats from Desecheo Island. With the island free of invasive species, native plants and animals will once again be able to thrive in their natural habitat. Coral reefs in the Marine Reserve surrounding Desecheo (managed by the Department of Natural and Environmental Resources) are also expected to benefit from the islands restoration; increased vegetation will reduce soil erosion into the sea, and the seabirds will provide valuable nutrients to the adjacent marine ecosystems.

Invasive alien species surveys, Aleipata Islands, Samoa : September-December 2015

Samoa is part of the Polynesia-Micronesia Biodiversity Hotspot, one of 34 regions of the world where extraordinary levels of biodiversity and endemism are coupled with extremely high levels of threat (Mittermeier et al. 2004). The four Aleipata islands (Photo 1), holding a high percentage of representative and threatened species of Samoa, certainly represent a key site in the Polynesia-Micronesia biodiversity hotspot. In a 1986 review of 226 islands in the South Pacific region, these islands together rated 30th in importance for biological diversity (Vanderwoude et al. 2006). They were also more recently included in the list of the 7 Key Biodiversity Areas of Samoa (Conservation International et al. 2010).

A group of researchers, managers and tribal leaders with extensive local knowledge from Papua New Guinea, Solomon Islands, Vanuatu and Papua, Indonesia, provided new information on the status of leatherback nesting populations in the western Pacific Ocean. Twenty-eight nesting sites were identified, of which 21 were previously unknown or poorly described. Although data are still incomplete, we estimate a total of ca. 5000-9200 nests currently laid at 4 sites along the northwest coast (Bird's Head Peninsula) of Papua, Indonesia. Genetic analysis by using mitochondrial deoxyribonucleic acid sequences identified a total of 6 haplotypes among the 106 samples analysed for Solomon Islands, Papua and Papua New Guinea, including a unique common haplotype that is only found in these western Pacific populations. There was no significant difference in haplotype that is only found in these western Pacific populations. There was no significant difference in haplotype frequencies among these rookeries, which suggests that they represent a metapopulation composed of a single genetic rock. Further work is needed to define the demographic structure within this metapopulation.
