The purpose of this guide is to provide simple factsheets on priority invasive alien pests that currently threaten plant health, human health and/or biodiversity in the Pitcairn Islands (Pitcairn, Henderson, Ducie and Oeno Islands), a UK Overseas Territory located in the southern Pacific Ocean. It also identifies the main pathways of introduction so that biosecurity inspections can be targeted. The guide is intended to be used by those working in biosecurity, and by all those interested in preserving the unique environments and biodiversity found in the Pitcairn Islands. The guide will not enable the user to accurately confirm the identity of the species of suspected invasive alien pest included in this guide, and further assistance will be required from a relevant specialist.
This guide is intended to be used by those working in biosecurity and plant health, and by all those interested in preserving the unique environments and biodiversity found in the Caribbean UKOTs. The guide will not enable the user to identify to species all the invasive invertebrate plant pests that they may encounter, but it does provide advice on how to collect and preserve specimens for further study and where to seek assistance.
This guide is intended to be used by those working in biosecurity, with the aim of empowering the Biosecurity Officer and other government officers in South Georgia to rapidly detect nonnative species of terrestrial invertebrates caught on sticky traps. It is not intended to enable government staff to identify terrestrial invertebrates to species level, for this further assistance will be required from a relevant specialist, but it will help staff to detect and prioritise potential invasive species.

Le Centre assure lélaboration de méthodes, le développement de formations, la capitalisation des connaissances et la diffusion de savoir-faire et de bonnes pratiques. Il consacre ainsi son activité à toutes les EEE de faune et de flore, en milieux terrestres, marins et deau douce, en métropole comme en outre-mer.
The rose-ringed parakeet (RRP), Psittacula krameri, has become established in at least four Pacific Island countries (Hong Kong China, Japan, New Zealand, U.S.A.), including the Hawaiian islands of Kauai, Oahu, and Hawaii. Most Pacific islands are at risk of RRP colonization. This species was first introduced to Hong Kong in 1903 and Hawaii in the 1930s1960s, established since 1969 in Japan, and in New Zealand since 2005 where it has repeatedly established after organized removals. The founding birds were imported cage-birds from the pet trade. In native India, RRP are generally found associated with human habitation and are considered a severe agricultural pest. In the Hawaiian Islands, RRP are increasing and expanding their geographic ranges below 500m elevation. Population estimates in 2018 on Kauai were ?6,800 birds, which was a three-fold increase and a 22.5% annual growth rate in the prior 6 years, whereas Oahu had ?4,560 birds with a 21% annual growth rate the prior 9 years; these rates suggest a population doubling time of ?3.5 years. Wild RRP can live 14+ years, can reproduce after 1.5 years, and have few effective predators. Breeding pairs produce 13 fledglings annually. RRP are seed predators and rarely seed dispersers; their flock-foraging behavior can result in severe damage to orchard and field agricultural crops including tropical fruit and corn (Zea mays), and such economic damages are especially pronounced on Kauai. Island societies should prevent new introductions and consider RRP deterrents and population control methods to protect resources.
In 2012 a process was initiated to produce a guidance document for invasive species management on islands, as an objective of a regional invasive species project in the Western Indian Ocean (WIO) islands, implemented by IUCN. The consultative process for producing the document began with requests and discussions via regional and global island and invasives email distribution lists. Initial responses revealed a consensus on the need for a guidance document for programmatic planning. A draft was therefore constructed around existing Pacific regional guidelines and a draft manual that had initially been written for the WIO, with new supplementary sections suggested by respondents. The new draft was discussed and revised in workshops at two international conferences. The document is now organised into three main sections: the first on how to use it, the second a checklist of the essential components of a comprehensive island invasives programme (to ensure nothing is overlooked when planning), and the third providing detailed guidance on the planning and decision-making processes. The document is intended to provide a comprehensive framework and procedural guide for invasive species planning on islands. Further consultations took place by email, and a later draft was tested by a number of users writing various kinds of invasive species strategy and action plan. Publication will be in English, French (both published 2018) and Spanish (scheduled for 2019).
Recent years have seen large increases in the number and size of successful invasive species eradications from islands. There is also a long history of large scale removals on larger land-masses. These programmes for mammals and terrestrial plants follow the same cost-area relationship although spanning 10 orders of magnitude in scale. Eradication can be readily defined in island situations but can be more complex on larger land-masses where uncertainties defining the extent of a population, multiple population centres on the same land-mass and ongoing risks of immigration are commonplace. The term complete removal is proposed to describe removal from an area with ongoing eff ort to maintain the area as clear, as features in many larger scale mainland programmes. Examples of complete removal to a boundary, in patches and in habitat islands are discussed. While island eradications continue to grow in scale, new legislation such as the lists of Species of European Union Concern will also drive increasing management on larger land-masses. However, these lists include large numbers of species that are already widespread. Methods are needed to prioritise species to reflect both the risks posed and the feasibility of management, including the effects of scale on cost and effectiveness.
