The catastrophic impact of invasive mammalian predators on birds of the UK overseas territories: a review and synthesis

Available Online

Cuthbert, Richard J.

Hilton, Geoff M

The UK has sovereignty over 16 Overseas Territories, which hold some of the world's great seabird colonies and collectively support more endemic and globally threatened bird species than the whole of mainland Europe. Invasive alien mammalian predators have spread throughout most of the Territories, primarily since European expansion in the 16th century. Here we review and synthesize the scale of their impacts, historical and current, actions to reduce and reverse these impacts, and priorities for conservation. Mammalian predators have caused a catastrophic wave of extinctions and reductions in seabird colony size that mark the UKOTs as a major centre of global extinction. Mammal-induced declines of threatened endemics and seabird colonies continue, with four Critically Endangered endemics on Gough Island (Tristan da Cunha), St Helena and Montserrat directly threatened by invasive alien House Mice Mus musculus, Feral Cats Felis catus and rats Rattus spp. Action to reduce these threats and restore islands has been modest in comparison with other developed countries, although some notable successes have occurred and a large number of ambitious eradication and conservation plans are in preparation. Priority islands for cosnervation action against mammalian predators include Gough (which according to one published prioritization scheme is the highest-ranked island in the world for mammal eradication), St Helena and Montserrat, but also on Tristan da Cunha, Pitcairn and the Falkland Island. Technical, financial and political will is required to push forward and fund the eradication of invasive mammalian predators on these islands, which would significantly reduce extinction risk for a number of globally threatened species.

Pacific island nations are already experiencing the effects of a changing climate. Cyclones and severe flooding have hit Yap, Niue and Fiji recently. Air temperature, the number of cyclones and sea level are all predicted to rise, and changes in rainfall are also predicted across the Pacific (1). Forces driving climate change are beyond the control of island nations. Pacific islands, while constituting 0.12 per cent of the worlds population, release only 0.003 per cent of the worlds carbon dioxide from fuel combustion (2) . Adaptation to climate change should now be the focus of Pacific Island nations. The most practical climate-change adaptation action is to improve ecosystem resilience and focus on sustainable development.

Inventory of alien birds and mammals in the Wallis and Futuna archipelago

Theuerkauf, Jorn...[et al.]

In November 2007 and November 2008, we conducted a bird and mammal survey on Wallis and Futuna. We found two non-native bird species on Wallis: the Common Myna (Acridotheres tristis) and the Chestnut-breasted Munia (Lonchura castaneothorax), and one on Futuna: the Jungle Myna (Acridotheres fuscus). We also recorded Black Rats (Rattus rattus) on Futuna, a recent introduction to this island. The introduction of 3 bird species and Black Rats in the last decade denotes a lack of preventive measures and demonstrates that the issue of invasive species has not received sufficient priority

Making protected areas relevant: a guide to integrating protected areas into wider landscapes, seascapes and sectoral plans and strategies

Climate Change Resilience, BRB

Life on Earth is disappearing fast and will continue to do so unless urgent action is taken. Well designed and effectively managed systems of protected areas are a vital tool for reducing biodiversity loss while delivering environmental goods and services that underpin sustainable development. There are currently over 130,000 protected areas worldwide, covering around 13.9 % of the Earths land surface and 5.9 % of the territorial marine surface. These areas represent a tremendous resource for conserving biodiversity and for protecting vital ecosystem services. The worlds protected areas exist in a rapidly changing world. There are many issues facing protected areas, including climate change, invasive species, fragmentation of natural ecosystems, increasing urbanisation and growing demands upon natural resources. Consideration of protected areas must be framed within this context of global change

Steiner, Achim

A Workshop on Regional Action to Combat Invasive Alien Species on Islands to Preserve Biodiversity and Adapt to Climate Change highlighted successes, deepened connections within regions and facilitated the exchange of experiences across regions.While discussions outlined significant obstacles to invasive alien species management2 on islands, they also showcased how targeted successes have led to major gains for conservation and development.Collaboration across developmental and environmental sectors and sustained support are critical to success in this field.Exciting new initiatives are developing to demonstrate large-scale management of invasive alien species across island regions. Next steps to accelerate and expand national, regional and international action and successful outcomes were agreed.The workshop outcomes will help drive effective management of invasive alien species threats to island livelihoods and biodiversity at local, national, regional and international levels.

A priority for Small Island Developing States (SIDS) is effective planning and financing of actions to address the impacts of climate change. This paper examines the vital role that regional institutions play in sharing SIDS relevant approaches and knowledge, and in delivering specialist skills and knowledge to support national efforts. It goes on to highlight the work of the Climate Resilient Islands Partnership, which links the Caribbean, Indian Ocean and Pacific Regions, and is working to rapidly scale-up cost-effective services to SIDS through inter-regional cooperation and exchange.

Invasive species and climate change.

Available Online

Climate change is expected to cause extinctions when native plants and animals are prevented from migrating out of their hotter or drier habitats to more suitable climates. But for many species a more imminent or serious threat will be the opportunities created by climate change for invasive species to proliferate and cause more harm. Invasive species have already caused many extinctions and are one of the major causes of decline of native species and ecosystem degradation. The 2009 assessment of the vulnerability of Australias biodiversity to climate change noted that in many cases the impacts of invasive species benefiting from climate change are likely to exceed the direct impacts of climate change.

Rapid recovery of damaged ecosystems

Background: Recent reports on the state of the global environment provide evidence that humankind is inflicting great damage to the very ecosystems that support human livelihoods. The reports further predict that ecosystems will take centuries to recover from damages if they recover at all. Accordingly, there is despair that we are passing on a legacy of irreparable damage to future generations which is entirely inconsistent with principles of sustainability. Methodology/Principal Findings: We tested the prediction of irreparable harm using a synthesis of recovery times compiled from240 independent studies reported in the scientific literature. We provide startling evidence that most ecosystems globally can, given human will, recover from very major perturbations on timescales of decades to half-centuries. Significance/Conclusions: Accordingly, we find much hope that humankind can transition to more sustainable use of ecosystems.

The distribution and abundance of an invasive species: the common myna (Acridotheres tristis) on Atiu, Cook Islands

Mitchell. J.

An invasive alien species are known to cause significant economic and environmental damage. Islands are much more vulnerable to the invasion of invasive alien species, and have higher rates of extinction. In the islands of the South Pacific, there are several species Polynesian land birds which are threatened with extinction due to invasive alien species and human interference. Without any intervention from humans, it is likely that these birds will suffer extinction in the next few decades. The island of Atiu in the Cook Islands (South Pacific) supports a range of avian fauna. In 2007 the Rimitara lorikeet (Vini kuhlii), also known locally as the Kura was introduced to Atiu, to make a reserve population, as there were only approximatley 1000 left on the island of Rimitara, French Polynesia. There is concern for this species on Atiu due to the existence of the common myna (Acridotheres tristis). The myna is an aggressive invasive which is one of the worlds worst 100 invasive species. It was introduced to the Cook Islands by the government, with the intention to control the coconut-stick insect (Graeffea crouani), but is now a pest itself. A myna control programme on Atiu is being coordinated and controlled by Gerald McCormack (Cook Islands Natural Heritage Trust), working through George Mateariki, and using funding from various conservation organisations. Poisioning is being carried out by George in order to reduce myna numbers, and a bounty has been set on the birds or for every right foot so that the locals can help as much as possible. This investigation aimed to estimate the total population size on the island to use as a starting count to determine whether the programme is successful or not. Two methods were used which included roost counts to find an estimate of the population, and a transect method using a Distance programme to estimate the number of birds per hectare as well as the level of abundance in various habitat types. The two methods had overlapping results, giving a total estimated range of 3250 to 8460 birds on the island, although it is more likely to be at the higher end of this estimate at around 6000 to7000 birds. Further investigation will need to determine any change in the population size, any changes in habitat composition as well as the impact on the native species, especially the effect on the Kura and its population size.
