First reviewing how invasive species threaten ecosystems, public health, and economies, Gérard Rocamora and Elvina Henriette then explore the importance of invasive species management in ecological restoration on islands and the recovery of threatened species. Highlighting the Seychelles' success in eradicating and controlling invasive vertebrates, the book goes on to provide detailed species accounts of the islands' main invasive plants and animals. Covering forty-four invasive species, the book includes distribution maps, details on ecology and specific threats posed, information on control and eradication attempts in the Seychelles and the region at large, and management recommendations.

Tropical island species and ecosystems are threatened worldwide asa result of increasing human pressure. Yet some of theseislands also lend themselves to restoration, as they are physicallydefined units that can be given focused attention, as long asresources are available and clear conservation targets areset. Cousine Island, Seychelles, is a tropical island thathas received such intensive restoration. From a highlydegraded island in the 1960s, the island has now been restored towhat is believed to be a semblance of the natural state. Allalien vertebrates have been eradicated, as have 25 invasive alienplants. Cultivated plants are now confined to one smallsection of the island. Poaching of nesting marine turtles hasbeen stopped, leading to an increase in turtle breedingnumbers. The shearwater population has increased in size withpoaching activities under control. The Sooty tern has alsoreturned to the island to breed. The coastal plateau has beenrestored with over 2500 indigenous shrubs and trees, which have nowgrown into a forest carpet. There are strict quarantine procedureson the island, keeping it free of rats, mice, various alieninvertebrates and potentially invasive alien plants. Threethreatened Seychelles endemic land birds (Seychelles warbler,Seychelles magpie robin and Seychelles white-eye) have beenintroduced and are thriving, with these introductions contributingto both the magpie robin and the white-eye being downgraded from CRto EN (the warbler remains at VU). Ecotourism, and natureconservation for the local inhabitants, have been introduced in away that does not reduce the improved compositional, structural andfunctional biodiversity of the island. The result of therestoration effort appears to be sustainable in the long term,although challenges still remain, especially with regards toadequate clean water and a non-polluting power supply on theisland. Cousine is thus paving the way in the art and scienceof tropical island restoration as a legacy for future generations. There is no other book available on this case study. Theneed for the book arises from the fact that here is a positive notefor conservation in these times of so much negative news on thestate of our environment. More importantly, the book showshow such restoration should be done, and is therefore a model formany other islands around the world. The book has manyillustrations so as to give the book wide appeal and literally toshow what can done in terms of restoration. All this is basedon much scientific detail, including many new data. The aimis, by way of example, to demonstrate how practical restoration,based on sound scientific research, can be carried out for thebetterment of ecological integrity and ecosystem health.

INVASIVE ALIEN SPECIES Invasive Alien Species: Observations and Issues from Around the World Volume 1: Issues and Invasions in Africa Invasive alien species are spreading into new ecosystems each year. The impacts caused by these invaders can be swift and devastating. The topic of invasive alien species is large, complex, and globally significant at various scales, exacerbated by the globalization of world economies and increased trade and commerce that has overcome natural barriers to species movement. Invasive alien species threaten global food supplies, water quality and availability, and energy production and delivery. With the added risks associated with global climate change, the global homogenization of plants, animals, and microbes is a major factor in the decline in ecosystem health and ecosystem services worldwide. To counter this trend, there is a critical need to unify governments, cultures, and programs to improve cross-boundary coordination to effectively address the wide range of invasive alien species threats to the environment, economies, and to plant and animal health; particularly human health. This 4-volume work is the first to compile a set of useful material for key topics, to provide a better understanding of the overall global threat of invasive alien species and the diverse array of problems faced around the world, and assemble material that includes potential replicable solutions to overcome these threats. The books also highlight the threat posed by invasive alien species in terms of a global ‘call to action’. Since invasive species know no boundaries, it is our hope that by compiling material from different scientific and social perspectives around the world, and sharing knowledge and examples of a diverse array of associated topics, we can advance global awareness and improve unified national responses to the threat posed by invasive alien species.

While the issue of invasive alien species (IAS) has important biological components, the human dimensions deserve much greater attention. Humans, with all their diversity of quirks, strengths, and weaknesses, are at the heart of the problem of IAS and, paradoxically, also at the heart of the solution. This compilation of papers delivered during a workshop on the human dimensions of the IAS problem, held in Cape Town, South Africa on 15-17 September 2000, covers some of the many causes, consequences and responses to this problem.

Includes papers and abstracts dealing with eradication of invasive species in Alaska, Australia, Baker Island, California, Christmas Island, Enderby and Rose Islands, Galapagos Islands, Hawaii, Howland Island, Japan, Jarvis Island, Laysan Island, Lord Howe Island, Mauritius, Mexico, Nauru, New Zealand, Northern Ireland, Northern Mariana Islands, Saint-Paul Island, Seychelles, West Indies.

The spread of invasive alien species (IAS) is creating complex and far-reaching challenges that threaten both the natural biological riches of the earth and the well being of its citizens. While the problem is global, the nature and severity of the impacts on society, economic life, health, and natural heritage are distributed unevenly across nations and regions. Thus, some aspects of the problem require solutions tailored to the specific values, needs, and priorities of nations while others call for consolidated action by the larger world community. Preventing the international movement of invasive alien species and coordinating a timely and effective response to invasions will require cooperation and collaboration among governments, economic sectors, non-governmental organisations, and international treaty organisations. This strategy highlights the dimensions of the problem and outlines a framework for mounting a global-scale response. While both the problem and the scale of the solution may appear dauntingly complex, the issue presents an unparalleled opportunity to respond with actions that link preservation of biodiversity with protection of the health and livelihood of the world's human populations.
