Invasive species

Como resposta a estas questões, foi desenvolvida uma classificação padronizada dos táxones exóticos, baseada na magnitude dos seus impactos ambientais.

Se ha elaborado una clasificación unificada de los taxones exóticos basada en la magnitud de su impacto ambiental (de aquí en adelante, la Clasificación del impacto ambiental de taxones exóticos, abreviada como EICAT por sus siglas en inglés) en respuesta a estas cuestiones. Se trata de un método sencillo, objetivo y transparente para clasificar taxones exóticos en cuanto a la magnitud de su impacto ambiental perjudicial en las zonas receptoras.

More than 70% of the earth is covered by oceans and major seas and there are more than 1.6 million kilometres of coastline. Yet our marine world is under threat: the most insidious is the one posed by marine invasive species. This booklet does not present new or primary information, but rather a synthesis of current issues and trends, including several examples of some of the worst marine invasive species, their spread and impact.

Marine invasive species can have a disastrous impact on biodiversity, ecosystems, fisheries, human health, tourism and coastal development, and they can be extremely difficult and costly to control.

A unified classification of alien taxa based on the magnitude of their environmental impacts has been developed in response to these issues. EICAT (Environmental Impact Classification for Alien Taxa) is a simple, objective and transparent method for classifying alien taxa in terms of the magnitude of their detrimental environmental impacts in recipient areas.

The northwest boreal region of North America is a land of extremes.

The papers in this volume were, with a few exceptions, presented at the third Island Invasives conference, held in Dundee, Scotland in July 2017.  The papers demonstrate up-scaling in several aspects of eradication operations – not least in ambition, land area, operational size, global reach and of course financial cost.
