Invasive species

Las ‘especies invasoras’ (a menudo llamadas plagas, malas hierbas o enfermedades) son plantas, animales, agentes patógenos y otros organismos que han sido transportados por los humanos más allá de los límites de su rango nativo de distribución (ya sea deliberada o involuntariamente) y que se vuelven destructivos para el medio ambiente y los medios de subsistencia humanos. Las islas y su área costera marina son particularmente vulnerables a las especies invasoras - debido a que

Les 'espèces envahissantes' (souvent appelées ravageurs, mauvaises herbes ou même maladies) sont des plantes, des animaux, des agents pathogènes et d’autres organismes qui sont délibérément ou involontairement emmenés au-delà de leur aire de répartition naturelle par des personnes et qui deviennent destructeurs de l’environnement ou des moyens de subsistance.

‘Invasive species’ (often called pests, weeds and diseases) are plants, animals, disease agents and other organisms taken beyond their natural range by people, deliberately or unintentionally, and which become destructive to the environment or human livelihoods.

This overview of the roles of alien species in insect conservation brings together information, evidence and examples from many parts of the world to illustrate their impacts (often severe, but in many cases poorly understood and unpredictable) as one of the primary drivers of species declines, ecological changes and biotic homogenisation. 

Introduced mammalian predators are one of the greatest threats to wildlife worldwide; this is especially so at the sub-Antarctic island of South Georgia. This publication reports on the conclusion of the five-year (2011-2015) operational phase of the eradication of rodents from South Georgia, undertaken to restore the millions of seabirds (and other species) lost to rats over the last 240 years. 

This report provides a first comprehensive overview of marine conservation efforts in the European Overseas: In the context of rapid global development in these areas, it takes stock and pinpoints the actions required to improve marine protection and strengthen resilience in these diverse territories and to reconcile this with the opportunities provided by development of the blue economy and the challenges in the face of climate change.

This publication presents the structure, the particulars, the methods for identifying and prioritizing the invasive alien species issues, the information derived from the invited presentations and the posters, as well as the outcomes of the conference "Freshwater Invasives - Networking for Strategy (FINS)" of the Inland Fishers Ireland (IFI) and the European Inland Fisheries and Aquaculture Advisory Commission (EIFAAC). 

Esta publicación ha sido preparada por las Asociaciones GloBallast, la IOI, el CSIR-NIO y la UICN para que sirva de orientación a quienes tienen previsto hacer un reconocimiento biológico portuario de referencia, en especial en relación con la gestión del agua de lastre. 

Invasive alien species (IAS) have been identified as one of the most important direct drivers of biodiversity loss and ecosystem service changes. Many international policy instruments, guidelines and technical tools have been developed to address this threat.

This publication has been prepared by GBP, IOI, CSIR-NIO and IUCN in order to serve as guidance to those who are planning to carry out a port biological baseline survey, in particular in the context of Ballast Water Management.
