Alien species

Este manual es la respuesta a las peticiones de los países para una estrecha colaboración y desarrollo nacional del marco regulatorio relacionado con las Especies Exótica Invasoras (EEIs) en particular en lo que se refiere a la posible transferencia de organismos potencialmente nocivos y patógenos en el agua de lastre y sedimentos de los buques.

This booklet describes some of the plants present in and around Lake Tanganyika that can affect its environment and biodiversity. There are many such plants and there will be more, but this small volume is a starting handbook to invasive plant recognition, understanding and management. It contains a selection of species that can are known to be invasive in other situations and some that have already begun to show that tendency in Lake Tanganyika and/or its catchment.

The overall aim of this study is to bring together information on the subject of gender and invasive species, and thereby inform and strengthen future projects, activities and interventions in relation to invasive species prevention and management. The information will be of interest to all those involved in research, policy and practice of invasive species prevention and management.

This manual is the product of countries’ requests for assistance in strengthening and developing national regulatory frameworks related to marine Invasive Alien Species (IAS) in particular with respect to the transfer of potentially harmful aquatic organisms and pathogens in ships’ ballast water and sediments. It is directed at national level practitioners as a hands-on guide to the development of national ballast water management strategies.

Más del 70% de la tierra está cubierta por océanos y mares mayores y hay más de 1,6 millones de kilómetros de costa. Sin embargo, nuestro mundo marino está en peligro: la peor amenaza es la de las especies marinas invasoras. El folleto no presenta información nueva o primordial, sino más bien una síntesis de las cuestiones y tendencias actuales, incluyendo varios ejemplos de algunas de las peores especies marinas invasoras, su propagación e impacto.

Plus de 70% de la terre sont couverts par les océans et les mers les plus importantes, et l’on compte plus de 1,6 million de kilomètres de côtes. Mais notre monde marin est en danger : la menace la plus insidieuse est celle que causent les espèces invasives marines.

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.
