11,000 alien species invade EuropeNovember 21, 2008Halle/Saale. For the first time it is now possible to get a comprehensive overview of which alien species are present in Europe, their impacts and consequences for the environment and society. More than 11,000 alien species have been documented by DAISIE (Delivering Alien Invasive Species Inventory for Europe), a unique three year research project with more than 100 European scientists, funded by the European Union that provides new knowledge on biological invasions in Europe. Biological invasions by alien species often result in a significant loss in the economic value, biological diversity and function of invaded ecosystems. Harmful visitors The majority of these 11,000 alien species are however, not harmful. About 15 percent of these alien species cause economic damages and 15 percent cause harm to biological diversity, that is the environment, habitats and native plants, animals and micro-organisms, according to findings in the newly released and freely accessible web portal at www.europe-aliens.org and the DAISIE "Handbook of alien species in Europe" that is launched this week. Knowledge enables action Previous to the publication of the results of the DAISIE project, the number and impacts of harmful alien species (also called invasive alien species) in Europe has been underestimated, especially for species that do not damage agriculture, forestry or human health. The lack of knowledge has contributed to inaction in many European countries which is becoming increasingly disastrous for Europe's biodiversity, health and economy. Why do we need the information? Alien species may have a profound impact on the environment and society as they can act as vectors for new diseases, alter ecosystem processes, change biodiversity, disrupt cultural landscapes, reduce the value of land and water for human activities and cause other socio-economic consequences. Alien species are plants, animals and micro-organisms that have been moved by humans to new environments outside of the range they occupy naturally. Supporting qualified decisions Information in this week published DAISIE "Handbook of Alien Species in Europe" and the internet accessible knowledge base provides an important tool for managing the threat of biological invasion in Europe. Information in DAISIE can be used for documenting current invasions, predicting new invasions and preventing future invasions. Crucial information for planning measures for early detection, eradication and control methods is also provided to decision-makers, environmental planners, students and all concerned.

Will Europe at last unite to combat thousands of alien invaders? Europe's borders have been breached by thousands of plants and animal species from other parts of the world: from the American mink to the New Zealand flatworm. The invaders feed on, hybridise with, parasitise and out-compete native species.

Experts meet on need for new rules to govern world's fragile polar regions A new co-ordinated international set of rules to govern commercial and research activities in both of Earth's polar regions is urgently needed to reflect new environmental realities and to temper pressure building on these highly fragile ecosystems, according to several of the experts convening in Iceland for a UN-affiliated conference marking the International Polar Year.

Woody and aquatic plants pose greatest invasive threat to China Although China currently has fewer invasive woody plants than the United States, China's potential for invasion by nonnative trees and shrubs is high, according to an article in the May 2008 issue of BioScience. Alien plants attack using 'resource conservation' as weapon, researchers say One of the most serious and least understood threats to the world's ecosystems is the problem of invasive species-exotic plants, animals and other organisms that are brought into habitats and subsequently spread at a rapid rate, often replacing native species and reducing biodiversity.
