A black list to defend the local biotypes

On 9 September 2013, the Commission put forward a proposal for a new Regulation concerning measures to prevent and manage the introduction and spread of invasive alien species (IAS) in Europe. Illustrated in a press conference by the Commissioner for the Environment, was presented as " the classic example of a sector in which Europe gives you the best working," he continued Janez Potocnik " will help to protect biodiversity and aims to enable to concentrate its efforts on the most serious threats. "

A "fight " between different species. According to estimates on a European scale there are more than 12,000 alien species, so outside of their natural range, of which around 15% are invasive, or playing in the wild and its peoples have begun to spread, and it is scientifically proven significant adverse effects on biodiversity. It is clear the ecological problem that determines the spread of these species. Because of the risks arising from their arrival in Europe, such as the North American gray squirrel is supplanting the native red, to the extreme consequences of extinction of a species required in our ecosystem.

Issues related to invasive alien species. The first problem is economic in nature. In fact, over the last 20 years it is estimated that invasive alien species are at least cost Europe € 12 billion: in terms of public health, just think of the cost of health care related to the spread of allergies, for example, ragweed, or prevention put in place to eradicate the Asian tiger mosquito and control the spread, in terms of, finally, loss of production for companies, linked, for example, the effects of nutria ( Myocastor coypus Molina ), south American rodent imported from 1920, whose negative action on crops is well known along the streams and lake areas in the central - northern Italy.

The second, cross-border nature. The efforts of a Member State to eradicate an invasive species could be in vain if only confined to the national level. It therefore justifies action at EU level.

The proposal of the European Commission. L ' objective of the proposal is, therefore, to protect local biodiversity and ecosystems and to minimize their impact on human health and the economy, thereby contributing to the realization of the strategy on biodiversity in Europe by 2020. According to the proposed regulation, which will now be examined by Parliament and the Council, the Member States will contribute to compile a list of the main IAS and propose the species to be included in the black list of those banned by the EU ( species for which import will not be allowed, purchase, use, release, and / or sale). European Alien Species Information Network ( Easin ) of the Joint Research Centre, the in-house science service of the European Commission, will be the mechanism of information support of the new regulation. The Network was launched in September 2012 and is the first network of its kind in Europe, designed to improve access to data and information regarding alien species.

What do you have to do each Member State. According to the Commission's proposal, the action lines move around three actions: prevention, early warning and rapid response status and manage. Member States will be required to set up controls to prevent the intentional introduction of species of black list, however, will have to act and also to identify carriers of any accidental entry of invasive species, such as contaminants in cargo or in containers, taking corrective measures. The Regulation provides for a phase of early warning and rapid response, highlighted a kind of relevance to the EU is beginning to settle, the United States should immediately take the necessary measures for its eradication. The faster you play, the more long-term positive effects on the economy, society and the environment. This approach would require high initial investments, mainly to the United States, but considerable savings in the longer term, for society as a whole. If, however, already well established and widespread, the United States should take measures to minimize the damage of invasive species.

The next steps are the consideration by the Council and the European Parliament and the definition of the black list to which the Member States may use the European Network Easin ( http://easin.jrc.ec.europa.eu/ )

It is an action by the EU against the species, including plants, considered invasive. Each country should draw up its own list
