Czech Republic teeming with invasive species

The Czech Republic is high on a list of EU states affected by invasive species, i.e. plants and animals not native to the continent which are upsetting the natural eco-balance. According to a survey commissioned by the French daily Le Soir, the Czech Republic is the fourth worst affected country in the 27 member block, after Britain, Belgium and France. The economic losses caused by invasive species across the EU are said to amount to 12 billion euros a year. There are currently estimated to be some 2,000 invasive species in the Czech Republic.
