We had the good chance to see a short but informative video on Euronews yesterday that discussed invasive species in Europe.
It highlighted the problems that Spanish farmers are having with such exotic species as zebra mussels. These mussels reproduce very quickly and are a huge pest. They block irrigation pipes, as well as causing problems in reducing the quality of the water. The video also highlights the economic implications that these invasive species can cause, such as the example given with the grey squirrels in Europe. These squirrels like to chew away at the bark of trees that could be considered for timber production. As a result of the damage done by the squirrels these trees are deemed worthless.
If you’re interested in learning more, there is alo a very good database/website dedicated to invasive species in Europe called DAISIE (Delivering Alien Invasive Species Inventories for Europe).
