71 mammal species have apparently invaded Europe since neolithic times, including the raccoon which is now present in Sweden. Whilst colonisation of new areas can be a natural response of animals to changes in their original habitat, many of these species have been introduced by humans, either deliberately as a food source or accidently if pets escape.
According to a report in Zoology journal 58 of these species directly harm humans or the environment, for example by threatening native biodiversity.
Pyrenean Desman (Galemys pyrenaicus)… An aquatic insectivore that is closely related to moles. Classified as ‘vulnerable’ by the IUCN these creatures are hard to spot due to their nocturnal and aquatic lifestyle. Once existing across the mountain ranges of western Europe, this animal now only lives in a national park in Catalonia. There are only 2 species of this unusual family remaining: this, and the Russian Desman (Desmana moschata).
Their demise is thought to be due to their loss of habitat. Hopefully further research by scientists from the University of Barcelona will help to save these amazing animals!
