Not even freezing cold stops alien species in high altitudes
Date:3/4/2014

f the alpine nature probably results from a lower resistance," says Jonas Lembrechts. Alpine plants in the far north are not prepared for the invasion of competitive species from the valley.

"Most likely, these alien lowland species are becoming increasingly successful in alpine terrain due to the warmer weather we have experienced in the past decades," says Ann Milbau. "Climate warming and increasing human disturbances in high latitude mountain regions may further increase the pressure from introduced species in the coming years."

The scientists conclude that mountaineers and hikers should be aware that they carry undesired co-travellers under their feet when they explore pristine areas. To clean shoes and other equipment before before the trip is a good way to preserve the vegetation in the areas they plan to visit.
