Professor Kristine Bakke Westergaard found in a new study that warmer temperatures and more tourists make it easier for non-native plants and animals to get a foothold in far northerly outposts. (Nina Tveter / NTNU via SWNS)

In recent years, a surprisingly large number of alien species have managed to flourish in Svalbard, Norway. In 2024, common meadow rue, Thalictrum flavum, was identified for the first time in Svalbard, in full bloom on a nutrient-rich slope in Barentsburg. (Kristine Bakke Westergaard / NTNU via SWNS)

The slope below the old barn and farm buildings in Longyearbyen is very nutrient-rich after manure and food scraps were dumped there for years. It’s a great place where new alien species can get established. (Kristine Bakke Westergaard / NTNU via SWNS)
