With all that travelling (first fieldwork in Sweden/Norway, then the conference in Florida), I did not have time yet to announce the good news: we just got a paper published in Alpine Botany, reviewing the current knowledge on plant invasions in the alpine zone, above the tree line.

Western European species like the red clover (Trifolium pratense) here are often listed as non-native species in mountain regions.

It was a fruitful collaboration from our network, (MIREN, the Mountain Invasion Research Network), joining forces with everybody that knows something about plant invasion in the highest mountains.

Although the alpine zone has been harder for invasives to access than most places, human structures like trails are often an easy gateway for the invaders to get up there. Picture from Abisko, Swedish Lapland.

You can read all about it through my post on the blog from the Mountain Research Initiative.
