Vascular plants (e.g. ferns) are invading around the world (image credit: Dawson et al. 2017).

Where are the most likely places for an invasive species to thrive? It turns out: islands and coastal regions. Researchers out of Durham University in the United Kingdom, as well as multiple other universities, recently published a paper detailing the global hot spots for invasive species. The most inundated: the Hawaiian Islands, New Zealand's North Island, and the Lesser Sunda Islands, Indonesia. These data help to inform mitigation strategies preventing further spread of invasive species that ultimately endanger local plants and animals.
