Global expansion of Cytisus scoparius (L.) Link over 200 years.

ABSTRACT

Cytisus scoparius (L.) Link, commonly referred to as Scotch broom, is a Mediterranean shrub capable of thriving in a variety of ecosystems that has invaded every habitable continent on Earth. Our research presents a timeline and estimated rate of expansion from 1816 to 2016. We then model its expected range over the next 70 years, highlighting the need for investigation into its expansion mechanisms and the establishment of monitoring programs.
