Invasive alien plant species form a serious challenge in many areas across Europe, where their rapid spread can severely impact ecosystems. A natural solution may be present in the form of (natural) grazing, where herbivores can suppress or even eliminate the proliferation of invasive species. In this blog, we look in more detail at the case of Amorpha fruticosa, or false indigo-bush, which causes major problems, particularly in the Danube basin, and for which extensive grazing can offer a solution.
