Current distribution of the invasive weed, Mimosa diplotricha, was based on roadside surveys, literature reviews and herbarium data.
CABI scientists have conducted research which is calling for an urgent integrated management strategy, including biological control, to fight the invasive weed Mimosa diplotricha which is threatening livelihoods in eastern and southern Africa.
