CABI scientists have revealed the massive ecological and economic impacts that the invasive alien tree Prosopis juliflora has had across the Afar Region of north eastern Ethiopia.

Dr Urs Schaffner, who is supervising lead author Mr Hailu Shiferaw for his PhD studies, contributed to the Science of The Total Environment published research which shows that the devastating Prosopis was a major reason for losses in annual ecosystem service values in Afar Region estimated at US $602 million in just 31 years.

CABI scientists have helped map the ferocious speed and probable cause of a devastating spread of the invasive alien tree Prosopis juliflora (Swartz DC) across an area equivalent to half of neighbouring Djibouti in the Afar Region of north eastern Ethiopia.

Dr Urs Schaffner, who is supervising lead author Hailu Shiferaw for his PhD studies, contributed to the Scientific Reports published paper ‘Modelling the current fractional cover of an invasive alien plant and drivers of its invasion in a dryland ecosystem’, which shows that the Prosopis invaded 1.2 million ha of grassland/shrubland in just 35 years.

CABI scientists are leading the fight to control one of the UK’s most invasive weeds – Himalayan balsam

hb-2019story

CABI experts in the field of classical biological control are leading the fight to manage one of the UK’s most invasive weeds – Himalayan balsam – thanks to the nationwide release of the rust fungus Puccinia komarovii var. glanduliferae.

Dr Carol Ellison, who has over 30 years’ experience of the biological control of weeds using fungal pathogens, told a specially convened NERC-sponsored workshop on Himalayan Balsam at Royal Holloway, University of London, the rust release programme is progressing well but new strains are required in order to achieve countrywide control.
