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 Ph.D. 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.
The fractional cover map produced by Mr Shiferaw not only provides information on the current distribution of Prosopis in the Afar Region, it also shows the percent cover of this alien tree across the invaded range. MORE
