In the eye of the invasive species storm
17th September 2014 – Last weekend I experienced first-hand the impacts that invasive species can have. While carrying out research on an infestation of Opuntia Stricta in Laikipia, I felt something lodge itself in my eye. The following day I visited a specialist, as efforts to wash the thorn out of my eye had been…
CABI releases rust fungus to control invasive weed, Himalayan balsam
26 August 2014 – From today, not-for-profit research organization, CABI, will be releasing a rust fungus at locations in Berkshire, Cornwall and Middlesex as part of field trials to control the non-native, invasive weed Himalayan balsam (Impatiens glandulifera) using natural means. Himalayan balsam has rapidly become one of the UK’s most widespread invasive weeds, colonizing…

Green Invasion: Destroying Livelihoods in Africa [Video]
CABI, together with Tmax Productions, have produced a video called the ‘Green Invasion – Destroying Livelihoods in Africa.” The short film (approx. 7mins long) details how invasive weeds are impacting on the lives of rural communities in East Africa. Although a large number of non-native species have become invasive in the region, this film focusses on…
Himalayan Balsam and its impact on UK invertebrates
Himalayan balsam is one of the UK’s most widespread invasive weed species, colonising river banks, wasteland, damp woodlands, roadways and railways. Research by CABI scientists has shown local invertebrate biodiversity is negatively affected by the presence of Himalayan balsam. This leads to fragmented, destabilised ecosystems, which has serious consequences on processes and functioning, and complicates…
The urgent need for evidence based policy in invasive species management
Hundreds of invasive species experts gathered last week, 23-27 October, in Qingdao China at the 2nd International Congress on Biological Invasions. High on the agenda was how policy makers can respond to the accelerating risk posed by invasive species as international trade increases and climate change opens up new opportunities for invasion. In a session…
