Woody weeds in East Africa
Many exotic trees and shrubs have been introduced into Africa and become destructive invasive species. They’re reducing native biodiversity and limiting the livelihoods of those that live in rural communities. CABI is trying to mitigate these impacts in East Africa by generating and sharing knowledge on their effects and finding ways that they can be controlled.
Finding a biocontrol agent for Crassula
Crassula helmsii is an invasive water weed that dominates still or slow-flowing water bodies. It’s spreading throughout the UK and has the potential to out-compete native flora and reduce oxygen levels by forming dense mats. Management of this species can be very challenging, with chemical and mechanical options limited. CABI were commissioned by the UK government to investigate the possibility of controlling the weed using biological control. This includes testing by our scientists to ensure that any potential agent is safe for release.
