Tiny mite could prove a ‘mighty’ weapon in the fight against one of the UK’s most invasive weeds

CABI scientists are stepping up the fight against one of the UK’s most invasive non-native aquatic weeds. Approval has been given for the release of a novel biological control agent – the mite, Aculuscrassulae – to assess its ability in the real-world environment to suppress Australian swamp stonecrop (Crassula helmsii), also known as New Zealand pigmyweed. This…

The economic impact of invasive species on Great Britain revealed

A report, written by CABI for the Scottish government, Defra and the Welsh Assembly Government, estimates the cost of invasive non-native species to Great Britain in unprecedented detail. Invasive non-native species can have wide-ranging effects on biodiversity, crop production and people’s livelihoods. A better understanding of the negative impacts of invasive species will help to…
