The start of 2019 brought sad news when George, the last tree snail of his kind (Achatinella apexfulva) died on New Years Day. His death highlights the plight of Hawaiian snails and epitomises the rapid decline of biodiversity on the Hawaiian Islands.

CABI has published one of the most complete and current datasets on Invasive Alien Plants (IAP) in East and Southern Africa. This extraordinary dataset is already being translated into new research findings and conservation action on the ground.

Invasive alien species should not be used in restoring degraded landscapes as their costs outweigh their benefits, experts say.
Invasive alien species, according to the Convention on Biological Diversity, are plants, animals and other organisms that are non-native to an ecosystem, and may adversely affect human health and the environment, including decline or elimination of native species.

Invasive alien plants contribute to land degradation by forming vast unproductive monocultures. These invasions have a negative impact on biodiversity, water resources, crop and pasture production, human and animal health, and as such undermine Africa’s ability to achieve its Sustainable Development Goals. Landscapes degraded as a result of unsustainable land-use practices are also more likely to be invaded by invasive plant species, making any attempts at restoration considerably more difficult. As such it is imperative that invasive species management forms an integral part of any attempt at landscape restoration. By actively removing invasive species, followed by restoration, livelihood outcomes will be enhanced across the continent.
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 follows carefully controlled laboratory testing to ensure the safe, controlled release of the mite in the UK.
New research announced today by scientists at CABI confirms that a recently introduced crop-destroying armyworm caterpillar is now spreading rapidly across Mainland Africa and could spread to tropical Asia and the Mediterranean in the next few years, becoming a major threat to agricultural trade worldwide.
Invasions from non-native plants, animals and pathogens threaten the economies of the world’s poorest nations, according to a new study.
The study, published in Nature Communications (‘Global threats from invasive alien species in the twenty-first century and national response capacities’) found that one-sixth of the world’s land is highly vulnerable to invasion, including substantial areas in developing countries and global biodiversity hotspots.
