Prioritising management of established non-native species on Caribbean UKOTs

Invasive alien species are identified as one of the main drivers of biodiversity loss worldwide. They are a particularly significant problem for the UK Overseas Territories (UKOTs) because they comprise mostly small, isolated islands and have high levels of rare and endemic biodiversity.

Professor Helen Roy, a co-chair of the IPBES Invasive alien species assessment, and Dr David Roy, both of the UK Centre for Ecology & Hydrology, were among international experts taking part in workshops on two UKOTs in the Caribbean in January and February 2020...

Environmental Audit Committee calls on citizen scientists to tackle threat from invasive species

Last week, the Environmental Audit Committee (EAC) published a report that calls on an 'army' of citizens to tackle the growing threat from invasive species, estimated to cost Britain’s economy £1.8 billion a year. Centre for Ecology & Hydrology (CEH) ecologist, Professor Helen Roy, tells us more about her invitation to give evidence to the EAC’s inquiry on the topic…

Predicting the threat from invasive non-native species in British Overseas Territories

Last month, I led a team of ecologists who met in St Helena, a volcanic tropical island in the South Atlantic Ocean, to collaborate with invasive species experts on the mid and south Atlantic UK Overseas Territories. Together we are working to predict and prioritise those non-native plant and animal species most likely to present a threat to existing ecosystems, human health and the economy on the island, as well as developing Pathway Action Plans to inform the already incredible work of the local biosecurity teams.

Predictions and priorities to prevent new invasive non-native species arrivals

CEH ecologists are contributing to international efforts to strengthen biosecurity in the British Indian Ocean Territory. Prof Helen Roy explains more...

A magical and remote atoll, the British Indian Ocean Territory (BIOT) comprises extensive coral reefs and unique terrestrial habitats. Not only does BIOT host the Indian Ocean’s largest breeding colonies of the red-footed booby Sula sula, but also high densities of coconut crabs and endangered hawksbill and green turtles.

Caribbean workshop focuses on invasive alien species

Professor Helen Roy reports back from a workshop that she led alongside Centre for Ecology & Hydrology colleagues Jodey Peyton and Dr Oli Pescott on Grand Cayman last week. The event's purpose was to determine which invasive alien species were likely to arrive, establish and impact on biodiversity, ecosystems, human health and the economy across the Caribbean UK Overseas Territories within the next 10 years.
