Climate change to trigger UK invasive ‘sleeper species’ into action

Harmless non-native species currently present in the UK could become a threat as temperatures rise as a result of climate change, a group of MPs has been warned.

The remarks were made this morning by DEFRA’s biosecurity minister Lord Gardiner, as part of an ongoing inquiry into the threat of invasive species in freshwater environments, launched by the House of Commons Environmental Audit Committee (EAC).

Gardiner said that while gardens in Great Britain were full of non natives such as rhododendrons that did not present any threat to other native species, plants such as the black locust tree, the tree of heaven and water weeds like bacopa caroliniana and cabomba, known as“sleeper species”, will likely present issues in the future due to a warming climate.
