FAQ – Are there any other examples of where non-native species have been used to control other non-native species in the UK?

Yes. There is an example regarding an animal species. The non-native predatory beetle, Rhizophagus grandis, was released under licence in the mid 1980’s to tackle the invasive non-native spruce bark beetle (Dendroctonus micans). The predator is now well established and follows the spruce bark beetle as it spreads, keeping the latter under control. Occasional releases are made where distribution of the spruce bark beetle ‘jumps’ eg. is accidentally transported some distance. This is an example of natural, or biological control as a non-native species was deliberately introduced in order to tackle another invasive non-native species.
