As the Member knows, the trial site in Swansea is located in his constituency at Llansamlet, along a 450m section of the Nant Bran stream. Care has to be taken, of course, when releasing another non-native species to control an existing non-native species, as the Australians will tell you, given the plagues of frogs that they quite often—biblical, almost, plagues of frogs that they experience there. So, this has been done in a controlled way. We hope, of course, that this will be a successful way of controlling knotweed by a natural predator without, of course, that creating imbalance elsewhere in terms of biodiversity.
