Azolla weevil used to tackle invasive plant in Pembrokeshire

A beetle is being used to tackle an invasive plant species in a Pembrokeshire nature reserve.

The Azolla weevil, a herbivorous beetle, was released in June 2024 by the Four Rivers for LIFE Project onto Natural Resources Wales’ (NRW) Llangloffan Fen National Nature Reserve (NNR) near Fishguard.

The beetle is being used to help control and eradicate the Azolla plant, which is dominating parts of the reserve and the nearby Cleddau River.
