Yes, Japanese knotweed is a real headache for householders. We also have invasive species from the animal kingdom, which can be a real menace, such as the killer shrimp. This was discovered in waters off Cardiff Bay and in Eglwys Nunydd reservoir in Port Talbot in 2010. Now, the biosecurity sector has been monitoring the situation since then. I wondered if you had any updates on the current level of menace posed by the killer shrimps.
