Signal crayfish threat

Heysham Obs
Great - presumably someone using Middleton model boat pond as a "save the tadpoles" dumping ground or a misguided idea of biodiversity has almost certainly introduced signal crayfish.  Bring back the terrapins!  Lots of tiny immatures found today does not augur well for the future of this pond and its dragonfly population for this highly invasive and difficult to control species
