Cornwall boat owners in non-native sea species study
Boat owners in Cornwall are being asked to record marine life in a bid to detect non-native species.
Cornwall Wildlife Trust wants owners with access to pontoons to place a test panel into the sea for marine life to grow on it.
The trust said volunteers would contribute "vital scientific data" on non-native species.
Some foreign species may be a threat to marine life in the UK, the charity added.
Lisa Rennocks, from the trust, said: "People are being asked to deploy a small settlement panel in the sea for six to 10 weeks and then observe what begins to grow.
"The panels, which must be continuously submerged at all states of the tide, will provide an excellent insight into what is living in our seas."
