Researchers in the Isle of Man are to study the island's wild wallaby population which is thought to be more than 100, according to the Manx Wildlife Trust.

The animals, which are native to Australia and Tasmania, have populated the Curraghs since a pair escaped from a wildlife park in the 1960s.

The project will use a series of hidden cameras and hopes to establish their populations and asses the impact on the environment.

Manx Wildlife Trust director Duncan Bridges said: "Their numbers are gradually increasing because they have no predators or competitors."
