They have embarked on a back-breaking campaign to cut back gorse bushes at an Anglesey beauty spot.

The Breakwater Park Country Park is one of the few areas in the UK where you can find the vividly coloured silver studded blue butterfly.

Their numbers have declined dramatically over the past 30 years but now they're making a comeback on Anglesey thanks to the team's efforts.

All the labour has been supplied free of charge by young people aged between 16 and 18 who are under the supervision of the Youth Justice Services Gwynedd/Mon. The members of the team have been sentenced by the courts to carry out unpaid work that is beneficial to the community.

The project is being organised by Community Justice Interventions Wales who work in partnership with the North Wales Probation Area and the Youth Justice Services.

Experts say the gorse clearance will be invaluable because the butterflies are weak fliers and tall vegetation prevents them colonising suitable areas.

Gareth Evans, a Countryside Warden with the Isle of Anglesey County Council, was extremely grateful for the group's help.

He explained: "This butterfly is rare in this area, there are a few on South Stack on the other side of the mountain and on the Great Orme, in Llandudno.

"Their preferred habitat is heather and heathland. They love areas that have just been cleared.

"The gorse has started taking over here which is why it is being cut back to make more room for the heather to grow.

"We are clearing different patches of land in a five year rotation programme. We are creating a patchwork of different habitats to support a variety of species, including the silver studded blue."
