Pupils from Belper School have been helping Derbyshire Wildlife Trust look after a Belper wildlife site.
The pupils, aged 13 to 16, have been working at Alton Manor Local Wildlife Site near the school.
They have been carrying out the work, with funding from Western Power Distribution, to gain a John Muir Award.
Jill Leheup, Derbyshire Wildlife Trust’s People Engagement Officer, said: “The project has been a great experience for the pupils and they really seem to have enjoyed it.
“They have been able to discover a local wildlife habitat and learn what fun it can be to look after it. Local residents have been coming up to us while we’ve been working to tell the youngsters how much they appreciate their efforts. We’re really grateful to Western Power for supporting this work.”
The award is administered by the John Muir Trust, named after the pioneering Scots-born American conservationist.
It encourages awareness of and responsibility for the natural world and sets participants four challenges – discover, explore, conserve and share.
The pupils have been conducting wildlife surveys in the grassland and other habitats and removing Himalayan balsam and brambles from the site. They finished by creating a booklet about their visit.
