PRIMARY school pupils have been getting their hands dirty by helping the Tees Valley Wildlife Trust with their wildflowers from waste project.

Youngsters from William Cassidi School, in Stillington, were involved in sowing a mix of wildflower seeds and plug plants to create a wildflower meadow as part of Stillington Forest Park.

All the plants used are native wildflowers that thrive in conditions created by using slag as a way of reducing the available nutrients in the soil.

The species used included greater knapwood, salad burnet and clustered bellflower, all flowers found in limestone meadows
