"Rhos Street School is working towards achieving eco school status and projects such as these will help towards qualification," said Joanne Davies, a teacher at the school.

More than 30 species of shrubs and herbaceous plants have been chosen, and they will provide colour scent and a nectar source through spring, summer and early autumn.

"The next stage is to provide outdoor seating and what a perfect setting in which to deliver environmental education - the pupils own butterfly glade," said Mrs Davies.

"Full inclusive projects such as these where future sustainability is the responsibility of the schoolchildren really drives home a powerful conservation message and can only help in the development of environmental awareness that will hopefully stay with the pupils long after they have left Rhos Street School," she added.

Countryside warden Jim Kilpatrick stresses the importance of such schemes in helping to promote local biodiversity.

"The schoolchildren will be taught how to identify the butterfly species that are likely to take advantage of the rich nectar source and how to maintain the area in an ideal condition.

"Denbighshire Countryside Service is becoming increasingly involved in the development of outdoor classrooms and although funding for such projects is still difficult to find, a partnership approach with everybody pulling their weight can lead to innovative and productive schemes."
