The Woodland Trust has teamed up with Yellow Pages and The Directory Recycling scheme to launch a fundraising and recycling campaign in schools.
The Yellow Woods Challenge, which links Yellow Pages recycling with educating young people on the environment, will run in more than 1,000 schools across the UK to raise funds for the trust.
The new initiative will reward schools with environmental education materials and cash prizes. For every pound awarded to schools in prize money, £1 will be donated by Yellow Pages to the trust to help keep native woodland alive.
Schools will compete against each other to win cash prizes for collecting the most old directories per pupil. They can win up to £2,000 to improve their school's environment as well as woodland certificates, videos and CD-Roms.
All participating schools will receive a teachers' toolkit containing posters and an activity pack to bring the challenge to life.
