In all, more than 1,200 trees will be planted in East Yorkshire this spring as part of the scheme, adding to over 160,000 planted across the UK. Schools had a choice of packs from hedge tree species, copse species or seeds.

The initiatives are courtesy of the Woodland Trust's ground-breaking Tree for All campaign, launched in September 2004. It is the largest children's tree planting initiative the UK has seen and will see more than 12 million trees planted by one million children by 2009, inspiring today's youngsters to engage with nature and become environmental custodians of the future.

Paul Bunton, of the Woodland Trust, said: "Because of modern lifestyles, many children are growing up with little connection with their natural environment. Tree For All is about inspiring young people to become future guardians of the natural environment and to encourage people to become more in touch with nature, increasing their understanding and enjoyment of woodland."
