Each year, The Tree Council’s member organisations such as voluntary bodies and local authorities, up to 200 schools and community groups, their 6,000 strong network of volunteer Tree Wardens and many others, support the initiative by setting up fun, worthwhile and accessible events, inspiring upward of a quarter of a million people to get their hands dirty and together plant trees.
