In 2004, The Green Legacy® was just a simple idea to plant 150,000 trees to celebrate the County's 150 year anniversary. That idea has grown to over one million trees planted in the County of Wellington by community partners, making it the largest municipal tree planting programme in North America!​  ​

The Green Legacy® has caught the attention of the United Nations. In 2010, the programme was recognized under the Billion Tree Campaign for their help in the fight against climate change.

The environment remains a very significant political, social and economic issue that involves all levels of government. Tree planting is an easy but effective way to improve the environment. The County fosters local initiative by providing trees free of charge to its residents and community groups.
