Tree Planting Challenge is one of our flagship programmes. It is a unique environmental activity that combines tree-planting, hiking and a test of your endurance. Since 2005, 83,000 seedlings were planted on the slopes in various country parks, by more than 9,000 participants in the past 10 years. We now invite all nature lovers to experience the challenge of tree-planting work and spread the message to "Save Trees, Conserve Nature". Let’s take action to reduce our carbon footprint,stop global warming, and learn more about the impact of climate change.
