Schools Tree Day is observed in Australia every last Friday of July, where preschools, kindergartens, primary, and high schools participate in planting trees. This event, organized by the non-profit environmental organization Planet Ark, aims to address environmental issues in Australia by encouraging children to engage in activities that improve their surroundings. Schools are invited to register for participation, and they receive special lesson plans and resources focused on environmental protection. The main activity involves children learning how to plant seedlings and care for them, fostering a hands-on understanding of ecology. Schools Tree Day is part of the broader National Tree Day initiative, emphasizing the importance of tree planting in combating environmental challenges.
