“Join Etobicoke Master Gardeners and the Humber Arboretum for a free workshop & tour on Supporting Biodiversity: The Power of Wetlands and Ravines. Wetlands and ravines, no matter their size, classification, or condition, offer significant environmental benefits to both humans and wildlife. Discover their crucial role in our ecosystem, such as supporting biodiversity, improving water quality, aiding groundwater recharge, and providing flood control. Learn how individuals can contribute to the preservation of wetlands and ravines. Then, join a tour of the Humber Arboretum's 'Pond Project'. Remember to wear comfortable walking shoes and dress for the weather as you enjoy the beautiful gardens. “
