“The best time to plant a tree was twenty years ago. The second-best time is now.”

Great Lakes St. Lawrence Trees Initiative

A regional effort with the goal of planting 250 million trees by 2033.

Why trees?
• Trees clean the air by storing carbon and removing other pollutants.
• Trees can save lives by improving cardiovascular health, supporting mental health, and reducing urban heat effects.
• Trees absorb stormwater to help improve the health of streams, lakes and drinking water.
• Trees provide habitat for other plants and wildlife.
• Trees create recreational landscapes, economic benefits and jobs.

Why the Great Lakes St. Lawrence Region?

Tree planting is a major opportunity for the region and its people to improve the quality of life while offering a high “return on investment.”
Over the next decade, the Great Lakes St. Lawrence Governors & Premiers (GSGP) will work with the region’s eight US States and two Canadian Provinces, federal governments, corporations, cities and other institutions to achieve this goal.
