TEC’s Tennessee Tree Day is an annual, family-friendly event that engages thousands of volunteers across the state in planting native tree seedlings. By partnering with the Tennessee Division of Forestry and various nurseries, we distribute bare-root native trees to Tennessee residents through our vast network of dedicated volunteers and local businesses. Since our initiative began in 2007, we’ve mobilized over 100,000 residents to plant more than one million native trees —an effort that not only significantly enhances the tree canopy and promotes sustainability but also provides critical ecosystem services, such as purifying air, filtering stormwater, and creating wildlife habitat.
