Tree Line USA, a partnership between the Arbor Day Foundation and the National Association of State Foresters, recognizes public and private utilities for pursuing best practices that protect and cultivate America's urban tree canopy. In addition, Tree Line USA promotes delivering safe and reliable electricity while maintaining healthy community forests.

"Trees are essential to creating more urban green spaces in communities across the United States," said Dan Lambe, chief executive of the Arbor Day Foundation. "In addition, they provide important benefits to residents, including clean air, clean water, and vital tree shade. Service providers like Ameren demonstrate how easily trees and utilities can co-exist for the benefit of communities and residents."

As a result of properly pruned and maintained trees, customers benefit from increased reliability of service because those trees will have healthier root systems, less structural weakness, and ultimately result in fewer downed lines during storms.

"Ameren has a robust year-round tree trimming and vegetation management program that helps ensure trees and limbs are clear of electrical equipment to maintain reliability," said?Amy Werner, manager, Vegetation, Ameren Missouri.

"We know homeowners don't want to lose mature trees in their yards because they are growing too close to the power line," said Richard Johnson, manager, Vegetation, Ameren Illinois. "We are reminding our communities how to be proactive and select the right tree and the right location for it. This will help ensure it can grow there for decades to come without posing any risk to your electric service."

Plan Before You Plant

Make sure your trees are not planted under power lines, too close to utility poles or around any electrical equipment. Avoid these common mistakes:

  • Planting a sapling that grows to be very large near a power line.
  • Planting trees and shrubs too close to a pad-mounted transformer.
  • Planting trees and shrubs that block access to poles and electrical equipment.
  • Not calling 811 to have buried utilities marked on your property before digging.

Ameren achieved the Tree Line USA recognition by meeting five program standards: quality tree care, annual worker training, tree planting and public education, a formal tree-based energy conservation, and a sponsorship of or participation in an Arbor Day celebration.
