Gas Leaks and Trees
Decades of scientific research have shown that trees are adversely affected by gas that escapes from pipes under our streets and infiltrates the soil around tree roots. As the Tree Warden for the Town of Wellesley, the Natural Resources Commission is working to protect our public shade trees – and our entire tree canopy – from the devastating and costly effects of dozens of persistent gas leaks throughout the town.
Since 2018, the Natural Resources Commission has participated in the Multi-Town Gas Leaks Initiative – an informal group led by representatives of HEET, Mothers Out Front, Metropolitan Area Planning Council, and municipalities (including Wellesley). The initiative was launched to explore how towns in National Grid territory could work together to accelerate progress on gas leaks.
A sub-group on gas leaks and trees is working to provide resources on this topic and to organize further advocacy. If you are interested in participating, please contact Brandon Schmitt, email@example.com.
