New woodland habitat created for protected Great Crested Newts

National Grid has successfully completed the first phase of its environmental enhancement work at Pelham Substation in Hertforfshire, planting approximately 140 native saplings to create a dedicated habitat for Great Crested Newts, a protected species known to inhabit the area.

Located to the southwest of the substation, the new woodland spans 5,920 square feet and has been designed to blend in with the surrounding landscape. The habitat features a diverse selection of native trees including Oak, Mountain Ash, and Birch—each selected for their ability to naturally thrive around Stocking Pelham village and provide a supportive environment for local wildlife. 

The enhancements were designed with Natural England, ensuring that every aspect adhered to best practices for biodiversity conservation. Timing was also a crucial factor, with National Grid’s environmental team completing the planting before the end of the Great Crested Newts' hibernation period. 

This initiative forms part of National Grid's broader commitment to delivering a minimum 10% Environmental Net Gain on all construction projects. Additional woodland planting is scheduled for late 2025, with plans for two recreational ponds to be created by 2026 that will be accessible to the local community. These enhancements aim to support local biodiversity while providing new amenities for Stocking Pelham residents. We’re excited to see these green spaces flourish into natural environments where local wildlife can thrive alongside our essential infrastructure.
