Whitman's Pond Invasive Plant Mitigation

The use of systemic herbicides to manage invasive species carries the risk of collateral damage to native species like water lilies, creating a tension between ecological management and habitat preservation.

Requesting approval for minor vegetation maintenance to maintain billboard visibility.
Board response
The board suggested that instead of a simple amendment, the company should file a formal Notice of Intent (NOI) to include a long-term maintenance plan.
