Maine’s Forests Face a New Threat from a Power Line Plan
A plan approved last November by Maine’s Department of Environmental Protection (DEP) promises to protect 50,000 acres of forest as a buffer for a new power line that will stretch from the Quebec border to central Maine. The plan says half of this area must be managed as “mature forest habitat” and will be held in a state conservation easement.
The Weak Definition of “Mature Forest Habitat”
- Current threshold: a stand that reaches 50 feet in height, roughly 50 years old.
- Missing elements: large trees for nesting/denning and the complex vegetation layers many forest birds depend on.
Because most land outside stream buffers is open to standard sustainable logging, trees that meet this low maturity threshold can be harvested as soon as they are 50 feet tall. The plan allows clear‑cutting of thousands of acres every decade, which means that the net gain in mature forest is likely to be zero.
Additional Concerns
| Issue | Impact |
|---|---|
| Weyerhaeuser’s logging | The company can cut more heavily nearby to offset restrictions inside the protected zone, negating overall forest health gains. |
| Delayed maturity | Some stands may be cut before the 50 % mature goal is met, extending the time to reach that target by about forty years. |
| Ecological benefits | The delay reduces the intended ecological benefits of the plan. |
Proposed Revisions by Environmental Groups
- Stricter definition – require a minimum number of large‑diameter trees.
- Clear‑cut limits – restrict the size and spread of clear‑cut patches to mimic natural disturbances.
- Ban on cutting mature stands – prohibit cutting any stand that meets the revised maturity criteria until the 50 % target is achieved.
Only by adopting these adjustments can the plan truly protect Maine’s mature forests and preserve wildlife corridors as intended.
