Conservation commission reviews preserve trail plan and warns logging will be limited by endangered-bat findings

The Conservation Commission received a detailed presentation on recreational-trails planning in the town preserve and an update on the state-led forest-management proposals for specific stands.

Staff described a heat map of user activity across roughly 30 miles of informal trails and said the planning team has prioritized five high‑priority reroute areas to protect vernal pools and other sensitive habitat. The presenter said the project goal is to reduce the number of informal user-created routes while keeping access where it is compatible with conservation goals.

"We can't have all these trails going through a lot of places that they should not go through," the presenter said, summarizing why the team is prioritizing reroutes and an interim trail system. The plan, as presented, distinguishes between officially endorsed trails and the many unofficial spurs visible on the heat map.

The presentation noted 34 vernal pools were identified and that core-protected-area buffers (the packet described 400‑ft and 200‑ft buffer zones) currently protect much of the preserve; presenters said about 60% of the preserve falls within those buffers and that some reroutes will be necessary to avoid the most productive pools.

Presenters explained the heat mapping was derived from a trail‑mapping app (packet cited user-tracking data) and recommended a mix of ground‑truthing, physical reroutes, signposting and targeted stewardship programs to discourage re-creation of closed paths. Commissioners asked how staff would close or block long‑standing rogue trails; the presenter and others emphasized long‑term education and low‑impact barriers rather than permanent removal, describing trail closure as difficult but doable with ongoing stewardship.

On forest management, staff summarized a state plan that identifies "stand 10" (described in the presentation as approximately 94 acres) as the first candidate for active silvicultural work including thinning and canopy treatment. The presenter said bat acoustic monitoring on stand 10 detected four bat species the packet described as endangered, which constrains when work can occur and will require specific seasonal timing. "They just finished that and they found four different bats in there. All of them are endangered," the presenter said, noting that seasonal limits mean operations would generally be timed for November through March.

Staff said the state will produce a stand-specific treatment plan by about September, that the plan will include the number and type of trees proposed for removal, and that the public will have an opportunity for input when that plan is released. The presenter emphasized the state approval process and noted that while the town will comment and the preserve committee will hold discussions, final approval for stand-level operations rests with state reviewers.

Public commenters and at least one commissioner expressed concern about erosion and the risk that lowest-bid contractors could cause drainage and compaction issues during logging operations. One commissioner said those factors documented in the packet were a major reason the commission should monitor the public-review process closely.

Next steps outlined at the meeting included additional ground‑truthing of proposed reroutes, a target to have the overall recreation-trails plan ready for more formal review by December, and stand-specific plans from the state expected this fall with subsequent public meetings and comment periods.
