A concern for the commission was the chronic issue of overbank flow from Smiling Pool, largely attributed to persistent beaver activity. The beavers have manipulated the original water control features, namely the flashboards installed during the pool’s construction around 1970, rendering them ineffective. This manipulation has led to water overflowing, causing erosion of nearby trails and creating hazardous conditions, particularly affecting Main Street. In response, the commission proposed lowering the water level in Smiling Pool to convert it into a flood storage basin. This proposal aims to alleviate flooding issues and prevent further trail erosion, which has been a growing concern for local residents and conservationists alike.

The commission also examined the Laughing Brook Wildlife Sanctuary Restoration Invasive Plant Management project. Naomi Valentine from SWCA Environmental Consultants, representing Mass Audubon, outlined the ecological restoration project, which spans approximately 150 acres. The project aims to improve forest health and habitat for rare species through invasive plant management, specifically targeting species like oriental bittersweet and autumn olive. Valentine explained the use of systemic herbicides such as glyphosate and triclopyr, emphasizing targeted application techniques to minimize environmental impact and prevent chemical runoff into water sources.

The removal of a small pavilion and flashboards from an existing weir structure at the Smiling Pool was another focal point of the discussion. The pavilion’s removal is part of efforts to prevent bank erosion, while the flashboards’ removal aims to address water level control within the wetland area. The commission emphasized coordination with Mass Wildlife and the Natural Heritage and Endangered Species program to ensure the project’s alignment with broader conservation efforts.

Concerns were raised about the proposed use of fire as a management tool for invasive species and forest restoration. A state official’s letter questioned the area’s historical fire-proneness. The commission clarified that fire was not part of the current invasive management strategy, which instead focuses on mechanical and chemical controls. This approach is intended to effectively target invasive plant root systems, addressing challenges associated with mechanical removal methods that can inadvertently promote further growth.

In addition to the sanctuary project, the commission addressed other property-related issues, notably potential wetland violations and unauthorized activities on conservation land. A site inspection was scheduled for a property on Scantic Road, where concerns about wetland border violations were discussed. The commission planned to issue a violation notice if any discrepancies were found during the inspection.

The meeting also highlighted ongoing issues at South Bridge Estates and the Forbes property, both flagged for potential wetland violations. The commission discussed the necessity of sending certified notifications to abutters and hiring a wetland specialist to assess the untouched resource areas. Concerns were raised about unauthorized land clearing activities and the removal of barriers, prompting the commission to emphasize the enforcement of wetland protection guidelines.

A notable development involved the proposal to appoint two individuals, Eric and Joe, as full voting members of the commission. The selectmen expressed openness to this proposal, provided the individuals attend an upcoming meeting for in-person consideration. This potential expansion of commission membership could bolster the commission’s capacity to address the various environmental challenges discussed during the meeting.

The commission also reflected on the impact of a previous spongy moth outbreak, which devastated oak trees in the area, contributing to safety concerns and the proliferation of invasive plants. This highlighted the urgency of implementing effective management practices to restore native species and counteract the negative effects of past pest outbreaks.
