Marstons Mills Cranberry Bog Eco-Restoration Project

Comprehensive Study Area

Draft 9/24/2026

The Comprehensive Study Area (CSA) is a 17-acre area within the Marstons Mills Cranberry Bog Eco-Restoration Project. Through a design-build approach, BCWC and its partners are adapting designs during construction to compare nitrogen-removal treatments and their costs. Long-term monitoring, an outdoor classroom, and onsite facilities will connect the experiments with science education and outreach.

Nitrogen removal

Promising results from small experimental systems called mesocosms are informing larger, side-by-side field scale trials of different wetland types. Pumped nitrogen-rich groundwater will provide comparable concentrations at each treatment-cell inlet. Lawn fertigation trials will also demonstrate an approach homeowners could use to reduce their nitrogen impact. The study will examine how treatment performance and construction costs compare, helping guide future restoration decisions.


Vegetation

Atlantic white cedar plantings and sphagnum relocation are also part of the work. Living Observatory will investigate how planting conditions affect cedar recruitment, survival, and growth. The construction team will be preserving and relocating existing sphagnum to help insulate disturbed peat and to reestablish vegetation after construction. Young cedars will be planted and seeds sown on upland islands, including in relocated sphagnum.
