Tidmarsh Farms River & Wetland Restoration
Holistic ecological restoration of cranberry bogs to native stream and wetland ecosystems was pioneered by Inter-Fluve through the Tidmarsh Farms project. Over 20,000 feet of stream channel and 250 acres of fen and Atlantic white cedar swamp were restored, improving climate change resiliency. The project used 3,000+ pieces of large wood to improve habitat for fish and aquatic organisms, and involved removal of a 20-foot-high dam. The landowners’ Living Observatory project unites private, public and educational institutions from 10 universities to perform long-term monitoring and is partnering with Mass Audubon following their purchase of the site for a wildlife sanctuary.
The project received a 2018 American Council of Engineering Companies (ACEC) Silver Award and was also a winner of one of the Environment Business Journals (EBJ’s) 2017 Business Achievement Awards for Natural Resource Management. The Tidmarsh project was also highlighted in the New York Times in June 2017 (link), and in Landscape Architecture in January 2018 (PDF of article here).
Listen to Inter-Fluve’s Nick Nelson and others discuss aquatic restoration projects (including cranberry bog restoration) on Cape Cod and how these projects will contribute to coastal resiliency and habitat diversity. The program aired on the NPR station for the Cape, Coast & Islands (WCAI).
In addition to the restoration of red maple swamp, fen and sand plains, over 20,000 Atlantic white cedar tree seeds were collected, propagated and later transplanted as part of a goal to establish only plants indigenous to southeastern Massachusetts and the Tidmarsh site itself.

Eel River Headwaters Restoration & Sawmill Dam Removals
This project involved reclamation of 40 acres of cranberry bog by recreating pre-agriculture hydrology and restoring the area to native Atlantic white cedar and sphagnum dominated swamp; restoration of over 8,000 feet of stream channel; removal of a 15-ft high stone dam; installation and fencing for 17,000 Atlantic white cedar trees; and installation of 1,000 pieces of large wood in the stream for fish habitat. Inter-Fluve received a Coastal America Award presented to the project designers and partners by the Assistant Secretary of the Interior.
