Cranberry bogs constructed in the early 20th century are still in production throughout Massachusetts, the #2 cranberry producer in the nation. However, one of the key challenges with traditional cranberry farming techniques is the capture and re-routing of free-flowing streams into carved-out irrigation canals, resulting in excessive sedimentation and obstacles for migrating herring, eel, and brook trout. Below is a summary of two of our cranberry farm restoration projects.
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).
Tidmarsh Farms River & Wetland Restoration
This project involved concept and final designs for 20,000 feet of stream channel restoration; 250 acres of fen and Atlantic white cedar bog restoration; sphagnum reintroduction; fish passage design; and the removal of a 20-foot-high dam in the headwaters. Over 3,000 pieces of large woody debris were incorporated into the stream channel restoration.
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.
