Habitat Restoration Projects

Habitat restoration on Silver Creek has been a priority of The Nature Conservancy for more than forty years. Early efforts focused on working with landowners to fence cattle out of the stream, followed by extensive and ongoing riparian vegetation and wetland plantings. Without this long‑term commitment—and the creation of thousands of acres of conservation easements—Silver Creek would look very different today.

Despite these successes, one of the most persistent and challenging habitat issues on Silver Creek remains siltation. This problem is well documented. For decades, Silver Creek has served as a repository for legacy sediment resulting from aging agricultural practices and airborne dust. Because the creek is slow‑moving, sediment accumulates in some reaches and does not naturally flush out. Without intervention, it could take hundreds of years for this material to move through the system on its own.

Many landowners have taken significant steps—and incurred substantial personal expense—to remove accumulated sediment and restore riparian habitat to a more natural, functioning condition. In fact, two Silver Creek Alliance board members have undertaken major sediment‑removal projects on their own properties. However, not all landowners have the financial capacity to address these challenges independently, even though they share the goal of restoring habitat and revitalizing the fishery.

This is where support from the Silver Creek Alliance can make a meaningful difference. Financial assistance helps landowners undertake restoration projects that benefit not only their individual properties, but the entire Silver Creek fishery and the public who enjoy it. Recent sediment‑removal efforts have demonstrated exceptionally positive results. One notable example is the Kilpatrick/Purdy Pond Project—arguably one of the largest spring‑creek sediment removal projects ever attempted. Just four years after completion, the system has rebounded so thoroughly that it is difficult to tell any large‑scale work ever occurred. The fishery has responded remarkably well, and enhanced wetlands and riparian plantings have restored the area to a thriving, fully functioning ecosystem.

Sediment removal and habitat restoration on Silver Creek require site‑specific approaches. Each reach of water presents unique challenges, costs, and regulatory considerations.

To guide these efforts, sediment inventories and data collection have been conducted over the past six years by Ecosystem Sciences and their partners. This work allows us to better understand site‑specific conditions and develop effective, targeted restoration strategies for addressing habitat concerns throughout the system.
