Habitat Restoration


DRN is committed to restoring habitat within the Delaware River Basin and improving management practices to guard against habitat degradation. Our Restoration Program, established in 1992, provides technical assistance to and partners with municipalities, agencies, local conservation groups, and private property owners to develop watershed and restoration plans and to implement in-the-ground projects. These planning efforts and constructed projects increase wildlife habitat value, improve stream function and transport, encourage infiltration of stormwater, restore native plant communities, and are neighborhood assets.

DRN’s Restoration Program implements innovative, cost-efficient, ecologically-sound projects that incorporate a myriad of techniques, including:

  • Natural channel design
  • Stormwater Best Management Practices (BMPs)
  • Soil bioengineering
  • Native plant establishment
  • Invasive species management and control
  • Aquatic habitat enhancement
  • Wetland restoration
  • Stream and watershed assessment

Current Projects

Bristol Marsh Buffer Restoration (Buckss County, PA) 
DRN is providing assistance to the Heritage Conservancy and Bristol Borough on restoring a native vegetated buffer around this Delaware River freshwater tidal marsh.  DRN has mapped existing invasive plant species within the buffer and is helping facilitate community workdays to remove these plants and to replant with native species. 

Cooper River Biofilter (Camden County, NJ) 

DRN, with project partners, constructed the biofilter wetland along the Cooper River in 2003 to reduce non-point source pollutants reaching the river.  In October 2010, DRN with the help of volunteers, Camden County, and Fish and Wildlife Service removed invasive plants from around this constructed wetland and replanted with 77 native trees and shrubs.  An additional 22 trees were planted on the opposite river bank at the Camden County Boathouse.  Recent efforts of this project were funded by the Fish and Wildlife Service, Camden County Municipal Utilities Authority, and Cooper River Watershed Association.  

Delaware Estuary Technical Assistance Program (DE, NJ, PA)
DRN provides technical assistance to landowners, municipalities, and watershed organizations working to implement restoration and conservation projects throughout the Delaware Estuary. Activities may include invasive species mapping and management, watershed restoration planning, stream assessments, land use management recommendations, native plantings, wetland restoration, bank stabilization, and in-stream fish habitat enhancement. Project is funded by the National Fish and Wildlife Foundation with matching sources.

Mill Creek Restoration (Berks County, PA) 
DRN, with project partners and the property owner, is restoring 1,350 linear feet of Mill Creek in Berks County, PA which has been damaged by agricultural use. The constructed project will involve soil bioengineering techniques, natural channel design principles, stream fencing, cattle crossings, and establishment of a diverse, wooded riparian buffer. Project is funded through the Schuylkill River Greenway Association with matching sources.

Morrisville Riverfront Preserve Buffer Restoration (BucksCounty, PA)
DRN is working with Morrisville Borough and the EAC to restore a healthy, native riparian buffer to this public preserve along the Delaware River.  Beginning in fall of 2010 efforts will focus first on controlling over 8 acres of Japanese knotweed which is degrading habitat of the buffer.  This project is funded by a grant from the Bucks County Open Space Program with supporting funds from the National Fish and Wildlife Foundation and PA DEP. 

Tinicum Creek Restoration (Bucks County, PA)
DRN, with project partners and the property owners, developed a holistic restoration design to stabilize and improve trout habitat in a half mile of this Exceptional Value, National Wild and Scenic stream. This work builds upon previous studies of the Upper Tinicum Creek watershed completed by DRN. Project was funded by PA DEP with matching sources.

Saddler’s Woods Stormwater Management (Camden County, NJ)
DRN, with its partners, is designing and constructing an innovative stormwater management system to control stormwater entering Saddlers Woods, a preserved 25-acre woodland in Haddon Township NJ with historical significance. Under existing conditions, elevated levels of stormwater runoff are resulting in the instability of the headwater streams flowing through Saddlers Woods. Project is funded by NJ DEP with matching sources.

Swamp Creek Restoration at the Erwinna Covered Bridge (Bucks County, PA)
DRN, with project partners and the property owners, is restoring 1,000 linear feet of Swamp Creek at the Erwinna Covered Bridge in Bucks County, PA. Using natural channel design principles a design will be implemented to restore the channel’s proper dimension, pattern and profile, as well as to improve its approach to the historic covered bridge. Soil bioengineering techniques will be used to stabilize stream banks and to establish a diverse riparian corridor. Project is funded by PA DEP through the Growing Greener Program with matching sources.

West Branch Crum Creek Coldwater Conservation Plan (Chester County, PA)
DRN, with project partners, assessed the Exceptional Value West Branch of Crum Creek and developed a comprehensive Coldwater Conservation Plan in 2009 to protect and enhance the stream’s nature and its wild brown trout population. The plan identifies site-specific recommendations and watershed-wide programs to be implemented by the township, local organizations, and property owners. DRN is now working with landowners to implement plan recommendations and protect the health of this watershed.  Project is funded by the Coldwater Heritage Partnership, National Fish and Wildlife Foundation, PA DEP and other matching sources.

West Wayne Preserve Stormwater Management and Woodland Restoration (Delaware County, PA) 
DRN, with project partners and Radnor Township, developed a concept master plan to manage stormwater and ecologically enhance this 7-acre woodland. Designed measures will meet the community's need for stormwater management, woodland and wetland restoration, wildlife observation, and passive recreation. Project is funded by the township with matching sources.

Remember the River

Remember the River CampaignThe Delaware is the longest undammed river east of the Mississippi, flowing freely for 330 miles as it travels from New York state, through Pennsylvania, New Jersey, and Delaware to the Atlantic Ocean.

Our Remember the River campaign is a tribute to the Delaware. Learn more about this campaign.

Did you know DRN is available to speak at events?

The Delaware Riverkeeper as well as representatives of the Delaware Riverkeeper Network are available to speak about the Delaware River watershed, the threats it faces and our efforts to protect it. Speaker's fees for Delaware Riverkeeper Network staff generally start at $250, but vary depending upon the length of the presentation, the type of function being held, and the financial capabilities of the host organization. Speaker's fees are designated as donations to the Delaware Riverkeeper Network. Part of the operating budget, they help Delaware Riverkeeper Network to champion the rights of the River and its streams as members of our community.
