 Stream Bank Restoration

Roslyn Park Sandy Run Stream Bank Restoration and Management Project



NAM Planning and Design LLC  assessed the environmental health of the portion of the Sandy Run that flows through Roslyn Park as part of a grant received by Abington Trails. The report indicated that the primary concern is the limited riparian buffer due to the parks intense use as a recreation area combined with the colonization of non-native invasive plant species. NAM proposed a two-phased project to remove the invasive plants and replace them with native trees, shrubs and grasses. Planting native species along the stream bed helps prevent stream erosion, reduces flooding, provides habitat for a variety of animals, limits the encroachment of invasive non-native plant species and buffers non-point-source pollution.

Phase I of the project was completed in September of 2006. The project, supported by a Tree Vitalize grant, was a collaborative effort of the Abington Township Parks and Recreation Department, the EAC, the STC,  and Abington Trails. A 15,000 square-foot area along the northern side of Sandy Run was cleared and replanted with native species trees and plants. More than 50 volunteers from the community participated. Fifteen hundred trees, shrubs, flowers, and grasses were planted in a six-hour period. The photos below show the area prior to restoration, on the day of planting (September 2006), and 11 months later (August 2007).

 


 
 
 
 
 
 
 
 

 

Phase II of the project was completed in October 2007.  Approximately 50,000 square feet of streambank was restored on the southern side of the creek, opposite the Phase I area. Initially, the Parks and Recreation staff removed invasive trees and plants. Over 50 volunteers completed the effort by planting 2500 native trees, shrubs, flowers, and grasses. For more information, view the Information Sign (pdf document) that has been posted near the work site.  Before and after pictures are shown below.

 
Phase III of the project was completed in October 2008. Approximately 10,000 square feet of streambank was restored on the southern side of the creek, south of the Phase II area. Initially, the Parks and Recreation staff removed invasive trees and plants. Over 50 volunteers completed the effort by planting 500 native trees, shrubs flowers, and grasses.
 
Phase IV of the project was completed in April 2010 to complete the restoration on the southern side of the creek,  south from the Phase III area to Susquehanna Rd. As preparation, the Parks and Recreation staff removed invasive trees and plants, mostly Japanese Knotweed. Over 50 volunteers completed the effort by planting over 500 native trees, shrubs, flowers, and grasses.

Today, the streambank is full of beautiful flowers, flowering shrubs, and native trees. The plant roots are stabilizing the soil and preventing erosion of the nearby playing fields.
