EXECUTIVE SUMMARY / PROJECT ABSTRACT
In 2004, the North Carolina Ecosystem Enhancement Program (EEP) conducted stream restoration at Brown Bark Park within the Buffalo Creek Watershed in Greensboro, North Carolina. The 0.3-mi2 watershed is located within the USGS 14-digit HUC 03030002020040 and the NCDWQ Sub-basin 03-06-02 of the Cape Fear River Basin. The project restored approximately 2,834 linear feet of channel. Project construction occurred in 2004. The project goals and objectives are listed below. • • • • •
Restore unstable stream channel to natural stable form by modifying dimension, pattern, and/or profile based on reference reach parameters. Improve floodplain functionality by matching bankfull stage with floodplain elevation. Establish native floodplain vegetation through a forested riparian buffer. Improve the natural aesthetics of the stream corridor. Obtain mitigation credits for unavoidable impacts to streams within the same Hydrologic Unit Code.
The riparian buffer was planted with seven different species of bare root trees and four different species of live stakes. Three vegetation monitoring plots were established during the as-built survey: two buffer plots, each approximately 25’ x 100’, and one live stake plot, approximately 175’ x 5’. The fifth year of monitoring found an average of 279 stems per acre in the buffer plots, and 2,639 stems per acre in the live stake plot. Due to the urban nature of the project, there are several exotic species that are present at the project site. These species include mimosa (Albizia julibrissin), white mulberry (Morus alba), Japanese honeysuckle (Lonicera japonica), ornamental pear (Pyrus calleryana), multiflora rose (Rosa multiflora), and porcelainberry (Ampelopsis brevipedunculata). The invasive species listed do not exist in dense, dominant patches, they are scattered and are generally low in number. EEP has indicated that the City of Greensboro is taking over invasive control moving forward into stewardship. The fifth year monitoring found the vegetation component of the project to be on track to meeting the success criteria. Although the vegetation plots met the success criteria, the longer, narrow nature of the buffer in combination with plot placement made for 10-15 foot wide strips at various places within the buffer that exhibited lower woody stem densities and were subject to supplemental planting in late winter 2009/2010. These areas were mainly between the benching and upland zones. The total acreage subject to supplemental planting was approximately 0.9 acres. The plants were larger caliper material, 3 years in age, 5-10 gallon containerized with substantial root mass. EEP plans to observe these stems and summarize survival for 1 or 2 more growing seasons before offering the project for final closeout. The stream assessment completed during the fifth year of monitoring found the stream to be functioning for the majority of the project. Longitudinal profile and channel dimensions have changed minimally from the as-built conditions. The majority of the in-stream structures are functioning and some previously documented areas of erosion have stabilized with vegetation. Summary information/data related to the occurrence of items such as beaver or encroachment and statistics related to performance of various project and monitoring elements can be found in the tables and figures in the report appendices. Narrative background and supporting information formerly found in these reports can be found in the mitigation and restoration plan documents available on the EEPs website. All raw data supporting the tables and figures in the appendices are available upon request.
