Progress 10/01/09 to 09/30/14
Outputs
OUTPUTS: Activities: The following stream restoration projects were implemented to establish long-term evaluation and demonstration sites: (1) Purlear Creek, Wilkes County, Rendezvous Mountain Educational State Forest, NC Forest Service Forest Resources; (2) Shawneehaw Creek, Avery County; (3) Bolin Creek, Orange County, Town of Chapel Hill. Ten previously implemented stream restoration projects were monitored for performance. Events: The 2010 and 2012 Southeast Stream Restoration Conferences served as forum for 400+ scientists and practitioners to share knowledge on project design, implementation, and evaluation to improve the practice of stream restoration. Workshops and field days were conducted to teach over 600 stream restoration practitioners about effective stream assessment, design, and implementation techniques. Services: Technical advice was provided to 30 stream restoration practitioners regarding design review, project planning, and implementation. Products: Six graduate students received PhD and MS degrees in Biological and Agricultural Engineering with a focus on stream restoration. PARTICIPANTS: Jason Zink, Extension Associate, Biological and Agricultural Engineering George Price, Extension Associate, Biological and Agricultural Engineering Michael Shaffer, Extension Associate, Biological and Agricultural Engineering Barbara Doll, Extension Associate, Biological and Agricultural Engineering TARGET AUDIENCES: Consulting environmental professionals, natural resource managers, government regulatory agencies PROJECT MODIFICATIONS: Nothing significant to report during this reporting period.
Impacts
Changes in knowledge and actions resulted from hands-on technical workshops conducted for approximately 600 stream restoration professionals. These changes were documented using follow-up questionnaires to determine how engineering principles are being applied in ongoing restoration projects. Changes in ecosystem conditions were documented through monitoring of geomorphic and ecological parameters.

Impacts
Changes in knowledge occurred following presentations, workshop, and field demonstrations for restoration practitioners learning about innovations in restoration technology. Changes in actions occurred as practitioners and funding agencies applied best practices for planning, designing, constructing, and monitoring stream restoration projects. Changes in conditions occurred as innovative restoration projects were implemented to improve water quality ecological conditions in stream systems.

Progress 10/01/07 to 09/30/08
Outputs
OUTPUTS: Stream restoration projects are being monitored for their physical and biological condition and compared with pre-construction conditions as well as reference conditions. Projects are selected to represent various watershed conditions based on size, land use, and ecological functions. Physical monitoring includes stream channel dimension, pattern, and bed profile, in addition to stream bed material size. Restoration success criteria are being developed based on the relative stability of the channel physical features over time. Changes in stream morphology are being related to hydrology, land use, and restoration design and construction approaches. Biological monitoring includes macroinvertebrate and vegetation sampling to evaluate ecological functions of restored stream corridors. Data from high quality reference stream sites are used to determine desirable index values for a matrix of stream systems. These data provide valuable information about the macroinvertebrate functional feeding group assemblages across stream orders. PARTICIPANTS: David Penrose, Extension Associate, Biological and Agricultural Engineering Jason Zink, Extension Associate, Biological and Agricultural Engineering George Price, Extension Associate, Biological and Agricultural Engineering Justin Church, Extension Associate, Biological and Agricultural Engineering Michael Shaffer, Extension Associate, Biological and Agricultural Engineering Jan Patterson, Extension Associate, Biological and Agricultural Engineering Barbara Doll, Extension Associate, Biological and Agricultural Engineering TARGET AUDIENCES: Consulting environmental professionals, natural resource managers, government regulatory agencies PROJECT MODIFICATIONS: Not relevant to this project.
Impacts
Results are being used to plan, design, and construct effective stream restoration projects to meet mitigation goals. The functional index is applied to restored reaches to evaluate success of the project by comparison with desirable values determined from the NC Division of Water Quality stream assessments and from stable upstream channels. Further, an increasing ordination of the index will be proposed for success of restored sites, based on the distance from the desired index value, and acknowledging that restoration is time dependent. The incremental change of the index toward the undisturbed system value will indicate the level of success in restoring the benthic habitat and stable geometry.
