PROJECT SETTING AND BACKGROUND SUMMARY
The Cane Creek Tributary Site (CCTS) is a full-delivery project that was developed for the North Carolina Ecosystem Enhancement Program (EEP). The project restored, enhanced, and preserved 19,059 linear feet on an Unnamed Tributary to Cane Creek and other associated tributaries, and included planting a functional Piedmont Alluvial Forest floodplain community along with Mesic Mixed Hardwood Forest to develop an effective riparian buffer. Prior to restoration, the project streams had been impacted by livestock and land clearing. These impacts resulted in bank erosion on all of the tributaries and severe incision on selected tributaries. There were also spoil piles remaining from land clearing, which disrupted overland flow paths. The streams had experienced bank erosion, which led to excessive sediment throughout the site. Overall the CCTS contained a series of tributaries in varying degrees of instability. Since construction, supplemental planting has occurred on portions of the site to address poor vigor and survivability in the buffer. Supplemental planting was conducted at the site during the 2010/2011, and 2012 dormant season. Stream maintenance was conducted at the site in 2009 and 2012. The maintenance involved, isolated terrace slope stabilization, bank stabilization, and other small areas of maintenance. These areas were generally isolated and caused by local issues associated with overland flow or concentrated runoff from outside of the easement. They were not indicative of any widespread instability at the site. Overall the site is stable and well vegetated.

PROJECT GOALS AND OBJECTIVES The goals and objectives of the restoration project are as follows: Project Goals: Restore the stream’s riparian buffer. Create a stable network of headwater streams. Project Objectives: Plant a functional Piedmont Alluvial Forest floodplain community along with a Mesic Mixed Hardwood Forest to create an effective riparian buffer. Arrest bed elevation lowering and stabilize seep outlets. Stop bank erosion by developing the appropriate channel dimension and stabilizing with vegetation. Remove relic spoil piles that disrupt overland flow paths. Exclude livestock from the riparian areas with fencing.

EEP RECOMMENDATIONS AND CONCLUSIONS
The stream assessment found the stream to be stable overall. There are isolated areas of erosion on the stream banks and the side slopes, but there are no systematic problems that indicate that the project streams are becoming unstable. It is also important to note that all of the streams across the site have grade control from in-stream structures, and in some instances significant bedrock. With multiple bankfull events since construction, the stream has met the success criterion of at least two bankfull events occurring in separate years over the course of the monitoring period. There are some plots with low planted stem densities, including five plots with planted stem densities below 260 stems/acre: plots 5, 8, 13, 17, and 18. When including volunteers in these five plots, all plots are above the 260 total stems/acre density. The monitored vegetation plots within the stream buffer revealed that the planted vegetation is growing well with an average of 356 stems/acre. The overall vegetation assessment found the site has met the vegetative success criteria for monitoring year 5. Overall the stream and the site's vegetation condition indicate that it is on a path to success. The EEP recommends that this site be closed out.

PROJECT SETTING AND BACKGROUND SUMMARY
The Cane Creek Tributary Site (CCTS) is a full-delivery project that was developed for the North Carolina Ecosystem Enhancement Program (EEP). The project restored, enhanced, and preserved 19,059 linear feet on an Unnamed Tributary to Cane Creek and other associated tributaries, and included planting a functional Piedmont Alluvial Forest floodplain community along with Mesic Mixed Hardwood Forest to develop an effective riparian buffer. Prior to restoration, the project streams had been impacted by livestock and land clearing. These impacts resulted in bank erosion on all of the tributaries and severe incision on selected tributaries. There were also spoil piles remaining from land clearing, which disrupted overland flow paths. The streams had experienced bank erosion, which led to excessive sediment throughout the site. Overall the CCTS contained a series of tributaries in varying degrees of instability. Since construction, supplemental planting has occurred on portions of the site to address poor vigor and survivability in the buffer. Supplemental planting was conducted at the site during the 2010/2011, and 2012 dormant season. Stream maintenance was conducted at the site in 2009 and 2012. The maintenance involved, isolated terrace slope stabilization, bank stabilization, and other small areas of maintenance. These areas were generally isolated and caused by local issues associated with overland flow or concentrated runoff from outside of the easement. They were not indicative of any widespread instability at the site. Overall the site is stable and well vegetated.

PROJECT GOALS AND OBJECTIVES The goals and objectives of the restoration project are as follows: Project Goals: Restore the stream’s riparian buffer. Create a stable network of headwater streams. Project Objectives: Plant a functional Piedmont Alluvial Forest floodplain community along with a Mesic Mixed Hardwood Forest to create an effective riparian buffer. Arrest bed elevation lowering and stabilize seep outlets. Stop bank erosion by developing the appropriate channel dimension and stabilizing with vegetation. Remove relic spoil piles that disrupt overland flow paths. Exclude livestock from the riparian areas with fencing.

EEP RECOMMENDATIONS AND CONCLUSIONS
The stream assessment found the stream to be stable overall. There are isolated areas of erosion on the stream banks and the side slopes, but there are no systematic problems that indicate that the project streams are becoming unstable. It is also important to note that all of the streams across the site have grade control from in-stream structures, and in some instances significant bedrock. With multiple bankfull events since construction, the stream has met the success criterion of at least two bankfull events occurring in separate years over the course of the monitoring period. There are some plots with low planted stem densities, including five plots with planted stem densities below 260 stems/acre: plots 5, 8, 13, 17, and 18. When including volunteers in these five plots, all plots are above the 260 total stems/acre density. The monitored vegetation plots within the stream buffer revealed that the planted vegetation is growing well with an average of 356 stems/acre. The overall vegetation assessment found the site has met the vegetative success criteria for monitoring year 5. Overall the stream and the site's vegetation condition indicate that it is on a path to success. The EEP recommends that this site be closed out.
