MONITORING REPORT
EXECUTIVE SUMMARY The Holly Grove Site is located in Guilford County, North Carolina within the Cape Fear River Basin, Cataloging Unit 03030002. The project consisted of restoring, enhancing, and preserving approximately 21,000 linear feet of stream, restoring approximately 42 acres of riparian buffers, and preserving approximately 1.11 acres of wetlands. The Site is in a rural setting in the Southern Outer Piedmont hydrophysiographic ecoregion and was previously used to grow row crops with woody vegetation confined to isolated areas. Prior to restoration, the channels were highly degraded due to unrestricted livestock access, channelization activities, and lack of riparian vegetation. The restoration design was based on a Priority Level 1 and 2 approach to restore proper channel dimension and allow for appropriate sediment transport. Restoration practices on this project were implemented with the intent of minimizing unnecessary disturbance to adjacent land and to protect mature riparian vegetation where it existed. The constructed stream profile has restored stable bed morphology including appropriate riffle-pool sequencing. Cross-vanes, J-Hook vanes, and in-stream log structures have been integrated into the channel to provide grade control, maintain stable streambanks while the riparian vegetation establishes, and provide in-stream habitat. Biodegradable fiber matting was used to provide temporary stabilization on the newly graded streambanks. Excavated materials from the existing channel were used to backfill around in-stream structures and to build riffles with a natural substrate and function. Hydrology Following completion of the construction in October of 2008, the Site has been subjected to one greater-than-bankfull event and at least two near bankfull events. It should be noted that, prior to completion of construction, Tropical Storm Fay (August 2008) produced a high-flow event in which floodwaters crested 2.5 feet above bankfull. Approximately seventy percent (70%) of the project was complete at that time and subjected to this high water event. Stream The restored stream reaches have successfully managed the high-flow events of the first year. Visual inspection of the Site following the greater-than-bankfull event in August of 2008 and the bankfull event in June 2009 revealed no noticeable adjustments in the bed or banks. The overall grade of the channel has been maintained and the banks of the channels are intact throughout the Site. Vegetation Native woody and herbaceous species were used to establish, at minimum, a fifty-foot riparian buffer on each side of the restored reach. Herbaceous species have successfully established throughout the entire site. The riparian buffer bare-root planting had an overall survival rate of 65% and showed significant evidence of additional volunteer species becoming established. In general, herbaceous planting resulted in vigorous growth throughout the site. Planned Action Continued visual monitoring is planned for the few stream areas that have been identified as “Areas of Concern”. Repair work is not warranted at this time on any of the areas. This is based on the judgment that these issues have not risen to level of posing a threat to channel or structure Holly Grove / Restoration Systems

MONITORING REPORT
PROJECT GOALS, BACKGROUND, AND ATTRIBUTES
The purpose of the Holly Grove Stream Restoration Site (Site) was to restore degraded sections of Buckhorn Creek and several of its tributaries located in Guilford County, North Carolina. This monitoring report presents information regarding the site and watershed conditions, the restoration approach for the project, the monitoring results, remedial action plan and detailed monitoring drawings of the site. 1.1
General Project Description
Buckhorn Creek is located approximately 15 miles northeast of the City of Greensboro in rural Guilford County, North Carolina (Figure 1: Vicinity Map). The site consists of approximately 42 acres of floodplain, approximately 21,000 linear feet of stream designated as Buckhorn Creek and its tributaries, and 1.11 acres of existing wetlands (Figure 2: Project Map). The stream reaches consist of perennial, first and second order streams that have historically been impacted by riparian and bank vegetation removal, channel straightening, unrestricted livestock access, and agricultural land-use practices. Existing land use within the site consists of forested areas and row crops. The site is located within moderately sloping colluvial valleys and elevations range from approximately 615 to 720 feet above sea level. Past land management activities have consisted of timber harvesting with subsequent land clearing for agricultural uses including cattle and row crop farming. The land outside of the conservation easement remains in active agricultural production. 1.1.1 USGS and NCDWQ River Basin Designations The project reach is located in the Haw River watershed of the Cape Fear River Basin (United States Geological Survey (USGS) 14-digit Hydrologic Unit 03030002020070) within North Carolina Division of Water Quality (NCDWQ) sub-basin 03-06-02. This sub-basin is primarily rural agriculture, although residential land use accounts for a significant portion. Buckhorn Creek drains into Reedy Fork Creek approximately ¾ miles downstream of the Site, which in turn flows to the Haw River eight miles downstream. 1.1.2
NCDWQ Surface Water Classification
Reedy Fork Creek in the vicinity of the Site is assigned a best usage classification of C, NSW by the NCDWQ and as such there are no restrictions on watershed development or types of discharge. These waters are suitable for aquatic life propagation and survival, fishing, wildlife, secondary recreation, and agriculture. Secondary recreation includes wading, boating, and other uses not involving human body contact with water on an organized or frequent basis. The supplemental classification, NSW (Nutrient Sensitive Waters) includes areas with water quality problems associated with excessive plant growth resulting from nutrient enrichment. The portion of Reedy Fork Creek to which Buckhorn Creek drains and the portion of the Haw River that is approximately two miles east of the Site are listed on the DWQ final

2004 and draft 2006 303(d) lists. Streams which are included in the 303(d) list do not meet water quality standards or have impaired uses. 1.2
Project Goals and Objectives
The primary goals of the Holly Grove Stream Restoration Project are to: • Restore aquatic and riparian habitat within the on-site portions of the Buckhorn Creek watershed. • Restore geomorphic stability to the subject stream reaches. These goals will be accomplished through the following objectives: • Restoration of approximately forty-two acres of Mesic Mixed Hardwood Forest along both sides of Buckhorn Creek and its tributaries. • Removing nonpoint sources of pollution associated with agricultural activities including the establishment of a native woody riparian buffer (at least 50’ wide) adjacent to streams and wetlands to treat surface runoff which may be laden with sediment and/or agricultural pollutants from the adjacent landscape. • Reestablishing stream stability and the capacity to transport watershed flows and sediment loads by restoring a stable dimension, pattern, and profile supported by natural in-stream habitat and grade/bank stabilization structures. • Promoting floodwater attenuation through a) conveying bankfull stream flows through construction of bankfull bench, b) restoring secondary, entrenched tributaries thereby reducing floodwater velocities, and c) revegetating floodplains to increase frictional resistance on floodwaters crossing the Site. • Improving aquatic habitat by enhancing stream bed variability and the use of instream structures. • Providing wildlife habitat including fringe and forest edge. These accomplishments will result in: • Restoration and enhancement of 15,822 Stream Mitigation Units. • Protecting the Site with a perpetual conservation easement. 1.3
Project Structure
The project is composed of seven distinct reaches; the main channel, Buckhorn Creek, and each of its tributaries, Middle Branch, West Branch, East Branch, Lower East Branch, Southeast Creek, and Southwest Creek. The project structure is tabulated in the corresponding Table 1 (See Below). 1.4
Restoration Type and Approach
Restoration and enhancement practices implemented on this project were designed to minimize unnecessary disturbance to adjacent land and to protect mature riparian vegetation where it exists. Consideration was given to the potential functional lift provided by restoration activities in comparison to the functional lift that could be realized through the natural process of channel evolution. Included in this consideration was an attempt to determine the disturbance and sedimentation that could occur as a result of this natural process. Where restoration was determined to be warranted,

MONITORING REPORT
consideration was given to which reaches could best be served by maintaining as much of the existing channel pattern as possible. The proposed channels of Buckhorn Creek and its tributaries are designed as Type B4c streams with the exception of the lower reach of Middle Branch. This channel configuration provides the most stable and natural form in the moderately sloping colluvial valleys that are found throughout the Site. Not only does it effectively convey bankfull discharge and sediment load but also conforms to the natural conveyance of flood flows. Additionally, since broad alluvial valleys are generally not found within the Site, the lower sinuosity of the Type B4c streams will result in minimizing grading and earthwork activities. The proposed channel dimensions, patterns, and profiles are based on hydraulic relationships and morphologic dimensionless ratios of the reference reaches. Restoration activities included restoring stable channel morphology supported by natural in-stream habitat and grade/bank stabilization structures, the elimination of accelerated bank erosion, and reestablishment of native riparian buffers at least 50 feet in width. Exotic riparian vegetation was removed in areas of the project to allow for replanting of native riparian species. In-stream structures were installed to provide for enhanced aquatic habitat, protection of the newly constructed stream banks, and grade control for the newly constructed channel. 1.5

PROJECT CONDITION AND MONITORING RESULTS
2.1
Vegetation Assessment
The Carolina Vegetation Survey – Ecosystem Enhancement Program (CVS-EEP) 2008 protocol for recording vegetation (Lee et. al 2008) was used to determine the planting pattern of woody stems with respect to species, spacing, and density as well as to forecast survivability and growth of planted stems in subsequent monitoring years. Eleven (11) randomly placed 10 meter by 10 meter vegetative sampling plots were established within the project easement area. The corners of each monitoring plot have been marked in the field and their position documented by GPS survey. Plots were placed within the applicable planting zones to capture the heterogeneity of the designed vegetative communities. Plot corners were permanently marked with rebar and recorded during the baseline survey. All planted stems and plot corners were marked with orange flagging tape to facilitate relocation during subsequent monitoring years. A reference photograph was taken for each plot at the origin looking diagonally across the plot to the opposite corner. Year 1 vegetation for the Site occurred on October 27-28, 2009. The project has an average of 361 planted stems per acre, which is above the interim success criterion of 320 steams per acre at the end of the Year 3 monitoring period. The riparian buffer planting had an overall survival rate of 65% but showed significant evidence of additional volunteer species taking root. 2.1.1
Stem Counts
Across all vegetation monitoring plots (VP), Year 1 monitoring documented a moderate survivability range of 162 to 567 planted stems per acre. VP2 had the lowest average stem density whereas VPC had the highest. VP2, 5, & 8 did not meet the interim success criterion. Approximately 17% of total planted stems were missing and 18% were dead. Of these, silky willow and common witchhazel had the highest mortality rates. Twentyone (21) species were documented among the vegetation plots, a 12.5% reduction in the total species planted. Several species such as black walnut, willow oak, winged elm, possum haw, and willow were represented by only one individual. Approximately 37% of planted stems had a vigor code of good or excellent. High numbers of natural stems were found in seven of the eleven vegetation monitoring plots. Volunteer stems were also found in vegetation plots VP6, 7, A, & B but in significantly lower numbers. It is expected that recruitment will continue to contribute to the total stem density for the restoration site. 2.1.2
Vegetative Problem
No significant vegetation problem areas were noted within the vegetation monitoring plots on-site although some damage and mortality was recorded. Of all damaged, missing, or dead stems within the vegetation monitoring plots 52% of the damage has been attributed to browsing activity by deer and 47% to insects. Expansion of invasive

exotic plant populations should be monitored both within the vegetation plots in which they occur and within the larger restoration area. It should be noted that after the vegetation survey was conducted VP7 was partially mowed along with the gas easement that crosses Southeast Creek. 2.1.3 Vegetation Plot Photos A photo point was established in each vegetation plot. Photo points are positioned for each plot at the origin facing diagonally across the plot to the opposite corner. The photographs were captured on the same day as the vegetation plot surveys (Appendix A). 2.2
Stream Assessment
Monitoring protocol follows that outlined within the EEP Site Specific Mitigation Plan and detailed in the U.S. Army Corps of Engineers (USACE) Stream Mitigation Guidelines for Monitoring Level I. Specifically, stream monitoring included measurements of stream dimension, profile, pattern, bed materials, photo documentation, and stream bankfull return interval. The restored stream reaches have managed the extreme flow events of the first year. Streambanks remain intact and stable and fully vegetated throughout the site. Vegetation has grown into many riffles on the main channel due to a lack of shade and mature buffer. This has limited the mobility of bed material but has not had noticeable effects on overall stability. All in-stream structures remain intact and fully functional with the exception of a few minor piping issues. 2.2.1 Hydrology Since completion of construction in October of 2008, the site has been subjected to at least one greater-than-bankfull event and several bankfull or near-bankfull events. In August of 2008, Tropical Storm Fay crossed central North Carolina resulting in eight (8) inches of rainfall on-site and water elevations 2.5 feet above bankfull on Buckhorn Creek. Approximately seventy percent (70%) of the project was complete at that time and subjected to this estimated fifty-year storm event. In October of 2008, locally heavy rainfall produced a bankfull event at the Site during the final stages of construction. In June of 2009, heavy rainfall resulted in water elevations 0.2 to 0.3 feet above bankfull. Heavy rainfall associated with remnants of Hurricane Ida produced one additional event in November of 2009, after monitoring was completed which again resulted in water elevations above bankfull.

MONITORING REPORT
2.2.2 Geomorphology Following the procedures established in the USDA Forest Service Manual (Harrelson et al 1994) and the methodologies utilized in the Rosgen stream assessment and classification system (Rosgen 1994, 1996), data collected consisted of detailed dimension and pattern measurements, longitudinal profiles, and bed materials sampling. Re-survey of the permanent cross sections and profile reaches have shown only minimal alterations in local bed elevations with the bed form and the channel pattern remaining consistent with the As-built condition. All eight riffle cross sections exhibit consistent maximum depth while six of the eight retain nearly the same cross-sectional area as documented in the baseline monitoring. Six of the eight pool cross-sections have maintained their depth and cross-sectional area and two show only slight adjustments relative to the As-built condition. Location of bed features relative to the pattern is consistent with the As-built survey. Pebble counts were conducted at each riffle cross-section, as well as across the overall study reaches. Pebble count data was plotted by size distribution in order to assess the D50 and D84 size class. On Buckhorn Creek the material size generally increased from the As-built condition with the D50 on Reach 1 and 2 increasing from 38mm to 67mm and from 38mm to 61mm. Likewise the D84 increased on both of these reaches. On Reach 1 of Buckhorn the D50 remained constant while the D84 decreased from 118mm to 64mm. This may be due in part to the fact that Reach 1 is at the upstream end of the project and may be receiving finer sediment input from upstream of the Site where the channel remains degraded. It also may be related to the significant growth of vegetation in the riffles that may be trapping finer particles in the bed. All of the tributaries, with the exception of Southeast Creek, showed an increase in the D50 over the As-built condition, although generally the increases were not appreciable. The D50 on Middle Branch increased from 10mm to 21mm and from 12mm to 15mm. On Lower East Branch the D50 increased from 7mm to 10mm and Southwest Creek increased from 0.3mm to 7mm. The D50 on Southeast Creek remained constant at 0.1mm which was to be expected since the primary bed material is clay and there is a farm pond located immediately upstream which traps much of the sediment from the watershed. Table VI. BEHI and Sediment Export Estimates – (Not Required in Year 1) 2.2.3 Problem Areas In the year following construction of the Holly Grove Stream Restoration Site, a few minor problem areas have been documented. 1.) Several riffles on Buckhorn Creek exhibit excessive vegetation in the channel bed. 2.) There were six (6) locations of piping identified at log vanes. 3.) There was one (1) area of bank scour identified. Inadequate shade due to lack of mature riparian buffer has allowed vegetation to take root in the bed matrix. It is anticipated that this vegetation will die back during the winter but

will reestablish during each growing season until sufficient shading is provided by the canopy of the buffer. This has affected bedload transport by limiting bed mobility, but it is not expected to have any significant impact on the overall stability or integrity of the channel bed. Continued visual monitoring is planned for the stream areas that have been identified as “Areas of Concern”. Repair work is not warranted at this time on any of the areas. This is based on the judgment that these issues have not risen to level of posing a threat to channel or structure stability and are not resulting in excessive erosion. It is recommended that natural stream processes and natural re-vegetation be allowed the opportunity to mend these areas and then reassess their condition in the next monitoring cycle. 2.2.4 Photo Reference Stations Photograph reference Stations (PRSs) have been established to assist in characterizing the site and to allow qualitative evaluation of the site conditions. The location of each photo station has been permanently marked in the field and the bearing/orientation of the photograph is indicated on the As-built plans to allow for consistent repetition. A total of twenty-eight (28) PRSs have been established along the restored stream (Appendix B). Sixteen (16) of these PRSs have been located upstream of the permanent monitoring cross sections. These photographs are taken facing downstream looking at the section, and show as much of the banks and channel as possible. 2.2.5

MONITORING REPORT
EXECUTIVE SUMMARY The Holly Grove Site is located in Guilford County, North Carolina within the Cape Fear River Basin, Cataloging Unit 03030002. The project consisted of restoring, enhancing, and preserving approximately 21,000 linear feet of stream, restoring approximately 42 acres of riparian buffers, and preserving approximately 1.11 acres of wetlands. The Site is in a rural setting in the Southern Outer Piedmont hydrophysiographic ecoregion and was previously used to grow row crops with woody vegetation confined to isolated areas. Prior to restoration, the channels were highly degraded due to unrestricted livestock access, channelization activities, and lack of riparian vegetation. The restoration design was based on a Priority Level 1 and 2 approach to restore proper channel dimension and allow for appropriate sediment transport. Restoration practices on this project were implemented with the intent of minimizing unnecessary disturbance to adjacent land and to protect mature riparian vegetation where it existed. The constructed stream profile has restored stable bed morphology including appropriate riffle-pool sequencing. Cross-vanes, J-Hook vanes, and in-stream log structures have been integrated into the channel to provide grade control, maintain stable streambanks while the riparian vegetation establishes, and provide in-stream habitat. Biodegradable fiber matting was used to provide temporary stabilization on the newly graded streambanks. Excavated materials from the existing channel were used to backfill around in-stream structures and to build riffles with a natural substrate and function. Hydrology Following completion of the construction in October of 2008, the Site has been subjected to one greater-than-bankfull event and at least two near bankfull events. It should be noted that, prior to completion of construction, Tropical Storm Fay (August 2008) produced a high-flow event in which floodwaters crested 2.5 feet above bankfull. Approximately seventy percent (70%) of the project was complete at that time and subjected to this high water event. Stream The restored stream reaches have successfully managed the high-flow events of the first year. Visual inspection of the Site following the greater-than-bankfull event in August of 2008 and the bankfull event in June 2009 revealed no noticeable adjustments in the bed or banks. The overall grade of the channel has been maintained and the banks of the channels are intact throughout the Site. Vegetation Native woody and herbaceous species were used to establish, at minimum, a fifty-foot riparian buffer on each side of the restored reach. Herbaceous species have successfully established throughout the entire site. The riparian buffer bare-root planting had an overall survival rate of 65% and showed significant evidence of additional volunteer species becoming established. In general, herbaceous planting resulted in vigorous growth throughout the site. Planned Action Continued visual monitoring is planned for the few stream areas that have been identified as “Areas of Concern”. Repair work is not warranted at this time on any of the areas. This is based on the judgment that these issues have not risen to level of posing a threat to channel or structure Holly Grove / Restoration Systems

MONITORING REPORT
PROJECT GOALS, BACKGROUND, AND ATTRIBUTES
The purpose of the Holly Grove Stream Restoration Site (Site) was to restore degraded sections of Buckhorn Creek and several of its tributaries located in Guilford County, North Carolina. This monitoring report presents information regarding the site and watershed conditions, the restoration approach for the project, the monitoring results, remedial action plan and detailed monitoring drawings of the site. 1.1
General Project Description
Buckhorn Creek is located approximately 15 miles northeast of the City of Greensboro in rural Guilford County, North Carolina (Figure 1: Vicinity Map). The site consists of approximately 42 acres of floodplain, approximately 21,000 linear feet of stream designated as Buckhorn Creek and its tributaries, and 1.11 acres of existing wetlands (Figure 2: Project Map). The stream reaches consist of perennial, first and second order streams that have historically been impacted by riparian and bank vegetation removal, channel straightening, unrestricted livestock access, and agricultural land-use practices. Existing land use within the site consists of forested areas and row crops. The site is located within moderately sloping colluvial valleys and elevations range from approximately 615 to 720 feet above sea level. Past land management activities have consisted of timber harvesting with subsequent land clearing for agricultural uses including cattle and row crop farming. The land outside of the conservation easement remains in active agricultural production. 1.1.1 USGS and NCDWQ River Basin Designations The project reach is located in the Haw River watershed of the Cape Fear River Basin (United States Geological Survey (USGS) 14-digit Hydrologic Unit 03030002020070) within North Carolina Division of Water Quality (NCDWQ) sub-basin 03-06-02. This sub-basin is primarily rural agriculture, although residential land use accounts for a significant portion. Buckhorn Creek drains into Reedy Fork Creek approximately ¾ miles downstream of the Site, which in turn flows to the Haw River eight miles downstream. 1.1.2
NCDWQ Surface Water Classification
Reedy Fork Creek in the vicinity of the Site is assigned a best usage classification of C, NSW by the NCDWQ and as such there are no restrictions on watershed development or types of discharge. These waters are suitable for aquatic life propagation and survival, fishing, wildlife, secondary recreation, and agriculture. Secondary recreation includes wading, boating, and other uses not involving human body contact with water on an organized or frequent basis. The supplemental classification, NSW (Nutrient Sensitive Waters) includes areas with water quality problems associated with excessive plant growth resulting from nutrient enrichment. The portion of Reedy Fork Creek to which Buckhorn Creek drains and the portion of the Haw River that is approximately two miles east of the Site are listed on the DWQ final

2004 and draft 2006 303(d) lists. Streams which are included in the 303(d) list do not meet water quality standards or have impaired uses. 1.2
Project Goals and Objectives
The primary goals of the Holly Grove Stream Restoration Project are to: • Restore aquatic and riparian habitat within the on-site portions of the Buckhorn Creek watershed. • Restore geomorphic stability to the subject stream reaches. These goals will be accomplished through the following objectives: • Restoration of approximately forty-two acres of Mesic Mixed Hardwood Forest along both sides of Buckhorn Creek and its tributaries. • Removing nonpoint sources of pollution associated with agricultural activities including the establishment of a native woody riparian buffer (at least 50’ wide) adjacent to streams and wetlands to treat surface runoff which may be laden with sediment and/or agricultural pollutants from the adjacent landscape. • Reestablishing stream stability and the capacity to transport watershed flows and sediment loads by restoring a stable dimension, pattern, and profile supported by natural in-stream habitat and grade/bank stabilization structures. • Promoting floodwater attenuation through a) conveying bankfull stream flows through construction of bankfull bench, b) restoring secondary, entrenched tributaries thereby reducing floodwater velocities, and c) revegetating floodplains to increase frictional resistance on floodwaters crossing the Site. • Improving aquatic habitat by enhancing stream bed variability and the use of instream structures. • Providing wildlife habitat including fringe and forest edge. These accomplishments will result in: • Restoration and enhancement of 15,822 Stream Mitigation Units. • Protecting the Site with a perpetual conservation easement. 1.3
Project Structure
The project is composed of seven distinct reaches; the main channel, Buckhorn Creek, and each of its tributaries, Middle Branch, West Branch, East Branch, Lower East Branch, Southeast Creek, and Southwest Creek. The project structure is tabulated in the corresponding Table 1 (See Below). 1.4
Restoration Type and Approach
Restoration and enhancement practices implemented on this project were designed to minimize unnecessary disturbance to adjacent land and to protect mature riparian vegetation where it exists. Consideration was given to the potential functional lift provided by restoration activities in comparison to the functional lift that could be realized through the natural process of channel evolution. Included in this consideration was an attempt to determine the disturbance and sedimentation that could occur as a result of this natural process. Where restoration was determined to be warranted,

MONITORING REPORT
consideration was given to which reaches could best be served by maintaining as much of the existing channel pattern as possible. The proposed channels of Buckhorn Creek and its tributaries are designed as Type B4c streams with the exception of the lower reach of Middle Branch. This channel configuration provides the most stable and natural form in the moderately sloping colluvial valleys that are found throughout the Site. Not only does it effectively convey bankfull discharge and sediment load but also conforms to the natural conveyance of flood flows. Additionally, since broad alluvial valleys are generally not found within the Site, the lower sinuosity of the Type B4c streams will result in minimizing grading and earthwork activities. The proposed channel dimensions, patterns, and profiles are based on hydraulic relationships and morphologic dimensionless ratios of the reference reaches. Restoration activities included restoring stable channel morphology supported by natural in-stream habitat and grade/bank stabilization structures, the elimination of accelerated bank erosion, and reestablishment of native riparian buffers at least 50 feet in width. Exotic riparian vegetation was removed in areas of the project to allow for replanting of native riparian species. In-stream structures were installed to provide for enhanced aquatic habitat, protection of the newly constructed stream banks, and grade control for the newly constructed channel. 1.5

PROJECT CONDITION AND MONITORING RESULTS
2.1
Vegetation Assessment
The Carolina Vegetation Survey – Ecosystem Enhancement Program (CVS-EEP) 2008 protocol for recording vegetation (Lee et. al 2008) was used to determine the planting pattern of woody stems with respect to species, spacing, and density as well as to forecast survivability and growth of planted stems in subsequent monitoring years. Eleven (11) randomly placed 10 meter by 10 meter vegetative sampling plots were established within the project easement area. The corners of each monitoring plot have been marked in the field and their position documented by GPS survey. Plots were placed within the applicable planting zones to capture the heterogeneity of the designed vegetative communities. Plot corners were permanently marked with rebar and recorded during the baseline survey. All planted stems and plot corners were marked with orange flagging tape to facilitate relocation during subsequent monitoring years. A reference photograph was taken for each plot at the origin looking diagonally across the plot to the opposite corner. Year 1 vegetation for the Site occurred on October 27-28, 2009. The project has an average of 361 planted stems per acre, which is above the interim success criterion of 320 steams per acre at the end of the Year 3 monitoring period. The riparian buffer planting had an overall survival rate of 65% but showed significant evidence of additional volunteer species taking root. 2.1.1
Stem Counts
Across all vegetation monitoring plots (VP), Year 1 monitoring documented a moderate survivability range of 162 to 567 planted stems per acre. VP2 had the lowest average stem density whereas VPC had the highest. VP2, 5, & 8 did not meet the interim success criterion. Approximately 17% of total planted stems were missing and 18% were dead. Of these, silky willow and common witchhazel had the highest mortality rates. Twentyone (21) species were documented among the vegetation plots, a 12.5% reduction in the total species planted. Several species such as black walnut, willow oak, winged elm, possum haw, and willow were represented by only one individual. Approximately 37% of planted stems had a vigor code of good or excellent. High numbers of natural stems were found in seven of the eleven vegetation monitoring plots. Volunteer stems were also found in vegetation plots VP6, 7, A, & B but in significantly lower numbers. It is expected that recruitment will continue to contribute to the total stem density for the restoration site. 2.1.2
Vegetative Problem
No significant vegetation problem areas were noted within the vegetation monitoring plots on-site although some damage and mortality was recorded. Of all damaged, missing, or dead stems within the vegetation monitoring plots 52% of the damage has been attributed to browsing activity by deer and 47% to insects. Expansion of invasive

exotic plant populations should be monitored both within the vegetation plots in which they occur and within the larger restoration area. It should be noted that after the vegetation survey was conducted VP7 was partially mowed along with the gas easement that crosses Southeast Creek. 2.1.3 Vegetation Plot Photos A photo point was established in each vegetation plot. Photo points are positioned for each plot at the origin facing diagonally across the plot to the opposite corner. The photographs were captured on the same day as the vegetation plot surveys (Appendix A). 2.2
Stream Assessment
Monitoring protocol follows that outlined within the EEP Site Specific Mitigation Plan and detailed in the U.S. Army Corps of Engineers (USACE) Stream Mitigation Guidelines for Monitoring Level I. Specifically, stream monitoring included measurements of stream dimension, profile, pattern, bed materials, photo documentation, and stream bankfull return interval. The restored stream reaches have managed the extreme flow events of the first year. Streambanks remain intact and stable and fully vegetated throughout the site. Vegetation has grown into many riffles on the main channel due to a lack of shade and mature buffer. This has limited the mobility of bed material but has not had noticeable effects on overall stability. All in-stream structures remain intact and fully functional with the exception of a few minor piping issues. 2.2.1 Hydrology Since completion of construction in October of 2008, the site has been subjected to at least one greater-than-bankfull event and several bankfull or near-bankfull events. In August of 2008, Tropical Storm Fay crossed central North Carolina resulting in eight (8) inches of rainfall on-site and water elevations 2.5 feet above bankfull on Buckhorn Creek. Approximately seventy percent (70%) of the project was complete at that time and subjected to this estimated fifty-year storm event. In October of 2008, locally heavy rainfall produced a bankfull event at the Site during the final stages of construction. In June of 2009, heavy rainfall resulted in water elevations 0.2 to 0.3 feet above bankfull. Heavy rainfall associated with remnants of Hurricane Ida produced one additional event in November of 2009, after monitoring was completed which again resulted in water elevations above bankfull.

2.2.2 Geomorphology Following the procedures established in the USDA Forest Service Manual (Harrelson et al 1994) and the methodologies utilized in the Rosgen stream assessment and classification system (Rosgen 1994, 1996), data collected consisted of detailed dimension and pattern measurements, longitudinal profiles, and bed materials sampling. Re-survey of the permanent cross sections and profile reaches have shown only minimal alterations in local bed elevations with the bed form and the channel pattern remaining consistent with the As-built condition. All eight riffle cross sections exhibit consistent maximum depth while six of the eight retain nearly the same cross-sectional area as documented in the baseline monitoring. Six of the eight pool cross-sections have maintained their depth and cross-sectional area and two show only slight adjustments relative to the As-built condition. Location of bed features relative to the pattern is consistent with the As-built survey. Pebble counts were conducted at each riffle cross-section, as well as across the overall study reaches. Pebble count data was plotted by size distribution in order to assess the D50 and D84 size class. On Buckhorn Creek the material size generally increased from the As-built condition with the D50 on Reach 1 and 2 increasing from 38mm to 67mm and from 38mm to 61mm. Likewise the D84 increased on both of these reaches. On Reach 1 of Buckhorn the D50 remained constant while the D84 decreased from 118mm to 64mm. This may be due in part to the fact that Reach 1 is at the upstream end of the project and may be receiving finer sediment input from upstream of the Site where the channel remains degraded. It also may be related to the significant growth of vegetation in the riffles that may be trapping finer particles in the bed. All of the tributaries, with the exception of Southeast Creek, showed an increase in the D50 over the As-built condition, although generally the increases were not appreciable. The D50 on Middle Branch increased from 10mm to 21mm and from 12mm to 15mm. On Lower East Branch the D50 increased from 7mm to 10mm and Southwest Creek increased from 0.3mm to 7mm. The D50 on Southeast Creek remained constant at 0.1mm which was to be expected since the primary bed material is clay and there is a farm pond located immediately upstream which traps much of the sediment from the watershed. Table VI. BEHI and Sediment Export Estimates – (Not Required in Year 1) 2.2.3 Problem Areas In the year following construction of the Holly Grove Stream Restoration Site, a few minor problem areas have been documented. 1.) Several riffles on Buckhorn Creek exhibit excessive vegetation in the channel bed. 2.) There were six (6) locations of piping identified at log vanes. 3.) There was one (1) area of bank scour identified. Inadequate shade due to lack of mature riparian buffer has allowed vegetation to take root in the bed matrix. It is anticipated that this vegetation will die back during the winter but

will reestablish during each growing season until sufficient shading is provided by the canopy of the buffer. This has affected bedload transport by limiting bed mobility, but it is not expected to have any significant impact on the overall stability or integrity of the channel bed. Continued visual monitoring is planned for the stream areas that have been identified as “Areas of Concern”. Repair work is not warranted at this time on any of the areas. This is based on the judgment that these issues have not risen to level of posing a threat to channel or structure stability and are not resulting in excessive erosion. It is recommended that natural stream processes and natural re-vegetation be allowed the opportunity to mend these areas and then reassess their condition in the next monitoring cycle. 2.2.4 Photo Reference Stations Photograph reference Stations (PRSs) have been established to assist in characterizing the site and to allow qualitative evaluation of the site conditions. The location of each photo station has been permanently marked in the field and the bearing/orientation of the photograph is indicated on the As-built plans to allow for consistent repetition. A total of twenty-eight (28) PRSs have been established along the restored stream (Appendix B). Sixteen (16) of these PRSs have been located upstream of the permanent monitoring cross sections. These photographs are taken facing downstream looking at the section, and show as much of the banks and channel as possible. 2.2.5
