EXECUTIVE SUMMARY / PROJECT ABSTRACT
The Little Troublesome Stream and Wetland Restoration Site, completed in December 2009, restored a total of 2,188 linear feet of stream in the Upper Cape Fear River Basin. In addition, there are approximately 4.5 acres of wetland preservation, 1.9 acres of wetland enhancement, and 2,754 linear feet of stream preservation within the site. The project is located in the USGS Hydrologic Unit 03030002-010030 of the Cape Fear River Basin. This HU is within the EEP’s Upper Cape Fear Basin Local Watershed Plan and is also listed as a Targeted Local Watershed (TLW) in EEP’s Cape Fear River Basin Priorities Plan (2009). The project goals and objectives are listed below. Project Goals • Restore a stable channel morphology to the project stream that is capable of moving the flows and sediment provided by its watershed. • Improve water quality for an NCDWQ stream, classified as a Class C and Nutrient Sensitive Waters by reducing bank erosion and bed degradation. • Enhance aquatic and terrestrial habitat. • Enhance and preserve existing wetlands and forested buffers. Project Objectives • Restore 2,188 linear feet of stable stream channel with the appropriate pattern, profile, and dimension that can support a gravel transport system • Restore a natural riparian buffer. • Restore the hyporheic zone in the project streams and re-establish the natural stream features. • Plug ditches to increase groundwater input to existing wetlands. • Plant native trees and shrubs throughout the site. The vegetation monitoring success criterion for the planted stream riparian zone is a density of 320 stems/acre after the third year of monitoring and an allowance for 10% mortality in the fourth and fifth years with a final density of 260 stems/acre. The third-year vegetation monitoring was based on the Level 2 CVS-EEP vegetation monitoring protocol. The site’s average density for this monitoring period is 637 planted stems/acre, including live stakes, and 607 planted stems/acre, excluding live stakes. All of the eight plots had greater than 320 planted stems/acre. There are many volunteer woody stems throughout the site. Including volunteers, the monitoring plots averaged 3,232 total stems/acre. The 2012 monitoring found that the slope from the left bank of the tributary to the terrace (the northfacing slope) had sparse vegetation coverage with some bare areas. There has been high live stake survival along the tributary and variable survival along Little Troublesome Creek. Multiflora rose (Rosa multiflora) is scattered throughout the easement along Little Troublesome Creek and UT1. A small area of Japanese hops (Humulus japonicas) is located on Little Troublesome at Station 21+30. Third-year monitoring found Little Troublesome Creek to be stable, with only minor changes from the previous monitoring conditions. The tributary has had isolated areas of localized bed degradation and bank erosion since construction. For the third monitoring year these areas (predominantly from Station 52+80 to 53+40) appear to be stabilizing. The isolated areas of erosion on the outer bends of Little Troublesome are trending toward stability, with only two areas still displaying minor bank erosion. There are three beaver dams on Little Troublesome Creek. The first one is located near the start of Little Troublesome at Station 12+25 on the riffle grade control structure. The second beaver dam is located at approximately Stations 21+25 in conjunction with a fallen tree, and the third dam is located at 22+90. The longitudinal and cross-sectional data also reflect overall stability in the project streams. As a part of the Little Troublesome Site EEP Project # 749

stream success criterion, the stream must experience at least two bankfull events, each in separate monitoring years. The site has experienced multiple bankfull events since construction. 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 Baseline Monitoring Report (formerly Mitigation Plan) and in the Mitigation Plan (formerly the Restoration Plan) documents available on the EEPs website. All raw data supporting the tables and figures in the appendices are available from EEP upon request. 2.0
METHODOLOGY
The survey data were collected with a total station instrument the week of August 20, 2012. The stationing for the longitudinal profile is based on the thalweg stationing and has been adjusted to match grade control structures from previous longitudinal profiles. Some of the cross-section surveys on Little Troublesome Creek showed slightly lower top of bank measurements than the baseline measurements. In the cases where the top of bank measurement was only nominally lower than the bankfull elevation, the bankfull width was limited to just include the distance between the tops of left and right banks. This ensures that the bankfull width measurement is representative of the cross-section, and not abnormally large because of insignificant changes in the surveyed cross-section. The CVS-EEP protocol, Level 2 (http://cvs.bio.unc.edu/methods.htm) was used to collect vegetation data from the site. The vegetation monitoring was completed during the week of September 4, 2012. 3.0

Each project is listed with its PLANTED stems per acre, for each year. This excludes Proj, planted live stakes. Each project is listed with its TOTAL stems per acre, for each year. This includes Proj, total stems live stakes, all planted stems, and all natural/volunteer stems. List of plots surveyed with location and summary data (live stems, dead stems, Plots missing, etc.). Vigor Frequency distribution of vigor classes for stems for all plots. Vigor by Spp Frequency distribution of vigor classes listed by species. List of most frequent damage classes with number of occurrences and percent of Damage total stems impacted by each. Damage by Spp Damage values tallied by type for each species. Damage by Plot Damage values tallied by type for each plot. A matrix of the count of PLANTED living stems of each species for each plot; dead Planted Stems by Plot and Spp and missing stems are excluded. A matrix of the count of total living stems of each species (planted and natural ALL Stems by Plot and spp volunteers combined) for each plot; dead and missing stems are excluded.
