P and U Lands Restoration Site Phase 4 iii PCS Phosphate Company, Inc. Second Annual Report April 2017 1.0 PROJECT OVERVIEW 1.1 History. The approximately 3,667 -acre P and U Lands restoration site is part of the PCS Phosphate Company Inc.'s (PCS) compensatory mitigation to offset unavoidable impacts to wetlands and waters authorized under United States Army Corps of Engineers (USACE) Action ID: 200110096 and North Carolina Division of Water Quality (DWQ) Water Quality Certification (WQC) #2008-0868 version 2.0. The P and U designation have no special meaning other than that was the historic label given to PCS and Weyerhaeuser properties with similar ownership agreements. The P and U Lands site is a key component linking PCS Phosphate Company, Inc.'s (PCS) Parker Farm Mitigation Site, Bay City Farm Mitigation Site, Gum Run Mitigation Site, and the South Creek Corridor into a large and varied collection of restored wetland and preserved natural areas (South Creek Corridor Complex). Unlike most other PCS mitigation sites, the P and U Lands are not prior -converted agricultural fields. Other than the existing roads, most of the acreage in which earthwork occurred was in some stage of silviculture, usually various -aged pine stands, and contained regularly spaced ditches (deeper than the agricultural ditches on other restoration sites that were filled in as part of restoration work) and the bedding common to pine plantations. The removal of all standing timber and stumps and post-harvest debris presented particular challenges as the organic soils precluded safe burning of the timber slash on site. Consequently, some of the debris was piled into somewhat evenly shaped and sized mounds throughout the site which provide additional wildlife habitat. As described in the mitigation plan prepared for the pre -construction notification (PCN) to the USACE (CZR 2012), the site was planned to be constructed in three phases as shown on Figure 1. These three phases were completed during the following three years: Phase 1 construction was completed in 2011 and planted in February 2012, Phase 2 construction began in 2012 and was planted in 2013; however, construction at the lower elevations took additional time due to excessive wetness. This delay prevented the restoration of approximately 268 acres of the original Phase 2 which included Gum Swamp Run. During the third year, these 268 acres and Gum Swamp Run were restored and included with the Phase 3 work completed in 2013 (planted in February of 2014). Because Phase 3 was the largest of the three phases, some of the Phase 3 work, approximately 138 acres, was not completed until later in 2014 and was not planted until spring of 2015. This report includes results of second annual hydrology and vegetation monitoring for the 138 acres of P and U Lands Phase 4 conducted by CZR Incorporated (CZR) of Wilmington, NC. The design team consisted of Jonathan T. Ricketts, Inc. of Palm Beach Gardens, FL, the restoration design engineer, PCS, and CZR. Earthwork was performed by Sawyer's Land Developing, Inc. out of Belhaven, NC and supervised by the design team. Phase 1 and 2 restoration activities occurred September 2011 -March 2013. Phase 3 construction began in Gum Swamp Run on 9 May 2012 and on 22 June 2012 on the larger Phase 3 area. Phase 3 was constructed with a total of 14 NC Division of Land Resources Erosion and Sediment Control (DLR) permits for land clearing which were subsequently modified to all for the construction of the interior ditch plugs and perimeter berms and ditches. Phase 4 activities were included in three of the Phase 3 DLR permits (#s 22, 23, and 24). Planting of Phase 4 occurred in mid-February 2015. 1.2 Location. The P and U Lands site is located east and west of Bay City Road (SR1002), approximately 4.5 miles southeast of Aurora, Richland Township, North Carolina. Bay City Road runs through the P Lands portion of the site, which is bounded on the east by SR 1918 (Peele Road is the unpaved extension of SR 1918) and on the south by "County Line Road" (a gated gravel road along the Beaufort/Pamlico County border). The U Lands portion of the site lies west and southwest of Bay City Farm (the western portion of the P Lands site referred to as the "panhandle" separates Bay City Farm from the U Lands). South Creek and the South Creek P and U Lands Restoration Site Phase 4 1 PCS Phosphate Company, Inc. Second Annual Report April 2017 Canal form the northern and northwestern boundaries, Bonner/Rodman Road forms the western boundary, and the Pamlico/Beaufort County line forms the southern boundary of the U Lands (County Line Road itself is the southern boundary of only the eastern half of the U Lands as the western limit of County Line Road terminates at the midpoint of the south property line). The entire site is accessed via multiple gated roads along Bay City Road, Peele Road, County Line Road, Gum Road, and/or Jaime/Executive Road. The site is located within the Pamlico Hydrologic Unit 03020104 of the Tar -Pamlico River basin within the South Creek subbasin at latitude 35.233831 and longitude 76.775742. Portions of the site can be found on the USGS Aurora, Bayboro, South Creek, and Vandemere quadrangles (Figure 1). 1.3 Goals and Performance Criteria. The primary goal of the entire project is to re- establish a self-sustaining functional wetland complex to allow surface flow to move through vegetated wetlands before reaching any stream. Mitigation yields are estimated and performance criteria are described for the project in detail in the Compensatory Mitigation Plan for P and U Lands Restoration Site (CZR 2012). Performance criteria for Phase 4 are summarized in Table 1. Over time the 138 -acre Phase 4 portion of the site is expected to successfully re-establish approximately: ❖ 17.8 wetland acres of headwater forest and ❖ 116.5 wetland acres of non-riverine swamp forest. 2.0 REQUIREMENTS 2.1 Normal Rainfall and Growing Season. A continuous electronic rain gauge on the adjacent Bay City Mitigation Site is downloaded once a month and its data are used in conjunction with data from nearby automated weather stations (e.g., NRCS WETS data from NOAA's site at Aurora and rain gauges at other nearby monitoring sites) to determine normal rainfall during the monitoring period. Bay City data were compared to the WETS range of normal precipitation to determine if Bay City rainfall was within the normal range. The range of normal precipitation for this report refers to the 30th and 70th percentile thresholds of the probability of having onsite rainfall amounts less than or higher than those thresholds. The range of normal and the 30 -day rolling total data lines begin on the last day of each month and the WETS -Aurora monthly precipitation total is plotted on the last day of each month. Under the 2010 regional guidance from the Corps of Engineers for wetland hydroperiods, the normal growing season for Beaufort County is 28 February to 6 December or 282 days during non -leap years (WETS table for Beaufort County first/last freeze date 28 degrees F 50 percent probability) (US Army Corps of Engineers 2010). At the suggestion of the Corps' Washington regulatory field office, data collected between 1 February and 27 February provide important information related to analyses of site hydrology during the early growing season, but are not part of the hydroperiod calculation for success. 2.2 Hydrology. Figure 2 depicts the locations of hydrology monitoring equipment, Figure 3 shows these locations on Beaufort County soil polygons, and Figure 4 shows all monitoring locations on the as -built LiDAR. To document surface storage and hydroperiods of all wetland types on the site, eight semi -continuous electronic Level Troll water level monitoring wells (manufactured by InSitu) are deployed at a density of approximately 1 well/15 acres across all planted areas of Phase 4. Exclosures constructed of barbed wire wrapped around metal fence posts were built around each well to reduce likelihood of disturbance or equipment loss by black bears. To serve as additional hydrology controls for the entire P and U Lands site, three Level Trolls were installed in the Rodman Tract in 2013 in an area mapped as Ponzer soil at elevations similar to portions of Phase 4 (7 to 9 feet) and four Level Trolls were installed at previous well locations within the adjacent Bay City Farm in late 2015. According to the soils map and LiDAR P and U Lands Restoration Site Phase 4 2 PCS Phosphate Company, Inc. Second Annual Report April 2017 data, these four locations also are underlain by Ponzer soils but two are at slightly higher elevations than the three Rodman wells (9 to 11 feet) and two are slightly lower (4 to 6 feet). Level Trolls collect data every 1.5 hours, are downloaded once a month, and the data evaluated to document wetland hydroperiods. Wetland hydroperiods are calculated by counting consecutive days with water level no deeper than 12 inches below the soil surface during the growing season under normal or below normal rainfall conditions and then for all rainfall conditions. 2.3 Vegetation. The first annual survey of the eight 0.3 -acre planted vegetation monitoring plots occurred August -October 2015 and the second annual survey occurred October - November 2016. The plots represent approximately 2 percent of the restoration area (Figure 2). 2.4 Photographic Documentation. Due to the small size and similarity to the surrounding areas of Phase 3, no photo stations were established specifically for Phase 4. The view for Phase 3 photo station PLPS 21 faces into Phase 4, so this station is included in Appendix B. The first annual photo was taken December 2015 and the second in October 2016. 2.5. Reporting. The First Annual Report (CZR 2016) on monitoring results was provided as required in 2016. 3.0 2016 RESULTS 3.1 Rainfall. Total rainfall in 2016 at Bay City was 60.6 inches, 4.2 inches more than 2015. The 30 -day rolling total of 2016 Bay City rainfall shows the following periods as above normal (above the WETS 70th percentile longer than several days): 4 February — 4 March, 7 — 28 June, 2 July — 5 August, 12 September — 2 October, and 7 October — 5 November (Figure 5). Wetland hydroperiods were calculated for the entire year regardless of rainfall and also calculated with above normal rainfall periods excluded. The US Drought Monitor (http://droughtmonitor.unl.edu) provides a synthesis of multiple indices and reflects the consensus of federal and academic scientists on regional conditions on a weekly basis (updated each Thursday). In 2016, three of the 41 weeks of the growing season were considered abnormally dry (DO) (19 April — 3 May); the remaining weeks were normal with no drought status in the vicinity of the P and U Lands project area. 3.2 Hydrology. During all rainfall and normal and below normal rainfall conditions, all of the eight wells recorded a wetland hydroperiod (Table 2, Figure 6). Of the eight wells in Phase 4, one well had a hydroperiod for the entire growing season, four wells for >25-75 percent of the growing season, and three wells for >12.5-25 percent of the growing season. After excluding the five periods of above normal rainfall, four wells had a hydroperiod for >25-75 percent of the growing season and four wells for >12.5-25 percent of the growing season. During all rainfall conditions, the three Rodman control wells recorded a wetland hydroperiod for 25-75 percent of the growing season, which is the same as half of the wells in Phase 4. The four Bay City control wells had a wetland hydroperiod, but each well was in one of the four hydrologic zones: >6-12.5 percent, >12.5-25 percent, >25-75 percent, and >75 percent. Hydroperiods for the control wells were not affected by the above normal rainfall. 3.3 Vegetation. Planting zones of Phase 4 were divided into two zones or community types: headwater forest (Z2) and non- riverine swamp forest (Z3). Using only the number of planted stems that were unquestionably alive in the monitoring plots, the most conservative estimate of survival is presented. Some stems may appear dead or questionable, but based on prior monitoring experience, a stem needs to appear dead (or not be found) for two consecutive fall survey events before it can be confidently counted as dead. At the year two 2016 survey, percent survival for Z2 was 85 percent and Z3 was 88 percent with a combined total of 18 P and U Lands Restoration Site Phase 4 3 PCS Phosphate Company, Inc. Second Annual Report April 2017 identified species (12 trees and six shrubs). Appendix A contains the number of stems that were alive in each plot for the fall 2016 survey. Overall survival of trees that were unquestionably alive in the eight plots from the time of planting to the second annual fall survey was 92 percent, with a corresponding density of 338 trees per acre (Table 4). There were five identified tree species that had 90 percent or higher survival: swamp chestnut oak (Quercus michauxii), willow oak (Q. phellos), overcup oak (Q. lyrata), bald cypress (Taxodium distichum), and laurel oak (Q. laurifolia) with 100, 100, 99, 98, and 90 percent respectively. The trees that could only be identified down to the genus Nyssa had the lowest survival with 40 percent; all other tree species had 84 percent or higher survival. If trees with uncertain survival status (stem appeared dead but could not be confirmed) are included with trees that were definitely alive, survival increases to 99 percent and a density of 367 trees per acre. Overall survival of shrubs that were unquestionably alive from the time of planting to the second annual fall survey was 86 percent with a corresponding density of 13 shrubs per acre scattered among the eight species planted (Table 4). Virginia sweetspire (Itea virginica), fetterbush (Lyonia lucida), and possumhaw (Viburnum nudum) all had 100 percent survival and silky dogwood (Cornus amomum) had 0 percent survival. When the trees, shrubs, and unknown species that were definitely alive are combined, density increases to 351 stems per acre and if stems with uncertain survival are added, the density increases to 386 stems per acre. The Corps determined that three tree species have the possibility to outcompete young planted trees at a mitigation site and need to be monitored as nuisance species to ensure they do not take over a mitigation site. These species are loblolly pine (Pinus taeda), red maple (Acer rubrum), and sweetgum (Liquidambar styraciflua). A total of 40 stems were identified in the eight nuisance plots. Only one stem was a nuisance species, a loblolly pine, representing 2.5 percent of all stems present in the nuisance plots. 4.0 SUMMARY Total rainfall in 2016 at Bay City was 60.6 inches, 4.2 inches more than 2015. The 30 - day rolling total of 2016 Bay City rainfall shows the following periods as above normal (above the WETS 70th percentile longer than several days): 4 February — 4 March, 7 — 28 June, 2 July — 5 August, 12 September — 2 October, and 7 October — 5 November. During all rainfall and normal and below normal rainfall conditions, all of the eight wells recorded a wetland hydroperiod. Of the eight wells in Phase 4, one well had a hydroperiod for the entire growing season, four wells for >25-75 percent of the growing season, and three wells for >12.5-25 percent of the growing season. After excluding the five periods of above normal rainfall, four wells had a hydroperiod for >25-75 percent of the growing season and four wells for >12.5-25 percent of the growing season. Overall survival of trees that were unquestionably alive in the eight plots from the time of planting to the second annual fall survey was 92 percent with a corresponding density of 338 trees per acre. Overall survival of shrubs that were unquestionably alive from the time of planting to the first annual fall survey was 86 percent with a corresponding density of 13 shrubs per acre, scattered among the eight species planted. When the trees, shrubs, and unknown species that were definitely alive are combined, density increases to 351 stems per acre and if stems with uncertain survival are added, the density increases to 386 stems per acre.
