P and U Lands Restoration Site Phase 4 iii PCS Phosphate Company, Inc.
Fourth Annual Report April 2019

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 was not completed until later in 2014 and was not planted until spring of 2015; the
final 132 acres planted in 2015 for the P and U Lands mitigation site are tracked as Phase 4.
This report includes results of fourth annual hydrology and vegetation monitoring for the 132
acres of P and U Lands Phase 4 conducted by CZR Incorporated (CZR) of Wilmington, NC. The
first two annual reports for Phase 4 referenced a total of 134 acres; final acreage calculations for
the entire P and U Lands project phases were corrected in 2017.
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 allow 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
P and U Lands Restoration Site Phase 4 1 PCS Phosphate Company, Inc.
Fourth Annual Report April 2019

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
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 water 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 132 -acre Phase 4 planted portion of the site is expected to successfully
re-establish approximately:
❖ 17 wetland acres of headwater forest and
❖ 115 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 In -Situ) 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 the likelihood of disturbance or equipment loss by
black bears.
To serve as additional hydrology controls for the entire
TROLLs were installed in the Rodman Tract in 2013 in an
elevations similar to portions of Phase 4 (7 to 9 feet) and four

previous well locations within the adjacent Bay City Farm in late 2015. According to the soils map
and LiDAR 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, the second annual survey occurred October -
November 2016, the third annual survey occurred in October 2017, and the fourth annual survey
occurred in November 2018. The plots represent approximately 2 percent of the restoration area
(Figure 2). Stem count data are included in Appendix A.
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, the second in October 2016, the
third in November 2017, and the fourth in October 2018.
2.5. Reporting. The three prior annual reports on monitoring results were provided as
required in 2016, 2017, and 2018. (CZR Incorporated 2016, 2017, and 2018).
3.0 2018 RESULTS
3.1 Rainfall. Total rainfall in 2018 at Bay City was 67.6 inches, 17.0 inches more than
2017. The 30 -day rolling total of 2018 Bay City rainfall shows the following periods as above
normal (above the WETS 70th percentile longer than several days): 26 May — 27 June, 28 July —
23 August, 14 September — 14 October, and 2 November — 5 December (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 2018, all 41 weeks of the growing season were
considered normal with no drought status in the vicinity of the P and U Lands project area.
3.2 Hydrology. During all rainfall conditions and normal and below normal rainfall
conditions, all of the eight wells recorded a wetland hydroperiod (Table 2, Table 3, Figure 6, and
Figure 7). Of the eight wells in Phase 4, during all rainfall conditions, one well had a hydroperiod
for the entire growing season, six wells for >25-75 percent of the growing season, and one well
for >12.5-25 percent of the growing season (Table 3, Figure 7). After exclusion of periods of
above WETS normal rainfall, seven wells had a hydroperiod for >25-75 percent of the growing
season and one well for >12.5-25 percent of the growing season (Table 2, Figure 6).
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 the majority (six of
eight) of the wells in Phase 4. The four Bay City control wells also had wetland hydroperiods, one
well for >6-12.5 percent, two wells for >25-75 percent, and one well for >75 percent of the
growing season. Only one hydroperiod for the control wells were affected by the above normal
rainfall; BCRW44 changed from >75 percent to >25-75 percent of the growing season.
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
P and U Lands Restoration Site Phase 4 3 PCS Phosphate Company, Inc.
Fourth Annual Report April 2019

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. After the fourth year (2018),
percent survival of alive stems for Zone 2 (1 plot) and Zone 3 (7 plots) was 82 percent each, with
a combined total of 16 identified species (11 trees and 5 shrubs). Appendix A contains the
number of stems that were alive in each plot for the fall 2018 survey.
Overall survival of trees that were unquestionably alive in the eight plots from baseline to
the fourth annual fall survey was 85 percent, with a corresponding density of 317 trees per acre,
three trees per acre less than last year (Table 4). Of the 12 species of large and small tree
species tagged at baseline, 11 species had surviving stems. Individual percent survival ranged
from 67 to 100 percent, with nine 75 percent or greater. The trees that could only be identified to
genus (Nyssa or Quercus) had 0 percent 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 87 percent and a density of 323 trees per acre, 20 stems fewer per acre
than last year. The current density is higher than the density required at the end of five years
(260 stems).
Overall survival of shrubs that were unquestionably alive from the baseline to the fourth
annual fall survey was 89 percent with a corresponding density of 14 shrubs per acre, the same
as last year (Table 4). Virginia sweetspire (Itea virginica), fetterbush (Lyonia lucida), had 100
percent survival. A shrub identified as swamp dogwood (Cornus foemina) since baseline, was
changed to possumhaw (Viburnum nudum). This correction resulted in 125 percent survival for
possumhaw and 83 percent survival for swamp dogwood in Table 4.
When the trees and shrubs that were definitely alive are combined, density increases to
331 stems per acre and if stems with uncertain survival are added, the density increases to 337
stems per acre. This phase has a diverse assemblage of species with nine tree species and four
shrub species with a 75 percent or greater survival; five tree species and three shrub species
have with a 90 percent or greater survival.
4.0 SUMMARY
Total rainfall in 2018 at Bay City was 67.6 inches, 17.0 inches more than 2017. The 30 -
day rolling total of 2018 Bay City rainfall shows the following periods as above normal (above the
WETS 70th percentile longer than several days 26 May — 27 June, 28 July — 23 August, 14
September — 14 October, and 2 November — 5 December. 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, six wells for
>25-75 percent of the growing season, and one well for >12.5-25 percent of the growing season.
After exclusion of the four periods of above WETS normal rainfall, seven wells had a hydroperiod
for >25-75 percent of the growing season and one well for >12.5-25 percent of the growing
season.
Overall survival of trees that were unquestionably alive in the eight plots from baseline to
the fourth annual fall survey in 2018 was 85 percent with a corresponding density of 317 trees per
acre. Overall survival of shrubs that were unquestionably alive from baseline to the fourth annual
fall survey was 89 percent with a corresponding density of 14 shrubs per acre. When the trees
and shrubs that were definitely alive are combined, density increases to 331 stems per acre and if
stems with uncertain survival are added, the density increases to 337 stems per acre. The three
most abundant tree species comprise 70 percent of the tree species and the two most abundant
shrub species compose 79 percent of the shrub species.
