EXECUTIVE SUMMARY
Wildlands Engineering, Inc. (Wildlands) implemented a full delivery project at the Sandy Branch
Mitigation Site (Site) for the North Carolina Department of Environmental Quality Division of Mitigation
Services (DMS)to restore a stream and wetland complex within Chatham County, NC.The Sandy Branch
Mitigation site utilizes stream restoration, wetland re-establishment, and wetland rehabilitation
approaches.The project streams total 3,286 linear feet (LF) of perennial streams. Wetland re-
establishment and rehabilitation total 8.540 acres.The Site will generate 3,286.000 stream credits and
7.267 wetland credits. All stream lengths were measured along the stream centerline for stream credit
calculations.
The Site is located approximately seven miles southeast of Siler City, NC (Figure 1) in the Cape Fear River
Basin 8-Digit Hydrologic Unit Code (HUC) 03030003.The Site is located within the DMS Targeted Local
Watershed (TLW)for the Cape Fear River Basin Hydrologic Unit Code (HUC)03030003070050 (Bear
Creek TLW) and the NC DWR Subbasin 03-06-12.The Sandy Branch Mitigation Site is one of the projects
identified in the Upper Rocky River Local Watershed Plan as a priority for stream and wetland
restoration. Sandy Branch and two unnamed tributaries (UT1 and UT2) are located on the Site.The
downstream drainage area of the Site is 463 acres.The Site contains tributaries to Bear Creek,which
flows into the Rocky River and eventually the Deep River.The 18.10-acre Site is protected with a
permanent conservation easement.
The project goals established in the Mitigation Plan (Wildlands, 2019)were completed with
consideration of goals and objectives described in the Cape Fear River Basin Restoration Priorities
(RBRP) plan.The project goals include:
• Improve stream channel stability;
• Improve instream habitat;
• Reconnect channels with floodplains and riparian wetlands;
• Restore wetland hydrology, soils, and plant communities;
• Restore and enhance native floodplain vegetation; and
• Permanently protect the Site from harmful land uses.
The project will contribute to achieving the goals for the watershed listed in the Cape Fear RBRP and
provide ecological benefits within the Cape Fear River Basin. While benefits such as habitat
improvement and geomorphic stability are limited to the Site, others, such as reduced pollutant and
sediment loading, have farther reaching effects.
Site construction was completed in September 2020, and planting was completed in January 2021. As-
built surveys were conducted between September 2020 and January 2021. No major adjustments were
made during construction. Baseline (MVO) profiles and cross-section dimensions closely match the
design parameters. Cross-section widths and pool depths occasionally deviate from the design
parameters but fall within a normal range of variability for natural streams.The Site has been built as
designed and is expected to meet the upcoming monitoring year's performance criteria.

Section 1: PROJECT GOALS, BACKGROUND, AND ATTRIBUTES
1.1 Project Location and Setting
The Sandy Branch Mitigation Site (Site) is located in central Chatham County, approximately seven miles
southeast of Siler City, NC (Figure 1). From Raleigh, NC, take 1-40 W then take US-1 S towards Sanford. In
31.5 miles take exit 70B from US-421 N toward Siler City/Greensboro. Follow US-421 for 14.5 miles and
then turn left onto Elmer Moore Rd.The project will be on your left in 0.1 miles.A conservation
easement was recorded on 18.10 acres of the Site.The Site contains tributaries to Bear Creek, which
flows into the Rocky River, and eventually the Deep River.The Site is located approximately 2.75 miles
upstream of the Bear Creek (Chatham) Aquatic Habitat, a Significant Natural Heritage Area that is
located at the confluence of Bear Creek and Sandy Branch.The Site is located within the DMS Targeted
Local Watershed (TLW) for the Cape Fear River Basin Hydrologic Unit Code (HUC) 03030003070050
(Bear Creek TLW) and the NC DWR Subbasin 03-06-12.The Sandy Branch Mitigation Site is one of the
projects identified in the Upper Rocky River Local Watershed Plan as a priority for stream and wetland
restoration.The 2009 Cape Fear River Basin Restoration Priorities' (RBRP) Cataloging Unit (CU)-wide
functional objectives as well as the TLW goals identified the provision of habitat for the endangered
mussel population (creeper, Atlantic pigtoe, brook floater and notched rainbow) and the Cape Fear
Shiner as a primary goal. Improving water quality is listed as one of the necessities for achieving this
goal.
The Site is located in the Carolina Slate Belt of the Piedmont Physiographic Province.The Piedmont
Province is characterized by gently rolling, well rounded hills with long low ridges and elevations ranging
from 300-1500 feet above sea level.The Site topography and relief are typical for the region.The
Carolina Slate Belt consists of heated and deformed volcanic and sedimentary rocks.The area is called
"Slate Belt" because of the slatey cleavage of many of the surficial rocks.The region's geology also
includes coarse-grained intrusive granites.
Prior to construction activities, cattle were grazed along Sandy Branch Reach 1 and 2, UT1 and UT2.
Cattle access to these streams resulted in significant ecological impacts.Table 4 in Appendix 1 and
Tables 7a-b in Appendix 4 present additional information on pre-restoration conditions.
1.2 Project Goals and Objectives
The project is intended to provide numerous ecological benefits within the Cape Fear River Basin. While
benefits such as habitat improvement and geomorphic stability are limited to the Site, reduced nutrient
and sediment loading have farther reaching effects.Table 1 below describes expected outcomes to
water quality and ecological processes associated with the project goals and objectives.These goals
were established and completed with careful consideration of goals and objectives described in the
RBRP and to meet the DMS mitigation needs while maximizing the ecological and water quality uplift
within the watershed.

1.3 Project Structure, Restoration Type, and Approach
The final Mitigation Plan was approved in December 2019. Construction activities were completed by
Main Stream Earthwork in September 2020.The baseline as-built survey was completed by Summit
Design and Engineering Services in January 2021.The planting was completed by Bruton Natural
Systems, Inc. in January 2021. Refer to Appendix 1 for detailed project activity, history, contact
information, and watershed/Site background information.
1.3.1 Project Structure
The project provides 3,286.000 stream credits and 7.267 wetland credits. Refer to Figure 2 Project
Component/Asset Map for the stream restoration feature exhibits and Table 1 in Appendix 1 for the
project components and mitigation credits for the Site.
1.3.2 Restoration Type and Approach
The design streams were restored to the appropriate type based on the surrounding landscape, climate,
and natural vegetation communities but also with strong consideration to existing watershed
conditions.The project consists of the stream restoration activities as described below (Table 2) and
illustrated in Figure 2.

The design approach for this Site utilized a combination of analog and analytical approaches for stream
restoration. Reference reaches were identified to serve as the basis for design parameters. Channels
were sized based on design discharge hydrologic analysis. Designs were then verified and/or modified
based on a sediment transport analysis.This approach has been used on many successful Piedmont and
Slate Belt restoration projects (Underwood, Foust, Holman Mill, Maney Farm, and Agony Acres
Mitigation Sites) and is appropriate for the goals and objectives for this Site.
The morphologic design parameters are shown in Appendix 4,Tables 7a—7b for the restoration
reaches, and fall within the ranges specified for C4 streams (Rosgen, 1996).The specific values for the
design parameters were selected based on designer experience and judgment and were verified with
morphologic data form reference reach data sets.
1.4 Project History, Contacts, and Attribute Data
The Site was restored by Wildlands Engineering through a full delivery contract with DMS.Tables 2, 3,
and 4 in Appendix 1 provide detailed information regarding the Project Activity and Reporting History,
Project Contacts, and Project Information and Attributes.

Section 2: PERFORMANCE STANDARDS
The stream performance standards for the project will follow approved standards presented in the
Wilmington District Stream and Wetland Compensatory Mitigation Updated in October 2016 by the
North Carolina Interagency Review Team (NCIRT). Annual monitoring and semi-annual site visits will be
conducted by qualified personnel to assess the condition of the project. Specific performance standard
components are proposed for stream morphology, hydrology, and vegetation. Performance standards
will be evaluated throughout the seven-year post-construction monitoring.
2.1 Streams
2.1.1 Dimension
Riffle cross-sections on the restoration reaches should be largely stable and should only show minor
changes in bankfull area, maximum depth ratio, and width-to-depth ratio. Per guidance, bank height
ratios shall not exceed 1.2 and entrenchment ratios shall be at least 2.2 for restored channels to be
considered stable. Riffle cross-sections should largely fall within the parameters defined for channels of
that stream classification. If any changes do occur, these changes will be evaluated to assess whether
the stream channel is showing signs of instability. Indicators of instability include a vertically incising
thalweg or eroding channel banks. Changes in the channel that indicate a movement toward stability or
enhanced habitat include a decrease in the width-to-depth ratio in meandering channels or an increase
in pool depth. Remedial action would not be taken if channel changes indicate a movement toward
stability.
2.1.2 Pattern and Profile
Visual assessments and photo documentation should indicate that streams are remaining stable and do
not indicate a trend toward vertical or lateral instability.
2.1.3 Substrate
Channel substrate materials will be sampled in restoration reaches using the reach-wide pebble count
method. Reaches should show maintenance of coarser substrate in the riffles than in the pools. Riffle
cross-section pebble counts were conducted during as-built baseline monitoring and will not be
conducted during annual monitoring unless observations indicate a trend toward finer substrate and a
comparison is needed.
2.1.4 Photo Documentation
Photographs should illustrate the Site's vegetation and morphological stability on an annual basis. Cross-
section photos should demonstrate no excessive erosion or degradation of the banks. Longitudinal
photos should indicate the absence of persistent bars within the channel or vertical incision. Grade
control structures should remain stable. Deposition of sediment on the bank side of vane arms is
preferable. Maintenance of scour pools on the channel side of vane arms is expected.
2.1.5 Hydrology Documentation
The occurrence of bankfull events will be documented throughout the monitoring period. Four bankfull
flow events must be documented within the seven-year monitoring period and individual events must
occur in separate years. Stream monitoring will continue until performance standards in the form of
four bankfull events in separate years have been documented.
Sandy Branch Mitigation Site
Baseline Monitoring Document and As-Built Baseline Report-FINAL 2-1
2.2 Vegetation
Vegetative performance for riparian buffers associated with the stream restoration component of the
project (buffer widths 0—50ft)will be in accordance with the Stream Mitigation Guidelines issued
October 2016 by the USACE and NCIRT.The success criteria is an interim survival rate of 320 planted
stems per acre at the end of monitoring year three (MY3), 260 stems per acre at the end of MY5, and a
final vegetation survival rate of 210 stems per acre at the end of MY7. Planted vegetation must average
10 feet in height in each plot at the end of the seventh year of monitoring. Vegetation monitoring will be
conducted between July 1"and the end of the of the growing season. Individual plot data will be
provided and will include height, density,vigor, damage (if any), and survival. In fixed vegetation plots,
planted woody stems will be marked annually as needed and given a coordinate, based off a known
origin so they can be found in succeeding monitoring years. Mortality will be determined from the
difference between the previous year's living planted stems and the current year's living planted stems.
The extent of invasive species coverage will be monitored and controlled as necessary throughout the
required seven-year monitoring period.
2.3 Wetlands
The final performance standard for wetland hydrology is based on the soil type on the Site and
associated USACE guidance shall be free groundwater surface within 12 inches of the ground surface for
10%of the growing season under normal precipitation conditions.
2.4 Visual Assessment
Visual assessments should support the specific performance standards for each metric as described
above.
2.5 Schedule and Reporting
Monitoring reports will be prepared in the fall of each year of monitoring and submitted to DMS. Based
on the DMS Annual Monitoring Report Template (June, 2017), the monitoring reports will include the
following:
• Project background which includes project objectives, project structure, restoration type and
approach, location and setting, history and background;
• Monitoring Current Condition Plan View (CCPV) maps with major project elements noted such
as grade control structures, vegetation plots, permanent cross-sections, groundwater wells, and
crest gauges;
• Photographs showing views of the restored Site taken from fixed point stations;
• Assessment of the stability of the Site based on the cross-sections;
• Vegetative data as described above including the establishment of any undesirable plant
species;
• A description of damage by animals or vandalism; and
• Maintenance issues and recommended remediation measures will be detailed and documented.
Sandy Branch Mitigation Site
Baseline Monitoring Document and As-Built Baseline Report-FINAL 2-2
Section 3: MONITORING PLAN
Monitoring will consist of collecting morphological, hydrologic, and vegetative data to assess the project
performance based on the restoration goals and objectives on an annual basis until performance criteria
have been met.The performance of the project will be assessed using measurements of the stream
channel's dimension, substrate composition, permanent photographs, surface water hydrology, and
vegetation.Any areas identified as high priority problems, such as streambank instability,
aggradation/degradation, or lack of vegetation establishment will be evaluated on a case-by-case basis.
The problem areas will be visually noted, and remedial actions will be discussed with DMS staff to
determine a plan of action. A remedial action plan will be submitted if substantial maintenance is
required.The monitoring period will extend seven years beyond completion of construction or until
performance criteria have been met.
3.1 Stream
Geomorphic assessments will follow guidelines outlined in the Stream Channel Reference Sites: An
Illustrated Guide to Field Techniques (Harrelson et al., 1994), methodologies utilized in the Rosgen
stream assessment and classification document(Rosgen, 1994 and 1996), and in the Stream
Restoration: A Natural Channel Design Handbook(Doll et al, 2003). Refer to Figure 3 in Appendix 2 and
Record Drawings in Appendix 5 for monitoring locations discussed below.
3.1.1 Dimension
A total of eight cross-sections were installed along the stream restoration reaches.Two cross-sections
were installed per 1,000 linear feet of stream restoration work,with riffle and pool sections in
proportion to DMS guidance. Each cross-section was permanently marked with pins to establish its
location. Cross-section surveys include points measured at all breaks in slope; including top of bank,
bankfull, edge of water, and thalweg to monitor any deviations in dimension. If moderate bank erosion
is observed along a stream reach during the monitoring period, a series of bank pins will be installed in
representative areas where erosion is occurring for reaches with a bankfull width of greater than five
feet. If required, bank pins will be installed in at least three locations (one in upper third of the pool, one
at the mid-point of the pool, and one in the lower third of the pool). If bank pins are required,they will
be monitored by measuring exposed rebar and maintaining pins flush to bank to capture bank erosion
progression. Annual cross-section surveys will be conducted in monitoring years MY1, MY2, MY3, MY5,
and MY7. Photographs will be taken annually of the cross-sections looking upstream and downstream.
3.1.2 Pattern and Profile
Longitudinal profile surveys will not be conducted during the seven-year monitoring period unless other
indicators during the annual monitoring show a trend toward vertical and lateral instability. If a
longitudinal profile is deemed necessary, monitoring will follow standards as described in the DMS
Monitoring Requirements and Performance Standards for Stream and/or Wetland Mitigation (DMS,
2011)and the 2003 USACE and NCDWR Stream Mitigation Guidance for the necessary reaches. Stream
pattern and profile will be assessed visually as described below in section 3.1.6.
3.1.3 Substrate
A reach-wide pebble count will be performed in four reaches (Sandy Branch Reach 1 and 2, UT1, and
UT2) during monitoring years 1, 2, 3, 5, and 7 for classification purposes and to show that riffles remain
coarser than pools. Riffle cross-section pebble counts were conducted during as-built baseline
monitoring only unless observations indicate a trend toward finer substrate and a comparison is
needed.
Sandy Branch Mitigation Site
Baseline Monitoring Document and As-Built Baseline Report-FINAL 3-1
3.1.4 Photo Reference Points
A total of 18 permanent photograph reference points were established along the stream reaches after
construction. Permanent markers were established so that the same locations and view directions on
the Site are photographed each year. Longitudinal stream photographs will be taken looking upstream
and downstream once a year to visually document stability. Cross-sectional photos will be taken at each
permanent cross-section looking upstream and downstream. Representative digital photos of each
permanent photo point will be taken on the same day the stream assessments are conducted.
3.1.5 Hydrology Documentation
One automated crest gauge was installed on Site.The crest gauge was installed in a surveyed riffle cross-
section on Sandy Branch Reach 2. Crest gauge data will be downloaded during site visits to determine if
a bankfull event has occurred since the last visit. Additionally, photographs will be collected to
document the occurrence of debris lines and sediment deposition as evidence of bankfull events.
3.1.6 Visual Assessment
Visual assessments will be performed at the Site on a semi-annual basis during the seven-year
monitoring period. Problem areas will be noted such as channel instability(i.e. lateral and/or vertical
instability, in-stream structure failure/instability and/or piping, or headcuts), vegetated health (i.e. low
stem density,vegetation mortality, invasive species or encroachment), beaver activity, or livestock
access. Areas of concern will be mapped and accompanied by a written description in the annual report.
Problem areas will be re-evaluated during each subsequent visual assessment. Should remedial actions
be required, recommendations will be provided in the annual monitoring report.
3.2 Vegetation
Planted woody vegetation will be monitored in accordance with the guidelines and procedures
developed by the Carolina Vegetation Survey-EEP Level 2 Protocol (Lee et al., 2006)to monitor and
assess the planted woody vegetation. A total of thirteen standard 10 meter by 10 meter vegetation plots
were established within the project easement area.Three of the thirteen vegetation plots will be
relocated randomly on an annual basis to monitor vegetation health across the Site.
Vegetation plots were randomly established between the conservation easement boundaries and five
feet from the top of stream banks. Fixed vegetation plot corners have been marked and are recoverable
either through field identification or with the use of a GPS unit. Reference photographs were taken at
the origin looking diagonally across the plot to the opposite corner during the baseline monitoring in
January 2021. Subsequent annual assessments following the baseline survey will capture the same
reference photograph locations. Planted woody stems will be marked annually, as needed, based off a
known origin so they can be found in subsequent monitoring years.
Species composition, density, and survival rates will be evaluated on an annual basis by plot and for the
entire Site. Individual plot data will be provided and will include height, density, vigor, damage (if any),
and survival. Mortality will be determined from the difference between the baseline year's living planted
stems and the current year's living planted stems. Vegetation surveys will be conducted during
monitoring years 1, 2, 3, 5, and 7.
3.3 Wetlands
Twelve groundwater monitoring wells equipped with pressure transducers were installed to assess
hydrology in wetland re-establishment and rehabilitation areas. Pressure transducers will record
groundwater pressure at least twice daily. Monitoring well data will be analyzed in consideration of
recorded precipitation, reference well data, and growing season dates. Data from groundwater wells will
be downloaded at regular intervals and included in annual monitoring reports.
Sandy Branch Mitigation Site
Baseline Monitoring Document and As-Built Baseline Report-FINAL 3-2
The estimated growing season for Chatham County is approximately March 18th through November 17th
based on NRCS WETS Tables. A soil temperature probe was installed on-site to determine growing
season dates for each individual monitoring year. Per USACE guidance, the probe was located at a depth
of 12 inches.The growing season will be defined as that portion of the year where soil temperature
remains above 41 degrees Fahrenheit. Soil temperature must be corroborated with bud break and the
growing season may not begin before March 1st of each year when calculating hydroperiods. If a
wetland zone does not meet the performance standard for a given monitoring year, rainfall patterns will
be analyzed, and the hydrograph will be compared to that of the reference wetlands to assess whether
atypical weather conditions occurred during the monitoring period. Monitoring wells and soil
temperature probe locations are shown on Figure 3 in Appendix 2.

Section 4: LAND MANAGEMENT AND CONTINGENCY PLAN
Wildlands will perform maintenance as needed at the Site. A physical inspection of the Site shall be
conducted a minimum of once per year throughout the post-construction monitoring period until
performance standards are met.These site inspections may identify components and features that
require routine maintenance. Routine maintenance should be expected most often in the first two years
following construction and may include one or more of the following components.
4.1 Stream
Stream problem areas will be mapped and included in the CCPV as part of the annual stream
assessment. Stream problems areas may include bank erosion, structure failure, beaver dams,
aggradation/degradation, etc. Routine channel maintenance and repair activities may include chinking
of in-stream structures to prevent piping, securing loose coir matting, and supplemental installations of
live stakes and other target vegetation along the channel. Areas where storm water runoff flows into the
channel may also require maintenance to prevent bank failures and head-cutting.
4.2 Vegetation
Vegetation shall be maintained to ensure the health and vigor of the targeted community. Vegetative
problem areas will be mapped and included in the CCPV as part of the annual vegetation assessment.
Vegetation problem areas may include planted vegetation not meeting performance criteria, persistent
invasive species, barren areas with little to no herbaceous cover, or grass suffocation/crowding of
planted stems. Routine vegetation maintenance and repair activities may include supplemental planting,
pruning, mulching, and fertilizing. Exotic invasive plant species shall be controlled by mechanical and/or
chemical methods. Any vegetation control requiring herbicide application will be performed in
accordance with NC Department of Agriculture rules and regulations.
4.3 Site Boundary
Site boundary issues will be mapped and included in the CCPV as part of the annual visual assessment.
Site boundaries shall be identified in the field to ensure clear distinction between the Site and adjacent
properties. Boundaries are marked with conservation easement signs attached to metal posts. Boundary
markers disturbed, damaged, or destroyed will be repaired and/or replaced on an as needed basis.
Sandy Branch Mitigation Site
Baseline Monitoring Document and As-Built Baseline Report-FINAL 4-1
Section 5: AS-BUILT CONDITION (BASELINE)
The Site construction and as-built surveys were completed between September 2020-January 2021.The
survey included developing an as-built topographic surface; as well as, surveying the as-built channel
centerlines, top of banks, structures, and cross-sections.
5.1 As-Built/Record Drawings
A sealed half-size set of record drawings are in Appendix 5 which includes the post-construction survey,
alignments, structures, and monitoring features. No significant field adjustments were made during
construction that differ from the design plans. Minimal adjustments were made during construction,
where needed, based on field evaluation and are listed below.
5.1.1 Sandy Branch Reach 1
• Station 100+32 boulder sill not installed due to elevation of existing bedrock.
• Station 100+41—Station 100+60 boulder toe substituted for log vane due to elevation of existing
bedrock.
5.1.2 Sandy Branch Reach 2
• Station 111+36 angled log sill substituted for boulder sill due to material availability.
• Station 119+98 angled log sill substituted for boulder sill due to material availability.
• Station 126+74 angled log sill substituted for boulder sill due to material availability.
• Station 127+53 boulder sill not installed due to removal of drop over pool.
• Station 127+74—Station 128+05 boulder toe added for additional bank stability.
• Station 128+97—Station 129+25 brush toe substituted for boulder toe due to material
availability.
5.1.3 UT1
• Station 200+68 angled log sill substituted for boulder sill due to material availability.
• Station 200+84—Station 200+69 boulder toe added for additional bank stability.
5.1.4 UT2
• Station 302+68 rock floodplain outlet added due to observed overland flow.
5.2 Baseline Data Assessment
Baseline monitoring(MYO)was conducted between September and January 2021.The first annual
monitoring assessment(MY1)will be completed in late 2021.The streams will be monitored for a total
of seven years,with the final monitoring activities concluding in 2027.The close-out for the Site will be
conducted in 2028 given the performance criteria have been met.
5.2.1 Morphological State of the Channel
Refer to Appendix 2 for stream photographs and Appendix 4 for summary data tables and morphological
plots.
Profile
The MYO longitudinal profiles closely match the design profile. On the design profiles, pools and riffles
were depicted as straight lines with consistent slopes.The as-built surveyed profiles are not as
consistent in slope due to the size of the rock used for construction. Pool and riffle depths and slopes
are expected to be maintained near design parameter values.The variations in slope and depth do not
Sandy Branch Mitigation Site
Baseline Monitoring Document and As-Built Baseline Report-FINAL 5-1
constitute a problem or indicate a need for remedial actions and will be assessed visually during the site
walks.
Dimension
The MYO channel dimensions fall within specified design parameter ranges.The channels are expected
to maintain dimensions of C4 Rosgen type channels. Summary data and cross-section plots of each
project reach are included in Appendix 4.
Pattern
The MYO pattern metrics fall within the design parameter ranges for all reaches. No major changes to
design alignments were made during construction. Pattern data will be evaluated in MY5 if channel
dimensions or profile indicate that significant geomorphic changes have occurred.
Sediment Transport
As-built shear stress and velocities are similar to design calculations and should reduce the risk of
further erosion along the reaches.The substrate data for each constructed reach was compared to the
design shear stress parameters from the mitigation plan to assess the potential for bed degradation.The
shear stresses calculated for the constructed channels are within the allowable range, which indicates
the channel is not at risk to trend toward channel degradation.
5.2.2 Hydrology
Bankfull events recorded following completion of construction will be reported in the MY1 report.
5.2.3 Wetlands
Wetland data recorded following completion of construction will be reported in the MY1 report.
Groundwater well photographs are in Appendix 2.
5.2.4 Vegetation
The MYO vegetation survey was completed in January 2021.The MYO planted density is 573 stems per
acre which exceeds the MY3 interim stem density requirement of 320 planted stems per acre.
Vegetation Plot photographs are included in Appendix 2 and summary data for each plot are included in
Tables 6a and 6b in Appendix 3.
