PRESERVED/TRANSPLANTED PLANT SPECIES OF CONSERVATION
IMPORTANCE MONITORING
Plant species
of conservation importance, including three individuals of Aquilaria
sinensis and 33 individuals of Gmelina chinensis, were identified
within works areas for Contract 2 during the survey conducted in August
2021. All individuals of Aquilaria sinensis and 31 individuals of Gmelina
chinensis were recommended being preserved in-situ
while two individuals of Gmelina chinensis (RT-07 and RT-08) were
recommended being transplanted to the receptor site in accordance with the
Detailed Preservation and/or Translocation Plan for Plant Species of
Conservation Importance approved under Condition 2.21 of EP-519/2016.
Initial tree
survey was conducted in September 2021 under Contract No. NL/2020/02 before the
commencement of construction works. According to the initial tree survey
conducted, the in-situ preserved plant species of conservation
importance of which one individual of Aquilaria sinensis and six
individuals of Gmelina chinensis were found missing.
During the monthly monitoring of
the in-situ preserved plant species of conservation importance in
November 2023, one individual of Aquilaria sinensis and one individual
of Enkianthus quinqueflorus
were newly observed and recommended being preserved in-situ.
Registration and measurement for two additional trees were conducted on 4
December 2023.
2.5.1
Preserved Plant Species of Conservation Importance
Monthly
monitoring of the in-situ preserved plant species of conservation
importance by the Qualified Personnel (QP) appointed under Contract 2 was
implemented in the reporting period. Health condition was considered fair
for the majority of the in-situ preserved plant
species of conservation importance, of which two individuals of Gmelina
chinensis could not be monitored as a result of unsafe access to the
locations, as recorded during the monitoring carried out on 20 December
2024.
Tree protection
zones for the in-situ preserved plant species of conservation importance
were demarcated. No injuries and/or damages to the individuals of the in-situ
preserved plant species of conservation importance were reported by the QP
since the previous monitoring events. Photographic record and tree
schedule of the preserved plant species of conservation importance monitoring
are provided in Annex H1.
The ET will
continue to monitor the implementation of monitoring of in-situ
preserved plant species of conservation importance.
2.5.2 Transplanted Plant Species of
Conservation Importance
Site visit to
the receptor site for the transplanted plant species of conservation importance
under Contract 2 was carried out on 20 January 2022 prior to the commencement
of transplantation works for the transplanted plant species of conservation
importance on 21 January 2022.
The
transplanted plant species of conservation importance were both certified as
dead trees by the QP on 15 June 2022 as no living signs were observed.
Replacement planting of new trees of the same species, or other species to the
satisfaction of the Project Manager, at the Contractors’ expense would be
deemed necessary in accordance with the conditions under the approved Detailed
Preservation and/or Translocation Plan for Plant Species of Conservation
Importance. Replacement planting of three (3) Aquilaria sinensis
were completed on 28 April 2023. One (1) individual was certified dead by
the QP as no living signs were observed on 26 July 2023. The removal of
the dead tree and replanting of one (1) individual of Aquilaria sinensis
were completed on 19 September 2023.
The
establishment period of two (2) individuals of Aquilaria
sinensis was ended on 27 April 2024 and one (1) individual of Aquilaria
sinensis was ended on 18 September 2024.
Quarterly
monitoring of three (3) individuals of Aquilaria sinensis were carried
out on 19 December 2024. All three (3) individuals of
the replacement planting trees were in fair health condition.
Photographic record and tree schedule of Aquilaria sinensis monitoring
are provided in Annex H2.
The
transplanted plant species of conservation importance were watered twice a week
during the establishment period to keep the soil moist except in days with
heavy rainfall. The ET will continue to monitor the implementation of
monitoring of in-situ preserved/ transplanted plant species of conservation
importance.
2.6
ECO-SHORELINE MONITORING
The
construction of vertical eco-shoreline, mangrove eco-shoreline and rocky
eco-shoreline has been substantially completed. Photographic record is
provided in Annex I.
The 2nd Progress report
of the eco-shoreline monitoring was submitted to AFCD and EPD on 23 December
2024, summarizing the monitoring results with key findings of the wet season
monitoring conducted in May 2024 and August 2024.
No eco-shoreline monitoring was
scheduled during the reporting period. Monitoring is conducted for
at least 3 years after the completion of eco-shoreline, twice in wet season and
twice in dry season, while ichthyoplankton and juvenile fish monitoring will be
conducted on a monthly basis covering May to August
for at least 3 years, in order to determine the effectiveness of the
eco-shoreline in accordance with the Updated EM&A Manual and Eco-shoreline
Implementation Plan.
2.7
Soft Shore
Ecological Monitoring
2.7.1
Monitoring Requirements
According to the Updated EM&A
Manual of the Project, post-construction soft shore ecological monitoring has
to be conducted quarterly at each survey location at Tung Chung Bay (TCB) and
Tai Ho Wan (THW) covering wet and dry seasons in the post-construction phase at
least for 2 year after completion of
construction. The soft shore ecological monitoring consisted of
qualitative walk-through surveys, quantitative transect surveys and
sedimentation rate monitoring at the accessible survey locations of TCB and THW.
For qualitative walk-through
surveys, the accessible shoreline of TCB and THW at each of the three shore
heights: 2 m, 1.5 m and 1 m above Chart Datum was surveyed, and organisms
encountered were recorded and their relative abundance noted. In particular, active search of horseshoe crabs and
seagrasses were conducted to confirm whether these species are present along
the sites.
For quantitative transect survey,
one 50 – 100 m horizontal (belt) transect (actual length subject to the site
conditions) was surveyed at each of the three shore heights: 2 m, 1.5 m and 1 m
above Chart Datum of each survey location. On each transect, five
quadrats (50 cm x 50 cm) were placed randomly in each transect to assess the
abundance and distribution of flora and fauna. For each quadrat, surface
layer to 5 cm depth was sieved and microbenthic organisms (e.g. crustaceans)
were recorded and identified. Density of organisms was expressed as
individuals / m2. Areas with seagrass were also recorded and
identified and other information, such as the percentage cover, were also
recorded. Sessile animals such as barnacles and oysters in each quadrat
were not counted but estimated as percentage cover on the rock surface.
All species of algae (encrusting, foliose and filamentous) were also identified
and recorded by estimating the percentage cover on the rock surface. All
organisms were identified to the lowest possible taxonomic level (at least Genus level). Species encountered outside the quadrat
but in the vicinity of survey transect were also recorded.
For sedimentation rate monitoring,
to avoid disturbance to the mudflat and nuisance to navigation, no fixed
marker/monitoring rod was installed at the monitoring stations. A high precision
Global Navigation Satellite System (GNSS) real time location fixing system was
used to locate the station in the precision of 1 mm, which is reasonable under
flat mudflat topography with uneven mudflat surface only at micro
level.
Measurements were taken directly on
the mudflat surface. The Real Time Kinematic GNSS (RTK GNSS) surveying
technology was used to measure mudflat surface levels and 3D coordinates of a
survey point. The RTK GNSS survey was calibrated against a reference
station in the field before and after each survey. The reference station
is a survey control point established by the Lands Department of the HKSAR
Government using professional surveying instruments such as total station,
level and geodetic global navigation satellite system. The coordinates
system is in HK1980 GRID system. The reference station was surveyed and
established by traditional land surveying methods using professional surveying
instruments such as total station, level and geodetic GNSS. The accuracy
was down to mm level and higher than the proposed RTK GNSS cm level so that the
reference control station has relatively higher accuracy. As the
reference control station has higher accuracy, it was set as true evaluation
relative to the RTK GNSS measurement. All position and height correction
were adjusted and corrected to the reference control station.
The precision of the measured
mudflat surface level reading (vertical precision setting) was within 10 mm
(standard deviation) after averaging the valid survey records of the XYZ HK1980
GRID coordinates. Each survey record at each station was computed by
averaging at least three measurements that are within the above specified
precision setting. Both digital data logging and written records were
collected in the field. Field data on station fixing and mudflat surface
measurement were recorded.
2.7.2
Monitoring Schedule for the Reporting Month
The schedule for soft shore
ecological monitoring during the reporting period is provided in Annex J1.

Quantitative and qualitative transect surveys were conducted on 5 December 2024
at TCB3, 9 December 2024 at TCB1, 18 December 2024 at TCB2, and 19 December
2024 at THW.
For the quantitative
transect surveys, a total of 12,794 individuals were recorded from all
transects at monitoring stations TCB1, TCB2, TCB3 and THW. The most
abundant group of intertidal soft shore communities recorded was gastropods,
with a total of 12,665 individuals (relative abundance of 99.0% and density of
844.3 individual m-2). The summary of the top three dominant
species at each shore height of each monitoring station and the complete list
of species and density recorded are presented in Annex J2. When compared with the results
obtained during the baseline monitoring as presented in the Baseline Monitoring
Report [5], there was no indication of a change in
the composition of intertidal communities recorded during the reporting period.
The mudflat
surface levels at the four selected monitoring stations in December 2024 and
the corresponding XYZ HK1980 GRID coordinates are presented in Table 2.8.
When compared with the results obtained during the baseline monitoring as
presented in the Baseline Monitoring Report, slight changes with <0.07 mPD of sediment levels are recorded for the monitoring
stations. The ET will continue to observe the trend of change in sediment
levels over time for further comparison and review.

Based on the post-construction monitoring
results, there was no evidence showing any significant difference in intertidal
communities when compared against the data obtained during baseline
monitoring. No action is thus required to be undertaken in accordance
with the Event and Action Plan presented in Annex J3. The ET will continue to observe the
change in density or the distribution pattern of horseshoe crab, seagrass and
intertidal soft shore communities taking into account
natural fluctuation in respect of the occurrence and distribution pattern.

the TCE Project during the period from 1 to 31 December 2024 in accordance with
the Updated EM&A Manual and the requirements of the Environmental Permit
(EP-519/2016). The environmental monitoring, site inspection,
environmental complaint handling and EM&A reporting in the temporary works
area in Area 113 used by MTRC will be covered by EM&A programme
of TUE and carried out by existing ET and IEC of TUE.
Air
quality (1-hour TSP), noise, compensation woodland, in-situ preserved plant species
of conservation importance, transplanted plant species of conservation
importance and post-construction soft shore ecological monitoring were carried
out in the reporting period.
The
monitoring results for air quality monitoring (1-hour TSP) complied with the
Action/ Limit levels in the reporting period.
No
exceedance of Action/Limit Level was recorded for construction noise monitoring
in the reporting period.
Water
quality monitoring was suspended in the reporting period.
Mangrove
eco-shoreline, rocky eco-shoreline and vertical eco-shoreline were
completed. No eco-shoreline monitoring was scheduled during the reporting
period.
Based on
the monitoring results for post-construction soft shore ecological monitoring,
there was no evidence showing any significant change in intertidal communities
when compared against the data obtained during baseline monitoring. The
ET will continue to observe the change in density or the distribution pattern
of horseshoe crab, seagrass and intertidal soft shore communities taking into account natural fluctuation in respect of the
occurrence and distribution pattern.
Post-planting
monitoring of the compensation woodland was carried out in the reporting month.
Monitoring
of the in-situ preserved plant species of conservation importance and
monitoring of the transplanted plant species of conservation importance were
carried out in the reporting period.
Environmental
site inspections were carried out during the reporting period.
Recommendations on remedial actions were given to the Contractors for the
deficiencies identified during the site inspections.
There
were no notification of summons or prosecution recorded in the reporting
period. No environmental complain was received in the reporting period.
The ET
will keep track on the construction works to confirm compliance of
environmental requirements and the proper implementation of all necessary
mitigation measures.
