2.3       WATER QUALITY Monitoring

No monitoring event for impact water quality monitoring was conducted at all designated monitoring stations during the reporting period.  Water quality monitoring has been suspended since 3 October 2023 as all reclamation works and marine construction activities have been completed.

2.4       COMPENSATION WOODLAND MONITORING

Compensation woodland planting under Contract 2 was completed on 30 September 2022.  With the approval from EPD on the monitoring proposal in August 2023, quarterly post-planting monitoring for compensation woodland was commenced in September 2023.   Quarterly post-planting monitoring for the compensation woodland was carried out on 10, 13, 18 and 29 September 2024.  Photographic record of the compensation woodland planting is provided in Annex G.

2.5       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 27 September 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.

Quarterly monitoring of two (2) individuals of the Aquilaria sinensis and monthly monitoring of the replacing planting of one (1) individual of the Aquilaria sinensis were carried out on 24 September 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.

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.

2.7.3   Results and Observations

Post-construction soft shore ecological monitoring was conducted at three (3) monitoring locations at Tung Chung Bay (TCB), situated in the eastern side (TCB1), southern side (TCB2) and western side (TCB3) as well as one (1) monitoring location at Tai Ho Wan (THW) as shown in Figure 2.3 during the reporting period.  Representative photographs taken during the impact monitoring are presented in Figure 2.4.

For qualitative walk-through surveys, horseshoe crabs and intertidal soft shore communities were recorded during the post-construction monitoring.  The survey results for each monitoring location are summarized in Table 2.7 below and detailed in Annex J2.

Note:

a   Quantitative and qualitative transect surveys were conducted on 2 September 2024 at THW, 16 September 2024 at TCB3, and 27 September 2024 at TCB1 and TCB2.

 

For the quantitative transect surveys, a total of 10,838 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 10,645 individuals (relative abundance of 98.2% and density of 709.7 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 September 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 <0.06 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.
