Introduction
According to
findings of the Northwest New Territories (NWNT) Traffic and Infrastructure
Review conducted by the Transport Department, Tuen Mun Road, Ting Kau Bridge, Lantau Link and North Lantau
Highway would be operating beyond capacity after 2016. This forecast has been based on the
estimated increase in cross boundary traffic, developments in the NWNT, and
possible developments in North Lantau, including the
Airport developments, the Lantau Logistics Park (LLP)
and the Hong Kong – Zhuhai – Macao Bridge (HZMB). In order to cope with the anticipated
traffic demand, two new road sections between NWNT and North Lantau – Tuen Mun
– Chek Lap Kok Link
(TM-CLKL) and Tuen Mun
Western Bypass (TMWB) are proposed.
An
Environmental Impact Assessment (EIA) of TM-CLKL was prepared in accordance
with the EIA Study Brief (No. ESB-175/2007) and the Technical Memorandum of the Environmental
Impact Assessment Process (EIAO-TM). The EIA Report was submitted under the
Environmental Impact Assessment Ordinance (EIAO) in August 2009. Subsequent to the approval of the EIA
Report (EIAO Register Number AEIAR-145/2009), an Environmental Permit
(EP-354/2009) for TM-CLKL was granted by the Director of Environmental
Protection (DEP) on 4 November 2009, and two applications of EP variation,
EP-354/2009/A and EP-354/2009/B, were granted on 8 December 2010 and 28 January
2014, respectively.
Pursuant to Condition
2.6 of the EP, the Detailed Coral Translocation Methodology ()
has been submitted on 17 October 2013 and was subsequently approved by
the DEP for this Contract. Coral
translocation was undertaken for the coral colonies at Pillar Point from 21-23
October 2012 prior to construction of the Northern Landfall on November 2013 in
order to reduce the potential marine ecological impacts by translocating
movable coral colonies to the receptor site at Yam Tsai Wan. In accordance with the Detailed Coral
Translocation Methodology, the translocated coral
colonies as well as the tagged natural coral colonies at the receptor site will
be monitored once every three (3) months for a period of 12 months after the
coral translocation exercise.
The purpose of
this First Quarterly Post-Translocation
Coral Monitoring Report is to report findings of the First Quarterly Post-translocation
Coral Monitoring which is undertaken at the receptor site, Yam Tsai, Wan, to
monitor the updated status of translocated corals
from the donar site at Pillar Point. The results of the post-translocation
monitoring are reviewed with reference to findings of the pre-translocation
survey in order to assess any observable changes in status of the translocated coral colonies. Post-translocation monitoring results are
also evaluated against Action and Limit Levels which are based on recorded changes
in percentage of partial mortality of the corals.
The remainder
of the report is structured as follows:
Section 2:
First Quarterly Post-Translocation Coral Monitoring – Details
the methodology and results of the First Quarterly Post-translocation Coral
Monitoring.
Section 3: Schedule
of Quarterly Post-translocation Coral Monitoring – Details
the tentative schedule of the subsequent Quarterly Post-translocation Coral
Monitoring.
Section 4:
Conclusion – Concludes the First Post-translocation Coral
Monitoring results for the Contract.

First
quarterly post-translocation Coral Monitoring
2.1
Post-translocation
Monitoring Methodology
Pre-translocation surveys were undertaken at the donar
site of Pillar Point and receptor site of Yam Tsai Wan to collect baseline data
on translocated coral colonies from Pillar Point and
natural coral colonies at Yam Tsai Wan during the coral translocation exercise
in October 2013. During the
pre-translocation survey, twenty-three (23) colonies of Guaiagorgia sp., twenty-four (24) colonies of Oulastrea crispate and nine (9) colonies of Balanophyllia
sp, which were successfully translocated
from Pillar Point to Yam Tsai Wan, were tagged for monitoring. In addition to the translocated
coral colonies, ten (10) colonies of Guaiagorgia sp., ten (10) colonies of Oulastrea crispata and six (6) colonies of Balanophyllia sp. were tagged at the receptor site.
Each of the tagged coral colonies was identified at least to genus
levels and photographed. The
following data were recorded for each tagged coral colonies during the pre-translocation
survey:
·
Genus/ Species;
·
Size (Maximum diameter/
height);
·
Mortality (%);
·
Bleaching (%); and,
·
Sediment (%).
During the
Post-translocation Coral Monitoring, the tagged coral colonies will be
re-visited for monitoring using the same methodology as the pre-translocation
survey. Photographic records of the
translocated and natural coral colonies will be taken
by maintaining the same aspect and orientation as photographs taken for the
pre-translocation surveys as far as possible. The adoption of the same monitoring method would allow for direct
comparison of baseline pre-location data with the post-translocation monitoring
data in order to determine any changes in conditions of corals. The general
environmental conditions including weather, sea and tidal conditions of the
coral receptor site will also be monitored.
The results of
the post-translocation monitoring will be reviewed with reference to findings
of the pre-translocation surveys undertaken at the donar
and receptor sites. If observations
of any die-off / abnormal conditions of the translocated
corals are made during the post-translocation monitoring, the ET should inform
the Contractor, Independent Environmental Checker (IEC) / Environmental Project
Office (ENPO), and AFCD, and liaise with AFCD to investigate any mitigation measures
needed.
Post-translocation Coral Monitoring results will be evaluated against
Action and Limit Levels which is based on the recorded changes in the
percentage of partial mortality of the corals (Table 2.1). If the
defined Action Level or Limit Level for coral monitoring is exceeded, the
actions set out in Table 2.2 will be
implemented.

for Post-Translocation Coral Monitoring
|
Parameter
|
Action Level Definition
|

|
|
Mortality
|
If during Impact Monitoring a 15% increase in the
percentage of partial mortality on the corals occurs at more than 20% of the translocated coral colonies that is not recorded on the
original corals at the receptor site, then the Action Level is exceeded.
|
If during Impact Monitoring a 25% increase in the
percentage of partial mortality on the corals occurs at more than 20% of the translocated coral colonies that is not recorded on the
original corals at the receptor site, then the Limit Level is exceeded.

The species, size, mortality percentage, bleaching percentage and
percentage of sediment cover of the translocated
coral colonies and natural coral colonies recorded during the First Quarterly
Post-translocation Coral Monitoring surveys are summarized in Tables 2.4 & 2.5. Photographic records taken during the
First Quarterly Post-translocation Coral Monitoring are shown in Annex A.
Findings of the First Quarterly Post-translocation Monitoring indicated
that the Action or Limit Levels for coral monitoring were not exceeded as
increase in percentage of partial mortality was not detected for both the
tagged translocated and natural coral colonies when
comparing to the pre-translocation dataset (Tables
2.4 & 2.5). As such, it is
considered not necessary to undertake any action in accordance with the Event
and Action Plan.
Overall, findings of the First Quarterly Post-translocation Monitoring
did not appear to indicate any deterioration in the general health conditions
of the translocated and natural coral colonies at the
receptor site during this quarterly period.

Conclusion
The First Quarterly Post-Translocation Coral Monitoring has been carried
out on 17 January 2014 at the receptor site, Yam Tsai Wan, as per the
requirements stipulated in the Detailed
Coral Translocation Methodology.
During the monitoring, 56 translocated coral
colonies and 26 natural coral colonies were re-visited and monitored at the
receptor site, Yam Tsai Wan. The
conditions of the translocated and natural coral
colonies during the First Quarterly Post-Translocation Coral Monitoring are
compared with the pre-translocation conditions which were recorded during the
coral translocation exercise in October 2013.
Action and Limit Levels for the partial mortality of tagged corals were
established based on the Pre-translocation Coral Monitoring results. No exceedances
of the Action and Limit Levels were identified during the First Quarterly
Post-Translocation Coral Monitoring on 17 January 2014. There thus did not appear to be any
deterioration in the general conditions of the translocated
and natural coral colonies at the receptor site, Yam Tsai Wan.
Overall, the coral translocation exercise is considered to be undertaken
successfully as the translocated corals did not show
any sign of deterioration in condition at the receptor site during this
quarterly survey.
Findings of future Post-Translocation Coral Monitoring surveys will be
presented in the subsequent Post-Translocation Coral Monitoring Reports in
order to determine any observable changes in status of the translocated
coral colonies. In the event that
deterioration in conditions of the translocated
corals is identified, monitoring would allow for implementation of appropriate
remedial actions to mitigate such changes in condition.
