2.4.6 Monitoring Schedule for the Reporting Month

Dolphin monitoring was carried out on 5, 11, 17 and 25 March 2014 (Appendix F).

2.4.7 Results and Observations

A total of 296.83 km of survey effort was collected, with 89.0% of the total survey effort being conducted under favourable weather conditions (i.e. Beaufort Sea State 3 or below with good visibility) during the February¡¦s surveys. Among the two areas, 117.30 km and 179.53 km of survey effort were collected from NEL and NWL survey areas respectively. The total survey effort conducted on primary and secondary lines were 211.71 km and 85.12 km, respectively. The survey efforts are summarized in Appendix K.

A total of 14 groups of 43 Chinese White Dolphin sightings were recorded during the two sets of surveys in March 2014. All sightings were made in NWL during the two sets of surveys in March, with no dolphin being sighted at all in NEL. All except two sightings were made on primary lines during on-effort search, and none of the dolphin groups was associated with operating fishing vessel.

The majority of these dolphin sightings in March 2014 were made at the northwestern portion of NWL survey area, especially to the north of Lung Kwu Chau. Another two sightings were made at the north of the airport and between the River Trade Terminal and airport platform respectively. The distribution of dolphin sightings during the reporting month is shown in Figure 2.5.

Encounter rates of Chinese White Dolphins are deduced from the survey effort and on-effort sighting data made under favourable conditions (Beaufort 3 or below with good visibility) in March 2014 with the results presented in Tables 2.12 and 2.13.

Note: Overall dolphin encounter rates (sightings per 100km of survey effort) from all four surveys are conducted in March 2014 on primary lines only as well as both primary lines and secondary lines in Northeast and Northwest Lantau

The average group size of Chinese White Dolphins in March 2014 was 3.07 individuals per group, which was lower than the previous three months of dolphin monitoring. Most dolphin groups were composed of 1-3 animals, with only one large group of 13 animals sighted near Lung Kwu Chau. Detailed results of dolphin monitoring in this reporting month are presented in Appendix K.

During this month of dolphin monitoring, no unacceptable impact from the construction activities of the TM-CLKL Southern Connection Viaduct Section on Chinese White Dolphins was noticeable from general observations

Due to monthly variation in dolphin occurrence within the Study area, it would be more appropriate to draw conclusion on whether any unacceptable impacts on dolphins have been detected related to the construction activities of the TM-CLKL Southern Connection Viaduct Section in the quarterly EM&A reports, where comparison on distribution, group size and encounter rates of dolphins between the quarterly impact monitoring period and baseline monitoring period will be made.

2.4.8 Marine Mammal Exclusion Zone Monitoring

Daily 250 m marine mammal exclusion zone monitoring was undertaken during the period of dredging activities being undertaken.  No sighting of Indo-Pacific humpback dolphin Sousa chinensis were recorded in March 2014 during the exclusion zone monitoring.

2.4.9 Marine Bored Piling Monitoring

Marine bored piling monitoring programme for dolphins (ie Land-based Theodolite Tracking, Underwater Noise Monitoring and Acoustic Behavioural Monitoring) was undertaken since 3 March 2014. No sightings of Indo-Pacific humpback dolphins Sousa chinensis were recorded during the bored piling monitoring in March 2014. The monitoring schedule for bored piling monitoring in March 2014 is presented in Appendix F.

2.5 Coral Monitoring

No Post-Translocation Monitoring Exercise was conducted in the reporting month in March 2014.

2.6 EM&A Site inspection
