EXECUTIVE SUMMARY

1. This Land-based Dolphin Behaviour and Movement Monitoring Impact Phase Monitoring Report is prepared by Cinotech Consultants Ltd. for the project “Contract No. HY/2011/09 – Hong Kong-Zhuhai-Macao Bridge Hong Kong Link Road – Section between HKSAR Boundary and Scenic Hill” (hereinafter called the “Contract”). This report documents the findings of Land-based Dolphin Behaviour and Movement Monitoring conducted in March, April and July 2013.

Land-based Dolphin Behaviour and Movement Monitoring Impact Phase Monitoring Progress

2. A summary of the monitoring activities in the reporting period is listed in Table I below:

Table I Summary Table for Monitoring Activities in the Reporting Month

Parameter(s)	Date(s)
*Land-based Dolphin Behaviour and Movement Monitoring	With Bored Piling Activities: 18^th, 19^th, 20^th, 21^st, 22^nd, 23^rd, 25^th, 27^th, 28^th March 2013 1^st, 2^nd, 4^th, 5^th, 7^th, 8^th, 9^th, 10^th and 11^th April 2013 8^th, 9^th, 10^th, 11^th, 12^th, 13^th, 15^th, 17^th, 18^th, 19^th, 23^rd, 24^th and 29^th July 2013

Remark: *Dolphin-related monitoring was conducted in the reporting month. According to the EM&A Manual for HKLR, the dolphin-related monitoring was conducted during the bored piling activities (e.g. installation of permanent casting for bored piling activities) which presented in Appendix A.
