1 Introduction

1.1 Background

In March 2005, the Project Proponent, Profit Point Enterprises Limited, acquired the development site at Wo Shang Wai in Yuen Long. An Environmental Impact Assessment (EIA) was then carried out and approved under the EIA Ordinance (EIAO), and the Environmental Permit (EP) for construction of the comprehensive development in Wo Shang Wai was first granted by Environmental Protection Department (EPD) on 9 September 2008 (EP-311/2008) and has been subsequently varied, with the current version (EP-311/2008/D) issued by EPD on 20 March 2013.

The Project involves the residential development and associated infrastructure and wetland restoration area and linear landscape area. The construction works under the Environmental Permit commenced on 12 May 2010. The site formation construction works of the Wetland Restoration Area (hereafter WRA) were completed on 15 November 2010, while the 30-month establishment period of the WRA was concluded in October 2012 – this indicated that planting works as scheduled in the approved Wetland Restoration and Creation Scheme (WRCS; Nov 2009) were completed, except along the western and southern boundaries where the planting is affected by the existing site boundary and noise barrier, and for which a Variation to Environmental Permit (EP-311/2008/C) to defer planting at the location was approved. This factor remains applicable in the current valid EP (EP-311/2008/D) which also includes specific mitigation measures to minimise certain identified noise impacts during the operation phase of the Project.

Mott MacDonald Hong Kong Ltd. (“MMHK”) has been commissioned by the Contractor, Heng Shung Construction Co. Ltd., to undertake the Environmental Team (ET) services to carry out environmental monitoring and audit (EM&A) for both pre-construction and construction phases of the Proposed Comprehensive Development at Wo Shang Wai, Yuen Long.

According to the EP Condition 4.6, the EM&A results on ecological aspects during the construction phase should be reported to the EIA Subcommittee of the Advisory Council on the Environment (ACE), EPD and Agriculture, Fisheries and Conservation Department (AFCD) on a biannual basis.

This is the 11^th Biannual EM&A report and it summarises the findings on EM&A results of ecological aspects during the period from 1 May 2015 to 31 October 2015. This report documents surveys and management activities conducted in the Survey Area and WRA from 1 May 2015 to 31 October 2015, which is based on ecological surveys and advices on management which were undertaken by the appointed Non-government Organisations (Green Power / Eco-Education & Resources Centre) during the reporting period.

1.2 Survey Area

Surveys were conducted within 500m of the Project area. The WRA was surveyed since early September 2010. The survey area and transect are provided in Figure 1.1.

1.3 EM&A Requirements on Ecological Impact

The EM&A programme requires environmental monitoring of ecology as specified in the approved EM&A Manual. A summary of ecological impact EM&A requirements is presented in Table 1.1:

2 Ecological Monitoring

2.1 Introduction

In accordance with the EM&A requirements, monitoring of birds, dragonflies and butterflies, and herpetofauna were carried out during the reporting period. In addition, monitoring of mammals was also conducted concurrently with other surveys and the results were reported although it is not required by the EM&A Manual. The dates of surveys are summarised in Appendix A.

2.2 Monitoring of Birds

Monitoring was undertaken following the survey methodology and frequency outlined in the EM&A Manual (Table 7-1). Since September 2010, monitoring included the newly formed cells to monitor faunal usage of this area. All bird species of conservation importance and/or wetland dependent were identified and enumerated. Flying birds were not recorded unless they were foraging and/or associated with the habitat (such as swifts). Further, notable bird observations during other surveys were also recorded.

Bird surveys were conducted on a weekly basis throughout the period. A total of 54 bird species were recorded in the Survey Area (excluding the WRA) in May 2015 to October 2015, 26 of which were species of conservation importance and/or wetland-dependence. A summary of survey data is provided in Appendix B.

A total of 59 species were recorded in the WRA in the survey periods, 34 of which were species of conservation importance and/or wetland-dependent species. The WRA has attracted a number of species of conservation interest, including Great Cormorant, Phalacrocorax carbo, Grey Heron, Ardea cinerea, Purple Heron, Ardea purpurea, Black-crowned Night Heron, Nycticorax nycticorax, Yellow Bittern, Ixobrychus sinensis, Black Kite, Milvus migrans, Pheasant-tailed Jacana, Hydrophasianus chirurgus, White-throated Kingfisher, Halcyon smyrnensis, Thick-billed Warbler, Iduna aedon, White-cheeked Starling, Spodiopsar cineraceus and Collared Crow, Corvus torquatus. Black-crowned Night Heron, Yellow Bittern, Pheasant-tailed Jacana, White-throated Kingfisher, Thick-billed Warbler and Collared Crow are listed by Fellowes et al. as of “Local  Concern” in 2002. Purple Heron and Black Kite are listed by Fellowes et al. as of “Regional  Concern” in 2002.  Great Cormorant, White-cheeked Starling and Grey Heron are listed by Fellowes et al. as of “Potential Regional Concern” in 2002. 

The three target species (i.e. Little Egret, Egtretta garzetta, Eastern Cattle Egret, Bubulcus coromandus and Chinese Pond Heron, Ardeola bacchus) were recorded in the WRA during regular survey.

Baillon's Crake, Porzana pusilla was also recorded in the WRA and it is a scarce passage migrant of Hong Kong. This indicated that the WRA provided suitable wetland habitats to  wetland-dependent passage migrant.

The fish ponds to the north of the WRA are at a greater distance from the residential portion and any disturbance impact(s) from the construction works would have first affected the WRA. Further, 34 bird species of conservation importance and /or wetland dependence, were observed using the site during survey period, including some bird species which are highly sensitive to disturbance and three target species (i.e. Little Egret, Eastern Cattle Egret and Chinese Pond Heron). Thus, the WRA is considered to be effective both in acting as a buffer against potential disturbance impacts from the construction site and in providing suitable wetland habitats at the fringe of the Deep Bay system.

2.3 Monitoring of Herpetofauna

Monitoring was undertaken following the survey methodology in the EM&A Manual. Day-time herpetofauna surveys were conducted once per month between May 2015 and October 2015. Further, notable herpetofauna observations during other surveys were also recorded.

Asian Common Toad, Bufo melanostictus and Gunther's Frog, Hylarana guentheri, were recorded in the survey area (excluding WRA) in the survey period. For reptile, Changeable Lizard, Calotes versicolor was observed in the survey area within the survey period.

Gunther's Frog, Hylarana guentheri, was recorded in the WRA in the survey period. No reptile species was recorded in the WRA within the survey period.  

A summary of survey data is provided in Appendix C.

2.4 Monitoring of Dragonflies and Butterflies

Monitoring of dragonflies and butterflies was conducted once per month in September 2015 and October 2015 and twice per month from May 2015 to August 2015. Further, notable dragonfly and butterfly observations during other surveys were recorded.

A total of five dragonfly species and one butterfly species were recorded using the ponds in the Survey Area (excluding WRA) in the reporting period. At the WRA, a higher diversity of dragonfly species (14 species) and butterfly species (7 species) were recorded. A summary of the survey findings is provided in Appendix C.

2.5 Monitoring of Mammals

Monitoring of mammals was conducted concurrently with other surveys. No mammal was recorded in the Survey Area (excluding WRA) within the reporting period.

One unidentified bat species was recorded in the WRA during regular survey. A summary of the survey findings is provided in Appendix C.

2.6 Monitoring of Water Quality

Monthly water quality monitoring continued during the reporting period. Monitoring parameters followed that in the EM&A Manual. pH of Cell 1 and  Cell 3 reached action level in May 2015; while water level of Cell 1, Cell 2 and Cell 4 reached action levels in May 2015; According to the ecological monitoring data, the low water level in the WRA attracted wetland-dependent species including Great Cormorant, Phalacrocorax carbo, Grey Heron, Ardea cinerea, Purple Heron, Ardea purpurea, Black-crowned Night Heron, Nycticorax nycticorax, Yellow Bittern, Ixobrychus sinensis, Pheasant-tailed Jacana, Hydrophasianus chirurgus and White-throated Kingfisher, Halcyon smyrnensis. As the low water level attracts wetland-dependent birds, the existing water level will be maintained and monitored regularly. Monitoring data are presented in Appendix D. Locations for the monitoring of water quality for the ecological monitoring are shown in Figure 1.2.

3 Ecological Issues

3.1 Vegetation Management

Removal of exotic vegetation in all cells was undertaken; these included but not limited to Ipomoes sp., Mikania sp., Mimosa sp., Pennisetum sp. and Typha sp..

Vegetation management activities undertaken at the site primarily involved watering of plants, tree pruning, weeding and grass cutting.

3.2 Wildlife Management

Golden Apple Snails were removed on an “as-seen” basis.

All red fire ant nests were treated with approved pesticide and covered with overturn baskets for a week. All pesticide used were in powder form and the pesticide usage was confined to Fire Ants’ nest found on terrestrial area which were further away from the Cells to prevent the contamination of water. All treated fire ant nests were inactive within one week of treatment.

Preliminarily actions have been taken to increase the WRA utilization by birds. The mitigation actions are:

1. Lowering the water level;

2. Restocking the Cell in the WRA;

3. Installing flooding platform; and

4. Controlling the vegetation.

The first two measures aim to increase the foraging area and food sources for the target species respectively. The third measure aims to increase foraging ground for the target species. According to Horiuchi et al (2007), floating platform can gather fish in the pond and this provides opportunities for the target species to prey for the fish which can be use as a fishing platform. The fourth measure aims to maintain suitable habitat for target species.

4 Summary of Wetland Restoration Area Performance

4.1 Summary of Findings

Ecological monitoring between 1 May 2015 and 31 October 2015 was carried out following the survey methodology and frequency outlined in the EM&A Manual.

Summary of ecological monitoring in the Survey Area and WRA between May 2015 and October 2015 (Table 4.1):

Table 4.1:       Summary of Ecological Monitoring in WRA and Survey Area

Species	Number of species recorded in Survey Area (excluding WRA)	Number of species recorded in WRA
Birds (total)	54	59
Birds (of conservation importance and/or wetland-dependence)	26	34
Amphibians	2	1
Reptiles	1	0
Mammals	0	1
Dragonflies	5	14
Butterflies	1	7

A total of 59 bird species, 1 mammal species, 14 dragonfly species and 7 butterfly species were recorded in the WRA, including 34 bird species of conservation importance and/or wetland-dependence, while all dragonfly species are wetland-dependent. These findings indicate that the WRA is supporting wetland-dependent birds and other species of conservation importance. A list of the bird species recorded at the WRA since completion of site formation is provided in Appendix B (Table B4 to B6).

With the completion of planting as scheduled in the approved Habitat Creation and Management Plan (HCMP) in August 2012, establishment work at the WRA is considered complete (except along the western and southern boundary where the planting is affected by the existing site boundary and noise barrier, and for which an approved Variation to Environmental Permit (EP-311/2008/D) to defer planting at the location applies), and the 30 month establishment period concluded in October 2012. A review of the performance of the WRA during the review period in terms of target species attraction is provided in Section 4.2 below.

It should be noted that the high planting density was intended to ensure a rapid establishment of the site prior to occupation intake, and not intended to be maintained as a long-term tree density at the WRA. It is a standard arboricultural practice to apply appropriate horticultural/arboricultural maintenance methods in the subsequent five or six years after initial planting to remove less desired specimens to facilitate the successful growth of those which are of higher landscape and/or ecological value. Further, some fine tuning of planting locations and tree/shrub mix is required in order to fulfill the design intent of the habitat structure at WRA after reviewing the site configuration following site formation. Vegetation management hereafter should largely consist of maintenance of planted trees and shrubs for the creation of suitable habitats for target species and long-term habitat structure of the site.

4.2 WRA Performance for Bird Target Species

The provision, maintenance and operation of a WRA are a requirement under the Environmental Permit for compensation for predicted ecological impacts to species of conservation importance. Three bird target species were identified during the EIA process; they are Little Egret, Eastern Cattle Egret and Chinese Pond Heron. Target levels of these species are the annual mean number recorded during the Baseline Ecological Monitoring (i.e. a mean of 5.5 Little Egret, 1.3 Eastern Cattle Egret and 1.3 Chinese Pond Heron over a 12 month period) thus, the ecological impact of the project to the species concerned is considered to have been fully compensated when the target level for each of the three species is achieved. Whilst further discussion and agreement regarding the target level is yet to be undertaken with the relevant Government departments prior to the operation of the WRA, the proposed level offers a clear reference to the effectiveness of the mitigation measures. According to the approved Wetland Creation and Restoration Scheme (Nov 2009, hereafter WCRS), the WRA is anticipated to be fully operational after an establishment period of 2.5 years (30 months).

Table 4.2:       Annual Mean of the Three Bird Target Species Recorded at the WRA between May 2010 and Oct 2015

Common Name	Scientific Name	Conservation Status ^(2)	Baseline Annual Mean ^(3)	May 10-Apr 11	May 11-Apr 12	May 12-Apr 13	May 13-Apr 14	May 14-Apr 15	(Reporting period) May 15 – Oct 15*
Chinese Pond Heron	Ardeola bacchus	PRC, (RC)	1.3	0.2	2.7	1.3	1.9	2.0	2.1
Little Egret	Egretta garzetta	PRC, (RC)	5.5	1.6	1.0	0.9	2.3	2.0	1.5
Eastern Cattle Egret	Bubulcus coromandus	(LC)	1.3	0.0	1.2	0.0	0.1	0.0	0.1

Note:      

(1) Values in bold indicate that the Target Level was achieved.

(2) Conservation Status follows that of Fellowes et. al. (2002). See Appendix B (Table B3).

(3) Annual mean number recorded during Baseline Ecological Monitoring.

*    The mean number of the target species was calculated in annual basis.

Based on Table 4.2 above, the target level of the Chinese Pond Heron was achieved between May 2015 and October 2015 while the target levels for Little Egret and Eastern Cattle Egret was not achieved.

As the Proposed Comprehensive Development at Wo Shang Wai is still under construction phase, it is considered acceptable. According to the ecological monitoring data of the survey area (excluding the WRA), Eastern Cattle Egret was observed only in one fifth of the regular ecological survey (i.e. 6 out of 29) and the annual mean of the Eastern Cattle Egret of the survey area (excluding the WRA) is 2.1 birds per survey, the results indicated the number of Eastern Cattle Egret in the whole area was low and the low number of Eastern Cattle Egret in the WRA is considered acceptable.

In addition, although the target levels for Little Egret and Eastern Cattle Egret have not been achieved between May 2015 and October 2015, the WRA continues to attract wetland dependent species. Among all the wetland dependent species, Great Cormorant, Phalacrocorax carbo, Grey Heron, Ardea cinerea, Purple Heron, Ardea purpurea, Black-crowned Night Heron, Nycticorax nycticorax, Yellow Bittern, Ixobrychus sinensis, Black Kite, Milvus migrans, Pheasant-tailed Jacana, Hydrophasianus chirurgus, White-throated Kingfisher, Halcyon smyrnensis, Thick-billed Warbler, Iduna aedon, White-cheeked Starling, Spodiopsar cineraceus and Collared Crow, Corvus torquatus. Black-crowned Night Heron, Yellow Bittern, Pheasant-tailed Jacana, White-throated Kingfisher, Thick-billed Warbler and Collared Crow are listed by Fellowes et al. as of “Local Concern” in 2002. Purple Heron and Black Kite are listed by Fellowes et al. as of “Regional Concern” in 2002.  Great Cormorant, White-cheeked Starling and Grey Heron are listed by Fellowes et al. as of “Potential Regional Concern” in 2002.   The presence of these wetland-dependent species indicates that the WRA was effective in providing habitat suitable for species of conservation interest.

4.3 Conclusions

A total of 121 bird species have been recorded within the WRA since completion of site formation. Of the 121 species, 76 were species of conservation importance and/or wetland dependence – indicating that the WRA provides suitable habitats for these species despite the construction work within the residential portion of the Project Site.

The site continuously attracts bird species of conservation importance, indicating that the WRA not only provides a buffer for potential disturbance during construction phase, but also a valuable habitat for wetland dependent species and species of conservation importance.
