Table 5.4d Ecological Value of Sandy Shore and Artificial Seawall in the Assessment Area

Criteria	Sandy Shore	Artificial Seawall
Naturalness	The small sandy shore near Hong Kong Country Club is relatively free from physical modifications but is affected by water pollution to some extent.	Artificial, constructed habitat.
Size	Area of this habitat within assessment area is approximately 0.3ha.	Area of this habitat within assessment area is approximately 1ha.
Diversity	Very low.	Typical of other relatively sheltered shores in Hong Kong.
Rarity	No significant records.	One faunal species (Pacific Reef Egret, Egretta sacra) of conservation importance recorded from artificial seawall.
Re-creatability	Habitat is re-creatable	Not applicable.
Fragmentation	Moderate-High. Sandy shores form a small portion of intertidal habitat in the assessment area.	Not applicable.
Ecological linkage	The sandy shore habitat falls partially within CPA.	Habitat is not structurally or functionally linked to any high ecological value resources.
Potential value	Low.	Low.
Nursery ground	No record of significant nursery or breeding ground was found in the survey.	No record of significant nursery or breeding ground was found in the survey.
Age	Not applicable.	Seawalls of Tai Shue Wan are generally more than 10 years old.
Abundance/ Richness of Wildlife	Very low.	Moderate. Typical species of similar composition and abundance as other sheltered shores in Hong Kong.
Ecological value	Low.	Low
