Ecological value of three of the sandy shore sub-sites were upgraded based on the results obtained from field surveys (Table 7.1n). The high-valued sandy shores were remote and subjected to little or no human disturbance. These habitat communities were relatively intact and composed of higher species diversity and abundance than other sandy shores in Hong Kong. The other surveyed shores, which were of medium ecological value, supported lower species diversity and abundance. Most of these sites are away from urban areas and thus under little or no development or pollution pressure (see Table G14 of Annex G for details).
