   Lai Chi Wo
    Site Description

Nestled in the hills of the far northeastern corner of Hong Kong. Lai Chi Wo houses the largest mangrove trees, Heritiera littoralis, in the territory. These trees also support numerous gigantic climbers, Derris trifoliata, which cross and climb from one tree to another. Together with the huge interweaving buttress roots, it forms a magnificent patch of primitive coastal forest, which cannot be found elsewhere in Hong Kong. Just beyond this mangrove forest, there is a highly biodiverse mudflat. Of the 5 known seagrass species in Hong Kong, Zostera japonica and Halophila ovalis can be found in the mudflat and are ecologically important in playing a key role in providing food and shelter for many juvenile coastal creatures, including fish fry and crab and shrimp larvae.

    Site Protection

The area is listed as SSSI.

Disembark at Wu Kau Tang and walk along Fan Shui Au for about 2 hours to reach Lai Chi Wo.

    Survey method

Surveys were undertaken during low tide period (i.e. tidal level < 1.2m).  The mangrove site was first identified from aerial photo; subsequently, ground truthing was conducted to delineate the exact boundary and extent of the mangrove to determine the total area.  During each survey, mangrove species were observed and recorded on site. Survey of mangrove-associated fauna was standardized by dividing each site into three zones (upper, middle and lower shore) followed by fauna searching in each zone for 15 minutes.
