Long Valley is the largest remaining area (33 hectares) of freshwater wetland in Hong Kong, bounded
on the west and northwest by the River Beas and on the east by the River Sutlej (Fig. 8.85(a)). The settlement
of Yin Kong is to the south; there is development to the southeast adjacent to the River Sutlej and the
village of Ho Sheung Hueng is to the northwest on the opposite side of the River Beas. The ecological
habitats of Long Valley Wetland are created by the agricultural activity, and the area as a whole can be
regarded as un-fragmented (Fig. 8.85(b)).
This wetland is of high ecological importance with a high diversity of birds. Over 200 different species
have been recorded, 29 of which are of conservation importance. Of particular concern is the Greater
