All
the fung shui forests surveyed were located behind,
or close to, villages and were generally well
preserved. The majority of the fung shui forests
surveyed were small in size and subject to little
or no human disturbance. Many of the fung shui
forests surveyed showed a closed canopy and attained
a canopy height of between 12 - 20 m. Canopy height
as high as 25 m was recorded for the fung shui
forest at Yim Tso Ha (Site 6a). Dense understorey
growth was generally observed for most of the
surveyed habitats. The protected plant species
Pavetta hongkongensis were recorded in some of
the survey sites (including North Lantau (Sites
1a and 1b), Lam Tsuen (Site 5a), Yim Tso Ha (Site
6a) and Sai Kung areas (Sites 7b, 7d and 8a)).
Rare species Pygeum topengii and Xylosma longifolium
were observed at Lam Tsuen (Site 5b) and Yim Tso
Ha (Site 6b), respectively (see Table G1 of Annex
G for details).
Most
of the survey sites are considered to have a high
ecological value (ie same as their indicative
ecological value). Two patches (Sites 3b and 4b)
have been downgraded from high to medium ecological
value as their understorey vegetation has been
cleared and the areas become a playground whilst
their canopy layers remain intact (Table 7.1a).
While most of the fung shui forests remain intact
or only slightly disturbed by development, there
are areas where disturbance to the habitat (due
to development) is great and have resulted in
degradation of habitat quality.
