Appendix 4 List of LCTs and Treatment Methods Used to Generate PLCM

LCT Code   Interim Code Landscape Character Type (LCT)
Rh(k)1  Grassy peaks and ridges


Description
These landscapes comprise the highest upland and peaks in Hong Kong. They are remote and exposed upland landscapes, above circa 300mPD, characterised by rocky precipitous crags, peaks and ridges. Predominantly grass-covered, they contain small areas of scrub and woodland developing in sheltered ravines and valleys, e.g. Sunset Peak, Lantau Peak.

Rules defining this LCT in the PLCM are
selecting areas that are non-developed, above 300mPD and primarily grass covered

Data gaps and limitations:
None

LCT Code   Interim Code Landscape Character Type (LCT)
Rh(k)2  Scrub-covered peaks and ridges

Description
Like the above, these are remote upland landscapes above 300mPD. However because these uplands occur in slightly more sheltered locations, there is sufficient shelter to allow the development of scrub and limited woodland vegetation, e.g. Tai Mo Shan.

Rh(b)1  Grassy undulating uplands and hillsides


Description
These are exposed hillside landscapes on the mid-slopes of upland areas occurring below 300mPD. However, their elevated location results in a remote and rugged character and they are often fissured by gullies and ravines. Because of their exposed locations, scrub or woodland has difficulty developing, leaving a covering of grass and rocky outcrops, e.g. uplands above Fan Lau

Description
These are expansive hillside landscapes on the mid-slopes of upland areas occurring below 300mPD. and are common across Hong Kong. Because of their reasonably sheltered locations, they have a covering of scrub or scrub and grass with some woodland in more sheltered gullies, but possess remote and tranquil character\, e.g. uplands along Clearwater Bay Peninsula.

Description
These are landscapes of the central areas of older villages in outlying areas, which have developed a certain critical mass and diversity of uses, to become small townships. Typically found in coastal locations, they are characterised by their extent, narrow streets, tight street pattern, low- and medium-rise buildings, mixed retail and residential uses and limited street tree or open space vegetation, resulting in a small scale and contained ˇĄtownˇ¦ landscape, unusual in Hong Kong, e.g. Sai Kung, Stanley.

Description
These landscapes were once isolated villages in their traditional rural setting, which have grown considerably in recent years. Modern village policy housing and the encroachment of urban fringe development have changed the spatial relationship of the village as well as its relationship to its setting. They are characterised by residual historic buildings with considerable modern infill, loss of surrounding agricultural fields, which have been replaced by urban fringe, village policy housing extending out into the countryside and rural fringe uses or infrastructure development. The result is a rather incoherent and dispersed village landscape, Shap Pat Heung.
