The results of applying the ranking system to the data collected under this baseline survey, and under the SUSDEV 21 Environmental Baseline Survey, are plotted on the habitat map to indicate which areas have high levels of conservation value. Through customized plotting routines, the map can be produced to show any one or combination of the following:

• Areas of High Ecological Value

• Areas of Medium Ecological Value

• Areas of Low Ecological Value

• Areas of Negligible Ecological Value

• Areas of Heritage Value

• Areas of Recreational Value

• Areas of Landscape Value

• Areas of Specified Conservation Value

The final category (Areas of Conservation Value) can be defined based on an ad hoc user definition of the areas to be plotted. For example, the user may specify the conservation value map to show:

• all category "A" areas only; or

• all areas with categories ending in "+++" only;. or

• all category "A" areas with at least 2 "+"s, etc.

This plotting system will have the benefit of allowing the user to select the particular conservation value components of greatest interest for presentation. It thus avoids forcing all users to employ a single definition of conservation value. Nevertheless the system concentrates on ecological value, which is the focus of this baseline survey, and will therefore readily support application of the indicators involving areas of Hong Kong with high ecological value.
