Importance of vegetationLinks

Vegetation covers some 60% of the land surface in Hong Kong. It offers diverse habitats and food for the local fauna (animals). It also helps improve air and water quality, prevent water runoff and soil erosion.

Knowledge of vegetation is important to numerous scientific (and other) disciplines, such as biology, ecology, forestry, agronomy, hydrology, meteorology, and even some social sciences. Very often, vegetation analyses may offer information for a diverse array of questions. For example, an agricultural specialist might use satellite images of vegetation to monitor crop production while a sociologist could use the same images to study land use practices. Foresters could look at forest extent to estimate timber amount while ecologists might need to use similar spatial areas in studies of nutrient cycling.
