Abstract
The history of change in the extent and floristic diversity of the mangrove community in Taiwan is viewed in the context of rapid economic development. The example shows loss of both species and habitat before the emergence of a concern for conservation and improvement of environmental quality. Mangroves in Taiwan stand near the limit of their range; individual plants are stunted and communities have fewer species than those in lower latitudes. The most extensive and richest natural mangrove communities once existed along the coasts of southwestern Taiwan sheltered by offshore bars. The whole western coast is subject to rapid natural progradation which, coupled with human manipulation in the form of reclamation of mud flats and canalization of drainage, has produced a highly artificial intertidal zone. Old-growth mangroves have been almost completely replaced and two species have become locally extinct in Taiwan. The traditional practice of growing mangroves to reduce erosion has been largely discontinued. Tidal mud flats have been planted in an effort to hold sediments, and these make up a very significant proportion of its total extent in Taiwan. The question of mangrove preservation in Taiwan arose in 1980 and represents an important turning point for the environmental movement. It is argued that mangroves have special qualities which recommend them as models for explaining general justification for environmental protection. © 1992.
