    Abstract

    Changes in the structure and composition of the carabid fauna were studied in a former intertidal saltmarsh and sandflat of the Markiezaat area (The Netherlands) after this became embanked. Nine years of study revealed a rapid replacement of the original halophytic plant community and halobiontic carabid community by a mesophytic graminous plant community and associated carabid assemblage, consisting of halotolerant or halophobe species. Desalination and drainage explains most of the variance after Canonical Correspondance Analysis and are considered to be the main driving forces of succession. It is shown however, that a muck of the reason for change might derive from microclimatical and structural changes in vegetation.
