On Santa Catarina Island in southern Brazil, mangrove systems are found along about 14.7% of this coast. These areas, although declared by legislation as 'Permanent Preservation Areas', have been undergoing a process of progressive and irreversible destruction for the past 50 years. At present the most damaged mangrove is that of Itacorubi, surrounded by the city of Florianopolis, a state capital of approximately 200,000 inhabitants. This paper discusses the ecological costs of urban expansion.
