    Abstract

    Urbanization is a leading cause of species loss in the United States because of habitat destruction and fragmentation. Wetlands can be affected by urbanization and the condition of wetlands can be compared across land use categories. Cypress domes are isolated wetlands dominated by cypress (Taxodium distichum) and often remain in urban areas. The purpose of this study was to quantify the effects of urbanization on cypress dome number, size and spatial pattern through two decades of rapid urbanization in Orlando, Florida, a large city in the southeastern US. Over 3,000 cypress domes, in a region typical of urban growth in the cypress range, were identified in images from 1984. Over a 20-year period, 26 % were destroyed or degraded (i.e., no longer cypress-dominated) and almost half in managed forests were degraded, destroyed, or became surrounded by urban or agricultural land uses. The smallest and largest cypress domes were lost, leaving only medium-sized wetlands and decreasing landscape-level diversity. Despite the fact that these wetlands are common and partially protected by legislation, cypress in isolated wetlands may be at risk from urbanization.
