Abstract: Urbanization in the Concepción metropolitan area (36 S) has historically impacted valuable ecological areas such as wetlands and lagoons. We built indicators to analyze disturbance of biodiversity in six urban wetlands. We propose three measures: a Naturalness indicator and two indicators for Plants and Macrolepidoptera species richness. Multiple regression models were developed for the assessment of indicators. Results show that the wetlands with the lowest degree of human interference are located in a protected area and surrounded by a matrix of semi-natural landscape, whereas the more disturbed ones are closer to urbanization. Results indicate that Macrolepidoptera richness is more affected by the distance to roads, in contrast with the richness of plants, which is affected by housing density. A tool for the prevention of loss of species and the conservation of these ecosystems in urbanized areas is generated.
