The aim of this paper is to explore the direction and rate of change in land use of the biancana badland landscapes over the last 50 years, evaluating the erosion-vegetation dynamics and examining the processes involved in 2 biancana badlands, "Lucciola Bella" in Tuscany and "Crete di Camposodo & Crete di Leonina" near Siena. First, the AA. analysed the landscape changes that occurred in the biancana areas from 1954 to 2005, comparing old and recent land use maps. TWINSPAN classification was applied on selected plots of a plant dataset to distinguish vegetation types and identify the indicator species of each different type. They then evaluated soil erodibility on the eroded biancana surfaces, regosols and well-developed vertisols. The AA. aim to find possible solutions and ways forward to render the preservation of the biancana landscape and its biodiversity more efficient
