MANAGEMENT PLANS AND WEB-GIS SOFTWARE APPLICATIONS AS ACTIVE AND DYNAMIC TOOLS TO CONSERVE AND VALORIZE HISTORIC PUBLIC GARDENS

Historic gardens are artefacts that evolve in a continuous and unavoidable way, and, at the same time, they are heritage and cultural sites that need to be conserved: the recognition of this dual nature motivates us to seek for new approaches to their management issues. Whilst it is necessary to follow site mutations and valorize its features while dynamically changes the appearance of the garden and the needs of the society, at the same time it is fundamental that an appropriate strategic plan sets a target for the garden, a mid-long term vision, in order to preserve botanic and documentary value and maintain historic and artistic significance. The paper analyzes historical sources, surveys, thematic maps and interpretations to study historic public gardens, considering complexity and vulnerability of the components and issues involved in historic gardens and consequent multidisciplinary approach. In order to identify conservation and management criteria it underlines analysis and evaluation of the environmental, architectural, landscape and perceptive features of the historic garden and its surroundings, demonstrating the importance to study the site historic stratification and the site context in order to define preservation goals to prevent decay, to mitigate impacts, to set up maintenance programs and management plans. The aim of this essay is also to highlight the role of GIS and WebGIS applications -targeted at public administrations -that integrate the spatial component (topographic map, ortophoto, physical plans, cadastral maps) and databases about botanic inventories and conservation and valorization treatments of historic public of public gardens
