Abstract

Zone Umide della Capitanata, located in the northeastern part of the Apulia Region, is one of the most extensive coastal wetlands of the Italian peninsula and one of the largest components of the Mediterranean wetland system. Despite its high ecological importance, this site has been undergoing a variety of pressures intensified in recent decades. This study analyzes and evaluates the changes occurred in this area between 2010 and 2020. Land cover and habitat maps were performed by photointerpretation and on-site surveys, and classified according to the FAO-LCCS and EUNIS taxonomies, respectively. To focus on local dynamics, four subset areas were analyzed separately. A set of landscape metrics was computed to analyze the landscape structure. The anthropogenic pressures affecting the study area were described through the Driving Forces-Pressures-State-Impact-Response (DPSIR) conceptual framework. Numerous changes were identified, deriving from both finest thematic redefinition and anthropogenic pressures. Both class conversions and class modifications were identified and quantified by means of transition matrices. Most of the observed conversions were borne by classes belonging to saltmarshes and to coastal dune systems. In particular, landscape configuration of coastal dune classes was well highlighted by a set of specific landscape metrics. Agriculture practices and changes in water flow pattern turned out to be the main driving forces exerting pressures on these natural systems. Significant differences were found between the four subsets under analysis, thus indicating that different management strategies lead to different levels of conservation.
