Methodology for Identifying Ecological Corridors: A Spatial Planning Perspective
Oana-Cătălina Popescu; Antonio-Valentin Tache; Alexandru-Ionuț Petrișor
Recent studies carried out by landscape and urban ecologists have shown that habitat fragmentation has negative environmental effects and is accountable for the loss of biodiversity. The development and extension of road infrastructure to support economic growth, the urbanization and the land-use changes are major drivers of habitat fragmentation. Planners have attempted to develop tools for restoring connectivity and stopping biodiversity loss at the landscape scale and which can be applied at the urban scale, too. The study fills in the gap by developing a methodology for identifying the ecological corridors of a Romanian large carnivore (brown bear) in the Romanian Carpathian Mountains at several spatial scales. The methodology relies on geospatial data: this is equally its most important advantage and challenge. Our findings suggest that the implementation of ecological corridors in current planning practice must be completed cautiously, provided the possible restrictions are imposed on economic activities by plans, and highlight the importance of field data in increasing the scientific soundness of the results. In addition, the findings show the need to interconnect spatial planning policies with environmental policies by improving the actual legislation.
