The most dominant land-uses are fish ponds, marshes, forests, heathland, grassland, residential areas and industry. An ESS approach was adopted as a guiding framework to develop a vision for several reasons: it was felt that ESS stimulate positive thinking, it was expected to stimulate multi-sectoral thinking, and it was considered as a suitable vehicle to achieve resilient and multi-functional landscapes.
