They are perceived as the areas dominated by the elements of technical infrastructure. But new ideas, especially sustainable development, allow to look on a city as a specific system, in which the important role is played by the environment, both protected and consciously developed and spontaneously driven by natural succession. All it means that the ecological role of urban infrastructure is being considered more often. A good example is Poznań Fast Tramway Route, which through its specific location and construction has very high biological potential. Using mainly a method of field interpretation of aerial photographs (recognition, evaluation and classification of objects in photographs with visual observation of these objects on the ground) several categories of green areas, both spontaneous and cultivated were distinguished. The collected data are promising with regard to more aware development of similar linear elements of infrastructure (e.g., railroads, roads, highways etc.), which, along with its main transport function, are a vital element of the city's environmental system (as animal habitats, ecological corridors etc., but also as green zones with positive influence on the aesthetics of the surrounding areas).polinfo:eu-repo/semantics/openAccessArtykuł
