This paper will analyze the cause of, and ecological and biogeographical consequences of fragmentation process of habitats and ecosystems. Fragmentation process of the autochthonous habitats that without doubt leads also towards the break in their continuity shows by placement in all areas that are under the anthropogenic influence, and as well under the influence of the natural hazards. Spatial and functional isolation as the consequences of fragmentation can be overcome with the help of the formation of the ecological networks and corridors whose dynamic of management will be in accordance with the dynamic of change in habitats formed as the consequence of the fragmentation.
