In the last period, serious changes in utilization of the area of Bratislava not only in the sphere of the changed landscape use but also in the development of protected areas and application of the ecological network (EN) have occurred. The agriculturally used plots (arable land, vineyards and orchards) are the most attacked areas at present. Up to 15th March, 2005 there were 2 protected landscape areas, 1 national nature reserve, 1 national nature monument, 8 nature reserves, 3 nature monuments and 15 protected areas. As the aims of protection were not fulfilled, 10 protected ranges were abolished since 1994, the borders of the Protected Landscape Area Malé Karpaty and its protection zone were modified. Within the frame of the European system of protected areas NATURA 2000 were proposed 4 sites of protected bird areas and 10 sites of European importance. Measures proposed in the Regional EN in 1994 have not been realized. Interlinking of biocorridors, their maintenance and revitalization was neglected. Many elements of EN lost their functions but not their groundwork. For the positive development of Bratislava it is necessary to limit the loss of arable land and land of vineyards for building; loss of forest soil and logging for the purpose of "recreation in nature" and to limit the dense construction which causes the diminishing of lawns and playgrounds, cut of urban vegetation as well as the disturbance of the town silhouette.
