ITER-BLOCKS SPACES AND BIRDS PECULIARITIES AND PROBLEMS OF THE ENVIRONMENT PRELIMINARY RESULTS

Dinyo Kyuchukov

University of Forestry Sofia

Abstract:

The papers deals with problems related to the ornitofauna of the large city and particularly the birds inhabiting inter-block spaces (IBS), mostly in the new urban complexes (NUC), and the problems of the environment there. No such studies have been performed so far in Builgaria, even though the problem was partially addressed by some authors.

The number of recorded and nesting species in the IBS is generally not high, but this fact masks the problems consisting not in the total number of the nesting bird species in NUC and IBS, but in the very small number of the nesting pairs in particular IBS in a given year(excluding the species nesting on the buildings). A more serious problem is the very low repeatability of nesting of some species in the same IBS, including species indicatory for the quality of the environment.

The current status of nesting in the IBS is a consequence of the methods applied traditionally for establishment and maintaining the environment there (introduction and maintaining of arboreal plants) and the lacking of adequate approach in this respect.
