New census of breeding in an old beech plantation quadrat in the forest of Soignes (Brabant).
Couvreur, J.-M. & Jacob, J.-P.
In 1995, a census was made in a 27,5 ha quadrat settled in the full-grown beech forest of Soignes, in the near suburbs of Brussels. This quadrat was previously studied in 1970, 1976 and 1987. Results are summarized in Table 1. The evolution of the birds population shows an arrival of some common species resulting from the opening of forested environment (by storms and subsequent cuttings), but also a decreasing and even disappearance of other birds like Tree-pipit, Redstart and Starling. Birds population is nor diversified (15-20 breeding species per year) nor dense (33,5 - 48,25 territories / 10 ha). Factors of that evolution are discussed. Globally, the avifauna of the forest of Soignes becomes ordinary.
