The following groups of sites were reported in the observed area: D - mire, bog and fen sites; E- grassland and tall forb sites; F - heathland, scrub and tundra sites; G - forests and forests sites and other reforestated areas; H – inland unvegetated or sparcely vegetated sites; I- regularly or recently cultivated agriculture, horticultural and domestic sites; J - constructed, industrial and other artificial sites. The migration trends over the oberved period also caused the different degrees of endangerment of the natural sites in this area, for the benefit of the sites formed by the anthropogenic influences. Mire, bog and fen sites, as well as grassland and tall forb sites are particularly endangered.The scrub and forest sites are degraded to a great extent. application/pdf 506673 bytes Beograd: Institut za šumarstvo eng
