Abstrakt		In Slovenia, particulary in its northeastern part, only a few wetlands have been preserved. The rarest among them are wet meadows, particulary those subjected to extensive agricultural use, which are of particulary great ecological value. One of such remains is some 155 large Medvedce impounding reservior on Dravsko polje. The reservoir, which was built to impound high waters running from Mt. Pohorje, encloses the last remains of once widely spread wet meadows with separate belts of trees and shrubbery called chreta. In 1993, before the waters rose, a mapping (as per Bibby, Burgess, Hill 1992) was carried out in its birds' refuge. Apart from rich flora and fauna, 32 breeding bird species were ascertained. The most interesting breeder was the Meadow Pipit Anthus pratensis, for its established nest site is probably the southernmost in Europe and the only one in our country. Four pairs bred there, all in wet meadows with predominating sedge Carex sp. and rush Juncus sp. Other breeders, which are more and more endangered and already disappearing in this country, are also very interesting indeed. No less than 13 species, i.e. 40.6% of all established breeders, appear on the Slovene Red List of endangered breeding species. The List of species threatened in Europe (SPEC category 3) includes three species breeding in this area (Turtle Dove, Stonechat and Red-backed Shrike). in 1990, a Snipe Gallinago gallinago was also known to breed here, which is in this country an extremently rare and merely local breeder. In the following years no breeding by this bird was recorded, presumably due to too dry ground. Special attention should be also given to the species from the national Red List, in which high breeding density was ascertained. These are Grasshopper Warbler Locustella naevia (1.3 pair/10 ha), Sedge Warbler Acrocephalus schoenobaenus (2.3 pairs/10 ha), and Red-backed Shrike Lanius collurio (0.7 pair/10 ha) (Table 1).(Abstract truncated at 2000 characters.)
