On the basis of the so far collected and/or published data on the White Stork of central Poland (the Łódź Upland) the authors undertook an attempt to explain the spatial and tem poral distribution of breeding efficiency, population density as well as nests localization and nest distribution in relation to human settlements. The efficiency of White Stork breeding depends on biotopic conditions and interspecific competition. Precipitation in spring has a positive while precipitation and low temperatures in June a negative impact on interspecific competition. Habitat conditions of the White Stork have begun to display a constant tendency to decrease in quality, mainly due to land draining. The interspecific competition depends on biotopic conditions and on density. Optimal habitat conditions, including weather ones, may largely neutralize the impact of the intraspecific competition, which enables the population an increase in density, leading even to the appearance of aggregations and colonies. A deterioration in habitat conditions increases interspecific competition, which decreases breeding success to a lower extent than that which could be expected, caused decomposition of aggregations and decrease in the density of breeding pairs. The appearance of a nest outside of the settlement area is a result of interspecific competition.

The eight areas of European or/and domestic importance for birds of Central Poland are presented in this paper. Jeziorsko and Sulejów Reservoirs; valleys of Pilica, Bzura, Ner and Grabia rivers; ponds in Walewice and ponds near Łowicz "Okręt” and "Rydwan” as well as Pilicka Forest and Zaięcze Landscape Park are described in the respect of bird communities and their potential risk assessment. Criteria for identification of other areas of local importance are proposed and 10 subsequent areas fulfilling them are listed.

The authors evaluated the state of the knowledge of the Łódź Upland (about 18 000 km 2) avifauna. The total of 278 bird species was recorded by authors in the study area since the last century. After 1945, the total of 267 species were recorded, including 180 breeding species. According to the authors’ estimates about 11% of the area was investigated more preciously. The best investigated regions are: the Bzura river valley, 219 species were recorded including 165 breeding ones, the Pilica river valley, where the respective values are 211 and 158, region of the Jeziorsko Reservoir - 247 observed species and 152 breeding ones, the vicinities of the locality of Rogów with 118 breeding species and the Łódź city area with 125 breeding species. The Łódź Upland has been the place o f breeding for some rare birds in Poland: Cormorant, Purple Heron, Lesser Spotted Eagle, Hen Harrier, Montague’s Harrier, Curlew, Ruff, Herring Gull, White-winged Tern, Whiskered Tern, Crane, Stonechat, Collared Flycatcher, Aquatic Warbler, Bearded Tit.

The evaluation was conducted using the bird species richness and occurrence of the key species. The key species were: 1. Species endangered globally according to IU CN/BirdLife International criteria, 2. Species of European Conservation Concern (C ategory 1-3), 3. Species from Annex I of Council Directive on the Convention of Wild Birds (79/409/EEC) 4. Species from Polish Red Animal Book, 5. Species which frequency of occurrence in Poland is < 10% according to Atlas of Breeding Birds in Poland data, 6 . Species which number of Polish breeding population is less than 1000 pairs. The key species breed in all kinds of habitats in Łódź. The most valuable habitats are weakly urbanized areas of river valleys and forest habitats with old tree-stands. Among the habitats the most endangered by changes are: river valleys and farmland areas.
