Abstract In 2009, in the Special Protection Area Natura 2000 ‘Grądy Odrzańskie’ in Czernica and Siechnice counties, Wrocław district, 95 breeding bird species were recorded. For 33 of them, maps of distribution of their breeding pairs are presented and for the remaining a relative abundance was estimated based on line transect method. In 2009, the following species were recorded in the study area for the first time: Cygnus olor, Crex crex, Upupa epops, and Picus canus. On the other hand, 11 species recorded in 1978-87 as breeding in the study area (Ciconia nigra, Pernis apivorus, Milvus migrans, Milvus milvus, Falco tinnunculus, Gallinago gallinago, Limosa limosa, Tringa totanus, Riparia riparia, Anthus campestris, Phoenicurus phoenicurus) were not recorded again in 2009. It has been shown that Saxicola torquata, Ficedula albicollis, Corvus corax and Remiz pendulinus have increased in numbers. The following species recorded in 2009 as breeding in the the study area: Cygnus olr, Ciconia ciconia, Circus aeruginosus, Crex crex, Alcedo atthis, Dryocopus martius, Picus canus, Dendrocopos medius, Lulula arborea, Sylvia nisoria, Ficedula albicollis, Lanius collurio and Emberiza hortulana are included in Annex 1 of the Bird Directive.

The inventory of birds was conducted in the years 2005-2010 on the Vistula River section between Dęblin (388 km of the river) and Podwierzbie (435 km of the river). The study area includes a southern section of the European Ecological Natura 2000 Site in Poland PLB140004 „Middle Vistula River Valley” (IBA, PL083). In most areas the Vistula flows here within unregulated or relatively little modified riverbed, having features of natural, lowland, braided river. Sandy islands and braid bars within the main channel, steep banks, and old riparian afforestation create the unique breeding habitats of the Vistula River Valley. Especially the river channel habitats provide suitable breeding sites for many rare bird species, constituting some of them the key-breeding sites. There are, however, fragments of several kilometers, where people transformed the Vistula River in a more visible way (Table 1). These are, among others: an urban section within Dęblin boundaries (km 388-393 of the river), a fragment adjacent to Kozienice Power Plant (km 421-426), and the area, where since 2007 gravel for the industry has been mining from the river bottom (km 426-431). The aim of this inventory was the comparison of richness and abundance of breeding bird species associated directly with the river channel on fragments mentioned above. It will allow us to estimate soberly how very the intensity of human utilization of the river affects the distribution of avifauna of the Vistula, determining the richness and abundance of valuable and/or endangered species breeding in a given area.

Abstract In this study the medicinal plants of some representative vegetation types from a human-modified Eastern European landscapes were investigated. The studied territory is part of a Special Protection Area for bird species. The following sampling areas were included in the study: humid grasslands; mountain hay meadows; semi-natural dry grasslands; Sub-pannonic steppic grasslands; fringe communities of mesothermophilic forest edges; grey willow scrubs; thickets of willow; forests of white willow; hornbeam-beech, oak-hornbeam, and sessile oak forests; scrubs of blackthorn and hawthorn; Subcontinental peri-Pannonic scrubs. The ordering of medicinal plants on the basis of presence/absence data and the abundance data presented the grouping in the following typical communities: to the deciduous forests, to the coppices and scrubs, and to the grasslands and meadows. A total of 208 medicinal plants were found from which 37 species are included in the European Pharmacopoeia, and 13 in the Romanian Pharmacopoeia. The existing list of medicinal plants of the Niraj Valley in the scientific literature was completed with 33 taxa. The medicinal plants containing tannins (18.93%) were in higher percentage followed by those with essential oils (10.68%), flavonoids (10.68%), saponins (9.71%), alkaloids (7.77%), mucilages (6.80%), coumarins (5.34%). However rational (sustainable) exploitation of these natural resources is necessary.

Field Edge

Most studies on edge effect are related to the forest-field edge, i.e. to the ecotone. However, there is a lack of studies attempting to investigate the effect of the distance from the forest/field edge on the avian communities in large continuous forests. The purpose of this study was to investigate this issue. The study area comprised a continuous coniferous forest, the so called Niemodlin Forest, situated in Opole Silesia, SW Poland. The line transect method has been employed in this study. In total, 54 breeding bird species were recorded. On particular 0.5 km section, the numbers varied from 34 to 48. Both the number of species and number of breeding pairs only slightly decreased with the distance from the forest/field edge. Overall, the differences between the mean densities of breeding species on 10 sections were not statistically significant. The Chaffinch Fringilla coelebs was by far the most numerous bird species, recorded as eudominant in 164 out of 165 sections. The Chiffchaff Phylloscopus collybita, Willow Warbler Phyloscopus trochilus and Blackap Sylvia atricapilla were dominants in all 10 sections, while the Blackbird Turdus merula dominated in nine (90%) and the Robin Erithacus rubecula in eight (80%) sections. The communal dominance slightly increased, but the number of dominant species and Pielou’s Evenness Index remained stable with the increase of the distance from the forest/field edge. While Shannon’s Diversity Index remained constant, Simpson’s Diversity Index decreased markedly with the increase in distance from the forest/field edge. The proportion of long-distance migrants slightly decreased, while that of short-distance migrants and residents remained constant with the increase in the distance from the forest/field edge. Strikingly, no such changes in the proportion of all feeding guilds were shown. More than half of all breeding bird species show a negative correlation between population density and the distance from the forest/field edge. The dominance of some species decreased with the increase of the distance from the forest/field edge: Hawfinch Coccothraustes coccothraustes, Starling Sturnus vulgaris, Blue Tit Parusa caeruleus, Raven Corvus corax, Wren Troglodytes troglodytes, Wood Pigeon Columba palumbus, and Wood Lark Lullula arborea. With the exception of the Yellowhammer Emberiza citrinella, the clearcuts in this study, not only failed to increase, but most probably caused a decrease in the number of both species and individuals. It is because clearing not only creates edges, but also causes loss of forest habitat and often results in forest fragmentation. Edge and area effect may in fact interact, in such way that the edge effect may drive out the area effect, causing the increase.

Abstract The ecosystems from the Special Protection Area ROSPA0071 „Lower Siret Meadow” (36492 ha, between Adjud city, Vrancea County and Şendreni village, Galaţi County) in the analysed sector (sixteen sample surfaces) present a scientific interest because of the geographical, ecological and biological characteristics. The paper treats details such as the number of individuals, the spatial distribution, availability of suitable habitats and threats, necessary data for the evaluation of the conservation status. We present the data obtained in the period 2010–2014 from 64 field visits in the Special Protection Area ROSPA0071 „Lower Siret Meadow”, all made in the hiemal season. The observations were made as an activity of monitoring the protected bird species distribution and habitat selection of wintering populations. Five important sites were identified as being used by wintering birds here. During the monitoring actions, eighty–one bird species were identified. The paper brings new data about the way birds use their range and existing habitats for wintering.

Abstract Niemodlin countryside (c. 300 km2) is situated in the south-western part of Opole Silesia, SW Poland. Forests occupy c. 40%, arable grounds – 1/3, and meadows and pastures – 7%. There are 31 fish-ponds with a total diked surface of 663 ha. The paper presents results of field investigations carried out during the years 2002-2007 and an analysis of changes in the breeding avifauna over the last 56 years. During the years 2002-2007, 123 breeding and 11 probably breeding bird species were recorded in this area. During the years 1962-2007 151 species were recorded as breeding residents; and additional five species – as probably breeding resident. The following species were recorded as breeding for the first time in 1962-2007: Haliaeetus albicilla, Larus canus, Motacilla cinerea, Saxicola torquata, Locustella luscinioides, Ficedula albicollis, Corvus corax and Carpodacus erythrinus. In the same period the following species became extinct: Podiceps nigricollis, Anas clypeata, Milvus milvus, and Tringa glareola. The following species increaed in numbers in 1962-2007: Coturnix coturnix, Grus grus, Columba oenas, Apus apus, Dryocopus martius, Dendrocopos medius, Motacilla cinerea, Saxicola torquata and Corvus corax. In the same period, Tachybaptus ruficollis, Podiceps cristatus, Podiceps grisegena, Ciconia ciconia, Aythya nyroca, Perdix perdix, Gallinago gallinago, Larus ridibundus, Tyto alba, Alcedo atthis, Picus viridis, Riparia riparia and Corvus cornix decreased in numbers. The areas with the highest concentration of rare and endangered species are postulated to be protected as nature reserves, landscape parks and other spatial forms of nature conservation.

Seven species of birds of prey studied in the Evros Delta National Park belong to a common assemblage of a trophic guild. However, their diet study revealed different groups of feeding niches. A cluster analysis provided three groups with very similar diets: The eastern imperial eagle (Aquila heliaca) and greater spotted eagle (Clanga clanga) constituted a group feeding mainly on birds with their diets including 96% (13 bird species) and 98% (16 bird species), by number respectively, most bird prey being water birds. A second group, characterized by a considerable variety of prey types dominated by small mammals and birds, included the western marsh harrier (Circus aeruginosus) (67% mammals, 27% birds -at least 12 species ), black kite (Milvus migrans) (46% mammals, 39% birds -at least 11 species) and common  buzzard (Buteo buteo) (birds 36% -at least 7 species, mammals 22%). In all three species, birds dominated by biomass, whereas other prey such as arthropods (mainly insects), amphibians and reptiles had a low contribution by mass where they occurred. A third group included the common barn owl (Tyto alba), feeding mainly on small mammals (97%, at least 12 species) and little owl (Athene noctua). The little owl’s diet consisted of mammals (29%, -at least 6 species), birds (5% -at least 7 species) and, though insects preponderated by number (64%), mammals were dominant by biomass in both owls. Diversity indices estimated on class level were low, ranked as B. buteo > M. migrans > A. noctua > C. aeruginosus > A. heliaca = T. alba > A. clanga. Dietary similarities may be partly due to common habitat preferences and the role of other potential factors to niche partitioning is discussed.

Abstract The aim of the study done in 2011 and 2012 was to identify the number of breeding bird species, to provide population estimates as well as to evaluate the conservational importance of Škocjan Caves Park for birds. Common bird species were surveyed using the territory mapping method. Rare species and nocturnally active species were surveyed using species-specific methods: observation, the playback method and the line transect method. 81 species were registered, 49 of which bred within the boundaries of the Park. The most abundant breeding species were Blackcap Sylvia atricapilla (260-320 breeding pairs), Robin Erithacus rubecula (250-310 breeding pairs), Blackbird Turdus merula (230-280 breeding pairs), Chaffinch Fringilla coelebs (230-280 breeding pairs) and Marsh Tit Poecile palustris (200-240 breeding pairs). Qualifying species for the Special Protected Area (SPA) Kras (SI5000023) also bred within the Park: Peregrine Falcon Falco peregrinus, Nightjar Caprimulgus europaeus, Scops Owl Otus scops and Woodlark Lululla arborea. Eagle Owl Bubo bubo was also registered, but breeding attempts during the study period were unsuccessful due to the negative influence of several factors. One of the largest colonies of Alpine Swifts Apus melba, a rare and localized species in Slovenia, is also of conservation concern.

Abstract The Plopul salt marshes, Tulcea County, developed within the perimeter of Lake Beibugeac, have been identified as having a high concentration of halophytes on a relatively small area of about 100 ha. These have formed vegetal communities that fit within two types of Natura 2000 habitats: 1310 Communities of Salicornia and other annuals colonising mud and sand and 1530* Pannonic salt steppes and salt marshes. Four of the 57 species recorded are rare at national level: Halocnemum strobilaceum, Limonium bellidifollium subsp. danubiale, Limonium meyeri and Salicornia prostrata. The area currently has a SPA (Special Protection Area) status, but the unique concentration of halophytes, the presence of Natura 2000 habitats and of rare species, also recommend the area for designation as a SCI (Sites of Community Interest).

A total of 117 bird species has been recorded in Sehlabathebe National Park, south-east Lesotho, consisting of 29 vagrants, 18 visitors and 70 breeding and probable breeding residents. For each species status was determined and abundance roughly estimated. Quantitative studies on breeding bird communities were carried out by means of the line transect method on four transects with the total length ca 30 km in the park and on two transects with the total length of ca 20 km outside the park. In the park, dominant species were represented by the Stonechat Saxicola torquata, Ayres’ Cisticola Cisticola ayresii, Yellow-rumped Widow Euplectes capensis and Wailing Cisticola Cisticola lais. Outside the park dominants were represented by Cape Weaver Ploceus capensis, Cape Sparrow Passer melanurus, Cape Canary Serinus canicollis, Common Quail Coturnix coturnix, Stonechat, Cape Bunting Emberiza capensis and Drakensberg Siskin Pseudochloroptila symonsi. Characteristic, high-altitude species in the park included Drakensberg Siskin, Mountain Pipit Anthus hoeschi, Orange-breasted Rockjumper Chaetops auriantius, Banded Martin Riparia cincta and Sentinel Rock Thrush Monticola explorator. Species such as the Laughing Dove Streptopelia senegalensis, Sicklewinged Chat Cercomela sinuata, Mountain Chat Oenanthe monticola, Thick-billed Lark Galerida magnirostris, Red-winged Starling Onychognathus morio, Alpine Swift Apus melba Cape Sparrow, Grey-headed Sparrow Passer diffusus, Red Bishop Euplectes orix and Golden Bishop Euplectes afer were absent or occurred in very low densities in the park, although they are widespread and common in the Maluti/Drakensberg grasslands (including areas neighbouring to the park). The lack of trees and shrubs for nesting, the lack of cultivated fields as feeding places and competition with related species both for food and nesting sites, may partly play a role in this regard.

AbstractNumerous bird species, often rare or endangered, rely on the presence of standing and downed deadwood for shelter, nesting, and foraging. Habitat quality was evaluated on the basis of deadwood volume, the density of large standing deadwood, and the space filling index (SFI). The SFI reflects the degree of space filling of the bottom layers taking into account tree trunks, seedlings, saplings, ground vegetation, stumps, and downed deadwood. Analysis encompassed all special protection areas (SPAs) in Poland (a total of 107 SPAs containing 7974 sample plots monitored under the National Forest Inventory). An additional in-depth analysis was conducted for 30 SPAs with the greatest share of forest habitats. The studied indicators varied substantially both between and within individual SPAs, with deadwood volume ranging from 1.3 to 50.5 m3 ha−1 (mean of 9.0 m3 ha−1) and the density of large standing deadwood (diameter at breast height ≥ 30 cm) from 0.1 to 16.0 ind ha−1 (mean of 2.2 ind ha−1). These values were relatively low compared to the density of living trees with corresponding dimensions (111 ind ha−1). SFI analysis indicated high or very high space filling of the bottom forest layers on 14–56% of sample plots in a given SPA. The presence of deadwood was found to be significantly positively affected by SPA location in the mountains, a greater proportion of sites with higher fertility, a greater share of forest area under strict protection, as well as higher stand volume within a given SPA. The correlation between deadwood volume and the density of birds (primary and secondary cavity nesters) in individual SPAs was positive (R = 0.60). As compared to lowland areas, SPAs in mountain areas are generally characterized by high stand volumes, a greater density of large living trees, and a greater amount of diverse deadwood. In those areas conservation measures should involve continuous monitoring and diagnosing of any problems associated with the populations of individual bird species; focused efforts should be implemented to support those species that exhibit unfavorable population trends. In most lowland SPAs measures aimed at the improvement of site conditions for birds must be more extensive than in the mountains, with a low abundance of dead trees (especially large ones). These parameters can be improved by retaining some senescent stands in managed forests until their natural death and implementing a strict protection regime in areas of high conservation value.
