“…Breeding records included nest locations (Red Kite, Little Owl, Northern Lapwing) or singing males during the breeding period (Skylark, Woodlark, Whinchat, Red-backed Shrike, Corn Bunting and Yellowhammer) and were obtained from four data sources: species survey data from official databases of the federal states, inventories within SPA, the German Common Breeding Bird Survey (GCBBS) and private data of experts working on these species (Table 2). The GCBBS includes four visits per breeding season and takes place on 1300 study plots of 1 km 2 size following a random sampling design stratified according to land-use and ecological regions and covering the entire terrestrial area of Germany (Hoffmann-Kroll et al, 2003). Bird data from 937 of 1300 study plots in Germany (Bibby et al, 2000) were digitized and used for our modelling.…”

Increased energy maize production reduces farmland bird diversity

Producing energy crops as an alternative to fossil fuels in order to reduce CO 2 emissions will lead to large-scale changes in agricultural landscapes. Here, we quantify the potential impact of an increase in maize fields on the diversity of farmland birds by means of high resolution (25 9 25 m) land-use scenarios. We generated scenarios in which the area of maize production in Germany increases from presently 2.6 to 2.9, 3.6 and 4.3 million ha, corresponding to the energy crop production targets of the German Renewable Energy Act for the years 2020, 2035 and 2050. To test the mitigating potential of conservation measures, each scenario was generated in a standard version and a landscape protection version, with the latter excluding valuable farmland areas from being converted into maize fields. Nine species of farmland birds belonging to the governmental indicator scheme for sustainable land-use in Germany were modelled for the six nation-wide scenarios. The models predicted that only the Northern Lapwing and the Little Owl might profit from extended maize production. Despite this, the total number of breeding pairs of the indicator species was predicted to decline by about 0.4 million breeding pairs in the most intensive scenario. Protection of valuable farmland did not mitigate these negative effects in the models. Our findings suggest that increased production of energy crops conflicts with conservation of biological diversity.

“…Assessment of the quality of habitats on a wider landscape scale (not only in legally protected parts, but also in other landscapes) is rather unique. Similar studies are known from Germany [40] and the USA [41]. Other studies only focus on small groups of habitats or on selected habitats, mainly concentrated on plant species diversity.…”

Important sources of information in the field of nature protection are red lists, which define the degree of threat to individual species. In practice, an assessment of the quality of the habitats in which a species occurs is used to a very limited extent in the preparation of red lists of vascular plants. At the same time, this parameter is usually essential to determine their degree of threat. At present, habitat quality data are available for the territory of the Czech Republic; these were obtained during Natura 2000 habitat mapping in the years 2000–2019. In this paper we propose the use of habitat quality data to determine the degree of threat to selected species of vascular plants and to compile a national red list. Nine plant species from three habitat types were selected for this study: meadows and wetland habitats in the alluvium of large rivers (Cardamine matthioli Moretti, Gratiola officinalis L., Teucrium scordium L.), fen habitats (Carex appropinquata Schumach., C. cespitosa L., C. lepidocarpa Tausch) and ecotone shrub habitats (Rosa agrestis Savi, R. micrantha Borrer ex Sm., R. spinosissima L.). For these species, the quality of the habitats in which they occur was analysed and grid maps were created, which present (1) the level of knowledge of habitat quality and (2) the average habitat quality. The results were compared with the degree of threat in the current national red list. Habitat quality analysis should also be used in the future to detect threatened species, which today are outside the red list and this assessment may be useful in compiling another updated red list of vascular plants of the Czech Republic.

“…The GCBBS takes place on 1,300 study plots of 1 km 2 which were selected according to the Ecological Area Sampling scheme (EAS). EAS follows a stratified random sampling design, with the stratification based on land use and ecological regions, across the entire terrestrial area of Germany (Hoffmann-Kroll et al 2003). The GCBBS plots were monitored by highly qualified volunteers in the course of four visits per breeding season (10 March-20 June) using line transect counts of around 3-4-km length inside each recording plot.…”

Abstract& Key message We forecasted the effects of climate change and forest conversion options on common forest bird species by employing nation-wide high-resolution models. The results give details on how, where, and for which species forest conversion can mitigate climate change effects. & Context To mitigate effects of climate change on forests, alterations are required to convert forests into less vulnerable forest types. Coniferous forest that has been cultivated extensively outside its natural range has been identified as being more vulnerable to climate change effects than deciduous forest. & Aims The aim is to evaluate the effect of climate change mitigation measures on biodiversity due to forest conversion. & Methods We generated five forest scenarios for Germany in which we systematically replaced coniferous with deciduous forest types. We forecasted the effects of climate change and forest conversion options on 25 forest bird species by employing high-resolution models to predict their current and future ranges and population size.& Results Our simulations and modeling approach clearly predicted that climate change has a stronger impact on populations compared to distribution areas of common forest bird species. Forest conversion was predicted to amplify (15 species) and to weaken (10 species) the predicted gains and losses of species' population size due to climate change. Using the total bird population size to evaluate the mitigation effect of the different forest scenarios, forest conversion below an elevation of 500 m a.s.l. was predicted to mitigate climate change effects by 0.3 million breeding pairs (−10 %). The relatively weak mitigation effect was mainly due to few generalist species that inhabit coniferous forests in large abundances and did not profit from a conversion to deciduous forests. & Conclusion The results of the study give details on how, where, and for which species forest conversion can mitigate the anticipated effects of climate change.
