Wader Study | Year: 2016

We monitored the abundance of eight breeding wader species in the Vinogradovo Floodplain during 2002–2014 and compare our results with data from 1982– 1983 and 1995–1996. We describe the trends in agricultural land use in the region, as well as trends in the intensity of spring flooding, and relate these to fluctuations in the abundance of waders. The level and duration of spring floods is an important natural factor which can interact with changing land use and farming practices. We suggest that a strong reduction in the intensity of farming activities (up to full termination of grazing and ploughing) and a decrease in the intensity of floods at the end of the 20th century are the main factors influencing the abundance of waders. As a result of these changes, we observed catastrophic declines in the numbers of Ruff Philomachus pugnax and Terek Sandpipers Xenus cinereus, and strong declines in the abundance of Northern Lapwings Vanellus vanellus and Black-tailed Godwits Limosa limosa. We observed variable numbers of Great Snipes Gallinago media and Marsh Sandpipers Tringa stagnatilis during 2002–2014, but no strong trends, and observed a slight increase in the abundance of Common Snipes G. gallinago. We discuss the reasons for changes in numbers of each species, in relation to environmental and land use change. © 2016, International Wader Study Group. All rights reserved.

Since the negative trends in bird populations breeding in intensified farming systems of western Europe could be difficult to reverse, this article highlights the importance of also considering conservation measures in key-sites for grassland birds in European Russia where farming abandonment is the prevailing threat. Non-passerine bird species frequency was studied in the period 2007–2009, within 193 count points in diversely managed meadows of 36 key-regions in Russia and compared to the outcomes of 492 count points in hay meadows of 25 key-regions in France. In Russia, five species were recorded in at least 35% of the plots, among which the Corncrake Crex crex in 75% of total sample. Pair density was defined in two hay meadow systems in Russia with the Territory Mapping method. Bird biomass density was not different when compared to the most favourable conditions recorded in France, but with a Corncrake density of 2.1 calling males per 10 ha vs.1.0 in the major French stronghold. Experimental results of alternative management showed the limits of mowing postponement programmes in French grassland ecosystems and enabled us to explore the effects of rotational mowing for limiting habitat loss due to farming abandonment in Russia. © 2016 Elsevier GmbH

Bird Study | Year: 2014

Capsule: Improving habitat quality through late or intermittent mowing may increase passerine population density without reducing reproductive success. Aim: To describe the relationship between passerine territory density (TD) and Whinchat Saxicola rubetra and Yellow Wagtail Motacilla flava hatching success, under different management regimes. Methods: TD was defined by the Territory Mapping method in nine sites selected in five French flood plains, in four intermittently mown meadows in Russia and in four additional French sites where mowing was partially postponed. Hatching success was assessed by the observation of prey carrying. Generalized Linear Mixed Models were used to analyse the influence on hatching rates of mowing management, early mowing and TD. Linear Mixed Models were used to study the effect of mowing management on TD. Results: In French early mown meadows, TD affected reproductive success. Higher hatching rates and TD were observed in Russia. Similar results in French study sites with postponed mowing confirmed the influence of mowing management on carrying capacity. Conclusion: In west-European grassland systems, late or intermittently mown patches within or at the edge of meadow areas, with potentially improved invertebrate-prey availability, should help to sustain bird demography and improve the efficiency of current conservation programmes. © 2014 British Trust for Ornithology.

Two decades of agri-environmental policy did not prevent a long term decline of grassland birds in Europe. Additional measures are therefore needed to sustain the populations. This study explored alternative mowing management regimes likely to secure demographic sources in the early mown grassland systems of western Europe, and to limit habitat loss after farming abandonment in countries of the former Eastern Bloc. Postponing grass cutting until after mid-July from 2009 to 2014 in half of the area of 4 study sites (29-55. ha each) in the Saône Valley (France), led to increased territory density and improved hatching success. Bird response however was species-specific: Corn Bunting Emberiza calandra territory density benefited the most from the alternative management, Yellow Wagtail Motacilla flava territory distribution tended to match the late mown areas, whereas the Whinchat Saxicola rubetra did not change its initial distribution. Temporary interruption of mowing in 8 meadow units (11.7-15.1. ha) of the Moskva Valley (Central Russia) was similarly correlated with higher territory density. Whinchat territory density decreased after one single year of mowing. After two consecutive years of mowing, Whinchat hatching success was lower and the Lesser Citrine Wagtail Motacilla citreola werae virtually disappeared. The tested alternative mowing regimes may therefore locally increase population density without negative density dependent effects on hatching rates. Implementing rotational mowing could reduce habitat loss caused by farming abandonment in Russia. Postponing mowing until after mid-July in patches of hay fields may sustain meadow bird demography in the remaining strongholds of western Europe. © 2015 Elsevier B.V.
