De Snoo, AuteurAgricultural intensification in grasslands has led to the decline of meadow bird populations in The Netherlands in the last 60 years. Habitat for meadow bird chicks has declined in quality and quantity, thereby reducing food availability. Agri-e[...]

De Snoo, AuteurTo help restore food availability for birds, arable field margins (extensively managed strips of land sown with grasses and forbs) have been established on European farmland. In this study we describe the effect of field margins on the diet of E[...]

Ernst B. Oosterveld, Auteur ; Freek Nijland, Auteur ; Cees J. M. Musters, Auteur ; Geert R. De Snoo, AuteurSince 2000, a new management technique has been introduced to stop the rapid decline of grassland breeding shorebirds in the Netherlands, called 'mosaic management'. The most important difference from earlier Agri-Environment Schemes is that the[...]
Article
Steven Kragten, Auteur ; Geert R. De Snoo, AuteurIncreasing agricultural intensification has put farmland bird populations under great stress. Although organically managed farms tend to have higher densities of farmland birds than conventionally managed holdings, differences in crop management[...]
Article
Suzanne K. Lubbe, Auteur ; Geert R. De Snoo, AuteurCapsule Dairy farm management methods have no influence on numbers of Swallow breeding pairs. Aim To identify differences in Swallow abundance between organically and conventionally managed dairy farms, by examining three factors: farm buildings[...]

Joke Maes, Auteur ; C. J. M. Musters, Auteur ; Geert R. De Snoo, AuteurThe Western Peat District of The Netherlands has a characteristic Dutch landscape. It consists mainly of meadows for dairy farming, crisscrossed by a dense network of ditches. Its biodiversity is regarded as of high national and international im[...]
Article
William F. A. van Dijk, Auteur ; Jasper van Ruijven, Auteur ; Frank Berendse, Auteur ; Geert R. De Snoo, AuteurThe effectiveness of agri-environment schemes (AES) in enhancing biodiversity in agricultural landscapes is still strongly debated. In the Netherlands, one of the most widely implemented AES is the management of ditch banks to enhance plant spec[...]
Article
Steven Kragten, Auteur ; Jan C. Nagel, Auteur ; Geert R. De Snoo, AuteurClutches of ground-nesting farmland birds are often destroyed by farming operations, resulting in insufficient reproductive success and subsequently declining populations. The aim of this study was to investigate whether volunteer nest protectio[...]

(2010, Ibis 152: 368-377) suggested that intronic variation in the CHD1-Z gene of Black-tailed Godwits breeding in southwest Friesland, The Netherlands, correlated with fitness components. Here we re-examine this surpri[...]
