“…more concealed prey) and the perch height (or even the lack of perches in modern grasslands) are of critical importance for access to prey and hunting efficiency (Andersson 1981;Andersson et al 2009). This concurs with the assumption that the mobility of ground-foraging insectivorous passerines and access to food are of greater importance during the selection of a foraging site than the abundance of food per se, which translates into preferential foraging in short vegetation, even though more invertebrate prey were available in tall vegetation (discussed in van Oosten et al 2014;Schaub et al 2010). Therefore, it is possible that the recent successful colonization of abandoned farmland by the Whinchat and its population increase in this new habitat are in part simply the consequence of favourable foraging conditions and the excellent accessibility of prey in the loose vegetation or bare ground present there.…”

“…in the Scottish Highlands Whinchats preferred warmer south-facing hillsides (Calladine and Bray 2012)]. One can assume that the major threats to Whinchats and other birds breeding in grasslands nowadays are the direct mortality/ nest losses of birds due to mowing and the intensification of agricultural management as a result of the encroachment of tall grass species resulting from nitrogen deposition and acidification, which diminish habitat suitability and reduce prey accessibility Broyer et al 2014;Fischer et al 2013;van Oosten et al 2014).…”

“…Nitrogen deposition enhances mineralization and biomass accumulation in dune, heathland and semi-natural grassland communities. Nitrophilous grasses and shrubs have replaced the original low vegetation, limiting reproduction and foraging possibilities for specialists of early successional habitats, among which are butterflies (WallisDeVries and Van Swaay, 2006) and birds (Van Oosten et al, 2014). The expansion of woodland area (CBS et al, 2014) and the maturation of existing forest stands may have contributed to stabilise the woodland LPI.…”

a b s t r a c tWe calculated a Living Planet Index (LPI) for the Netherlands, based on 361 animal species from seven taxonomic groups occurring in terrestrial and freshwater habitats. Our assessment is basically similar to the global LPI, but the latter includes vertebrate species and trends in population abundance only. To achieve inferences on trends in biodiversity more generally, we added two insect groups (butterflies and dragonflies) and added occupancy trends for species for which we had no abundance trends available. According to the LPI, the state of biodiversity has slightly increased from 1990 to 2014. However, large differences exist between habitat types. We found a considerable increase in freshwater animal populations, probably because of improvement of chemical water quality and rehabilitation of marshland habitats. We found no trend in the LPI for woodland populations. In contrast, populations in farmland and open semi-natural habitats (coastal dunes, heathland and semi-natural grassland) declined, which we attribute to intensive agricultural practices and nitrogen deposition, respectively. The LPI shows that, even in a densely populated western European country, ongoing loss of animal biodiversity is not inevitable and may even be reversed if adequate measures are taken. Our approach enabled us to produce summary statistics beyond the level of species groups to monitor the state of biodiversity in a clear and consistent way.

Continuous animal populations often become fragmented due to anthropogenic habitat alterations. These small, fragmented populations are fragile due to demographic and genetic factors, whereas immigration can enhance their long‐term viability. Previously, we showed that high philopatry affected the local dynamics of three small and remnant subpopulations of Northern Wheatears in The Netherlands. Here, we show that these three populations together with an additional larger population in the European lowlands are highly genetically differentiated based on 22 microsatellite markers. In contrast, we found no evidence for differentiation using two mitochondrial DNA markers. An IMa2 analysis indicates that gene flow has occurred regularly among our sampled populations. As immigration of colour‐ringed birds among our sampled populations is rare at best, our results suggest that the populations have recently become isolated from one another. Low dispersal rates in highly mobile birds may occur when suitable habitat becomes highly fragmented, and will accentuate stochastic demographic processes and inbreeding, both reducing population viability. As dispersal rates are low among populations of Northern Wheatears in The Netherlands, there is only a small probability of recolonization of habitat patches where populations have become locally extinct.
