“…To date, AES targeted at breeding waders have focused on manipulating the intensity and timing of grazing, mowing or cultivations to reduce the risk of nest destruction by trampling or mechanical operations (Ausden & Hirons , Kleijn & Van Zuijlen , Verhulst et al . , O'Brien & Wilson ). Measures have also included raising of soil water tables, and reducing agrochemical inputs as means to increase prey availability and nesting habitat quality (Ausden & Hirons , Wilson et al .…”

Failure of AES to halt population declines may result from poor implementation of habitat measures, high predation rates or simply the fact that high‐quality agri‐environment measures are not deployed on a sufficiently large scale to reverse national population declines (O'Brien & Wilson , Smart et al . ).…”

Habitat associations of farmland birds are well studied, yet few have considered relationships between species distribution and soil properties. Charadriiform waders (shorebirds) depend upon penetrable soils, rich in invertebrate prey. Many species, such as the Northern Lapwing Vanellus vanellus, have undergone severe declines across Europe, despite being targeted by agri‐environment measures. This study assessed whether there were additive effects of soil variables (depth, pH and organic matter content) in explaining Lapwing distribution, after controlling for known habitat relationships, at 89 farmland sites across Scotland. The addition of these soil variables and their association with elevation improved model fit by 55%, in comparison with models containing only previously established habitat relationships. Lapwing density was greatest at sites at higher elevation, but only those with less peaty and less acidic soil. Lapwing distribution is being constrained between intensively managed lowland farmland with favourable soil conditions and upland sites where lower management intensity favours Lapwings but edaphic conditions limit their distribution. Trials of soil amendments such as liming are needed on higher elevation grassland sites to test whether they could contribute to conservation management for breeding Lapwings and other species of conservation concern that depend upon soil‐dwelling invertebrates in grassland soils, such as Eurasian Curlew Numenius arquata, Common Starling Sturnus vulgaris and Ring Ouzel Turdus torquatus. Results from such trials could support improvement and targeting of agri‐environment schemes and other conservation measures in upland grassland systems.

Summary1. Within Europe, agri-environment schemes are the key delivery mechanism for biodiversity conservation outside protected areas. Schemes have a range of land management options designed to deliver outcomes for target habitats or species. 2. Breeding waders form an important part of the biodiversity of upland grasslands, and in the UK, there are multiple land management options within agri-environment schemes designed to benefit waders. We assessed whether such options improve the suitability of breeding habitat and population dynamics for a declining wader, the lapwing Vanellus vanellus. 3. The suitability of nesting and chick-rearing habitat was better on land with agri-environment scheme management, and breeding densities and productivity increased with habitat suitability. 4. The lapwing populations declined during this study, and trends did not differ between agri-environment and non-agri-environment scheme land. Productivity was below that required for population stability, although there was evidence of higher productivity on agrienvironment scheme land in later years. 5. Agri-environment management consisted of multiple land management options that varied in delivery of suitable habitat, breeding densities and success. The best management options were all in England on land benefiting from specific management advice or with rough grazing and grazed pasture agri-environment scheme options. 6. Synthesis and applications. Despite considerable investment and positive effects of agrienvironment schemes on habitat quality, populations of lapwing in the UK uplands have declined because of inadequate productivity. For species with complex requirements, populations are only likely to increase when all of these requirements are provided. Appropriately targeted habitat management, delivered through agri-environment schemes, can play an important role in improving habitat quality and increasing landscape diversity. However, when populations are limited by something other than habitat quality, for example, predation, then habitat management alone is unlikely to recover populations. Increasing evidence suggests that predation impacts are also likely to be important for ground-nesting species such as lapwing. Predator management may therefore need to be integrated with habitat measures where predation is limiting breeding success and population recovery.

“…Frequently they provide benefits to wild species (Davey et al 2010b), but often the design of such schemes has not been based on their potential effects on biodiversity, which may result in only partial benefits, or even negative effects on many species (Kleijn & Sutherland 2003, Birrer et al 2007, Davey et al 2010a, including some of conservation concern (Kleijn et al 2006). Agri-environmental schemes may not be sufficiently tuned to the ecological requirements of species (Kleijn et al 2004), and often fail to enhance population trends (O'Brien & Wilson 2011, Princé et al 2012. Reasons for lack of effects include a focus on small spatial scales, a lack of coordination among farmers at the landscape scale and restricted temporal scales (Siriwardena 2010).…”
