New research from the University of Aberdeen and Edinburgh Napier University suggests that adjusting the timing of conservation measures on farmland could significantly improve protection for some of the U.K.'s most rapidly declining wading birds, such as lapwings, oystercatchers, and curlews. Between 1995 and 2024, populations of these birds in Scotland fell by 63% for lapwings, 41% for oystercatchers, and 62% for curlews. One major reason for this decline is changes in how agricultural grasslands are managed, including earlier and more frequent mowing and high livestock densities, which make it harder for ground-nesting birds to breed successfully. In the U.K., agri-environment schemes offer financial incentives to farmers to protect wildlife by delaying certain farming activities, such as mowing or grazing, until later in the breeding season. However, these schemes typically use the same dates across the entire country, regardless of local conditions. A new study published in the Journal of Applied Ecology found that this "one-size-fits-all" approach often doesn't align with the actual breeding periods of the birds. Using nesting data from across the U.K., including information from the British Trust for Ornithology and the Royal Society for the Protection of Birds, researchers discovered that breeding seasons vary significantly between species and regions. As a result, even when conservation measures are in place, they are often applied at the wrong time, leaving nests and chicks vulnerable. The research team developed new recommendations that adjust conservation measures based on both the species of bird and the location. Their analysis showed that relatively small changes to current exclusion dates—sometimes as little as two to three weeks—could greatly improve protection. For example, adjusting dates could increase nest protection from livestock by 30% for lapwings and 57% for oystercatchers. Protection for chicks from mowing operations could rise by 35% for lapwings and 72% for oystercatchers. Leah Gray, a postgraduate researcher who led the study, noted that the main reason for the decline in wader populations is a decrease in breeding success. Over the past decades, these birds have not been able to produce enough young to sustain their populations. The study highlights that while many challenges affect breeding success—such as habitat loss, predation, and nest destruction—some issues, like agricultural practices, are easier to address. Modifying livestock management and mowing schedules offers a straightforward way to support wading birds. The research also emphasizes that conservation measures must align with the actual timing of nesting and chick-rearing, as current exclusion dates often miss these critical periods. The study's findings aim to provide practical guidance for NatureScot, which advises the Scottish Government on agri-environment schemes. The researchers hope these insights will help improve the effectiveness of current schemes by ensuring they better match the actual breeding seasons of the birds. The long-term success of these schemes depends on balancing wildlife protection with the needs of farmers. Policymakers must work closely with both farmers and ecologists to ensure changes are both scientifically supported and practical. If implemented, these adjustments could significantly improve breeding success and help protect declining wader populations across Scotland and beyond. Gray added that similar evidence-based approaches could also improve conservation efforts for other species in different regions, offering a cost-effective way to support the recovery of some of the countryside's most iconic birds.
