  1. Control predators not on islands for waders

    A replicated, controlled trial at 13 lowland wet grassland sites in England and Wales between 1996 and 2003 (Bolton et al. 2007) found no overall increase in the success of 3,139 northern lapwing Vanellus vanellus nests during four years with predator control, compared to four years without. However, when differences in initial predator densities were accounted for, control did improve survival, having a greater impact at sites with higher predator densities. At two sites where predators were controlled for all eight years, nesting success was not significantly different from the 11 other sites. Predators were red fox Vulpes vulpes and carrion crow Corvus corone, with average declines of 40% for foxes and 56% for crows.
