05 Mar 2015 “Breeding waders of the Uist machair: Land use and predators, past, present and future”, with John Calladine
The west coast habitats of the Uists hold concentrations of breeding waders that are exceptional in Scottish, British and wider European contexts. Observed declines in wader populations on South Uist and Benbecula since the 1980s were argued to be largely due to predation of clutches by introduced hedgehogs. This argument, supported by evidence from the effects of their experimental removal, led to an ongoing programme of hedgehog removal. Concern remained however that breeding populations of some waders did not show signs of recovery that might be expected in response to hedgehog control. This talk will present some of the findings of recent work investigating associations of changes in breeding wader densities with land uses and new work on the full suite of predators affecting machair waders. Future implications for conservation will be discussed.
John Calladine has had a lifelong interest birds and natural history and has worked in ecological research and conservation for over 30 years. John is currently a Senior Research Ecologist with BTO Scotland, based at Stirling University, with particular interests in the impacts of land uses on bird populations and distribution.
