David Jarrett

David is responsible for managing and carrying out Scottish fieldwork projects, and is also involved with running training courses in Scotland to encourage uptake of BTO volunteer surveys.

BSc (Hons) Economics, Loughborough University (2001-2004).
MSc (Hons) Ecological Economics, University of Edinburgh (2010-2011)

Interests & Responsibilities

David has been involved in a wide range of research and monitoring projects since joining BTO in autumn 2015. Recent and current projects David has been involved in with BTO are:

  • Breeding passerines in the marginal uplands: David is working with John Calladine and Mark Wilson to improve our understanding of how habitat and micro-climate affect breeding birds in marginal upland habitats.
  • Wintering seabirds and marine activity: David has been working with Elizabeth Humphreys on a Marine Scotland funded project investigating sensitivities to marine activity of wintering seabirds, carrying out fieldwork in Orkney.
  • David worked with Stuart Newson, Hazel Evans and Mark Wilson on the Southern Scotland Bat Survey, an ambitious citizen science project funded by SNH, which made significant advances in our understanding of bat populations in the south of Scotland. The results from this survey have recently been published (see below).
  • Wensleydale Waders Pilot Project: David has been working with the Yorkshire Dales National Park Authority and estates in Wensleydale developing trial methods for gamekeepers and farmers to monitor upland breeding waders.
  • The 2015-2016 Non-Estuarine Waterbird Survey in Scotland, a large-scale survey of wintering coastal birds. David carried out fieldwork across many remote parts of Scotland’s coastline, and also co-ordinated volunteer survey effort in various Scottish regions.

Other Information

David has an interest in payments for ecosystem services projects and developments in natural capital accounting, having previously worked in this area and studied Ecological Economics. He has also been involved in pearl mussel conservation in Scotland. David recently spent time in Norway working on the Norwegian Breeding Bird Survey.
