BTO - Key Persons


Adham Ashton-Butt

Job Titles:
  • Member of the Data Science and Bioacoustics Team
  • Senior Research Ecologist
An experienced field biologist and analyst in the Framing Futures team, Adham takes a broad multi-taxa approach to understand how best to modify or restore landscapes for the conservation of biodiversity, adaptation to environmental change (e.g. climate change), the ecosystem services provided and the trade-offs between these. Adham is an expert at the use of passive acoustic monitoring to monitor a diverse range of often cryptic taxa. Interests & Responsibilities Recent projects have included leading the research and monitoring underpinning a large-scale 5-year landscape restoration project in the Polesia region of Belarus and Ukraine, a collaborative project under the umbrella of the Endangered Landscapes and Seascapes Programme. Adham has advised and been involved with other ELSP projects in Scotland, Romania and Portugal and, with Máire Kirkland, developed models looking at the role of climate and edaphic factors (e.g. soil moisture) on the size and intensity of wildfires in Portugal and Polesia.
