I monitor the status of wildlife and research practical solutions to conservation problems. Recent projects include assessing the population trends of British Mammals, researching the hazards posed to bats by wind turbines; working on the negative (and sometimes positive) effects of roads and street-lighting for wildlife; assessing plastic ingestion by wild animals; initiating a sustainable vanilla production project in Ecuador; working on fish-farming and local anti-poaching agreements in Zambia; and developing the MammalMapper phone-app to improve the monitoring of mammals. I am the founding Chair of Mammal Conservation Europe (https://mammals.eu), former Chair of the UK's Mammal Society, Trustee of the Kasanka Trust (UK), and co-founder and Director of Ecotype Genetics Ltd. I also led the Eurobats Scientific Advisory Committee's Working Group on Wind Energy, which had a new resolution adopted by the EU and other member states to monitor and reduce the negative impacts of wind generation on bats. In the UK I have established a MOTUS static radiotracking network for monitoring bat movements, with particular objectives of understanding the threats from offshore wind energy developments and linear infrastructure. My popular science book "Black Ops and Beaver Bombing: Adventures with Britain's Wild Mammals", published in April 2023, was shortlisted for the Wainwright Prize.
