During her first year with Windrush Ecology, Claire has gained experience in Ecological Impact Assessments, Biodiversity Net Gain, and protected species surveys, with a particular focus on bats. Her background lies in large African mammals, having completed research into African forest elephant behaviour in the forests of the Congo basin utilising camera trapping technology. She is now branching out into somewhat smaller mammals and developing her botanical surveying skills. In her free time, Claire enjoys long walks in the countryside and working on a range of DIY projects.
