Since childhood I have been obsessed with the natural world. Growing up in Cornwall in the UK I was close to nature and I found endless pleasure in collecting bugs, beetles and worms before graduating to more exotic amphibians and reptiles. Before long I had acquired a fascination with toxic creatures and I could not, at this early age, understand why so many people were so fearful of such things. As my curiosity about the natural world grew so did my interest in what could be done to counteract the conflict and fear between humans and wildlife and the frequently unwelcome results. I wanted to be able to offer solutions to this divide between humans and wildlife. Driven by my fascination and deep respect of snakes I undertook a PhD looking at reducing the huge issue of snakebites in India. Now, I have moved to Kenya to work on the ever-increasing issue of human-elephant conflict.


harry with reptile on armGiven my early confusion at humanities general lack of tolerance for nature it feels rather fitting that a large proportion of my adult life has been spent researching human-wildlife conflict. This research has been primarily in the form of snakebite research, looking at both behavioural and pharmacological interventions for reducing this issue as well as more recently recommencing research into human-elephant conflict. As the two non-human vertebrates causing by far the most deaths in Kenya (where I am based) it feels fitting to concentrate on animals so deserving of the associated fear. After spending most of my time concentrating on the animal side of these issues I am ever more finding that the real solutions have to come from the human side and my current research is primarily focused on large scale interventions to initiate behaviour change in affected communities.

harry with reptileI am currently working as a post-doc for Save the Elephants where I am leading an impact assessment of a country-wide programme taking a mobile cinema around Kenya’s most elephant-conflicted regions and showing these communities The Elephant Queen film. This is a cinematic documentary  

This study is aiming to understand how viewing a nature documentary can begin to shift attitudes towards a more positive relationship with elephants as well as gaining an understanding of the regions struggling most with Human-Elephant conflict and designing a strategy for helping to ameliorate this conflict long-term. This research will take me and my team of four others around the Tsavo, Amboseli and Samburu regions of Kenya to undertake questionnaires and interviews with those watching The Elephant Queen. In all we will visit 75 or more locations and the aim is for The Elephant Queen to be shown to 200,000 people or more.
