Research Interests

I study the effects of human activities on populations of wild species.  This includes effects on population size and demographic rates of agriculture, game management, habitat change, climate change, pollution and deliberate and accidental killing.  I use statistical and simulation models fitted to data on these effects to devise practical interventions that land managers can use to reduce negative effects on wild species so as to improve their conservation status.  For more than thirty years, a large part of my research work for the RSPB was focussed on how farming methods could be adapted to allow wild species living on farmland to do better and be more likely to have high populations alongside food production.  Often doing this involves the farms producing a bit less food than they would do otherwise. More recently, I have realised that it might also be important to produce the food and the other agricultural products that people require on as little land as possible, and to use as much of the spared land as possible for large blocks of the natural habitats that many wild species need. This conflict, between modifying farming methods so as to share farmland with wild species, but by doing so potentially placing species that need large tracts of natural habitats at greater risk, is a real personal dilemma for me.  With Andrew Balmford and Ben Phalan, I have set up a research programme to collect hard evidence about whether the dilemma really exists and, if it does, how it can be resolved. I am closely involved in the Cambridge Conservation Initiative; and with Andrew Balmford, Rosie Trevelyan and Shireen Green run the annual Student Conference on Conservation Science.
