Summary of the impact

York research on the responses of species to habitat fragmentation has led to a paradigm shift in the approach to conservation that has permeated non-governmental organisations (NGOs), governmental agencies and intergovernmental bodies; the traditional concept of protecting and managing populations of species in isolated reserves has largely been replaced by landscape-scale conservation strategies, which increase the long-term survival of species. This new approach is now accepted government policy and has altered practical land designation and management for conservation over millions of hectares in the UK, as well as affecting the strategies adopted by most global conservation organisations and countries in the world.
