Abstract
•Annual updates (2008 - 2010) to population trends for individual species (focusing on Biodiversity Action Plan species), and existing UK, England and Scotland biodiversity indicators •Development of novel biodiversity indicators to assess the impacts of climate change, and the first country-level indicators for Wales and Northern Ireland •Interpretation of trends in populations of individual species and butterfly indices in the context of major drivers of environmental change (climate and land use) •The launch of the first stratified random sampling scheme for insect populations in the UK, to establish a baseline for assessing the impact of broad scale environmental factors such as major land use change (effects of wide scale adoption of agri-environment schemes such as ELS) and climate change on butterfly populations
