Understanding the combined biodiversity benefits of the component features of hedges

摘要: 1. Hedges are a fundamental component of the UK landscape, making a critical contribution to landscape-scale conservation measures, as recognised in the Lawton report: Making space for nature: a review of England’s wildlife sites and ecological network.2. This report increases our understanding of the role hedges play in supporting biodiversity. It presents information on the importance of managing all hedge components optimally for biodiversity and the inter-relationship of the five structural components of hedges (trees, shrubs, hedge base, field margin and ditches). The focus is on priority species listed in Section 41/42 of the Natural Environment and Rural Communities Act (2006) and equivalent legislation in other UK countries (ie former BAP species), together with species listed as Biodiversity 2020 Farmland Indicators. A total of 107 such species were identified (excluding widespread moths).
