al How to model trade-offs between agricultural yield and biodiversity By ec.europa.eu Published On :: Tues, 27 June 2017 9:23:19 GMT New research has examined three different categories of Ecological Risk Assessment (ERA), each with different goals. The researchers find that overlaps between the three assessments could be combined to create a more comprehensive form of ERA, usable by regulators and environmental decision makers. There is an inherent trade-off between increasing agricultural production and protection of biodiversity. This study models the effects of biodiversity conservation agri-environment schemes (AESs) and ecosystem service provider schemes, and shows that determining the aim of an agri-environment scheme is key to improving its efficiency. Such an optimisation could allow AES to be rolled out more generally to provide the backbone for both high yields and enhanced farmland biodiversity, say the researchers. Full Article
al Wildflower planting supports a range of beneficial insects, not only bees By ec.europa.eu Published On :: Tues, 27 June 2017 9:23:19 GMT A study of wildflower planting within agri-environment schemes has demonstrated that the practice can support a diverse array of economically beneficial insect species, not just prominent pollinators such as wild bees and hoverflies.

al How big a threat do invasive alien species pose to European biodiversity? A ranking of species for urgent risk assessment By ec.europa.eu Published On :: Thur, 27 September 2018 9:23:19 GMT Invasive alien species (IAS) pose a threat to native European biodiversity and cost the EU annual damages worth EUR 12 billion as a result of IAS effects on human health, damaged infrastructure, and agricultural losses. IAS are the focus of Target 9 of the Convention of Biological Diversity (CBD) and Target 5 of the EU Biodiversity Strategy: ‘By 2020, IAS and their pathways are identified and prioritised… pathways are managed to prevent the introduction and establishment of new IAS.’ The EU framework for action against IAS is set out in a Regulation adopted in 2014. This provides for the adoption of a list of IAS of Union concern that will be subject to restrictions across the EU. The first step in order to consider a species for listing is to undertake a risk assessment. Full Article
al Woody networks in agricultural landscapes provide refuge for intrinsic and functional biodiversity By ec.europa.eu Published On :: Thur, 25 Oct 2018 13:11:19 GMT Woody networks in agricultural landscapes are known to harbour high intrinsic biodiversity (i.e. diversity of plant species) and functional biodiversity (i.e. ecosystem services that arise from biodiversity). In order to clarify the drivers of intrinsic and functional biodiversity in woody networks, researchers analysed the plant species diversity, pollinator resource value (PRV), and potential edibility value (PEV) of a woody network in northern Belgium. The analysis confirmed that woody elements are a rich source of intrinsic and functional biodiversity and identified several important drivers. From a policy perspective, this research highlights the value of protecting existing woody elements and thoughtfully designing and locating new ones to maximise intrinsic and functional biodiversity in the countryside.
