In 2005/06, Chittka's team evaluated the hazard of imported foreign bumblebees sold for commercial pollination in the UK and demonstrated a severe risk of them displacing native pollinators. The impact of this work for the UK environment is significant, since it resulted in a DEFRA policy review, mandatory licensing for using non-native pollinators by Natural England, and legal changes which place a fine of up £5,000 and/or 6 month custodial sentence for the uncontrolled use of such pollinators. As a result, all major commercial providers of pollinators now sell a UK native subspecies of bumblebee, Bombus terrestris audax.
Research conducted by Professor Butt at Swansea University has led to significant environmental and economic impacts. It has provided evidence critical to the successful registration and commercialisation of the fungus Metarhizium anisopliae as a biocontrol agent in Europe and North America for insect pests, thereby enabling a reduced dependency on chemical pesticides. Insect pests cause £billions of crop losses globally; this is projected to increase due to intensified farming, pesticide resistance and climate change. Many chemical pesticides have been withdrawn due to the risks they pose to human health and the environment, creating a need for benign alternatives. A novel risk assessment showed that the risk to human and animal health was minimal, as metabolites generated by these fungi did not enter the food chain. Furthermore, the data and risk assessment methodology developed have been used by industry and regulatory authorities (such as the European Food Safety Authority) to make informed decisions about the safety of fungal biocontrol agents.
Irish, UK and European policy and legislation intended to mitigate the ecological damage and economic costs of invasive alien species (IAS) has been influenced by our inter-governmental Invasive Species Ireland project. Legislation was enacted through the Wildlife Order (NI) 1985 (as amended) and the EC (Birds and Natural Habitats) Regulations 2010. Our assessments on the `Killer Shrimp' Dikerogammarus villosus contributed to the EU strategy on IAS. Our Controlling Invasive Riparian Species project removed invasive plants from over 600 km of riverbank in Ireland and Scotland, restoring native biodiversity, and is cited as a best practice case study in the IAS Strategy for Northern Ireland.
York research developed the essential common ground of our understanding of invasive alien species, highlighting their effects on biodiversity and their economic costs. The conceptual frameworks developed at York underpin all subsequent policies and practical strategies in 2008-2013, including the Convention on Biological Diversity (CBD), whose 193 signatory countries are legally bound to "prevent the introduction of, control or eradicate those alien species which threaten ecosystems, habitats or species". UK and international policies and strategies to prevent new introductions and control established aliens stem directly from York research.
Professor Gowing and his associates' research demonstrated the sensitivity of grassland species to soil moisture regime. They developed a method for quantifying the relationship between plant community composition and soil moisture regime which showed that controlling water levels in traditional ways led to conservation of important plant species and/or enhanced diversity. This research led to the Environment Agency issuing practical guidelines to site managers for these internationally important sites, with a lead section written by Gowing. Advice has been given directly to owners and managers via the Floodplain Meadows Partnership led by the OU, engendering parallel studies abroad.
Harmful Algal Blooms (HABs) are a serious risk to human health and the sustainability of the aquaculture industry. Research by Prof. Davidson has improved understanding of temporal and spatial trends in marine HABs and detection of toxins in farmed shellfish. Knowledge gleaned from this research has been adopted by the Food Standards Agency (FSA) in the design of the HAB Monitoring Programme for Scotland. Prof. Davidson leads the FSA HAB Monitoring Programme. The research findings also underpin the Crown Estate's finfish monitoring programmes and are used to advise aquaculture businesses on ways to reduce economic impact of HAB events.
The Large Blue butterfly, formerly extinct in the UK, was successfully reintroduced over two decades to sites in south-west England. New research at the University of Oxford has greatly improved its conservation status and identified key factors that determine the ability of this extreme specialist to survive, especially in the context of climate change. Since 2008 this has led directly to new, larger and more stable populations, to significant expansion of the butterfly's range into cooler regions, and to new `races' with greater environmental tolerance. The research has thus contributed directly to the positive upgrading of this species' global conservation status.
The Sinai Baton Blue is the world's smallest butterfly, and is restricted to the St. Katherine Protectorate in the South Sinai region of Egypt. Research by Francis Gilbert's group on climate change and biodiversity in Egypt surveyed populations of the butterfly for the first time and ensured it received IUCN Critically Endangered status. The butterfly became the focus of biodiversity awareness campaigns in Egypt: appearing on a stamp, in Government-backed educational programmes in schools, and as the flagship species for conservation in Egypt's most important National Park. Current work contributes to international conservation of this extremely rare species and its host-plant, respecting indigenous Bedouin knowledge, benefitting their tribal community, and ensuring international conservation strategies incorporate local pastoralist traditions to sustain the genetic diversity of the planet.
Research on the population biology of the stag beetle at Royal Holloway has created impact on the environment (species conservation through an increase in available habitat and in known breeding sites), impact on public policy (production of a species action plan and an EU Directive and the management of woodland habitats), and impact on society (change in public understanding). Using a `Citizen Science' approach, over 250 volunteers have engaged with this research in population surveys and over 1,000 have helped to create breeding sites. The research has helped to implement conservation policy decisions in the UK and EU and has produced many public information guides. It also has resulted in a radically revised Joint Nature Conservation Committee (JNCC) national Biodiversity Action Plan (BAP) for the species. Furthermore, the research has created impact on practitioners (through enhancement of teaching practices) and brought practical conservation biology into schools, improving the teaching of the National Curriculum at KS2 and 3.
Research over the last 20 years by Jane Nicklin (née Faull) and her research group has established expertise in fungi, which has led to impacts in three areas: impacts on the licensing of commercial products for the control of insect pests which affect food crops, which have led to a new product being licensed in the US to the benefit of vine growers; impacts on heritage conservation, where the work has benefitted English Heritage, the National Trust and many other conservation groups; and impacts on public awareness and media engagement with science, in particular through her work with Channel 4's How Clean is your House? in 2009.
