Research at the University of Reading is shaping a new approach in environmental policy-making, to create twenty-first-century landscapes that are fit for wildlife.\u00a0<\/span><\/p>\n

Biodiversity under threat<\/h4>\n

The biodiversity of our natural environment has suffered a continuous decline in recent decades. This is caused by factors such as habitat loss through intensive land-use and climate change. As our population grows and the planet warms, conservation strategies must adapt to secure a biodiverse environment for future generations.<\/p>\n

The importance of habitat connectivity<\/h4>\n

Tom Oliver, Professor of Landscape Ecology at the University of Reading, is influencing a new approach to conservation. Using butterflies as an indicator species, Professor Oliver\u2019s research has revealed how the range, arrangement and size of habitats within modern landscapes are vital for biodiversity. Small patches of habitat surrounded by hostile conditions \u2013 imagine an island of trees in the middle of intensively farmed arable fields \u2013 leave species vulnerable when conditions change, for example during drought<\/a>.<\/p>\n

He proposes that restoring the \u201cfunctional connectivity\u201d of habitats will improve the resilience of butterflies and other populations in the face of threats such as extreme weather events. This means providing \u201ccorridors\u201d or stepping stones of meadows, woodland, flower-rich field margins or road verges to connect larger areas of habitat to each other.<\/p>\n

Professor Oliver has also developed a suite of practical measures of habitat connectivity that may become a standard monitoring method for the Joint Nature Conservation Committee<\/a>, which advises the UK government and Scottish, Welsh and Northern Irish Assemblies.<\/p>\n

A paradigm shift<\/h4>\n

Through his research insights, Professor Oliver has helped to bring about a paradigm shift in conservation thinking — towards landscape-scale approaches. Dr Richard Bradbury, Head of Environment at the RSPB, explains: \u201cProfessor Oliver\u2019s work has made an important contribution to shaping environmental and conservation policy and practice in the UK. It has underpinned the drive to move beyond just protected areas and consider whole-landscape conservation, which is of great international importance.\u201d<\/p>\n

This is illustrated in UK Government\u2019s 25 Year Environment Plan<\/a>, published in 2018. It quotes a seminal work by Sir John Lawton<\/a> that drew from Professor Oliver\u2019s research in calling for \u201cmore habitat; in better condition; in bigger patches that are more closely connected.\u201d<\/p>\n

Evidence for protection<\/h4>\n

Thanks to experts like Professor Oliver, action is being taken to improve and protect biodiversity in the UK. For example, 12 government-backed Nature Improvement Areas<\/a> have already been established. These include a project to reinstate open moorland habitat and oak woodland in the Peak District, the restoration of linked habitats across more than 1,000 hectares of wooded valleys and water courses in North Devon and the protection of Britain\u2019s third largest lowland raised bog in the meres and mosses of Shropshire and the Welsh Marches.<\/p>\n

Professor Oliver\u2019s research continues to generate compelling ecological evidence that informs and influences environmental policy-making, nationally and internationally.<\/p>\n
