Biodiversity under threat

The biodiversity of our natural environment has suffered a continual 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.

The importance of habitat connectivity

Dr Tom Oliver, Associate Professor of Landscape Ecology at the 澳门六合彩开奖记录, is influencing a new approach to conservation. Using butterflies as an indicator species, Tom鈥檚 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 鈥� imagine an island of trees in the middle of intensively farmed arable fields 鈥� leave species vulnerable when conditions change,

He proposes that restoring the 鈥榝unctional connectivity鈥� of habitats will improve the resilience of butterflies and other populations in the face of threats such as extreme weather events. This means providing 鈥榗orridors鈥� or stepping stones of meadows, woodland, flower-rich field margins or road verges, to connect larger areas of habitat to each other.

Dr Oliver has also developed a suite of practical measures of habitat connectivity that may become a standard monitoring method for the , which advises the UK government and Scottish, Welsh and Northern Irish Assemblies.

A paradigm shift

Through his research insights, Dr 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: 鈥淭om鈥檚 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.鈥�

This is illustrated in , published in 2018. It quotes that drew from Dr Oliver鈥檚 research in calling for 鈥榤ore habitat; in better condition; in bigger patches that are more closely connected.鈥�

Evidence for protection

Thanks to experts like Dr Oliver, action is being taken to improve and protect biodiversity in the UK. For example, twelve Government-backed 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鈥檚 third largest lowland raised bog in the meres and mosses of Shropshire and the Welsh Marches

Dr Oliver research continues to generate compelling ecological evidence that informs and influences environmental policy-making nationally and internationally.
