Mapping breakthrough with benefits for people and nature

Mapping breakthrough with benefits for people and nature: Segmentation - (C) Getmapping plc/ SNH

The wildlife and landscape of Scotland’s wildest and most remote islands, moorland and mountain ranges are set to be understood as never before, through ground breaking new mapping technology that can help us to tackle climate change and manage our upland habitats.

The innovative method for mapping our upland habitats is being pioneered in the UK by Scottish Natural Heritage (SNH). It uses a technique developed in Sweden known as ‘stereo colour infrared (sCIR) aerial photo interpretation (API), which uses imagery taken from aeroplanes. 

Sally Thomas, SNH’s Director of People & Nature, said: “This technology really is a game changer for our work in some of the remotest parts of Scotland. Healthy peatland is a key factor in tackling climate change. It holds onto carbon, preventing its release into the atmosphere to trap heat from the sun. This cutting edge technique means we can identify prime locations for our peatland restoration work. It can also help us to manage woodland expansion, and it’s great news for protecting our diverse upland habitats: as well as the widespread heaths and bogs there are many small, fragmented and internationally rare habitats, such as important calcareous grasslands and juniper scrub.”

Using high resolution imagery with infrared information reveals colour and texture differences in vegetation. A range of indicators reveal detailed habitat such as blanket bog, wet grasslands and bracken. SNH has developed this technique for upland habitats and tested the method on a wide range of habitat types.

The report of the successful pilot, which took place over two 100 km2 areas in the Cairngorms and near Beinn Eighe National Nature Reserve, was announced at a major conference on geographic mapping and analysis in Perth today.

Kath Leys, Ecosystems & Biodiversity Manager for SNH said: “There are around three million hectares of upland habitat still to be mapped – about one third of Scotland. Using current field based methods this would take a large team of surveyors many years, due to the short season when they can get out on the ground in these remote areas, whereas this more desk based approach can continue throughout the year. Our pilot of this cutting-edge technique has delivered accurate results much more quickly and at less than half the cost.”

SNH is leading a multi-partner project to produce a comprehensive Habitat Map of Scotland (HabMoS). Partners in the HabMoS project are currently considering the next steps to secure funding to complete the upland mapping work.

Notes to editors

  • The HabMoS project is a major contribution to the Scottish Government’s 2020 Challenge for Biodiversity and, together with the UK SeaMap, will in time provide a complete picture of all of Scotland’s habitats.
  • 22 of the 52 Scottish terrestrial habitats protected under the EC Habitats Directive are found in upland areas.
  • The method continues to be developed as part of the Collaborative Action for the Natura Network (CANN) project, a collaborative project between Scotland Northern Ireland and Southern Ireland 
  • The pilot project has taken forward the method previously described in the SNH Research Report 767 Trial mapping of upland Annex I and EUNIS habitats using stereo colour near-infrared aerial imagery published in February 2017.

Scottish Natural Heritage is Scotland's nature agency. We work to improve our natural environment in Scotland and inspire everyone to care more about it. So that all nature in Scotland - our key habitats and landscapes, all our green space and our native species - is maintained, enhanced and brings us benefits. It is the job of all of us to achieve a balance in the sensitive management of our natural world in order to maintain and enhance biodiversity.

'S e Dualchas Nàdair na h-Alba buidheann nàdair na h-Alba. Tha sinn ag obair airson ar n-àrainneachd nàdarra ann an Alba a thoirt am feabhas agus a h-uile duine a bhrosnachadh gus barrachd cùraim a ghabhail dhi. Gus am bi an nàdar air fad ann an Alba – ar prìomh àrainnean is chruthan-tìre, ar n-àiteachan uaine gu lèir is ar gnèithean dùthchasach - air an gleidheadh, air an leasachadh 's a' toirt bhuannachdan dhuinn. 'S e an dleastanas a th' oirnn uile co-chothrom ann an stiùireadh faiceallach ar saoghail nàdarra a ruighinn airson bith-iomadachd a ghleidheadh 's a leasachadh.
