The 2020 Challenge for Scotland’s biodiversity made a commitment to produce a “comprehensive map of Scotland’s main habitats”.

What is the Habitat Map of Scotland?

The Habitat Map of Scotland (HabMoS) will become the national repository for habitat and land use data. The map adopts internationally recognised data and habitat classification standards.

HabMoS is a composite map. It contains data, from many different sources, which have all been re-classified into EUNIS, the European Nature Information System. If you want to know more about how data were re-classified the correspondence between NVC and EUNIS and Annex I is explained in Scottish Natural Heritage's commissioned report 766: Manual of terrestrial EUNIS habitats in Scotland.

 

Why do we need a Habitat Map of Scotland?

We need this map because although we have a lot of existing data it is spread over many locations, in many different classifications. In order to allow policy and management decisions to be made with the greatest ease we need to have a resource that pulls everything into one place.

The unique feature of the map is that it brings together in one place and in one classification system all available habitat and land use data. It is this ability to view a range of data from different sources which makes it a powerful tool for analysis, planning and policy development at national and local levels.

HabMoS sets a new standard for collaboration within Scotland. Organisations spanning the government; voluntary and private sectors have supplied data in an informal, willing and collaborative partnership.

The map uses European Nature Information System (EUNIS) and Habitats Directive Annex I habitat classifications. At the present time almost 800 site surveys and all existing national habitat surveys have been brought into use. For example, the woodland component is converted from surveys undertaken by Forestry Commission Scotland. The Identity of original surveys is retained, so it is always clear where data has come from.

Explore the data

The Habitat Map of Scotland (HabMoS) data is available to view on this website. There are 8 layers available in HabMoS - view in our map.

HabMoS EUNIS Land Cover Scotland

The HabMoS EUNIS Land cover Scotland (HabMoS ELCS) is a broad scale EUNIS map that provides a seamless coverage. As HabMoS develops it will replace the less detailed information in ELCS. This data is also referenced in the Ecosystem Health Indicators - Condition Indicator for landcover.

HabMoS Coastal and Vegetated Shingle

This data was collected as part of a project to validate, in the field, the Inventory of coastal vegetated shingle in Scotland (2011). The initial inventory drew together existing information sources and updated this through aerial photography interpretation (API) and limited field survey. This project undertook field validation of the inventory and mapped 2 Habitats Directive Annex I types. A report and the data were published in 2014. Scottish Natural Heritage's commissioned report 739: Inventory of coastal vegetated shingle in Scotland – field validation

HabMoS Saltmarsh Survey

The Scottish Saltmarsh Survey collected information on all known saltmarshes larger than 3ha from 2010 - 2012. The report and the data were published in 2016 Scottish Natural Heritage's commissioned report 786: Scottish saltmarsh survey national report. All saltmarsh and brackish swamp was mapped using the NVC (National Vegetation Classification).

HabMoS Sand Dune Vegetation Survey

This data is part of which completed NVC survey of all dunes in Scotland between 1994 and 1998. There is a series of 8 regional reports that cover the whole coast of Scotland. Each report is split into 3 volumes:

  • Volume 1 – main report
  • Volume 2 – site reports;
  • Volume 3 - NVC survey maps

Original survey maps at 1:10000 were also provided. These were later digitised for use in GIS. This data was reclassified in order to map the Annex I habitats and other areas were given a EUNIS code. Coastal environments are very dynamic, so some features may not match background mapping of a later date. It is the best available data.

HabMoS NWSS

The Native Woodland Survey of Scotland (NWSS) was carried out by Forestry Commission Scotland from 2006-2013. It mapped all native woodlands of more 0.5 ha and recorded type and condition. Woodland was defined as an area of trees and shrubs which has a canopy cover. A robust and documented method was used to re-classify the qualifying woodlands as Annex I habitats and to give all woodland a EUNIS code.

HabMoS Freshwater

The freshwater layer uses polygons from OS VectorMap District. These were classified to EUNIS C1 or C2 for standing waters and running waters. The information from the Standing Waters Database has also been used to give some lochs a more detailed classification. This is a database of points for lochs which records aquatic plant species, Lake Assessment for Conservation (LACON) scores, surface area and altitude as well as water chemistry.

HabMoS NVC to Annex I and EUNIS

National Vegetation Classification (NVC) site surveys exist for sites, usually protected areas. They were done for a variety of site management purposes using the National Vegetation Classification and can vary greatly in terms of methodology and scope. This information has been re-classified to map the Annex I habitats. NVC codes that are not Annex I habitats have been re-classified to EUNIS. This process is supported by Scottish Natural Heritage's commissioned report 766: Manual of terrestrial EUNIS habitats in Scotland and a conversion table for each survey. Work is on-going to remove the overlaps in this data.

HabMoS other land use

This layer shows the non-semi natural land uses and helps you to look at the other information in context.

The data is also available to download from the Scottish Natural Heritage data download page – Natural spaces

Some of the data in HabMoS is already available on Scotland’s environment website. For example the Forestry Commission’s Native Woodland Survey of Scotland (NWSS). HabMoS has taken this data and combined it with other geographical data to map Annex I habitats.

The data is managed as separate layers depending on the source of the data. We will work to combine these layers and remove overlaps.
