CNP Grassland Mapping Project 2020-22
This web map and collection of data layers provides information on the location, extent, quality, and condition of species-rich grassland (SRG) sites in the Cairngorms National Park (CNP) - outputs from a joint project between NatureScot and the Cairngorms National Park Authority.
Coverage includes the Spey, Avon, Livet and Dee river catchments.

Data are derived from the following two sources:
(i) CNP grassland mapping 2020 to 2022 - covering the Livet, Avon and Dee
Patches of unimproved/semi-improved grassland were identified and delineated by analysing high-resolution aerial photography. This 'search map' of polygons was then visited in the field by surveyors between 2020 and 2022 who recorded vegetation types using the National Vegetation Classification (NVC), and assessed the presence (or not) of species-rich grassland (SRG). Of 4930 polygons surveyed in total, 1482 (30%) were found to contain at least some species-rich grassland.
The survey polygon layer provides data on the NVC communities recorded in the field and corresponding SRG and non-SRG habitats.
The SRG attribute points layer provides detailed information on the quality and condition of SRG stands encountered during the survey.
(ii) Strathspey inbye survey 2006/2007 - covering the Spey
A selection of fields in Badenoch and Strathspey were surveyed in 2006 and 2007. Vegetation types were recorded using the National Vegetation Classification (NVC). Of 1877 fields surveyed, 815 were found to contain species-rich grassland (SRG) communities.
The resulting GIS datasets were reassessed in 2020/2021 using the most recent available aerial photography to establish the likelihood that SRG was still present and identify potential causes of loss or change.
The survey polygon (540 survey locations with field boundaries) and survey point (275 survey locations with no field boundaries) layers provide data on the NVC communities and corresponding SRG and non-SRG habitats recorded during the original 2006/2007 field survey and the results of the 2020/2021 aerial photo reassessment - likelihood that SRG is still present: high / medium / low.
