Abstract
The Peatlands of Wales map series provides an updated distribution of Welsh Peatlands (to 2022) based on current evidence sources. The data layers were created on a 50m grid whereby the presence and thickness of peat are elucidated from a range of sources for each 50m grid cell across Wales. A peatland evidence score defines the level of confidence in the presence of peat in any given grid cell, with those cells scoring more than 2 on this scale of 1-10, captured in the ‘Peatlands of Wales’ peat distribution map. This dataset shows the carbon stock levels across the Peatlands of Wales area. All deep peats are assigned to one of 6 peat soil series. Carbon stocks are calculated from standardised profiles from the Cranfield University HORIZON datasets. The mean carbon stock levels (tonnes) within each cell was then calculated from the carbon stock to 150cm in kg/m2 from the standard profile data adjusted by the thickness of peat in the profile and then multiplied by the area in m2.  This map shows the carbon stock per unit area plus the total carbon stock in each polygon. Full details of the sources of data used to build this map as well as the methodologies used to define the level of evidence for the presence of peat and derivation of the peat evidence score as well as estimates of peat thickness (depth), carbon stock estimates and greenhouse gas emissions are presented in the Peatlands of Wales mapping methodology report.

Purpose
For effective targeting and monitoring of peatland restoration, a baseline of the peatland area is required. The Peatland of Wales map represents a compilation of existing data sources that map the Peatland areas in Wales, and estimates carbon stock (store).

Supplemental Information
The carbon stock was reported in kg/m2, to calculate the total stock within the Peatland of Wales area this was multiplied by the area of the cell in m2 and multiplied by 0.001 to convert the stock to tonnes per 50m cell. The Carbon stock for each 50m cell was derived using an estimate of the carbon stock derived from standardised profile data using carbon concentration and bulk density from LandIS Soil horizon data for. Where the carbon stock had been measured, during the Peatland Depth and Bulk Density Survey (SPEP 2020-21/06) performed by ADAS, the measured carbon stock was given.
