Nature Scot (NS) has prepared a consolidated spatial dataset of peat depth measurement collected across Scotland. The information was collected during peat depth surveys conducted as part of various assessments carried out on sites that formed part of the Peatland ACTION project (2013-2023).Surveys were conducted using the Peat depth survey guidance (https://www.nature.scot/doc/peatland-action-peat-depth-and-peat-condition-survey-guidance-and-recording-form-guidance) issued by Peatland Action program. The current version of the dataset provides all available data on 01 June 2023. Additional datasets will be added to the database when they become available.The surveys were conducted at a high spatial resolution (100 m grid) over a wide geographical spread of the sites across Scotland.The current version includes data collected from 338 projects with over 90,000 individual survey points.The average peat depth across all 338 projects is 1.35m with a maximum depth of 15.2m.
