NatureScot Research Report 1325 - Review of high-resolution remote sensing methods to monitor peatland restoration efficacy on actively eroding blanket bogs.
Abstract
This report explores high-resolution remote sensing methods to monitor peatland restoration, particularly on actively eroding blanket bogs, as part of the Peatland ACTION programme in Scotland. It aims to develop a standard methodology to complement field-based monitoring by assessing a range of remote sensing technologies, including satellite imagery, UAVs, and LiDAR, to detect and quantify erosion activity and restoration efficacy. The report evaluates each technology using criteria such as resolution, accuracy, cost, and repeatability, ultimately identifying the most suitable methods for monitoring peatland features at a sub-metre scale. Key findings highlight that while satellite data offers broad coverage, its resolution is insufficient for detailed peatland analysis, whereas UAVs provide high-resolution data but are limited in scale and cost. LiDAR, particularly when combined with UAV or fixed-wing platforms, offers the most accurate 3D elevation data for monitoring peatland restoration. The findings inform peatland restoration practitioners on best practices for remote sensing and its integration with on-the-ground monitoring.
