Mapping and understanding the vulnerability of northern peatlands to permafrost thaw at scales relevant to community adaptation planning

This article is directly focused on the Taiga Plains and discontinuous permafrost zone in the NWT and provides community-scale mapping tools to support land-use planning, infrastructure decisions, and climate adaptation.

Summary Developing spatially explicit permafrost datasets and climate assessments at scales relevant to northern communities is increasingly important as land users and decision makers incorporate changing permafrost conditions in community and adaptation planning. This need is particularly strong within the discontinuous permafrost zone of the Northwest Territories (NWT) Canada where permafrost peatlands are undergoing rapid thaw due to a warming climate. Current data products for predicting landscapes at risk of thaw are generally built at circumpolar scales and do not lend themselves well to fine-scale regional interpretations. Here, we present a new permafrost vulnerability dataset that assesses the degree of permafrost thaw within peatlands across a 750 km latitudinal gradient in the NWT.
