Fire can be a significant driver of permafrost change in boreal landscapes, altering the availability of soil carbon and nutrients that have important implications for future climate and ecological succession. However, not all landscapes are equally susceptible to fire-induced change. As fire frequency is expected to increase in the high latitudes, methods to understand the vulnerability and resilience of different landscapes to permafrost degradation are needed. Geophysical and other field observations reveal details of both near-surface (less than 1 m) and deeper (greater than 1 m) impacts of fire on permafrost along 11 transects that span burned-unburned boundaries in different landscape settings within interior Alaska. Data collected along the 11 transect locations include: electrical resistivity tomography (ERT), downhole nuclear magnetic resonance (NMR), active layer thickness (ALT), organic layer thickness (OLT), and plant species cover. These geospatial datasets are the foundation for the journal article, "Evidence for non-uniform permafrost degradation after fire in boreal landscapes", published in the Journal of Geophysical Research - Earth Surface.
Data were collected to quantify the belowground impacts of fire on permafrost in boreal landscapes.

Ocular estimates of vegetation type and abundance were recorded manually in the field, and later digitally transcribed and stored.Plant species cover class was visually estimated within undisturbed and disturbed vegetation zones of each transect. Nomenclature for the vegetation zones (e.g. LTER-U) consists of the site name followed by a zone descriptor, where U is unburned, B is burned, D is drainage, F is fireline, and T is thermokarst. Where multiple vegetation zones within each category occurred, the zones were numbered sequentially.
