Wildfire and post-fire salvage logging alter forest structure, but consequences for wildlife are uncertain. We examined forest-specialist Pacific marten (Martes caurina) on three recently-burned landscapes in Washington and British Columbia. Marten selected lightly-burned sites with overhead cover and high structural complexity, but avoided severely-burned and salvage-logged sites lacking these features.

WF21112The role of decomposer communities in managing surface fuels: a neglected ecosystem service

H. Gibb, J. J. Grubb, O. Decker 0000-0002-6280-697X, N. Murphy 0000-0002-0907-4642, A. E. Franks and J. L. Wood
pp. 350-368

Ground fuels (leaf litter and logs) are important in forest fires, but how decomposer organisms (invertebrates, fungi and bacteria) affect fuel breakdown is rarely considered. We review the evidence for the importance of decomposer organisms and its regulation by global change, highlighting knowledge gaps and the way forward.

Graphical Abstract Image

In this paper, wireless sensor network and back-propagation neural network were used to estimate the dead fine fuel moisture content (FFMC) of forest surface. The method can be well applied to forest surface dead FFMC estimation and early fire danger assessment, having practical significance for forest fire protection.

WF21143Simulation-based high-resolution fire danger mapping using deep learning

We propose a new method for short-term fire danger mapping using deep learning based on simulated fire sizes. High-resolution maps can be obtained in a few hours using actual weather forecasts and terrain data. Application to 13 fire cases shows relevant predictions of potential for fire spread.


Pyrogenic carbon (PyC), generated by fire, acts as a stable carbon deposit and is stored in the peatland soil carbon pool. PyC chemical compositions and thermal stability are significantly affected by burning temperature and fuel sources, and can be used to identify PyC sources and fire intensity.

WF21141Comparison of fire-produced gases from wind tunnel and small field experimental burns

Pyrolysis measurements from simplified fuel beds in a wind tunnel were compared with pyrolysis measurements collected during prescribed burns in longleaf pine. Compositional data techniques were applied to predict gas composition of pyrolysis or flaming combustion samples. Relative dominance of some gases differed between wind tunnel and field measurements.


There is a growing interest in connecting fire science and management through processes like co-production of fire science, which can increase the relevance and utility of research products by integrating diverse knowledge and goals. Research organisations can enable and incentivise co-production through modifications to performance evaluations, funding structures and career ladders.


Statistical learning methods were used to develop predictive models of the likely number and location of daily airtanker and helicopter initial attack targets in British Columbia, Canada, that can inform the day-basing or prepositioning of aircraft to reduce response times.
