🌳 These heterogeneous burn areas contain small unburned patches that may be crucial for post-fire vegetation recovery.
🏞️ Pre-fire topography and vegetation conditions were key predictors for burn patterns, offering potential improvements for future fire spread models.

🛰️ We used high-resolution (3 m) satellite imagery to map patchy tundra fire scars from the extreme 2020 Siberian fire season.
🔍 Our fine-scale analysis revealed mixed burned/unburned areas missed by previous studies, potentially underestimating fire effects like carbon emissions.

Thank you, Robert!

Thanks a lot for this Pack! Could you add me as well, please?

We call for future studies to address possible tundra ecosystem shifts linked to fires, using methods that cover greater temporal and spatial scales.

We hypothesise that post-fire tundra recovery, coupled with climate change, may not return to pre-fire conditions.
We propose two climate-fire driven trajectories:
1) Low fire frequency 🔥: Increased woody vegetation 🌳
2) High fire frequency 🔥🔥🔥: Grass dominance 🌾

Our review synthesises current knowledge on post-fire vegetation cover trajectories in Arctic tundra ecosystems:
