Designing Burn Windows for Integrated Fire Management in Wetlands: Why Should Flooding Not Be Overlooked?
Year: 2025
Changes in natural wildfire patterns can cause significant impacts on biodiversity, health, and economies. This has sparked discussions on better fire management. One strategy used by countries is Integrated Fire Management (IFM), with prescribed burning as one of the main tools. Prescribed burns effectively depend on specific burn windows. These windows, defined as flood-free areas like savannas, may not suit wetlands due to the influence of flooding on factors like fuel availability. We examined how hydrological patterns affect burn windows in wetlands, using the Pantanal as a model—the…

Mobile radar provides insights into hydrologic responses in burn areas
Year: 2025
Background. Wildfires often occur in mountainous terrain, regions that pose substantial challenges to operational meteorological and hydrologic observing networks. Aims. A mobile, postfire hydrometeorological observatory comprising remote-sensing and in situ instrumentation was developed and deployed in a burnt area to provide unique insights into rainfall-induced post-fire hazards. Methods. Mobile radar-based rainfall estimates were produced throughout the burn area at 75-m resolution and compared with rain gauge accumulations and basin response variables. Key results. The mobile radar was…

Wildfires drive multi-year water quality degradation over the western United States
Year: 2025
Wildfires can dramatically alter water quality, resulting in severe implications for human and freshwater systems. However, regional-scale assessments of these impacts are often limited by data scarcity. Here, we unify observations from 1984–2021 in 245 burned watersheds across the western United States, comparing post-fire signals to baseline levels from 293 unburned basins. Organic carbon and phosphorus exhibit significantly elevated levels (p ≤ 0.05) in the first 1–5 years post-fire, while nitrogen and sediment show significant increases up to 8 years post-fire. During peak post-…
