Fire and rain: A systematic review of the impacts of wildfire and associated runoff on aquatic fauna

Daniel F. Gomez Isaza et al.

Summary: This article systematically reviews the responses of aquatic animals to wildfire disturbances. By studying and summarizing literature, it is found that wildfires can cause complex ecological and physiological changes in aquatic fauna and their ecosystems, and several methods and tools are mentioned for assessing the impacts of wildfires on aquatic animals.

Biogeomorphic influences on river corridor resilience to wildfire disturbances in a mountain stream of the Southern Rockies, USA

Ellen Wohl et al.

Summary: This study examines the sediment storage and spatial heterogeneity in a montane river corridor after a wildfire. The findings suggest that wider portions of the river corridor with multithread channels have greater spatial heterogeneity, larger volumes of logjam backwater storage, and finer sediment storage. Despite significant turnover of sediment in the first runoff season after the wildfire, the cumulative sediment volume at monitored logjams reached 71% of the volume immediately after the fire. Vegetation recovery in multithread reaches was faster and more complete, contributing to overbank deposition. The results highlight the disproportionate importance of spatially heterogeneous river corridors in attenuating sediment inputs following wildfires.

Cascadia Burning: The historic, but not historically unprecedented, 2020 wildfires in the Pacific Northwest, USA

Summary: Wildfires in 2020 caused significant damage to communities in Oregon and Washington, burning a large area of forest. The temperate rain forests of the Pacific Northwest, which rarely experience fires, require a scientific evaluation of the fires and strategies to adapt to future events.

The effects of forest management on water quality

Nadeem W. Shah et al.

Summary: Water quality in forested watercourses is generally high, but forest management can have detrimental effects on water quality and freshwater ecology. This review focuses on the impacts of various forestry activities on water quality, including cultivation, fertilisation, and harvesting. The literature shows that forest operations can lead to sediment delivery, nutrient losses, carbon transport, metal and base cation releases, and changes in acidity and temperature. It is important to consider spatial and temporal resolution, as local-scale changes may not be observed at the catchment level and the effects of operations can manifest many years later. Best management practices, such as the use of buffers and low impact techniques, have reduced and prevented impacts on water quality. Future technological, methodological, and climatic developments may further alter the effects of forest management on water quality.

Use of geostatistical models to evaluate landscape and stream network controls on post-fire stream nitrate concentrations

Allison E. Rhea et al.

Summary: Forested watersheds are important for providing ecosystem services, but they are increasingly threatened by wildfires. This study investigated the drivers of persistently elevated nitrate (NO3-) concentrations in burned watersheds and found that vegetation cover and landscape characteristics play a significant role. Additionally, targeted reforestation in severely burned areas may help restore stream nitrate concentrations.

Heat and smoke from wildfires influence water temperature and dissolved oxygen levels in headwater streams

Ashley M. M. Sanders et al.

Summary: Wildfires in forested landscapes in the western United States have become more frequent and severe, affecting stream parameters and water quality. The study reveals that stream temperature and dissolved oxygen are significantly influenced by the fire and smoke, and the impact of the fire on streams correlates with burn severity.

Loss of riparian forests from wildfire led to increased stream temperatures in summer, yet salmonid fish persisted

Dana R. Warren et al.

Summary: This study examines the impacts of climate change and abrupt disturbances such as wildfires on native salmonid fishes. It is found that wildfires can lead to substantial increases in stream temperature, yet populations of cold-water fishes are able to persist despite the drastic changes, with unclear mechanisms requiring further investigation.

Wildfire in western Oregon increases stream temperatures, benthic biofilms, and juvenile coastal cutthroat trout size and densities with mixed effects on adult trout and coastal giant salamanders

Allison Swartz et al.

Summary: Wildfire has a significant impact on aquatic ecosystems, increasing stream temperatures and algae abundance. However, fish responses vary depending on age class and severity of the fire.

Fire reduces riverine DOC concentration draining a watershed and alters post-fire DOC recovery patterns

Xinyuan Wei et al.

Summary: Fires can significantly impact the flux of dissolved organic carbon (DOC) from soils, leading to an immediate decrease in riverine DOC concentration draining the watershed by 26 +/- 15%, with an average recovery time of approximately 9 months. The larger the proportion of the watershed that burned, the greater the concentration decrease and the longer the post-fire recovery period.

Compound Extremes Drive the Western Oregon Wildfires of September 2020

John T. Abatzoglou et al.

Summary: The large high-impact fires in western Oregon in September 2020 were caused by a combination of dry air intrusion and strong east winds. These compound extremes were unmatched in the observational record, highlighting the importance of assessing wildfire hazard risk with a multivariate lens.

Relating pre-fire canopy species, fire season, and proximity to surface waters to burn severity of boreal wildfires in Alberta, Canada

Prabha Amali Rupasinghe et al.

Summary: Increased global temperature has led to more frequent and intense wildfires in Canadian Boreal forests. Research shows that a higher proportion of coniferous species in the canopy can result in greater burn severity, while fires occurring at a greater distance from water bodies tend to be more severe.
