Soil water repellency (SWR) is a physical property due to a complex interaction of factors (e.g., fire, soil organic matter, soil texture) that reduces the soil water infiltration capacity. Traditionally, SWR is attributed to the accumulation and…

Year Published:

In the western US, wildfires are modifying the structure, composition, and patterns of forested landscapes at rates that far exceed mechanical thinning and prescribed fire treatments. There are conflicting narratives as to whether these wildfires…

Year Published:

Wildfire activity is increasing in the western United States at a time when outdoor recreation is growing in popularity. Because peak outdoor recreation and wildfire seasons overlap, fires can disrupt recreation and expose people to poor air quality…

Year Published:

Wildfire is an integral part of many ecosystems, and wildland fires also have the potential for costly impacts to human health and safety, and damage to structures and natural resources. Public land managers use various strategies for managing…

Year Published:

Natural disturbances serve as a driver of change, creating complexity and heterogeneity across the landscape. Ecological patterns and processes that arise from the impacts of disturbance determine the plant and animal species a landscape supports…
