Human Mediation of Wildfires and Its Representation in Terrestrial Ecosystem Models
Year: 2025
Increasing wildfires are causing global concerns about ecosystem functioning and services. Although some wildfires are caused by natural ignitions, it is also important to understand how human ignitions and human-related factors can contribute to wildfires. While dynamic global vegetation models (DGVMs) have incorporated fire-related modules to simulate wildfires and their impacts, few models have fully considered various human-related factors causing human ignitions. Using global examples, this study aims to identify key factors associated with human impacts on wildfires and provides…

Long-term soil nutrient and understory plant responses to post-fire rehabilitation in a lodgepole pine forest
Year: 2025
Wildfires and other disturbances play a fundamental role in regenerating lodgepole pine forests. Though severe, stand-replacing fires are typical of this ecosystem, they can have dramatic impacts on soil properties and biogeochemical processes that influence the rate and composition of vegetation recovery. Organic soil amendments are often applied to manage post-fire erosion, but they can also improve soil moisture and nutrient retention and potentially alter the trajectory of post-fire revegetation. We compared change in soil nutrients, microbial communities, and understory plant cover and…

Role of biochar made from low-value woody forest residues in ecological sustainability and carbon neutrality
Year: 2024
Forest management activities that are intended to improve forest health and reduce the risk of catastrophic fire generate low-value woody biomass, which is often piled and open-burned for disposal. This leads to greenhouse gas emissions, long-lasting burn scars, air pollution, and increased risk of escaped prescribed fire. Converting low-value biomass into biochar can be a promising avenue for advancing forest sustainability and carbon neutrality. Biochar can be produced either in a centralized facility or by using place-based techniques that mitigate greenhouse gas emissions and generate a…
