A Case Study of Nitrogen Saturation in Western U.S. Forests

The Scientific World Journal, 2001
Virtually complete nitrification of the available ammonium in soil and nitrification activity in the forest floor are important factors predisposing forests in the San Bernardino Mountains of southern California to nitrogen (N) saturation.

Prediction of Fire Propagation in Forest Areas using Genetic Algorithm [PDF]

ITM Web of Conferences, 2020
Forest fire causes significant damages to environment and living organisms. It becomes troublesome to recover from the consequences of forest fire. The early and accurate prediction of forest fire propagation in forest area will help in fire management ...

Populus tremuloides seedling establishment: An underexplored vector for forest type conversion after multiple disturbances [PDF]

, 2017
Ecosystem resilience to climate change is contingent on post-disturbance plant regeneration. Sparse gymnosperm regeneration has been documented in subalpine forests following recent wildfires and compounded disturbances, both of which are increasing.

Short-Term Belowground Responses to Thinning and Burning Treatments in Southwestern Ponderosa Pine Forests of the USA [PDF]

, 2016
Microbial-mediated decomposition and nutrient mineralization are major drivers of forest productivity. As landscape-scale fuel reduction treatments are being implemented throughout the fire-prone western United States of America, it is important to ...

Incorporating Short-Term Forecast Mean Winds and NWP Maximum Gusts into Effective Wind Speed for Extreme Weather-Aware Wildfire Spread Prediction

Fire
Because wildfire spread is strongly influenced by instantaneous gusts, models that use only mean wind speed typically underestimate spread. In contrast, incorporating suppression effects often leads to overestimation.

Reproduction of Smaller Wildfire Perimeters Observed by Polar-Orbiting Satellites Using ROS Adjustment Factors and Wildfire Spread Simulators

Remote Sensing
While geostationary satellites can provide continuous near-real-time observations, their low spatial resolution makes it difficult to detect small wildfires.
