The authors examined the relationship between climate and fire severity across coniferous forests of the western U.S.

The authors conducted a review of long-term and broad-scale trends in aspen cover across the western U.S.

The authors compared treated and untreated areas nine years after the 2002 Rodeo-Chediski Fire to assess how stand structure and surface fuels change over longer periods of time. They further compared this information to a previous study (Strom and Fulé, 2007) that installed the study plots in 2004 to assess the differences between short- and longer-term fuel responses.

The authors reconstructed both regional climate teleconnections (ENSO, PDO, and AMO) and historical fire occurrence using tree-ring analysis. Their objectives were to analyze the relationship between moisture variability and regional, individual and phase combinations of, ENSO, PDO, and AMO and then compare this climate variability to fire occurrence in upper elevation forests across the southwest.

The authors quantified the effects of reintroducing fire to an unlogged, fire?excluded, ponderosa pine forest to examine post-fire trajectories of forest regeneration and stand composition and structure and to see if ponderosa pine forests possess latent resilience to reintroduced fire.

The authors modeled future global fire season severity due to climate change using the Cumulative Severity Rating, a weather-based fire danger metric, of the Canadian Forest Fire Danger Rating System.

The authors modeled the effects of drought on ponderosa pine regeneration in high-severity fire areas using a water balance methodology that assess thermal and moisture conditions at the project sites. They validated their model at five regenerating ponderosa pine stands in the Southwest that burned at high-severity during the drought years 1945 to 1956.

The authors sampled plots eight years post-wildfire that had been thinned and burned under prescription prior to the Rodeo-Chediski fire to examine differences between areas that burned at high and low severity with or without treatments pre-fire. They specifically examined post-fire species composition, exotic species response, and ponderosa pine regeneration.

The authors assessed the relationship between fire severity and stand density using the composite burn index (CBI).

The authors examined ponderosa pine stands using historic General Land Office (GLO) land survey data to reconstruct forest structure and fire regimes of pre-widespread European settlement on the Coconino Plateau and Grand Canyon National Park.
