Repeated fall prescribed fire in previously thinned Pinus ponderosa increases growth and resistance to other disturbances

Year of Publication
2021
Publication Type

In western North America beginning in the late 19th century, fire suppression and other factors resulted in denseponderosa pine (Pinus ponderosa) forests that are now prone to high severity wildfire, insect attack, and rootdiseases. Thinning and prescribed fire are commonly used to remove small trees, fire-intolerant tree species, andshrubs, and to reduce surface and aerial fuels.

The effects of thinning and burning on understory vegetation in North America: A meta-analysis

Year of Publication
2017
Publication Type

Management in fire-prone ecosystems relies widely upon application of prescribed fire and/or fire-surrogate (e.g., forest thinning) treatments to maintain biodiversity and ecosystem function. The literature suggests fire and mechanical treatments proved more variable in their effects on understory vegetation as compared to their effects on stand structure.

Seasonal variation in surface fuel moisture between unthinned and thinned mixed conifer forest, northern California, USA

Year of Publication
2012
Publication Type

Reducing stand density is often used as a tool for mitigating the risk of high-intensity crown fires. However, concern has been expressed that opening stands might lead to greater drying of surface fuels, contributing to increased fire risk. The objective of this study was to determine whether woody fuel moisture differed between unthinned and thinned mixed-conifer stands.

Ecological effects of alternative fuel-reduction treatments: highlights of the National Fire and Fire Surrogate study (FSS)

Year of Publication
2012
Publication Type

The 12-site National Fire and Fire Surrogate study (FFS) was a multivariate experiment that evaluated ecological consequences of alternative fuel-reduction treatments in seasonally dry forests of the US. Each site was a replicated experiment with a common design that compared an un-manipulated control, prescribed fire, mechanical and mechanical + fire treatments.

Simulating fuel treatment effects in dry forests of the western United States: testing the principles of a fire-safe forest

Year of Publication
2011
Publication Type

We used the Fire and Fuels Extension to the Forest Vegetation Simulator (FFE-FVS) to simulate fuel treatment effects on 45 1 62 stands in low- to midelevation dry forests (e.g., ponderosa pine (Pinus ponderosa Doug!. ex. P. & C. Laws.) and Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) of the western United States.

Assessing Fuel Treatment Effectiveness After the Tripod Complex Fires

Year of Publication

Publication Type

Over the past 50 years, wildfire frequency and area burned have increased in the dry forests of western North America. To help reduce high surface fuel loads and potential wildfire severity, a variety of fuel treatments are applied. In spite of the common use of these management practices, there have been relatively few opportunities to quantitatively measure their efficacy in wildfires.
