Long-term vegetation response following post-fire straw mulching

Publications Posted on: September 14, 2019
Background: Straw mulching is one of the most common treatments applied immediately post fire to reduce soil erosion potential and mitigate post-fire effects on water quality, downstream property, and infrastructure, but little is known about the long-term effects on vegetation response. We sampled six fires that were mulched between 9 and 13 years ago in western US dry conifer forests.

Influence of fire refugia spatial pattern on post-fire forest recovery in Oregon’s Blue Mountains

Publications Posted on: August 06, 2019
Context: Fire regimes in many dry forests of western North America are substantially different from historical conditions, and there is concern about the ability of these forests to recover following severe wildfire. Fire refugia, unburned or low-severity burned patches where trees survived fire, may serve as essential propagule sources that enable forest regeneration.

Spatial patterns of ponderosa pine regeneration in high-severity burn patches

Science Spotlights Posted on: August 25, 2017
Over the past three decades, wildfires in southwestern United States ponderosa pine forests have increased in size and severity, leaving large patches of tree mortality. Ponderosa pine evolved under fire regimes dominated by low- to moderate-severity wildfires, and they are poorly adapted to regenerating in large patches of high-severity fire. There is concern about these high-severity burn patches because the lack of seed-producing trees can prevent or significantly delay ponderosa pine regeneration.

Tree regeneration following severe wildfire in southwestern and southern Rocky Mountain ponderosa pine forests

Projects Posted on: August 24, 2016
Wildfire has long been an important and complex disturbance agent in forests dominated by ponderosa pine in the western United States. However, many recent fires have burned with increased severity across large, contiguous areas, resulting in vast expanses with no surviving overstory trees. Researchers are looking at regeneration rates inponderosa pine forests after high-severity fires and examining the spatial patterns and environmental conditions in affected areas to help managers anticipate natural recovery and plan for post-fire management activities.

Post-fire conifer regeneration in severely burned southern Rocky Mountain ponderosa pine forests

Science Spotlights Posted on: August 18, 2016
Wildfire is an important disturbance in ponderosa pine forests of the southern Rocky Mountains, but the past two decades have witnessed fires of increased severity. The severely burned portions of these fires are generating concern about forest resilience, as there is uncertainty about ponderosa pine’s ability to regenerate in areas where no surviving trees remain.

Patterns of conifer regeneration following high severity wildfire in ponderosa pine - dominated forests of the Colorado Front Range

Publications Posted on: August 10, 2016
Many recent wildfires in ponderosa pine (Pinus ponderosa Lawson & C. Lawson) - dominated forests of the western United States have burned more severely than historical ones, generating concern about forest resilience. This concern stems from uncertainty about the ability of ponderosa pine and other co-occurring conifers to regenerate in areas where no surviving trees remain.

Characteristics of mixed-oak forest ecosystems in southern Ohio prior to the reintroduction of fire

Publications Posted on: May 12, 2016
Contains 12 chapters describing baseline conditions of mixed-oak forest ecosystems in the context of a long-term study of prescribed fire effects.

Boise Basin Experimental Forest

Experimental Forests and Ranges Posted on: September 09, 2015
Located near Idaho City, Idaho, the Boise Basin Experimental Forest was established in 1933 to study ponderosa pine management. This experimental forest has been the site of long-term research and data collection on fire, soils, habitat types, and vegetation trends. Current research opportunities include ponderosa pine restoration, the urban-rural interface, and recreation.

Tree regeneration in high-severity burn patches in southwestern ponderosa pine forests

Projects Posted on: April 13, 2015
Numerous factors influence the establishment and growth of tree seedlings after high-severity wildfires. Understanding spatial patterns and environmental conditions influencing ponderosa pine and aspen regeneration post-wildfire can help managers monitor natural recovery.
