Experimental treatments for increasing perennial grass cover in a shrub-invaded grassland in the Southwestern Borderlands region of Arizona and New Mexico

Publications Posted on: October 22, 2020
The density of mesquite (Prosopis spp.) and other woody species has increased on desert and semidesert grasslands in the southwestern United States. This increase in woody species has been associated with the decline of native herbaceous plants and a loss of biological diversity and productivity. There have been numerous attempts to reverse this situation.

Limited effects of long-term repeated season and interval of prescribed burning on understory vegetation compositional trajectories and indicator species in ponderosa pine forests of Northeastern Oregon, USA

Publications Posted on: August 17, 2020
Fire exclusion has dramatically altered historically fire adapted forests across western North America. In response, forest managers reduce forest fuels with mechanical thinning and/or prescribed burning to alter fire behavior, with additional objectives of restoring forest composition, structure, and ecosystem processes.

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

Publications Posted on: June 22, 2020
Contains 12 chapters describing baseline conditions of mixed-oak forest ecosystems in the context of a long-term study of prescribed fire effects.

Ethnoecology of Fire: An Experimental Approach in the Ohio Valley

Publications Posted on: June 22, 2020
Native Americans used fire to manipulate nature and directly benefit their survival. Certain plant species, many of which were useful to Native Americans as sources of food, fiber, dye, medicine, and game browse, are adapted to survive and even thrive in post-burn environments. Evidence suggests that Native Americans intentionally set fires to encourage growth and survival of such useful species. Data from a 5-year study conducted by the U.S.

Resistance is not futile: The response of hardwoods to fire-caused wounding

Publications Posted on: June 22, 2020
Fires wound trees; but not all of them, and not always. Specific fire behavior and differences among tree species and individual trees produce variable patterns of wounding and wound response. Our work focuses on the relationships between fire behavior and tree biology to better understand how hardwood trees resist injury to the lower stem and either survive or succumb to low-intensity fire.

Forest structure and fire hazard in dry forests of the Western United States

Publications Posted on: June 22, 2020
Fire, in conjunction with landforms and climate, shapes the structure and function of forests throughout the Western United States, where millions of acres of forest lands contain accumulations of flammable fuel that are much higher than historical conditions owing to various forms of fire exclusion.

Prescribed fire science: the case for a refined research agenda

Publications Posted on: April 07, 2020
The realm of wildland fire science encompasses both wild and prescribed fires. Most of the research in the broader field has focused on wildfires, however, despite the prevalence of prescribed fires and demonstrated need for science to guide its application. We argue that prescribed fire science requires a fundamentally different approach to connecting related disciplines of physical, natural, and social sciences.

How to estimate tree mortality resulting from underburning

Publications Posted on: July 31, 2019
Prescribed burning beneath standing timber is widely used to accomplish objectives such as preparing land for reforestation, reducing fuels, improving livestock range, and modifying wildlife habitat. Such burning is usually guided by written plans that set forth general objectives and a firing pattern to accomplish them.

Managing habitats for white-tailed deer in the Black Hills and Bear Lodge Mountains of South Dakota and Wyoming

Publications Posted on: February 26, 2019
The white-tailed deer is one of the most studied animals in North America, yet much of the available information has been derived in ecosystems different from the Black Hills. The Black Hills are unique in that the dominant species, ponderosa pine, has excellent regenerative abilities.
