The Response of Thurber’s Needlegrass to Fall Prescribed Burning

, 2008
Thurber’s needlegrass (Achnatherum thurberianum [Piper] Barkworth) is an important component of many sagebrush communities in the Intermountain West. Prescribed fall burning is often implemented in sagebrush plant communities to mimic historic wildfires,

Perceptions of Prescribed Fire Among Ranchers near Northern US National Grasslands

Fire
Many barriers prevent ranchers from supporting prescribed fire on grazing leases or their own land. Barriers include negative perceptions of fire resources limitations, and fear of liability.

Understanding the effects of patch‐burn grazing management on aboveground grassland invertebrate biodiversity

Oikos, EarlyView.
Landscape heterogeneity is widely recognized as a driver of biodiversity, yet its consequences for above‐ground, foliage‐dwelling insect communities under active grassland management remain underexplored. Patch‐burn grazing (PBG), which rotates fire across patches within a grazed landscape, is designed to promote spatial and temporal heterogeneity by ...

The Role of Weeds as Fuels in Prescribed Burning

Tropics, 2005
Fuels have an important role in fires in forest areas (plantation). Most of the fires that destroy forest plantations are cause by excessive fuels stored in the forest plantation. Those fuels consist mostly of the dead and live fuels (weeds). A live fuel can significantly increase fire risk especially in plots which have predominantly young vegetation ...

Wildfires in the Cape floristic region : exploring vegetation and weather as drivers of fire frequency

, 2009
Includes bibliographical references (leaves 68-76).This study assessed the spatial and temporal patterns of wildfires in the Cape Floristic Region (CFR). It focused on the factors that influence fire frequency; namely vegetation age, ignition sources and

Suppression of soil microbiota rather than neighbours facilitates absinthe Artemisia absinthium invasion in native grasslands

Oikos, EarlyView.
Many mechanisms can lead to successful plant invasion, but their importance is often context dependent. One such mechanism is allelopathy: chemical inhibition of neighbouring plants. The importance of allelopathy may be mediated by soil microbiota and environmental conditions, and depend upon the species or functional group affected.

Why do we burn? Examining arguments underpinning the use of prescribed burning to manage wildfire risk

People and Nature, EarlyView.
Abstract Managing wildfire risk requires consideration of complex and uncertain scientific evidence as well as trade‐offs between different values and goals. Conflicting perspectives on what values and goals are most important, what ought to be done and what trade‐offs are acceptable complicate those decisions.
