- Fire and Bark Beetle Interactions | Springer Nature Link
Fire and bark beetles are similar in that both can cause massive amounts of tree mortality, alter nutrient cycling, and alter forest structure and species composition, but these disturbances, in isolation and together, also have distinct effects on ecosystems
- Bark Beetle and Fire Interactions in Western Coniferous Forests:
Bark beetles can colonize and kill trees of all species, ages, and sizes, but each species exhibits unique host preferences and impacts
- Low-severity fire increases tree defense against bark beetle attacks
These studies suggest that the frequency and severity of disturbance via physical wounding can affect plant defense and influence response to subsequent herbivory
- Fire and Bark Beetle Interactions - US Forest Service
These considerations highlight the important distinction between understanding the effects of fire in beetle-impacted forests for planning and management purposes and the cau-tion needed to safely manage wildland fire for firefighters and the public
- Verdict’s out on beetle-kill fire effects - University of Colorado . . .
It’s hard not to notice the widespread patches of dead trees along the I-70 corridor For many, there is a next logical thought: All those dead trees are going to provide fuel for a wildfire But that conventional wisdom might be wrong
- Low-severity fire increases tree defense against bark beetle attacks
These studies suggest that the frequency and severity of disturbance via physical wounding can affect plant defense and influence response to subsequent herbivory Here, we focus on the effects of low-severity wildfire on tree defense against attack by bark beetles
- Microsoft Word - fire-insectswhitepaper-dellasala. docx
Recent field studies in western forests have consistently shown that outbreaks actually do little to increase fire severity2,3 In sum, the observed effect of beetle outbreaks on severe fires appears to be negligible
- Fuel Loads and Simulated Fire Behavior in “Old-Stage” Beetle-Infested . . .
Recent bark beetle outbreaks in western North America have led to concerns regarding changes in fuel profiles and associated changes in fire behavior Data are lacking for a range of infestation severities and time since outbreak, especially for relatively arid cover types
- Evolutionary ecology of fire | U. S. Geological Survey - USGS. gov
Many diverse traits provide a fitness benefit following fires, and these adaptive traits vary with the fire regime Some of these traits enhance fire survival, while others promote recruitment in the postfire environment
- A review of thermal exposure and fire spread mechanisms in large . . .
Due to socio-economic and climatic changes around the world, large outdoor fires in the built environment have become one of the global issues that threaten billions of people The devastating effects of them are indicative of weaknesses in existing building codes and standard testing methodologies
