Summary
This summary is machine-generated.Prescribed fire helps manage wildfire risk, but only 6.2% of treated areas in the US encountered a subsequent wildfire between 2003-2023. Western forests showed higher encounter rates than eastern forests.
Area Of Science
- Ecology
- Forestry
- Environmental Management
Background
- Prescribed fire is a key fuel treatment for wildfire risk reduction and ecosystem restoration in the US.
- Increased catastrophic wildfires are driving broader adoption of prescribed fire practices.
- Effective wildfire risk reduction requires treated areas to subsequently encounter wildfire.
Purpose Of The Study
- To quantify the encounter rate between prescribed fire treated areas and subsequent wildfires across the US.
- To analyze how encounter rates vary by region, time interval, treatment area, and prior fire history.
Main Methods
- Utilized geospatially resolved datasets of prescribed fires and wildfires from 2003-2022.
- Calculated encounter rates on US Forest Service lands in the Conterminous US (CONUS).
- Summarized encounter rates across various temporal and spatial factors.
Main Results
- 6.2% of prescribed fire treated area (2003-2022) encountered a subsequent wildfire (2004-2023) on CONUS Forest Service lands.
- Encounter rates were higher in western US forests compared to eastern US forests.
- Encounter rates increased with treatment area in the Southeast and with longer time intervals between prescribed and subsequent wildfires across CONUS.
Conclusions
- Findings highlight regional variations in prescribed fire-wildfire interactions.
- Results can inform strategies for optimizing prescribed fire use to maximize wildfire risk reduction benefits.
- Understanding encounter rates is crucial for evaluating the effectiveness of prescribed fire in mitigating wildfire impacts.

The z-transform is a powerful mathematical tool used in the analysis of discrete-time signals and systems. It is a crucial tool in the analysis of discrete-time systems, but its convergence is limited to specific values of the complex variable z. This range of values, known as the Region of Convergence (ROC), is fundamental in determining the behavior and stability of a system or signal. The ROC defines the region in the complex plane where the z-transform converges, which can take various...
Burn injuries occur when the skin and underlying tissues are damaged due to exposure to heat, electricity, chemicals, radiation, or friction. They can vary in severity, from minor superficial burns to severe deep burns that can be life-threatening.
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...
Consider an object upon which multiple forces are acting. If the lines of action of each force lie within the same plane, the system can be considered coplanar. The Cartesian vector form can be used to resolve each force into its respective components. For a coplanar system, the system will be in equilibrium if each component of the resultant force equals zero and the resultant force on the system is zero. If the sum of the forces is not equal to zero, then the object will not be in equilibrium...
Hybrid zones are narrow regions where two closely related species interact, mate, and produce hybrids. Relative to either parent species, hybrids may possess distinct phenotypic or genetic differences that impact their survival and reproductive success. The genetic variances introduced by hybridization influence species diversity and speciation processes within the hybrid zone.
Gene flow and natural selection are evolutionary mechanisms that shape the outcome of a hybrid zone. Gene flow...
There are three methods by which heat transfer can take place: conduction, convection, and radiation. Each method has unique and interesting characteristics, but all three have two things in common: they transfer heat solely because of a temperature difference; and the greater the temperature difference, the faster the heat transfer.
In order to solve a problem related to heat transfer, first of all, the situation needs to be examined to determine the type of heat transfer involved. This could...
Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.
The structures that arise from convergent evolution are called analogous structures. They are similar in function even if they are dissimilar in structure. Further, structures can be analogous while...
