A fuel ladder or ladder fuel is a firefighting term for live or dead vegetation that allows a fire to climb up from the landscape or forest floor into the tree canopy. [ 1 ] [ 2 ] Common ladder fuels include tall grasses , shrubs , and tree branches , both living and dead.

When fire encounters areas of heavy fuel loads (continuous brush, downed vegetation or small trees) it can burn these surface and ladder fuels and may quickly move from a ground fire into a crown fire. Hazardous fuel reduction generally requires the reduction of surface and ladder fuels.

Fuels management builds wildfire resilience by reducing small trees, brush, dead branches, and limbs (called ladder fuels) which makes it less likely that future wildfires will torch an entire landscape.

2020年7月24日 · Ladder fuels are various forms of vegetation that would allow a low-burning fire to vertically climb up from the ground and into a tree canopy. Examples of common ladder fuels include both living and dead vegetation such as shrubs, tall …

We apply these new techniques in the Klamath Mountains of Northern California to predict ladder fuel levels across the study area. Our results demonstrate a new utility of LiDAR data to identify fire hazard and areas in need of fuels reduction. 1. Introduction.

Specifically, it is the lowest height in a stand at which there is a sufficient amount of forest canopy fuel to propagate fire vertically into the canopy. Using this definition, ladder fuels such as lichen, dead branches, and small trees are incorporated.

2020年1月1日 · A ladder fuel is defined as live or dead vegetation or a combination of both that provides vertical and horizontal continuity allowing surface fire to progress into the shrub or tree canopy layer.

Ladder fuels are often targeted in hazardous fuel reduction treatments due to their role in propagating fire from the forest floor to tree crowns. Despite their importance, ladder fuels are difficult to quantify. One common approach is to calculate canopy base height, but this has many potential sources of error.

A ladder fuel is defined as live or dead vegetation or a combination of both that provides vertical and horizontal continuity allowing surface fire to progress into the shrub or tree canopy layer. Common ladder fuels include tall grasses and forbs, shrub foliage, needle drape, woody debris, understory trees, tree branches, lichen, moss, and

This study investigates a new method for quantifying ladder fuel in the field (using photographs with a calibration banner) and remotely (using LiDAR data). We apply these new techniques in the Klamath Mountains of Northern California to predict ladder fuel levels across the study area.
