How does topography affect wildfires
WebHigh-severity fires burn with high heat, climb into and remove the tree canopy, and can scorch the soil and tree roots. At a large scale, high-severity fires can be incredibly damaging to wildlife and the ecosystem. Mosaic fires are a mix of mostly low-intensity fire with patches of high- and moderate-severity fire and some unburned forest. WebTOPOGRAPHY The relief features or surface configuration of an area. Topography’s influence on fire behavior is more predictable than the other components in the fire …
