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 dramatically affects the behavior and spread of wildfire. Because heat rises, the heat energy released through convection and thermal radiation rises up slopes at an increased rate of spread. The angle and orientation of slope are also important, as is the nature and extent of vegetation on a slope.
