Wildfires can change a landscape rapidly. Soil erosion can increase dramatically after wildfire. This erosion can remove the topsoil and form rills and gullies that channelize water [1]. Once the process of erosion starts and water becomes channelized, it can be difficult to reverse. However, many ecosystems in Utah have evolved with fire and have the capacity to regrow, recover, and re-stabilize soils after wildfire. When that is not possible, active soil stabilization, seeding, and replanting may be appropriate [2].
