The effects of fire on soil and water

Figure 1—soil-water repellency as altered by fire: (a) before fire, hydrophobic substances accumulate in the litter layer and mineral soil immediately beneath (b) fire burns the vegetation and litter layer, causing hydrophobic substances to move downward along temperature gradients (c) after fire, a water-repellent layer is present below and parallel to the soil surface on the burned area (debano 1981. Ecosystems: effects of fire on soil and water wildland fire in ecosystems: effects of fire on soil and water, is divided into three major parts (a, b, c) and an introductory chapter that provides discussions of fire regimes, fire severity and intensity, and fire. Keywords: ecosystem, fire effects, fire regime, fire severity, soil, water, watersheds, rehabilitation, soil properties, hydrology, hydrologic cycle, soil chemistry, soil biology, fire effects models the larger bold check-mark boxes indicate the volumes in “the rainbow series” currently published. Environmental effects prescribed burning has direct and indirect effects on the environment proper use of prescribed fire, and evaluation of the benefits and costs of a burn require knowledge of how fire affects vegetation, wildlife, soil, water, and air and in turn how these impact humans especially in population centers burning techniques and timing of burns can be varied to alter fire effects.

After the fire: indirect effects on the forest soil fire's most significant indirect effects on soil are caused by the alteration of standing vegetation and the consumption of organic matter within and beneath the forest floor (debano et al 1998, neary et al 1999. Despite the pronounced effect of fire on soil hydrological systems, information on the direct effect of fire on soil water retention characteristics is limited and contradictory. Quantify the effects of patch burning and grazing on wind erosion, suredpost-fire winderosion (zobecket al,1989whicker soil water content, and soiltemperature insand sagebrush( artemisia et al, 2002.

Fire severity describes the effects of fire on different components of the ecosystem, including its physical, chemical and biological properties disturbance of these properties can affect soil nutrients, cause soil erosion, or alter the water-retention capacity of the soil. Despite the pronounced effect of fire on soil hydrological systems, information on the direct effect of fire on soil water retention characteristics is limited and contradictory to increase. Despite the pronounced effect of fire on flooding and erosion processes and the role of water retention capacity in post-fire plant regeneration, understanding of the direct effect of fire on soil water retention characteristics remains limited and existing information is in many cases contradictory.

Environmental effects prescribed burning has direct and indirect effects on the environment proper use of prescribed fire, and evaluation of the benefits and costs of a burn require knowledge of how fire affects vegetation, wildlife, soil, water, and air and in turn how these impact humans especially in population centers. The effects are chiefly a result of burn severity, which consists of peak temperatures and duration of the fire climate, vegetation, and topography of the burnt area control the resilience of the soil system some fire-induced changes can even be permanent.

Effects of fire on soil physical properties fire may alter several physical soil properties, such as soil structure, texture, porosity, wetability, infiltration rates, and water holding capacity the extent of fire effects on these soil physical properties depends on fire intensity, fire severity, and fire frequency. Chapter topics include the soil resource, soil physical properties and fire, soil chemistry effects, soil biology responses, the hydrologic cycle and water resources, water quality, aquatic biology, fire effects on wetland and riparian systems, fire effects models, and watershed rehabilitation.

  • Potential effects of fire on soil physical properties intense burns may have detrimental effects on soil physical properties by consuming soil organic matter since soil organic matter holds sand, silt, and clay particles into aggregates, a loss of soil organic matter results in a loss of soil structure.
  • This state-of-knowledge review about the effects of fire on soils and water can assist land and fire managers with information on the physical, chemical, and biological effects of fire needed to successfully conduct ecosystem management, and effectively inform others about the role and impacts of wildland fire.

By consuming organic matter, fire influences soil temperatures, nutrient availability, and the flow of air and water through and over soil, which collectively influence forest productivity and soil stability.
