The incidence of forest fire decreases the actinomycetes, fungal population and arbuscular mycorrhizal fungi, while increases the bacterial richness. The soil microorganisms are mostly sensitive towards high temperature and mostly affected. ![]() The higher intensity fire results into complete loss of soil organic matter and volatilization of nitrogen, phosphorus and potassium but very high temperature is required for complete burning of Mn, Mg, Cu and other micronutrients. The low intensity fire results in combustion of litter and soil organic matter, increases nutrients availability which supports regeneration of herbs and growth of post fire community. The most significant effects of fire is reported to oak and coniferous forest which takes long time to recover because these species catches high intensity crown fire due to high calorific values. indica, Eupatorium glandulosum, Parthenium hysterophorus, Cassia tora, C. tomentosa which are having commercial and medicinal values gives poor yield after fire incidence and due to frequent fire in these area species of Lantana camara, L. The impact of fire on established trees of Shorea robusta and Tectona grandis has no longer effects and they recovers just on the onset of favourable climatic condition but the status of new recruits are adversely affected. ![]() Forest fire is very common in all the ecosystems and plays an important role in ecosystem dynamics, biodiversity, soil and microbes.
