Ectomycorrhiza (ECM) is an association of fungi with the roots of higher plants in which both the species are equally benefited and appears to be important for the survival of both parties, and no doubt this association offered extensive benefits in the restoration of forest and ecosystem soil aggregation and stabilization. The most important and vital role of ECM fungi, which is analyzed globally, is that they are best and environment friendly biofertilizers. ECM fungi considered as a biotechnological tool in forest management because their role in reforestation, bioremediation, control of soil pathogen, and restoration of ecosystem is reviewed extensively. ECM fungi not only increase the biomass of edible fruiting bodies but also improve soil structure, nutrient cycle, and also produce phytohormones, which increase the growth and survival of seedlings and enhance the photosynthetic rate of plants and also maintain their tolerance level against environmental stresses in forest nursery. Ectomycorrhizas also reduce fertilization expenses in an environment friendly manner. The importance of ECM fungi and mycorrhizal helper bacteria for the growth enhancement of the economically important trees and significantly important role in restoration of sites degraded by forestry operation.
