Abstract

Acacia auriculiformis is endemic plant species to Australia, Papua New Guinea, and Indonesia, which is accepted in India since the early 1940s. It was introduced to degraded and drought-prone Purulia for vegetation restoration and soil conservation. Due to increasing human and livestock population along with unsustainable use of natural resources, soil health is degrading day by day. In case of soil health, the physical, chemical, and biological properties of soil improved by tree species as they add high amount of leaf, root, twig, flowers, and fruits biomass to the soil. However, forestry of A. auriculiformis species becomes harmful for soil health and environment in the study area. Through detailed field survey and measurements of soil properties, the authors have detected this species is harmful for the soil health through reduction of soil moisture, soil fertility, atmospheric moisture, and undergrowth. This study highlights the impact of A. auriculiformis afforestation on the physical, chemical, and biological properties of the soil in Purulia district.
