Abstract: Invasive species are those that occur outside their natural range, spread rapidly and cause harm to other species, communities or entire ecosystem and to human well-being. Soil samples were collected from Mangoli forest which is highly infested/ invaded area with Eupatorium and a comparatively lest invaded area along with the forest in Nainital district, Uttarakhand. Soil were drawn from different depths viz.0-10, 11-30, 31-60 cm. Physiochemical analysis comprises soil texture (Sand 27.7%, Silt 23.36% and Clay 62.86%), Soil moisture (5.82%), Water holding capacity (54.8%), Bulk density (1.47 g cm-3), porosity (47.87%). A comparative study shows the Total percentage of the Chemical/Nutrient values were high in highly invaded area as compared to the least invaded forest site Ph (7.20-6.70), C (1.37-0.97 %), N (0.28-0.25Kg/h), P (0.0098-0.0078 %), K (0.0109-0.0094 %).
Key words: Invasive species, Eupatorium conizoides, Shorea robusta, soil physic-chemical properties.
