Abstract: The Parvati Aranga wildlife sanctuary and adjoining Tikri reserve forest in north-eastern Terai region of Uttar Pradesh with its varied ecological habitats and occurrence of patchy wetlands in form of ‘River’ and ‘Tals’ sustains a variety of plant communities. The area also harbours a rich diversity of economical and medicinal plant species, mainly confined to the peripheral region of the forest. A large component of the forest is occupied by diverse forest stands and a number of special habitats portray remarkable vegetational diversity. The present communication reveals that the plant community with special habitat especially in protected and reserve forest area may plays a vital role in the future sustenance of the forest vegetation. Rarity and regeneration pattern of the flora is also discussed.
