Abstract:
This state represented three distinct phytogeographical regions. The transitional belt running along the entire length of the state of Uttarakhand and country of Nepal is called the “Terai’ and ‘Bhabhar’ area and have thick forest cover, swamps and marshes. The Gangetic plain elongates the area from east to west is the most fertile as well as agricultural land. The southern fringe of the Gangetic Plains is demarcated by the Vindhya Hills and Plateau exhibit strong ground and low hills. Most of the central region of the state of Uttar Pradesh is most fertile and utilized for agriculture from the ancient time. The region is devoid of forest, however, mango orchards are quite common and provide suitable habitat for many lichen taxa to colonize. The present investigation is carried out with an aim to document the lichen diversity pattern in mango orchards of Gangetic plain. Three districts of this phytogeographical zone viz. Faizabad, Ambedkar Nagar and Raebareli have been selected to conduct the present study. The identification of the lichen samples collected revealed occurrence of five species as new addition to the lichen flora of the state.
