Kurzfassung auf Englisch: The state of Rajasthan is situated between 23º3’ and 30º12’ N latitude and 69º30’ and 78º17’ E longitude . The total land area of the state is about 3,24,239 km² , out of which about 1,98,100 km² is arid and the rest semi arid. The physical features are characterized mainly by the Aravallis and to the some extent by the vindhyan formation, and the Deccan trap. A major portion of western Rajasthan has desert soils and sandy plains. Sand dunes occupy a greater
part of western Rajasthan ( 1,20, 983 km²). The soils of the desert plains are loamy sand to loam and the eastern part has alluvial soil which supports good forests and agricultural crop. Occurrence of saline soils with pH up to 9.0 is a common feature in the sandy areas of Rajasthan. The average annual rainfall in the state is 525-675 mm, and the annual precipitation in different tracts of Rajasthan varies from 13 mm to 1766 mm. Out of the total area , forests cover only about 37,638 km² and are rich in biodiversity. Rajasthan is rich in
biodiversity which has a great economic value. Characterization of different plant species of economic value was undertaken. (Table 1-6).
