Main Article Content


The life form classification and construction of biological spectrum of Chiktan valley of Kargil district in Ladakh region of North West Himalaya has been done after complete enumeration of floristic composition. A total of 79 plant species has been listed and grouped into various life form classes after Raunkiaer (1934). Hemicryptophytes (40.50%) and Therophytes (24.05%) dominated the landscape of this area followed by Chamaephyte (17.72%), Phanerophytes and Geophytes (8.86%). The life form spectrum was the characteristic of desert climate with scanty rainfall and steppe vegetation.  Compared to the normal biological spectrum of Raunkiaer, Phanerophytes showed maximum deviation (-37.14) followed by Hemicryptophytes (+14.50) and Therophyte (+11.50).
