Abstract: Xerophytic vegetation represents one of the most remarkable examples of plant adaptation to environmental stress. The arid and semi-arid regions of north-western India, particularly the Churu district of Rajasthan, support a rich diversity of xerophytic flora adapted to extreme temperatures, low precipitation, high evapotranspiration and nutrient-poor sandy soils. The present review examines the diversity, distribution and adaptive mechanisms of xerophytic plants occurring in Churu district and evaluates their ecological significance and conservation status. Churu forms an important part of the Thar Desert ecosystem and hosts numerous drought-resistant species belonging to families such as Fabaceae, Poaceae, Capparaceae, Euphorbiaceae and Zygophyllaceae. These plants exhibit a wide range of morphological, anatomical, physiological and reproductive adaptations that enable survival under severe moisture stress.
The review synthesizes available literature on xerophytic biodiversity in the region and discusses adaptations including reduced leaf area, succulence, thick cuticles, sunken stomata, extensive root systems, osmotic regulation and Crassulacean Acid Metabolism (CAM). The ecological roles of xerophytes in soil stabilization, nutrient cycling, carbon sequestration and livestock support are highlighted. Despite their resilience, these species face threats from overgrazing, habitat degradation, invasive species, urban expansion and climate change. Conservation approaches emphasizing habitat restoration, sustainable grazing management, and community participation and ex situ preservation are discussed. The study underscores the importance of xerophytic vegetation in maintaining ecological stability and supporting rural livelihoods in arid landscapes. Future research should focus on long-term monitoring, climate resilience and the utilization of native xerophytes in ecological restoration programs.
