Expanding the Distributional and Ecological Understanding of Ophioglossum rubellum Welw. Ex A.Braun: A New Record from Semi-Arid Menal Forest of Rajasthan

Abstract

This study reports the first documented occurrence of Ophioglossum rubellum Welw. ex A. Braun in the Menal Forest of Rajasthan, a region characterized by its semi-arid climate. This finding significantly extends the known geographical range of the species, previously unrecorded in such dry environments. Detailed observations were conducted to document the species’ morphological features, habitat preferences, and ecological traits. The study highlights the remarkable adaptability of O. rubellum, which thrives in the challenging conditions of the Menal Forest. The findings underline the ecological significance of the Menal Forest as a biodiversity hotspot in semi-arid India. This region, though underexplored, hosts unique flora that demonstrates resilience and ecological importance. The observation of O. rubellum emphasizes the critical need for targeted conservation efforts to protect this fragile ecosystem and its diverse species. The study contributes to our understanding of the ecological diversity of semi-arid landscapes and calls for enhanced preservation strategies to safeguard such habitats. By shedding light on this rare occurrence, the research advocates for further exploration and conservation of semi-arid regions, which play a crucial role in supporting global biodiversity.
