Abstract

Inventorization and monitoring of phyto-biodiversity is essential for its sustainable use and management. In the present study, we assessed the phyto-diversity of Bihar’s Kaimur district. Total species reported from the area were 190 species (155 genera and 56 families) including 48 families of dicotyledons, 5 of monocotyledons and 3 of pteridophytes. The largest two families of the area were Papilionaceae (18 species) and Poaceae (17 species). Based on habit, 99 trees 23 shrub, 15 vine and 53 herb species were reported. Various diversity indices viz. Shannon-Wiener Index, Concentration of dominance, Species Richness Index and Evenness were calculated for different layers. This study revealed that the Majaonda Barchiada site is the most diverse in the region, followed by Konda Bajraco, Rondi and Chakarghata Nadi. The results of the study will be very helpful for different target groups for conserving and managing and phyto-diversity of areas.

Conclusion

In the present work a total of 190 species (56 families, 155 genera) were reported from the forest sites of Kaimur district. It includes 48 Dicotyledons families (129 genera, 165 species), 5 monocotyledons families (23 genera, 25 species) and 3 Pteridophyte families (3 genera, 3 species). Largest family reported from the area is Poaceae (17 genera, 17 species) followed by Papilionaceae (12 genera, 18 species), Rubiaceae (11 genera, 12 species), Mimosaceae (6 genera, 10 species), Asteraceae (9 genera, 9 species), Moraceae (4 genera, 9 species), Caesalpiniaceae (4 genera, 8 species), Combretaceae (3 genera, 8 species) etc. Largest genus is Ficus (6 species) followed by Terminalia (5 species), Albizia (3 species), Desmodium (3 species) etc. On the basis of habit, there are 99 tree, 23 shrub, 15 climber and 53 herb species in the area. Important native tree species of the district are Shorea robusta, Madhuca longifolia var. latifolia, Buchanania lanzan, Terminalia bellirica, Terminalia alata, Butea monosperma, Lagerstroemia parviflora, Mytragyna parvifolia, Adina cordifolia, Albizia lebbeck, Anogeissus latifolia, Dalbergia lanceolaria etc. The presence of Lantana camara var. aculeata was observed in the district. It is expected that species may pose threat to natural vegetation in the future. Therefore, suitable management strategies should be adopted to check the invasion of invasive species. The study will be extremely useful for the preparation of future working plan of the forest division and plant diversity related assessment studies.
