Abstract

This study aims to assess phytosociological study, species diversity and regeneration status across different forest types of north eastern Uttar Pradesh. Field surveys were conducted in representative forest sites to collect data on density, relative as abundance, basal area, Importance Value Index (IVI) and various diversity indices. Mixed forests exhibit high species richness and diversity compared to sal plantation forests. Regeneration patterns suggest that certain species acquire the non- seed regeneration strategy apart from seed germination. A total of 167 plant species representing 136 genera and 63 families were recorded from regional forest. Gamma diversity of regional forest was 3.89. The Shannon’s index was, however, maximum for Mixed forest (3.16 ± 0.19) followed by Sal plantation forest (3.14 ± 0.17) but index was much lower for Teak plantation forest (2.39 ± 0.46). The basal area and IVI was maximum for overstorey strata for all forest types. The regional forest was rich in Papilionaceae (19 species), which contributed maximally to the total number of individuals of <30 cm girth. The Clerodendron infortunatum, Croton oblongifolius, Mallotus philippensis were common ramet producers while Abrus precatorius, Dillenia indica, Erythrina indica and Pterocarpus marsupium were least sprouters. Understanding these ecological dynamics is crucial for effective conservation and management strategies tailored to preserve the unique biodiversity of northeastern Uttar Pradesh’s forests. Further research integrating ecological, socio-economic, and policy dimensions is recommended to sustainably manage these valuable ecosystems.
