The paper aims to investigate the phytosociological attributes the vegetation of the managed campus area of Indira Gandhi National Open University (IGNOU) situated at New Delhi in India. The purpose of the study was to understand the diversity pattern of vegetation for its characterization. The vegetation sampling and data analysis were undertaken by adopting universally standard procedures. The findings of the study demonstrated that the study area had a total of 116 species of plants which belonged to 28 different families. Out of which 55 species of trees, 29 species of shrubs and 32 species of herbs were taken on record. The most common plant species based on importance value in tree, shrub and herb layers were found to be Azadiracta indica (IVI-66.87), Matricaria chamomilla (RVI-51.89) and Cynodon dactylon (RVI- 106.11), respectively. Amongst families, Fabaceae was found to be the most dominant. Results reflect dominance of higher trees over ground floras. This study provides baseline information for future studies on the managed and natural forest patches exiting in the campus, and suggests that suitable conservation and management of biodiversity can improve the natural floral and faunal value of institutional campus.
