Phytosociological Assessment of Vegetation at Indira Gandhi National Open University (IGNOU) Campus at New Delhi.

Abstract

The paper aims to investigate the phytosociological attributesthe vegetation of the managed campus area of Indira Gandhi National Open University (IGNOU)situated atNew DelhiinIndia. The purpose of the studywas tounderstand thediversity pattern of vegetationfor its characterization. The vegetation sampling and data analysis were undertaken by adopting universally standard procedures. Findings ofthe study demonstrated that the study area had a totalof116 species of plants which belongedto 28 different families. Out of which 55 speciesof trees, 29 species of shrubs and32 species of herbs weretaken onrecord.The most common plant species based on importance value in tree, shrub and herb layers were found to beAzadirachta indica(IVI-66.87), Matricaria chamomilla(RVI-51.89) and Cynodon dactylon(RVI-68.87),respectively. Amongstfamilies,Fabaceaewas found tobe the most dominant. Results reflect dominanceof higher trees over ground floras. This study provides baseline informationfor future studieson the managed and natural forest patches exitingin the campus, and suggeststhat suitable conservation and managementof biodiversitycanimprove the natural floral and faunal value ofinstitutionalcampus.
