Abstract
The interaction between biodiversity and the physical environment is the foundation of sustainable development. The world's forests cover more than 4 billion hectares, or 31% of the total land area, or 0.6 hectares per person. Indian tropical forests, which are mostly deciduous, are poorly understood in terms of plant diversity, plant sociology, and quantification systems. Delhi's ridge forests are of great interest for biodiversity management in the city. Plant diversity inventories form the basis for other forest management research and initiatives. The North Delhi Ridge, also known as the Kamla Nehru Ridge, is located in the current study area of Delhi, India. This is one of the key areas of biodiversity richness in Delhi to assess the plant sociological characteristics of tree species from sample inventories. The study found an average tree density of 322 trees/ha in the northern ridge forest. The forest is home to many rare and endangered plant species such as Acacia catechu, Chlorophytum borivilianum and Marotas philippensis. Plant community dispersal patterns in the Kamla Nehru Ridge are influenced by many factors, including soil type, topography, and climatic conditions. Ridges have multiple microhabitats that support a variety of plant communities, ranging from dry deciduous forests to thorny scrublands.
