Synopsis The inception of this book goes back to sometimes in 1991, when we visited to Pachmarhi with students to study the flora of these regions. Although, that we are looking the flora of this regions from 1965 and realizing the decline of the flora of this regions gradually. In 1965, Pachmarhi was completely undisturbed and all the spots were full of flora and fauna and climatic conditions at various sites were different from present state of conditions. Every path of the forest track was full of treasures. Gradually and slowly the biodiversity of this regions is declining because of habitat reduction, fragmentation, degradation and replacement. The introduction of exotic species, over-exploitation of biological resources, large scale of deforestation and influx of tourist population has the proximate cause of loss of biodiversity of this regions. Many valuable species of this regions have been disappeared or in verge of extinction. To study the environment impact assessment (EIA) of this region, we had started the work under project Department of Biotechnology [DBT] in 1997. This work is an outcome of the project entitled "Rare, endangered and threatened plants of Pachmarhi hills. An ecological and biotechnological approach for biodiversity conservation. "The project was came in operation in June, 1997 in which three research fellows were collected the data from remote areas of the hills. In this book all the information is incorporated on the basis of their work.
