Abstract
With the growing modern civilization, the ever increasing role of plants to human life has placed before us many fold tasks for understanding intimately the world of the plants and their relationships with human being.Demographic analysis of a plant community is the first and foremost basis for study of any piece of vegetation. The floristic studies based on demography data present a complete picture of the vegetation i. e. distribution-pattern and seasonal changes of the plant communities inhabiting a particular area or region. The dependence of man on medicinal plants is next to food for life sustenance. Continuous exploitation of medicinal plants has also been causing extinction of certain species. There is, therefore, need for intensive agricultural studies leading to genetic improvement and cultivation methods for expansion of area under medicinal and aromatic plants.In the present investigation a fact was established by long observations that the vegetation of a region or a locality, in general, follows a certain well-defined distribution pattern. Authors have studied the vegetation of Mainpuri district of Uttar Pradesh. This area is located in tropical zone between 26°53' to 2734' North latitude and 7827' to 7926' East longitude and covers an area of nearly 4343 s. km. The climate of the district is markedly periodic and of semi-arid nature which is characterized by a dry and hot summer, a warm monsoon and a bracing cold winter. The soil of the district is divisible into three types i.e. Matiyar, Bhur and Dumat within this there is a vast area of wasteland known as 'usar' is available, which is not fit for irrigation. Here 66752 hectares of land is usar land therefore the vegetation of this land is scarce and only few restricted plants flourish, therefore, understanding of natural ecosystem is important for their conservation. During the present ecological investigations it was found that the medicinal herbs viz: Adhatoda vasica, Achyrantes aspera, Argemone mexicana. Bacopa monnierri, Centella asiatica, Datura stramonium, Calotropis procera, Euphorbia hirta, Plantago ovata, Solanum xanthocarpum, Trianthema portulacastrum, Tribulus terrestris, Withania somnifera were abundant. Medicinal grasses viz. Cynodon dactylon, Cymbopogon nardus showed the dynamics regeneration process by suckers and rhizomes and medicinal trees like Acacia nilotica, Pongamia pinnata, Syzygium cuminii, Terminalia arjuna, Ficus bonghalensis, were most popular.
