This research based publication has been published to analyze the various inventory techniques, their uses and conservation status on Medicinal and Aromatic Plants (MAPs). This publication is not only the research oriented paper but also the manual of overall plant resources, especially on MAPs. Students, teachers, naturalists, researchers and even the policy makers can use this publication to solve the problems related to sustainability of medicinal plants conservation and management. This publication will be very much fruitful to those who are planning to conduct their research project or intend to acquire skills and knowledge on MAPs. Quantification of MAPs such as frequency, relative frequency, abundance, density, relative density and yield has been calculated which can be used for the sustainability. Simpson''s index and Shannon Weaver function has been calculated using the formulae (see in the data analysis part) . Rapid Vulnerability Assessment, casual factors of depletion and SWOT analysis has been systematically analyzed for identifying the status of MAPs in natural habitat.
