Plant diversity is currently being lost at an unprecedented rate, resulting in an associated decrease in ecosystem services. About a third of the world's vascular plant species facing the threat of extinction due to a variety of devastating activities, including, over-harvesting and over exploitation, destructive agricultural and forestry practices, urbanization, environmental pollution, land-use changes, exotic invasive species, global climate change, and more. We therefore need to increase our efforts to develop integrative conservation approaches for plant species conservation. Botanical gardens devote their resources to the study and conservation of plants, as well as making the world's plant species diversity known to the public. These gardens also play a central role in meeting human needs and providing well-being. In this minireview, a framework for the integrated missions of botanical gardens, including scientific research, in/ex situ conservation, plant resource utilization, and citizen science are catalogued.

"A botanical garden or botanic garden is a garden dedicated to the collection, cultivation, preservation and display of a wide range of plants labelled with their botanical names".

Objectives and functions of BG:

• To serve as a living repository for plants of the regional and local area.
• To display and exhibit various plant species of conservation concern
• Ex-situ Conservation and Propagation of Medicinal, Threatened and Endemic Plants
• To maintain plant collections for the purpose of display, education, research, conservation
• To communicate the importance of plant diversity to students, researchers and others.
• To propagate selected important species and distribution to targeted communities.
• To address the present and future needs for training, education, institution building and research
• To publicize and promote environmental education
• To serve as a safe abode of threatened flora
• To house the germplasm collection of selected cultivated, ornamental and medicinal plants.
• To maintain a herbarium for the benefit of student community and to promote research.
