Q.What is the role of national gardens in conserving biodiversity - discuss

Step 1. Start from the base function. Botanical/national gardens are centres for collection of plants in their various stages of living - they maintain a wide range of species drawn from across regions, which is the foundation of any conservation effort, since nothing can be conserved that has not first been collected and maintained.

Step 2. Name the conservation-specific roles. The chapter lists: acting as a conservation centre for diversity and for rare and endangered species (e.g. the National Botanical Garden Lucknow's germplasm collection and ex-situ conservation programme); supplying taxonomic material for botanical research so species can be studied, documented and monitored; and offering an annual list of available species together with a free exchange of seeds, letting the same genetic material be propagated and safeguarded at multiple institutions rather than surviving in only one place. …
