According to recent estimates, one-fifth of all plant species are thought to be in danger of going extinct in the wild. Reintroduction is one option for protecting many endangered plant species, and it shows great potential, especially when carefully managed by adhering to rules and when monitored over an extended period of time. We examine the Best Reintroduction Practice Guidelines from the Center for Plant Conservation and emphasise key elements for organizing plant reintroductions. Practitioners should examine alternate conservation measures, recognize dangers, and make sure that these threats are not present at any recipient sites before trying reintroductions. Target species and recipient site characteristics must be planned for along with logistical and legal considerations. Establishment and population expansion will be influenced by the careful selection of the founder population's genetic make-up, recipient site, and founder population size. Practitioners should experiment with reintroductions as often as feasible and report their findings. Planning a suitable monitoring technique for the taxon must take present and future demands into account because long-term monitoring over decades will be necessary to document if populations are sustainable. The science and practise of plant reintroduction can be advanced by botanical gardens.
