Over the last few decades botanic gardens worldwide have been encouraged to adopt complementary measures for the conservation of plant species from their own
regions, combining in situ conservation efforts with ex situ methods, both in cultivation and in storage. This integrated approach is particularly important for botanic gardens in the tropics, which face the challenge of conserving a highly diverse and often threatened flora. We gathered information on the occurrence of threatened species in the natural vegetation reserves of Brazilian botanic gardens.The occurrence of threatened species in the reserves of botanic gardens highlights the scientific value of these areas, as well as their biological, social and cultural importance for
conservation. The results may be used to inform the planning of integrated conservation strategies for threatened species.
