| Popis: | We argue that botanic gardens, as plant conservation focused institutions, have been tested in temperate regions that possess a relatively robust conservation infrastructure and a relatively low number of threatened species. The ability of the Brazilian botanic gardens to support plant conservation is especially challenging, given their small number relative to Brazil’s plant diversity and the increasing rate of habitat loss and plant endangerment. This study, the first for Brazil, assesses the conservation capacity of Brazilian botanic gardens. An assessment is made of the status of conservation facilities in Brazilian botanic gardens and the conservation status of their plant collections.This was based on a survey sent to thirty-six Brazilian botanic gardens in 2011– 2013 using information from the 2008 Brazilian Red List, and seven state conservation lists. The results identified a small percentage of threatened species (n =102/21 per cent) in ex situ collections of 22 botanic gardens and less than 10 per cent representation for each state red list. An assessment based on the updated Brazilian Red List (2014) showed that 425 threatened species were maintained in living collections of 18 botanic gardens. Despite the extensive size of some collections, the proportion of threatened species in the collections was found to be very low. Improvement in infrastructure, technical capacity, including horticultural skills, and development of policies and protocols will benecessary to increase the effectiveness of the collections for conservation aims. |
