Target 8 of the Global Strategy for Plant Conservation calls for 'at least 75 per cent of threatened plant species in ex situ collections, preferably in the country of origin, and at least 20 per cent available for recovery and restoration programmes by 2020'.Botanic gardens make a significant contribution to ex situ conservation of wild species with more than a third of plant species represented in botanic gardens collections. These collections are a combination of living collection and seed banked material. Seed banking can provide an efficient form of conservation for wild plant genetic *** from Botanic Gardens Conservation International's(BGCI) databases(GardenSearch,PlantSearch, ThreatSearch and GlobalTreeSearch) has been analysed as well as survey data to report on global, regional and national seed banking *** from BGCI's databases indicates that there are at least 350 seed banking botanic gardens in 74 countries. In total 56,987 taxa have been banked including more than 9000 taxa that are threatened with extinction. 6881 tree species are stored in ex situ seed bank collections. More than half(3562) of these tree species are single country endemics and represent species from more than 166 *** study suggests that institutions are increasingly conserving plant species via seed *** the majority of species in collections that have a conservation assessment are not threatened with extinction. This disjunction between species that are threatened and those conserved in seed banks needs to be addressed. Data from BGCI's databases can be used to enable prioritisation of threatened plant species for collection and conservation in seed banks. Further recommendations for botanic gardens involved in seed conservation are presented.

Botanic Garden Collections—An Under-Utilised Resource

Botanic gardens and arboreta around the world are repositories of diverse collections of useful plants in their gardens and seed banks. However, the crop and forestry communities often overlook these collections, and so they are an underutilised resource. For example, in analysis of the ex situ conservation status of 6,941 socio-economically important plant taxa using data from forestry and crop collections, but omitted collections in botanic gardens and arboreta. In this paper, we compared the socio-economically important taxa identified by Khoury et al. from GRIN-Global World Economic Plants (WEP) with data on living and seed collections held in botanic garden and arboreta, as recorded in BGCI’s global PlantSearch and ThreatSearch datasets. This analysis produced an assessment of the proportion of these taxa that are found in botanic gardens and arboreta, the number of gardens or arboreta they are found in and what potential they have to contribute to research, conservation and sustainable use. We also compared the species conservation comprehensiveness assessments carried out by Khoury et al. with the threatened status of those species, according to the IUCN Red List and other threat assessment methodologies in order to ascertain whether threatened, useful species are well-conserved in botanic gardens. At least 6017 of the 6941 socio-economically important WEP taxa (86.7%) were currently found in the living and seed collections of botanic gardens and arboreta with 1456 taxa (21%) held in >40 collections. Khoury et al. suggested that 6748 of the WEP taxa are of either medium or high conservation priority. However, our analysis suggested that just 1153 taxa have been assessed as threatened at a national or international level. We concluded that the botanic garden/arboretum community can contribute significantly to plant conserv
