“…For example, the Instituto Forestal (INFOR) conserves in vitro germplasm of southern beeches ( Nothofagus spp.) and exotic species (Gutiérrez & Koch, 2015), and the germplasm bank of the Servicio Agrícola y Ganadero (SAG) in Magallanes comprises 9,200 species accessions of herbs, shrubs and trees (Niculcar, Latorre, & Vidal, 2015). In contrast, the Instituto de Investigaciones Agropecuarias (INIA), designated as the national curator of Chilean plant genetic resources in the year 1996, undertakes long‐term preservation of orthodox seeds of Chilean native plants in its Seed Base Bank (SBB) and it also provides informative public online access of their collections to the public (León‐Lobos et al, 2003; León‐Lobos, Way, Sandoval, & Pritchard, 2010).…”

Despite the value of Chilean flora, 46% of the species, currently evaluated, are critically endangered or endangered, so ex situ conservation measures are key to their preservation. We analyzed the current state and conservation gaps of the native species preserved in the Seed Base Bank (SBB) of the Instituto de Investigaciones Agropecuarias (INIA), the main curator of Chile's plant genetic resources. Our analysis showed that 3,040 seed accessions of native species are preserved in the SBB, corresponding to 1,256 species, which represents 26.9% of the Chilean flora. The area with the largest number of accessions collected corresponds to the northern and central parts of the country, indicating that there has been a bias in terms of concentrating efforts on the continental regions and ignoring other important geographical regions of Chile, such as those located in the insular territory. A quarter of the threatened plants belonging to the Chilean flora are not currently conserved in the SBB, as they are vascular species without seeds, which cannot be protected in the long term under the traditional conditions of a seed bank. Additional collection and research efforts are required to increase the collection of native species in the SBB, especially threatened and endemic species.
