Lack of adequate seed supply is a major bottleneck for effective ecosystem restoration in Chile: friendly amendment to Bannister et al. (2018)

Ex situ seed storage underpins global agriculture and food supplies and enables the conservation of thousands of wild species of plants within national and international facilities. As an insurance policy against extinction, ex situ seed conservation is estimated to cost as little as 1% of in situ conservation. The assumptions, costs, risks and scientific challenges associated with ex situ plant conservation depend on the species, the methods employed and the desired storage time. Recent, relatively widespread evidence of less than expected longevity at conventional seed bank temperatures, innovations in the cryopreservation of recalcitrant-seeded species and economic comparators provide compelling evidence that ultra-cold storage should be adopted for the long-term conservation of plants. Policy instruments, such as the Global Strategy for Plant Conservation (2011-2020), should respond to the evidence base and promote the implementation of cryopreservation for both tropical and temperate plants.

RESUMEN Se presenta un catálogo de las plantas vasculares que crecen en Chile. Está organizado por divisiones, Pteridophyta (Lycopodiopsida y Polypodiopsida), Pinophyta (Gnetopsida y Pinopsida) y Magnoliophyta (Liliopsida y Magnoliopsida), y dentro de cada grupo, las jerarquías taxonómicas (Familia, Género, Especies y taxones infraespecíficos) están ordenados alfabéticamente. Se incluye además un índice alfabético de géneros con indicación de la familia y grupo a que pertenecen. De acuerdo a este catálogo la flora de las plantas vasculares que crecen en Chile, comprende 186 familias, 1121 géneros y 5471 especies, de éstas, 4655 corresponden a especies nativas, de las cuales 2145 son endémicas de Chile y 816 las especies introducidas.
