The Global Strategy for Plant Conservation (GSPC) was adopted by the Convention on Biological Diversity in 2010. The strategy provides the overall framework for plant conservation at the global and national levels and consists of 16 targets. Targets 7 and 8 call for at least 75% of known threatened plant species conserved in- and ex-situ and at least 20% available for recovery and restoration programs by 2020. Korea National Arboretum makes a significant contribution to the in- and ex-situ conservation of plant species at the national level. A review of progress in the implementation of targets 7 and 8 of the GSPC in Korea based on information provided by reports and database of Korea National Arboretum was conducted. According to the data, 88.1% of threatened plants are conserved in-situ by protected areas in Korea. Also, 91% of threatened plants are conserved ex-situ by seed bank and living collection in Korea National Arboretum. Among them, 15% of plants were reintroduced to putative habitat so far. This data will be very important in the preparation of the GSPC national report that should be submitted by 2020.
