Descripción
In this study, we present a strategy of restoring genetic diversity for conservation of Abies koreana, an endemic species vulnerable to climate change, and especially a species recovery strategy for small populations with high threat of extinction. Species recovery strategy is a restoration method that maintains population vitality and resilience by utilizing genetically appropriate materials to adapt well to future environmental conditions. Korean fir (Abies koreana E.H.Wilson), which is a Korean endemic species that has been designated as an endangered species by the International Union for Conservation of Nature. There are three large and six small populations with a relatively large and small number of individuals, respectively. According to the genetic analysis of the large-scale population of A. koreana, the genetic diversity of each group is relatively high and remains stable to date. According to the spatial genetic structure analysis for selecting the restoration materials to avoid inbreeding depression, it is appropriate to select Mt. Jirisan population at intervals of about 30 meters between individuals and Mt. Hallasan group of about 15 meters. A total of six small populations of A. koreana in Korea, have a distribution area of less than 1ha. Small population with a restrict distribution has high risk of extinction due to low number of individuals, low genetic diversity and low seedlings in the population, so it is necessary to restocking method. Selecting the restoration materials for the small population needs to consider the genetic diversity and uniqueness of the natural population while enhancing their adaptability and resilience against environmental change. In order to restore genetic diversity of small populations to maintain the resilience, an approach is needed to evaluate the genetic similarity between the populations in Korea and to introduce appropriate restoration materials considering genetic diversity.
