摘要

可持续的栖息地在决定濒危物种的生存和栖息地保护方面发挥着重要作用。保护濒危物种二歧鸢尾。以及它在大安海安国家公园的栖息地,我们从自然种群中收集种子,并在温室中发芽繁殖。2019年,在大安海国家公园的两个研究地点移植了繁殖的二歧I.dichotoma个体。保护易位后,从2020年到2022年进行了年度监测,并测量了与二分子花存活和生长相关的因素(克隆繁殖率[%]、开花率[%],种群密度[个体/m2]、最大叶束长度[高度;cm]、最大叶丛宽度[cm]和蒂长[cm])。根据移植后三年的开花结果期监测结果,总共有82.4%的个体存活下来。在2020年至2022年期间,平均种群密度(个体/m2)从0.36增加到0.42,叶束长度和宽度与2019年的相应数字相比都有所下降(p<0.05)。

Changes of an endangered population of Iris dichotoma after conservation translocation in Taeanhaean National Park, Korea
Sustainable habitats play a significant role in determining the survival and habitat preservation of endangered species. To conserve the endangered species Iris dichotoma Pall. and its habitat in Taeanhaean National Park, we collected seeds from a natural population and germinated and propagated them in a greenhouse. In 2019, the propagated individuals of I. dichotoma were transplanted at two study sites in Taeanhaean National Park. After conservation translocation, annual monitoring was conducted from 2020 to 2022, and factors related to the survival and growth of I. dichotoma (clonal propagation rate [%], the flowering rate [%], the population density [individual/m2], the maximum leaf bundle length [height; cm], the maximum leaf bundle width [cm], and the pedicel length [cm]) were measured. According to the results of the monitoring of the flowering and fruiting periods for three years after transplantation, 82.4% of individuals in total were found to have survived. During 2020 to 2022, the mean population density (individual/m2) increased from 0.36 to 0.42 and the size of the leaf bundle length and the width both decreased compared to the corresponding figures in 2019 (p < 0.05). According to the findings here, the transplanted population of I. dichotoma is considered to have adapted successfully to its new site in Taeanhaean National Park.
