This study conducted monitoring of plant species vulnerable or sensitive to Meteorological change—pine trees, azaleas, royal azaleas, sugar maple trees, and Japanese larch trees in Yeongnam region of South Korea for bioclimatological research, and predicted and managed changes in the growth environment of plants in advance, thereby presenting measures to stably preserve plant genetic resources. GPS coordinates of each of the species in each area were marked and changes in their time of blossoming, blossoms falling, leaves unfolding, leaves reddening, and leaves falling were recorded. They were examined once per week from late March 2010 to late November 2011. Indicator plants were analyzed and the time of blossoming tended to be later this year than the previous year and mostly in gravel areas their time of blossoming became later. Their blossoms falling time had a similar pattern to that of their blossoming time. There were no obvious differences in the pattern of leaves unfolding. The time of leaves unfolding of all the investigated species except for pine trees was latest in gravel areas. Sugar maple trees’ blossoms falling time became later in most areas, without regularity, and azaleas, royal azaleas, and Japanese larch trees were observed earliest in Gyeongnam Arboretum. The time of leaves falling became later in most areas. As the temperature became higher in late 2011 relative to 2010, the time of leaves reddening, and leaves falling became later and the growth period of all the species became longer except for pine trees.
