“…Frequent tropical cyclones are the main disturbance agent preventing these forests from ageing, especially at exposed parts of Mt. Hallasan (Kim et al 2017). Conifers often experience more damage than broadleaves (Yoshida and Noguchi 2009) and damage increases with altitude (Dhôte 2005;Ishizuka et al 1997), which is also supported by the elevational gradient in our tree-age distribution (Table 1).…”

“…With 181 years (1830-2010) our QUMO chronology from a lower elevation (1230 m a.s.l.) site covers the longest period of all species investigated so far at Jeju Island (Kim et al 2017;Seo et al 2019;Zhang et al 2019).

“…ABKO, on the contrary, has very limited possibilities to physiologically adapt to these climate changes as its photosynthetic rate is significantly reduced during drought, especially under full sunlight (Je et al 2018). Furthermore, subalpine ABKO populations are most vulnerable to disturbance by tropical cyclones (Kim et al 2017), which increases the chance for ABKO's complete extinction at Jeju Island (Yun et al 2018). Hence, combining knowledge from various research fields (ecology, physiology, genetics, modelling, growth) to investigate ABKO decline will provide strong support for active conservation of these highly vulnerable populations (Liang et al 2018).…”

Tree growth response to recent warming of two endemic species in Northeast Asia

The impact of climatic change on forest ecosystems has received considerable attention, but our understanding of the modulation of this impact by elevational differences and by species interaction is still limited. Here, we analyse tree-ringbased growth-climate relationships for two dominant tree species along an 800-m elevational gradient on Jeju Island, South Korea. Both species, broadleaf Quercus mongolica (QUMO) and coniferous Abies koreana (ABKO), grow at the southern end of their distributional range and they have adjacent altitudinal ranges. We use static and moving bootstrapped correlation analysis to identify the effect of recent warming on their growth. QUMO is primarily positively influenced by moisture during the previous autumn at its upper elevational distribution. Recent warming, however, has diminished this relationship, while the enhancing impact of warm and dry summer conditions on QUMO growth has increased. These recent shifts in growth-climate relationship suggest an upward migration potential for QUMO due to warming-enhanced growth at higher elevations. ABKO growth, on the contrary, is primarily reduced by high winter and summer temperatures. This negative relationship has become more explicit in recent decades, particularly at lower elevations. At the highest elevation, however, ABKO growth-temperature relationship has consistently become more positive in the most recent decades. In the elevational zone where ABKO and QUMO co-exist, warming plays a primary role in ABKO growth reduction, while QUMO growth increases and thus induces a potential upward migration of QUMO. This combined effect can lead to population decline of ABKO. Our results significantly enhance our understanding of the impact of climate warming on two interacting species and provide information necessary for adaptation strategies to preserve declining ABKO populations.

“…In addition, Korean fir is designated as the Climate-sensitive Biological Indicator Species (CBIS) in Korea (Lee et al 2010). There are studies on the habitat, distribution, and population dynamics of the tree species (Kong and Watts 1993;Kim 1996;Koh et al 1996;Kim and Choo 2000;Kim et al 2007Kim et al , 2016Kim et al , 2017Song 2011;Song et al 2014); the radial growth of the tree species using tree rings being affected by ambient temperature and precipitation of the sites (Kim 1994;Koo et al 2001;Kang et al 2013;Zhang et al 2018); and potential effects of climate to tree growth including droughts Kim 2000, Kim et al 2015a). Currently, the growth dynamics of Korean fir trees as well as the interactions among the micro-climatic factors are not well known at the forest site of the mountain, however.…”

To understand the dynamics of radial growth of trees and micro-climate at a site of Korean fir (Abies koreana Wilson) forest on high-altitude area of Mt. Hallasan National Park, Jeju Island, Korea, high precision dendrometers were installed on the stems of Korean fir trees, and the sensors for measuring micro-climate of the forest at 10 minutes interval were also installed at the forest. Data from the sensors were sent to nodes, collected to a gateway wireless, and transmitted to a data server using mobile phone communication system. By analyzing the radial growth data for the trees during the growing season in 2016, we can estimate that the radial growth of Korean fir trees initiated in late April to early May and ceased in late August to early September, which indicates that period for the radial growth was about 4 months in 2016. It is interesting to observe that the daily ambient temperature and the daily soil temperature at the depth of 20 cm coincided with the values of about 10°C when the radial growth of the trees initiated in 2016. When the radial growth ceased, the values of the ambient temperature went down below about 15°C and 16°C, respectively. While the ambient temperature and the soil temperature are evaluated to be the good indicators for the initiation and the cessation of radial growth, it becomes clear that radii of tree stems showed diurnal growth patterns affected by diurnal change of ambient temperature. In addition, the wetting and drying of the surface of the tree stems affected by precipitation became the additional factors that affect the expansion and shrinkage of the tree stems at the forest site. While it is interesting to note that the interrelationships among the micro-climatic factors at the forest site were well explained through this study, it should be recognized that the precision monitoring made possible with the application of high resolution sensors in the measurement of the radial increment combined with the observation of 10 minutes interval with aids of information and communication technology in the ecosystem observation.
