Nevertheless, the results of Dr. Lin’s team did not have significantly increased thermophilic values. Only a few mountain summits showed a similar effect, while a summit showed negative values. However, plant biodiversity decreased during the past decade, and it was pretty different from the studies from Europe. It might be due to the water balance in the alpine summits. Therefore, Dr. Lin’s team integrated statistically downscaling climate data derived from European Centre for Medium-Range Weather Forecasts (ECWMF) and vegetation data to calculate the moist-philic index and determine if the vegetation responses were affected by water. The results revealed that some summits significantly decreased moist-philic values, implying that the alpine summit habitats would encounter water deficiency.
Through their long-term monitoring and analyses, we could find the climate changes effects on high mountains and should take further actions to protect and conserve our alpine plants. The ratio of endemic species on these mountain summits is approximately 50%! Most of the plants have been limited to isolated and small sites in Taiwan. Their studies can also support the conservation policy, especially the rare and endemic species in the alpine summit habitats.
