On the Taiwan island, fog envelops the mountain Chilan all year round. Only three days of the year are clear of fog and moisture left on the trees alone can reach 300 millimeters. This fog stabilizes temperature and humidity in this forest, creating a perfect environment to nurture Asia’s precious primal cypress forest. Prominent female scientist Dr. Yi-ling Lai spends her life in the forest like a genie, reaching through the fog to cypress trees around her, discovering the delicate relationship between fog and the growth of plants that live here.
