Cheng Ken Yu, the moss and bryophyta collection manager at Dr. Cecilia Koo Botanic Conservation Center, observes moss on a rock in Jin Shui forest, in Pingtung, Taiwan, September 10, 2020. Yu said some of the plants they collect may have properties people can use, "Then we'll have these species that we can use. Or perhaps one day when a certain habitat needs this specific species, we can provide it." REUTERS/Ann Wang SEARCH "WANG RARE PLANTS" FOR THIS STORY. SEARCH "WIDER IMAGE" FOR ALL STORIES
