Demographic census confirms a stable population of the critically-endangered caryophyllid coral Polycyathus chaishanensis (Scleractinia; Caryophyllidae) in the Datan Algal Reef, Taiwan.

ABSTRACT: Polycyathus chaishanensis is a symbiotic caryophyllid coral described from a single population in a tidal pool off Chaishan, Kaohsiung, Taiwan. Due to its rarity, P. chaishanensis was declared a critically-endangered species under the Taiwan Wildlife Protection Act. In May 2017, a P. chaishanensis colony was discovered in the intertidal area of the Datan Algal Reef, Taoyuan, Taiwan. To determine whether this is a stable population in the algal reef, a demographic census-including data on occurrence, distribution, and colony size-was carried out in the algal reef in southern Taoyuan. Intertidal censuses and sediment collections were conducted at five different sections-Baiyu, Datan G1, Datan G2, Yongxing, and Yongan algal reefs-during the monthly spring low tide from July 2018 to January 20
