● Seasonally inundated alluvial areas on islets; below 200 m. Chongqing (Banan Qu, Fengdu, Zhongxian).

Plantago fengdouensis is an amphibious plant with a highly restricted distribution, occurring only between 140 and 160 m on the three alluvial islets in Fengdu and Zhongxian counties and Bannan district within the Three Gorges Dam area. The natural habitats were permanently submerged by the water project in Jun 2003. The living plants are conserved at Wuhan Botanical Garden and Beijing Botanical Garden of the Chinese Academy of Sciences and were reintroduced to Fengdu in 2008.
