039C221E9068C96800E2FF4CFBC4C042.taxon	biology_ecology	Phenology — Flowering and fruiting from July to November. Habitat and distribution — Impatiens baishaensis occurs in forest understories, along canals, shaded moist places, and roadsides at elevation 2100 – 2300 m. Presently, the new species is known only from Hongya and Liangshan counties, Sichuan, China.	en	Ding, Bo, Wang, Jia-Cai, Deng, Hong-Ping, Wang, Chao-Ying (2017): Impatiens baishaensis (Balsaminaceae): a new species from Sichuan, China.

039C221E9068C96800E2FF4CFBC4C042.taxon	conservation	Conservation status — Only five populations are known, with a total of about 1000 individuals; the area of occupancy is less than 10 km 2. We classify the conservation status of Impatiens baishaensis as Vulnerable (VU D 2), based on current information and following the International Union for Conservation of Nature and Natural Resources guidelines (IUCN, 2016). Although the area is under protection as a national nature reserve, habitat disturbance brought about by human activities such as grazing and trampling may have a negative impact on the species.	en	Ding, Bo, Wang, Jia-Cai, Deng, Hong-Ping, Wang, Chao-Ying (2017): Impatiens baishaensis (Balsaminaceae): a new species from Sichuan, China.
