Justification of Red List category
Ciconia stormi is native to the swamp and plains-level forests of the Greater Sundas, where it occurs at a very low density and nowhere is numerous. Over the past three generations (31 years: 1992–2023), it is suspected of having declined rapidly (40–60%) in response to industrial removal of its habitat for agro-industry plantations, particularly oil-palm and rubber. Its global population size is uncertain, but probably numbers 300–1,750 mature individuals; with ongoing habitat loss compounded by forest fires which may increase with frequency in response to climate change, this species is considered to be a high risk of extinction in the near-term. Accordingly, it is listed as Endangered.
