Zygia steyermarkii

Declining

Overview

Zygia steyermarkii is a species of flowering plant in the family Fabaceae. It can only be found in Ecuador.

Zygia steyermarkii faces severe threats from ongoing deforestation and agricultural expansion throughout its limited range in Central American cloud forests. The species' restricted distribution makes it particularly vulnerable to habitat fragmentation, as remaining forest patches become increasingly isolated. Climate change poses an additional threat by altering the moisture regimes essential for cloud forest ecosystems where this leguminous tree depends on specific atmospheric conditions.

Threat summary

Habitat

Zygia steyermarkii inhabits montane cloud forests at elevations between 1,200-2,000 meters, where it depends on the persistent moisture and fog characteristic of these ecosystems. The species typically grows in primary and secondary cloud forest formations with high humidity and relatively stable temperatures year-round.

Frequently asked questions

Why is Zygia steyermarkii classified as Critically Endangered?
Zygia steyermarkii is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Zygia steyermarkii faces severe threats from ongoing deforestation and agricultural expansion throughout its limited range in Central American cloud forests. The species' restricted distribution makes it particularly vulnerable to habitat fragmentation, as remaining forest patches become increasingly isolated. Climate change poses an additional threat by altering the moisture regimes essential for cloud forest ecosystems where this leguminous tree depends on specific atmospheric conditions.
Where does Zygia steyermarkii live?
Zygia steyermarkii occurs in Ecuador. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
