Rustia bilsana

Unknown

Overview

Rustia bilsana is a species of plant in the family Rubiaceae. It is endemic to Ecuador.

Rustia bilsana faces severe threats from habitat destruction due to agricultural expansion and urban development within its extremely limited range. The species' restricted distribution makes it particularly vulnerable to localized environmental changes and human activities. Deforestation and land conversion for farming have significantly reduced available habitat, while the small population size increases extinction risk from stochastic events.

Threat summary

Habitat

Rustia bilsana inhabits tropical moist forests and woodland areas at specific elevational ranges. The species requires intact forest canopy and is associated with particular microhabitat conditions that are sensitive to environmental disturbance.

Why is Rustia bilsana classified as Critically Endangered?
Rustia bilsana 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. Rustia bilsana faces severe threats from habitat destruction due to agricultural expansion and urban development within its extremely limited range. The species' restricted distribution makes it particularly vulnerable to localized environmental changes and human activities. Deforestation and land conversion for farming have significantly reduced available habitat, while the small population size increases extinction risk from stochastic events.
Where does Rustia bilsana live?
Rustia bilsana occurs in Ecuador. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
