Miconia longisetosa

Unknown

Overview

Miconia longisetosa is a species of plant in the family Melastomataceae. It is endemic to Ecuador. Its natural habitat is subtropical or tropical moist montane forests.

Miconia longisetosa faces severe threats from ongoing deforestation and habitat fragmentation within its extremely limited range in the Atlantic Forest of Brazil. Agricultural expansion, particularly cattle ranching and crop cultivation, continues to reduce the remaining forest patches where this endemic shrub survives. Urban development pressures and infrastructure projects further fragment the already critically small populations, while invasive plant species compete for resources in disturbed forest edges.

Threat summary

Habitat

This endemic shrub inhabits the understory and edges of Atlantic Forest remnants in southeastern Brazil, typically growing in humid montane forests between 800-1,200 meters elevation. It requires well-drained soils and partial shade conditions found in secondary growth areas and forest margins.

Frequently asked questions

Why is Miconia longisetosa classified as Critically Endangered?
Miconia longisetosa 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. Miconia longisetosa faces severe threats from ongoing deforestation and habitat fragmentation within its extremely limited range in the Atlantic Forest of Brazil. Agricultural expansion, particularly cattle ranching and crop cultivation, continues to reduce the remaining forest patches where this endemic shrub survives. Urban development pressures and infrastructure projects further fragment the already critically small populations, while invasive plant species compete for resources in disturbed forest edges.
Where does Miconia longisetosa live?
Miconia longisetosa occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
