Hornschuchia leptandra

Declining

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Hornschuchia leptandra faces severe pressure from agricultural expansion and cattle ranching across its limited range in Brazil's Atlantic Forest region. Habitat fragmentation has isolated remaining populations, reducing genetic diversity and limiting natural regeneration. Urban development and infrastructure projects continue to encroach on the species' remaining forest patches, while invasive plant species compete for resources in degraded areas.

Threat summary

Habitat

This endemic Brazilian plant species inhabits remnant Atlantic Forest fragments, typically growing in humid montane forests and forest edges at elevations between 800-1,200 meters. It requires well-drained soils and partial shade conditions characteristic of the Atlantic Forest's complex canopy structure.

Frequently asked questions

Why is Hornschuchia leptandra classified as Endangered?
Hornschuchia leptandra is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Hornschuchia leptandra faces severe pressure from agricultural expansion and cattle ranching across its limited range in Brazil's Atlantic Forest region. Habitat fragmentation has isolated remaining populations, reducing genetic diversity and limiting natural regeneration. Urban development and infrastructure projects continue to encroach on the species' remaining forest patches, while invasive plant species compete for resources in degraded areas.
Where does Hornschuchia leptandra live?
Hornschuchia leptandra occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Hornschuchia leptandra?
The main threats to Hornschuchia leptandra are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
