Grandiphyllum schunkeanum

Unknown

Overview

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

Grandiphyllum schunkeanum faces severe threats from deforestation and habitat conversion in Brazil's Atlantic Forest region. The species' extremely restricted range makes it particularly vulnerable to local disturbances, with mining activities and agricultural expansion fragmenting its remaining habitat. Climate change poses additional pressure through altered precipitation patterns that affect the humid microenvironments this epiphytic orchid requires.

Threat summary

Habitat

This epiphytic orchid inhabits humid montane forests of Brazil's Atlantic Forest biome, growing on tree trunks and branches in cloud forest environments. It requires consistent moisture and filtered light conditions typical of undisturbed primary forest ecosystems at elevations between 800-1,200 meters.

Frequently asked questions

Why is Grandiphyllum schunkeanum classified as Critically Endangered?
Grandiphyllum schunkeanum 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. Grandiphyllum schunkeanum faces severe threats from deforestation and habitat conversion in Brazil's Atlantic Forest region. The species' extremely restricted range makes it particularly vulnerable to local disturbances, with mining activities and agricultural expansion fragmenting its remaining habitat. Climate change poses additional pressure through altered precipitation patterns that affect the humid microenvironments this epiphytic orchid requires.
Where does Grandiphyllum schunkeanum live?
Grandiphyllum schunkeanum occurs in Brazil. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Grandiphyllum schunkeanum?
The main threats to Grandiphyllum schunkeanum are 1.1, 12.1, 2.1, and 5.3. The full IUCN-classified threat record for this species is detailed on the species page.
