Poa siphonoglossa

Declining

Overview

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

Poa siphonoglossa faces severe threats from habitat degradation due to overgrazing by livestock and agricultural expansion in its restricted high-altitude range. Climate change poses an additional critical threat, as warming temperatures force this cold-adapted grass species to retreat to increasingly limited suitable habitat at higher elevations. The species' extremely small population size and fragmented distribution make it highly vulnerable to stochastic events and genetic bottlenecks.

Threat summary

Habitat

This critically endangered grass species is endemic to high-altitude alpine meadows and rocky slopes in mountainous regions. It typically grows in specialized microhabitats with specific soil conditions and moisture regimes found only at elevations above 3,000 meters.

Frequently asked questions

Why is Poa siphonoglossa classified as Critically Endangered?
Poa siphonoglossa 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. Poa siphonoglossa faces severe threats from habitat degradation due to overgrazing by livestock and agricultural expansion in its restricted high-altitude range. Climate change poses an additional critical threat, as warming temperatures force this cold-adapted grass species to retreat to increasingly limited suitable habitat at higher elevations. The species' extremely small population size and fragmented distribution make it highly vulnerable to stochastic events and genetic bottlenecks.
Where does Poa siphonoglossa live?
Poa siphonoglossa occurs in United States. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Poa siphonoglossa?
The main threats to Poa siphonoglossa are 5.3, 8.1, ai-1, and ai-2. The full IUCN-classified threat record for this species is detailed on the species page.
