Puya nigrescens

Unknown

Overview

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

Puya nigrescens faces severe threats from agricultural expansion and livestock grazing in its restricted Andean range. Mining activities and infrastructure development further fragment its already limited habitat, while climate change alters the specific temperature and precipitation conditions this high-altitude bromeliad requires. The species' extremely small population size makes it particularly vulnerable to stochastic events and genetic bottlenecks.

Threat summary

Habitat

Puya nigrescens inhabits high-altitude Andean slopes and rocky outcrops between 3,000-4,000 meters elevation. This terrestrial bromeliad grows in specialized montane ecosystems with specific moisture and temperature regimes typical of cloud forest transitions and páramo grasslands.

Frequently asked questions

Why is Puya nigrescens classified as Critically Endangered?
Puya nigrescens 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. Puya nigrescens faces severe threats from agricultural expansion and livestock grazing in its restricted Andean range. Mining activities and infrastructure development further fragment its already limited habitat, while climate change alters the specific temperature and precipitation conditions this high-altitude bromeliad requires. The species' extremely small population size makes it particularly vulnerable to stochastic events and genetic bottlenecks.
Where does Puya nigrescens live?
Puya nigrescens occurs in Peru. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Puya nigrescens?
The main threats to Puya nigrescens are 3.2, 7.1, ai-1, and ai-2. The full IUCN-classified threat record for this species is detailed on the species page.
