Dendroseris pruinata

Unknown

Overview

Sonchus pruinatus, synonym Dendroseris pruinata, is a species of flowering plant in the family Asteraceae. It is endemic to the Juan Fernández Islands of Chile. It is threatened by habitat loss.

Dendroseris pruinata faces severe threats from invasive plant species that outcompete native vegetation and alter ecosystem dynamics on Juan Fernández Islands. Habitat degradation from introduced herbivores, particularly goats and rabbits, has severely impacted the endemic flora communities where this species occurs. The extremely limited population size and restricted range make the species highly vulnerable to stochastic events and genetic bottlenecks.

Threat summary

Habitat

This endemic species inhabits the unique temperate rainforest and cloud forest ecosystems of the Juan Fernández Islands, typically found in areas with high humidity and persistent cloud cover. It grows in association with other endemic flora in the archipelago's distinctive fernland and forest communities.

Frequently asked questions

Why is Dendroseris pruinata classified as Critically Endangered?
Dendroseris pruinata 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. Dendroseris pruinata faces severe threats from invasive plant species that outcompete native vegetation and alter ecosystem dynamics on Juan Fernández Islands. Habitat degradation from introduced herbivores, particularly goats and rabbits, has severely impacted the endemic flora communities where this species occurs. The extremely limited population size and restricted range make the species highly vulnerable to stochastic events and genetic bottlenecks.
Where does Dendroseris pruinata live?
Dendroseris pruinata 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 Dendroseris pruinata?
The main threats to Dendroseris pruinata are 2.3, 8.1, ai-1, and ai-2. The full IUCN-classified threat record for this species is detailed on the species page.
