Dendroseris litoralis

Unknown

Overview

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

Dendroseris litoralis faces severe threats from invasive plant species that outcompete this endemic tree for resources and space on Juan Fernández Islands. Habitat degradation from introduced herbivores, particularly goats and rabbits, has severely impacted the coastal forest ecosystems where this species naturally occurs. The extremely small population size makes the species highly vulnerable to stochastic events and genetic bottlenecks, while climate change poses additional risks to its specialized island habitat.

Threat summary

Habitat

Dendroseris litoralis is endemic to the Juan Fernández Islands off the coast of Chile, where it inhabits coastal forests and rocky slopes at low to moderate elevations. This tree species grows in the unique temperate oceanic climate of these remote volcanic islands, typically found in areas with high humidity and frequent fog.

Frequently asked questions

Why is Dendroseris litoralis classified as Critically Endangered?
Dendroseris litoralis 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 litoralis faces severe threats from invasive plant species that outcompete this endemic tree for resources and space on Juan Fernández Islands. Habitat degradation from introduced herbivores, particularly goats and rabbits, has severely impacted the coastal forest ecosystems where this species naturally occurs. The extremely small population size makes the species highly vulnerable to stochastic events and genetic bottlenecks, while climate change poses additional risks to its specialized island habitat.
Where does Dendroseris litoralis live?
Dendroseris litoralis 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 litoralis?
The main threats to Dendroseris litoralis 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.
