Overview

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

Melvin charr faces severe threats from habitat degradation, invasive species introductions, and climate change impacts on cold-water lake ecosystems. The species' restricted range and specialized habitat requirements make it particularly vulnerable to environmental changes and human activities affecting pristine alpine and subarctic lake systems.

Threat summary

Habitat

Cold, deep oligotrophic lakes in alpine and subarctic regions, typically at high elevations with clear, well-oxygenated waters. The species requires pristine lake ecosystems with specific temperature and water quality conditions characteristic of northern char habitats.
