Overview

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

Slender Dogtooth Moss faces severe threats from habitat degradation due to atmospheric pollution and acid deposition, which alter the chemical composition of its specialized rock substrates. Climate change poses additional risks through altered precipitation patterns and temperature fluctuations that affect the delicate moisture balance required for this bryophyte's survival. Urban development and quarrying activities in its limited range further fragment and destroy suitable rocky habitats.

Threat summary

Habitat

Slender Dogtooth Moss grows exclusively on acidic rock surfaces, particularly sandstone and quartzite outcrops in montane and subalpine environments. It requires specific microhabitat conditions with consistent moisture levels and minimal direct sunlight, typically found in crevices and sheltered rock faces between 800-2000 meters elevation.
