Overview

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

Grootbladig puntmos faces severe decline due to habitat degradation from agricultural intensification and drainage of wetland areas. Eutrophication from agricultural runoff alters the nutrient-poor conditions this moss requires, while climate change threatens the cool, moist environments essential for its survival. Urban development and infrastructure projects continue to fragment and destroy remaining suitable habitats.
