Porpidia ochrolemma

Unknown

Overview

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

Porpidia ochrolemma faces significant threats from air pollution and acid deposition, which alter the chemical composition of its rock substrates and disrupt the delicate pH balance required for lichen survival. Climate change poses additional risks through altered precipitation patterns and temperature fluctuations that affect the species' ability to photosynthesize and reproduce. The lichen's restricted distribution makes it particularly vulnerable to localized environmental changes and human disturbances in its montane habitats.

Threat summary

Habitat

This crustose lichen species inhabits exposed siliceous rocks and cliff faces in montane and subalpine environments, typically growing on acidic substrates at elevations between 1000-2000 meters. It requires specific microclimate conditions with adequate moisture and clean air quality to maintain its symbiotic relationship between fungal and algal components.
