Thalloloma haemographum

Unknown

Overview

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

Thalloloma haemographum faces severe threats from habitat destruction due to deforestation and agricultural expansion in its limited range. The species' extremely restricted distribution makes it particularly vulnerable to localized environmental changes and human disturbance. Climate change poses additional risks through altered precipitation patterns that could affect the specific microhabitat conditions this lichen requires for survival.
