Acritodon nephophilus

Declining

Overview

Acritodon is a genus of moss in the family Hypnaceae. It is a monotypic genus only containing the species Acritodon nephophilus Acritodon nephophilus is endemic to Mexico, where it is known only from two locations in the Sierra Madre de Oaxaca of Oaxaca state. Its natural habitat is subtropical or tropical moist lowland forests.

It is threatened by habitat loss. Conservation efforts for this species have difficulty protecting local populations due to insufficient attention and legislation regarding preservation of moss species.

Acritodon nephophilus faces severe threats from habitat destruction due to agricultural expansion and urban development within its limited range. The species' restricted distribution makes it particularly vulnerable to localized environmental changes and human encroachment. Mining activities and infrastructure development pose additional pressures on the remaining suitable habitat patches.

Threat summary

Habitat

This species inhabits cloud forests and montane ecosystems at high elevations, typically found in areas with persistent fog and high humidity. It requires specific microhabitat conditions within these mountain environments, making it highly sensitive to environmental changes.
