02Description

Species Profile

Hieracium onosmoides is a rare perennial herb in the hawkweed family, characterized by its distinctive hairy leaves and bright yellow composite flowers that bloom in summer. This endemic plant species plays a specialized ecological role as a nectar source for local pollinators and contributes to the unique botanical diversity of its restricted range.

Hieracium onosmoides is threatened primarily by habitat loss and degradation due to agricultural intensification, urban development, and changes in traditional land management practices in its limited alpine and subalpine range. The species' extremely restricted distribution makes it particularly vulnerable to localized threats and environmental changes.
