Thesium psilotocladum

Unknown

Overview

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

Thesium psilotocladum faces severe threats from agricultural expansion and intensive farming practices that have destroyed much of its native grassland habitat. Urban development and infrastructure projects continue to fragment the remaining populations, while changes in traditional land management practices have altered the ecological conditions this parasitic plant requires to survive. The species' highly specialized nature as a root parasite makes it particularly vulnerable to habitat degradation.

Threat summary

Habitat

This species inhabits dry grasslands, meadows, and open woodland edges in temperate regions. As a parasitic plant, it requires specific host plants and thrives in areas with traditional extensive grazing or mowing regimes that maintain open, species-rich grassland communities.

Frequently asked questions

Why is Thesium psilotocladum classified as Critically Endangered?
Thesium psilotocladum is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Thesium psilotocladum faces severe threats from agricultural expansion and intensive farming practices that have destroyed much of its native grassland habitat. Urban development and infrastructure projects continue to fragment the remaining populations, while changes in traditional land management practices have altered the ecological conditions this parasitic plant requires to survive. The species' highly specialized nature as a root parasite makes it particularly vulnerable to habitat degradation.
Where does Thesium psilotocladum live?
Thesium psilotocladum occurs in Spain. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Thesium psilotocladum?
The main threats to Thesium psilotocladum are 2.3, ai-1, ai-2, and ai-3. The full IUCN-classified threat record for this species is detailed on the species page.
