Overview

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

Thyme Dodder faces severe decline due to the widespread loss of its specialized heathland and chalk grassland habitats across Europe. Agricultural intensification and abandonment of traditional grazing practices have eliminated many of the flower-rich meadows where this parasitic plant depends on its host species, particularly thyme and other small herbs. Urban development and habitat fragmentation have further reduced available sites, while changes in land management practices have altered the delicate ecological balance required for both the dodder and its host plants to thrive.

Threat summary

Habitat

Thyme Dodder inhabits dry, nutrient-poor grasslands, heathlands, and chalk downs across Europe, where it parasitizes low-growing herbs including thyme, clover, and gorse. This annual parasitic plant requires open, sunny locations with sparse vegetation and well-drained soils that support its specific host plant communities.
