Species Profile
Serratula tinctoria, commonly known as dyer's plumeless saw-wort or saw-wort, is a species of flowering plant in the family Asteraceae.
Dyer's plumeless saw-wort faces severe decline primarily due to habitat loss from agricultural intensification and changes in traditional land management practices. The species depends on specific grassland conditions that are increasingly rare due to abandonment of extensive grazing systems and conversion of semi-natural grasslands to intensive agriculture or development.
Key Facts
Habitat & Distribution
S. tinctoria grows in various soil types overlying a range of rock types but is almost always confined to semi-natural vegetation in habitats with low levels of soil fertility and disturbance. It typically favours moist soils with full sun to partial shade, growing in grasslands, mires, open woodland, and scrub as well as their ecotones.
Threats
IUCN Red List: Critically Endangered
Dyer's plumeless saw-wort faces severe decline primarily due to habitat loss from agricultural intensification and changes in traditional land management practices.
