Eryngium ovinum (blue devil) is a perennial herb in the Apiaceae (carrot) family with distinctive spiny foliage and metallic-blue flower-heads. It is known in Tasmania from about 24 sites in the State’s southeast and east, usually growing in fertile heavy soils in grasslands and grassy woodlands below about 350 m elevation. The species is poorly reserved, with the majority of sites on unsecured private land and most subpopulations are thought to be small, making them subject to inadvertent or chance events. The risk is exacerbated as the species may become confined to rootstock or the soil seed store during unfavourable periods. Eryngium ovinum is subject to a range of threatening processes, including historical and contemporary depletion and modification of habitat, competition by weeds, and inappropriate disturbance regimes (e.g. grazing, fire and mechanical disturbance).
- Important: Is this species in your area? Do you need a permit? Ensure you’ve covered all the issues by checking the Planning Ahead page.
- Important: Different threatened species may have different requirements. For any activity you are considering, read the Activity Advice pages for background information and important advice about managing around the needs of multiple threatened species.
- As flowers are required to confirm the identity of this short-lived perennial herb and flowers will aid detection, surveys are best conducted during the flowering period, November to January. However, the other species in the genus in Tasmania, Eryngium vesticulosum, occurs in salty, swampy habitats as opposed to the dry forest and grassland habitat of Eryngium ovinum allowing surveys to be conducted at any time, except in dry years when plants may largely die back.
- In Tasmania, Eryngium ovinum occurs in gullies, roadsides, Themeda grassland and open grassy woodlands, often in damp clays in the south east of the State.
