​​​Craspedia paludicola (swamp billybuttons) is a robust herb in the daisy family that grows in open wet swampy areas or at the edges of water bodies or courses. In Tasmania, the species is known from 12 locations scattered in mostly lowland areas in the eastern half of the State, and in montane areas in the Central Highlands. While rarely encountered, the species can be abundant, but most occurrences are small. Its distribution and abundance appear to be regulated by conditions to maintain or disturbance to create open recruitment niches, as well as protection of this palatable species from browsers. The species is at risk from climatic changes that risk drying of its preferred wet habitat. It is also at risk from land clearing.

  • This perennial herb is most readily detected when flowering, the peak period occurring from October to early January.
  • Tasmanian occurrences are in open wet areas that are often temporarily inundated e.g. bogs, swamps, ponds, ditches and the edges of lakes, lagoons, rivers, creeks and streams, in vegetation ranging from open wetlands, marshland, rushland, sedgeland to grasslands. The altitude of sites ranges from sea level, with lowland sites restricted to the eastern half of the State, to an elevation of 1200 m a.s.l. in montane sites in the Central Highlands.​​​

Permit: A permit is required under the Tasmanian Threatened Species Protection Act 1995 to 'take' (which includes kill, injure, catch, damage, destroy and collect), keep, trade in or process any specimen or products of a listed species. Additional permits may also be required under other Acts or regulations to take, disturb or interfere with any form of wildlife or its products, (e.g. dens, nests, bones). This may also depend on the tenure of the land and other agreements relating to its management. ​​​​​
