Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2012
Assessor/s: Upson, R., McAdam, J.H., Broughton, D.A. & Clubbe, C.P.
Reviewer/s: Hilton-Taylor, C. & Bilz, M.
Contributor/s: Lewis, R.
Justification:

Locations such as Weddell, Steeple and Grand Jason Islands demonstrate that where grazing pressure is removed, Calceolaria fothergillii can become frequent to common across a broad range of sites. Where grazing pressure is high, C. fothergillii is largely restricted to coastal cliff and slope and upland sites. However, given its wide range and that it is reasonably common and stable, this species is assessed as Least Concern for now.

It is likely that past grazing pressures reduced the extent of this species, but that reduction would have mostly occurred more than ten years ago. Grazing is likely to continue to be a threat, but it is not known whether direct grazing is the problem or whether the effect on the species is a result of habitat loss or modification. Ongoing monitoring and periodic reassessment of this species is required.

Population [top]

Population: Population data does not exist for many of the records available for this species but extrapolating from those data available it is estimated that the population of C. fothergillii consists of over 5,000 mature individuals.
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: A perennial herb that prefers open, well-drained, sandy soils and where peat cover is thin; predominantly within dwarf shrub heath and coastal cushion heath but also within inland rock habitats, maritime cliffs and slopes, coastal feldmark and (at ungrazed sites) in coastal grassland. Occurs across an altitudinal range of 0-174 m.
Systems: Terrestrial

Threats [top]

Major Threat(s): Grazing is the principal threat to C. fothergillii.
