Justification of Red List category
This species is listed as Endangered as it occurs at only one locality and has a very small range, within which the quality of habitat is thought to be decreasing due the spread of invasive plant species. However, should the population continue to be stable or increase thanks to successful conservation action and despite the spread of invasives, the species may warrant further downlisting in the future.
