pale golden moths

The pale golden moths orchid is endemic to south-eastern Australia and displays a disjunct distribution between Victoria and New South Wales. In Victoria this species is found in two populations; the larger containing an estimated 8000 plants, is reserved within the Alpine National Park and the smaller population of around 50 plants, grows on a roadside near Abbeyard. In New South Wales the pale golden moths orchid occurs in the Kybeyan area, Monaro Tableland, and is restricted to a single population containing an estimated 130 plants. The pale golden moths orchid can be found growing in grasslands, sub-alpine grassland and sub-alpine open and sparse woodland. Weed invasion, grazing by feral herbivores and stock grazing as well as physical disturbances by off-road vehicles are known threats to this species.

    Fire Timing and potential The role of fire for the pale golden moths orchid is not well frequency understood.

    Too frequent fire may pose a threat by altering the habitat; removing organic surface materials and negatively impacting pollinators and mycorrhizal agents.

    However; the species may require regular burning to maintain the open herbaceous vegetation that it prefers (DSE 2003) and too infrequent fire may also be a threat.

    Pile burning was identified as a potential threat at the NSW site in (NGH Environmental 2004).
