Pityrodia sp. Marble Bar

Status: Endangered on the EPBC Act list

Many-branched shrub to 2m tall with opposite, grey, densely hairy leaves and large, pink, tubular flowers that have darker pink markings in the lower lobe and in the throat and a darker pink calyx. Flowers appear from July to September. Plants are uncommon through the landscape, usually occurring as isolated clumps of individuals on very steep sandstone slopes. Most populations are small (<10 plants), although some contain relatively large numbers of individuals (>200 plants) (Woodman Environmental Consulting 2013). Dispersion through the landscape is dictated by the availability of suitable habitat. Pityrodia sp. Marble Bar is a long-lived species. It resprouts from woody rootstock following fire, even high-intensity fire, with seedlings also observed at a number of locations adjacent to resprouting individuals (Woodman Environmental Consulting 2013).

    Weeds suppress early plant growth by competing for soil moisture; nutrients and light; as well as increase the fire hazard due to the easy ignition of high fuel loads.

    If fire frequency is increased the soil seed bank could be depleted before juvenile plants have reached maturity.
