Corunastylis insignis

Status: Critically Endangered on the EPBC Act list

The Wyong midge orchid 1 occurs within the Wyong Local Government Area on the NSW
Central Coast. The species occurs within the Sydney Basin Bioregion and the Hunter-Central
Rivers Catchment Management Authority. The species has been recorded from Chain Valley
Bay (found at two localities), Charmhaven (found at three localities) and Lakehaven (no
flowering plants recorded in the past 10 years). Field inspections throughout 2013 found less
than twenty plants across all known localities (Branwhite, pers. comm., 2013).
In December 2013, the primary site at Charmhaven was impacted by construction activities
(Branwhite, pers. comm., 2014; Mitford, pers. comm., 2014; Smith, pers. comm., 2014). Several
acts of vandalism, such as destruction of fences, also occurred at this site (Payne, pers. comm.,
2014). However, the extent of damage to this population can not be ascertained until plants
flower in the future (Branwhite, pers. comm., 2014; Mitford, pers. comm., Payne, pers. comm.,
2014; Smith, pers. comm., 2014).

    Inappropriate fire regimes also pose a threat to native orchids (Duncan; 2012).
