endemic to the Canobolas - Prostanthera gilesii

Endemic Species

A most interesting feature of Mt Canobolas biodiversity is the unfolding discovery of many endemic species.  At least nine species are found in the wild within the SCA and immediate surrounds, and nowhere else in the world. These species depend entirely on the SCA for their survival.

At least nine species are considered to be endemic to the Canobolas volcanic complex. These include four plant species, Prostanthera gilesii, Eucalyptus canobolensis and a Bulbine sp. and a Prasophyllum sp. [both currently in the process of being described and named]. Three lichens, Gyalideopsis halocarpa, Sarcogyne sekikaica and Xanthoparmelia metastrigosa are endemic to the SCA as is Cephalofovea pavimenta, the Mt Canobolas Velvet Worm and an unnamed Planarian Worm. Other taxa, including shrubs in the genera Asterolasia and Phebalium, still under study, are likely also to be endemics, along with several unnamed insects.

Two of the endemic plants E. canobolensis and P. gilesii are listed as threatened and one endemic lichen is part of the Endangered Mt Canobolas Xanthoparmelia Lichen Community. It is highly likely that the remaining non-listed endemic species would also qualify for threatened status if they were to be nominated.

The endemic shrub Prostanthera gilesii [formerly P. sp. C] (Giles’ Mintbush) is only known from two small colonies and has been listed as Critically Endangered under the BC Act.
