This was an early record (the first ?) of Madia sativa in Canberra Nature Map, soon after it had been discovered as a new species for Namadgi NP and the ACT.

John just checking that this is a different location along the Naas Valley Firetrail than the recently reported infestation near Franks and Jacks Hut.
