In grassy woodland, several separate infestations from a few vines to a thicket of approximately 30mx30m. Friends of Mt Majura (FoMM) reported infestations of Blackberry, a Weed of national Significance, around this part of nature reserve several times in the past years. It seems that some foliage spray was carried out: there are some dead vines around however practically all have regrown. Over the Federal highway FoMM reported large infestations over the past years; see for instance https://canberra.naturemapr.org/sightings/4392261 and comments.
