The species page says this is an environmental weed in the ACT and Victoria. Is this correct? Most sightings seem to be Ainslie/Majura.

The species is local according to the ACT Census of Vascular Plants 2017. When I compile the Mts Ainslie Majura Flora list updates I follow the latest Census rather than various resources. I'm not sure which Census / resources CNM uses to make decisions reg the localness of species. Perhaps it would be a good idea to publish the info / resources somewhere so that everyone can see on which basis descisions are made?

Thanks Mike - Waltraud is correct re being considered as a native. II have changed the info in the species page.

It showed as native (leaf symbol) but the species page had just too much information. Flora of the ACT Burbidge and Gray 1970 lists it as A. armata and says "uncommon in the ACT, eg lower slopes of Mt Ainslie and possibly not native to area". ALA shows some early records but these could be in agricultural areas. I was interested because A. paradoxa has been planted recently in Isaacs-Mugga.

I think to remember Greg Baines mentioning the species to occur north of Mt Majura in the Gooroo - Mulligans Flat area. I was interested whether we could use the species to replace the many hawthorns firethorns African boxthorns Sweet Briars etc etc that we removed from the northwest slopes of Mt Majura particularly east of The Fair. From my observation of A. paradoxa that grows behind Mackenzie Street and around the old Ainslie landfill site, the species provides excellent foraging habitat for little woodland birds.

"Native" is an interesting term: (1) Is the species native to the ACT / the Bioregion? (2) Is it part of the vegetation type? for instance several Leptospermum and Grevillea species naturally occur in ACT but not on Mts Ainslie / Majura where I consider them as garden escapes. In addition there may be changes based on new research findings; for instance, to my knowledge A. decurrens was considered a local ACT species times ago. Who knows what the future (or the community of botanists ) holds for A. paradoxa...

Waltraud and Mike
Kangaroo Thorn is a widespread southern Australia species. ACT records are mainly on Mt Ainslie and Mt Majura, but it occurs in the hills above Queanbeyan and south of Googong Dam. Greg Baines and I consider it as a local ACT species and a good one to use when wishing to enhance woodland bird habitat, even on Isaacs Ridge.
