Probably Prickly pear Cactus, Growing within 30 m of Hackett Housing Fenceline with Nature Park. This is a Repeat sighting for this area. Garden "Escape"...
Thanks Waltraud for explaining about this "Robot Moderator" Is this some kind of A.I. assisted function I take it ? Great idea eventually as it "machine learns"... In the meantime " Carbon AI " has a bit of a learning curve ahead ( Opuntia and Crassula are of course quite different plants altogether). Good to know though, given the Huge Database that CNM has to work through, so I encourage the AI function, which in the long run should save the Human Moderators time and effort 😉
