I'm thinking Acacia longifolia, but these two plants were 100m from the urban edge in the middle of a native Blackthorn thicket, under Apple Box - how did they get there?

The seed may have come in in washed river sand or mulch.

This species is very common on Isaacs Ridge. The broader leaf form like this is mainly in the cleared area where the pines used to be but there are several finer leaf forms as well. I don't think you can blame sand or mulch.

I suppose seed eating birds could possibly spread it. Another possible means is ants that like eating the fleshy arils of the seeds but that is pretty short distance.

Thanks Betty and Mike - I will remove these plants next weekend- It never ceases to amaze me just what plants turn up where.

If I did that on Isaacs Ridge there would be parts looking quite bare. Most of the Canberra Nature Map sightings are from Isaacs/Mugga but Atlas of Living Australia has records from Black Mountain etc. Friends of Black Mountain removed a lot as escapees from the Botanic Gardens but some records date back to 1964.

Michael
we have patches of Golden Sydney Wattle on Mt Majura several 100m away from Mackenzie St backyards, some of the old are 7-8m tall.
The older ones may have been planted. I currently remove all young growth in the surrounds and will tackle the older ones at some stage (frilling).

Thanks Waltraud,
One of the benefits of CNM is getting to know what is around.
