This specimens Stem and roots were treated with Glyphosate," cut n dab" , it was not "dug out". I don't think this specimen is a regrowth from a previous weed treatment, most likely an original / new specimen. Yes it was growing under Exocarpus @ Clancy's track not far from the water Dam site here.
hi https://canberra.naturemapr.org/users/8081, many thanks for digging this out and yes, my comment referred to the further west (downhill) specimen. It just shows that the figs are spread like other fruit trees and that you can expect them to grow under tree canopy in rather high nutrient soil with reasonable moisture. the number of Currawongs have increased dramatically since the development of The Fair - I suspect them are the culbrits spreading the figs and most likely the Callery pears, tomatoes, etc which we find in increasing numbers..... cc MPW
@waltraud, I think the one you are referring to is https://naturemapr.org/sightings/4560954, which is a bit further west. (Found record in species search on CNM, but had to go to the list which gives your name) and on species search of ALA (which gives a map). Ficus carica is on the ACT list of invasive alien plants (which relies on sightings) but not on ACT Plant Census (which relies on Herbarium accessions).
The specimen is certainly not a native of the area, and yes Max, there was a fig tree - the edible mediterranean Ficus carica - where we removed Cleavers, Black Nightshade, tomatoes (!) etc under Exocarpos trees. I took photos and recorded on CNM however since the mapping tool is removed from CNM, it would take me long time to find it again. I observed Fig trees (Ficus carica) in the Majura pines close to the border with nature reserve at the ridge and I think fruits are spread by birds, most likely Currawongs. The Census of Vascular Plants of the ACT doesn't list Figs, native or exotic... Obviously the specimen you recorded was tackled before but has re-sprouted.
