thanks Avery
I mapped and photographed the Serrated Tussock (ST) at this site on the 31 August 2023 and again on the 12 November 2024; I also mapped and photographed ST at adjacent site on 31 August 2023, 1 October 2023 and 12 November 2024. I can't carry a knapsack anymore up the steep slopes and the ST are too numerous and big for me to dig out or to cut by hand and spray with small hand held bottle. I wrote to Parks and Conservation Service / Canberra Nature Park North twice to alert them to this infestation/s. PCS rangers change-over is frequent and rumors are that more staff positions have been cut or will be cut. So the best thing to do is perhaps to write to ACT Government and request adequate resourcing to enable PCS to control highly invasive Weeds of National Significance such as ST. I treated 100s of STs downhill, see for instance https://canberra.naturemapr.org/sightings/4610000. I'm fully aware that the ST infestations uphill, if not controlled, will continue to recruit and lead to new infestations in the surrounds.

PCS has also done recent mapping of serrated tussock in the area so, fingers crossed, there might be some action next treatment season. :-)
