In grassy woodland; approx 400 Serrated tussocks in an area of approx. 250m2; mapped with Field Maps Not-Treated Weeds. Friends of Mt Majura mapped serious ST infestation uphill and south of Blue Metal Road for years but unfortunately volunteers mapping is ignored, although a couple of Sts were sprayed along the road by contractors. This high density is east of the high transmission power line where ST was always a problem (disturbance).
