With some annual exotic grass. This is one of the Friends of Mt Majura, Mondays @ The Fair volunteer team "Cleavers under native Cherry Ballart" project sites where volunteers treated Cleavers, Black Nightshade and other nutrient loving herbaceous weeds, followed by planting and direct seeding of Weeping Grass (WG), Microlaena stipoides (WG). The idea is that the perennial WG which loves to grow in shady positions under tree canopy, in moist sits such as drainage lines and which copes with nutrient enriched soil will out-compete annual exotic grass; herbaceous (non-grass) weed regrowth can be sprayed with selective herbicide or manually removed. WG seems to be quite competitive and surprisingly little grazed and it withstood dry conditions and heat waves in summer. I'll take close-up photos at next opportunity.
