During summer/autumn and winter 2014, all sites (except Site 2*) have been sown with warm season active and cool season active native grasses:
Warm Season Grasses – Bothriochloa macra (Red-leg grass)
Themeda triandra (Kangaroo grass)
Chloris truncata (Windmill grass)
Aristrida behriana (Brush-wire grass)
Cool Season Grasses - Microlaena stipoides (Weeping rice-grass)
Recent monitoring has seen excellent germination on some sites. The Weeping rice-grass emergence has been outstanding on Sites 6, 7 and 8, however, we are still waiting for a combination of >25 degree daily temperatures and good soil surface moisture to activate the germination of the Red-leg grass, Kangaroo grass and the Brush-wire grass.
At Site 4, the extreme February rainfall event (160mls) and some later off-target roadside spraying has resulted in some of the Red-leg grass florets being swept from the site. The remaining florets that germinated have emerged to cover parts of the site with a carpet of green.
The challenges will be summarised in a later update.
*Due to site preparation problems, action on this site has been deferred.
