Little published information is available on the levels of soil nutrients and soil moisture on remnants of native (Basalt Plains) grasslands. This study investigated the association of soil nutrients and moisture with stands of the native grass Themeda triandra (Kangaroo Grass) and the noxious weed Nassella trichotoma (Serrated Tussock). Both mature and immature (i.e. recently burnt) stands of T. triandra and N. trichotoma were investigated, on disturbed and undisturbed soil.
