Abstract

Natural spread and aggregation of buffel grass cv. Gayndah and of black (bunch) spear grass on a sandy levee of the Barcoo River in the Blackall district were measured. Buffel grass was markedly better than black spear grass in colonizing areas previously unoccupied by either species. Over 5 years, buffel grass invaded and replaced low-density stands of black spear grass while it only partially invaded high-density stands.
