Description

Microlaena stipoides var. stipoides (Labill.) R.Br. (Microlaena) is a tufted C3 native Australian perennial grass with a short rhizome that can form dense lawns. Microlaena has a wide geographic distribution throughout southern Australia, particularly in the temperate, high-rainfall tableland areas (> 550 mm AAR) of south-eastern and western Australia where is considered to be important for the grazing industries because of its extended growing season in higher rainfall areas, persistence over many years and persistence through drought. Although Microlaena has an important role in the stability of grazed native pastures, little is known about this grass in grazed communities. This study focused on phenology, seed rain, seed bank, seed germination and seedling recruitment. The overall aim was to assess the likely importance of seeds for the maintenance of Microlaena within swards where it already exists.
