Table 3. Ten most common grass species according to their frequency, expressed as their occurrence in plots. Number of plots (n = 60) in which the species was recorded and its mean cover within them (mean ± S.D.) are given. Life history data and grazing value were taken from van Oudtshoorn (2018), see text for details. Species were classified as annuals if they grow for one season, as weak perennials if they grow for two to five seasons, and as perennials if they persist for longer than five seasons.
