Botanical composition of a phalaris‐dominant pasture 5 years after the introduction of intensive rotational grazing
Phalaris ( Phalaris aquatica) is a significant grass component of many sown permanent pastures in the high rainfall zone of southern Australia ( >600mm annual average rainfall), including the lower south east of South Australia.Its ability to persist through the summer‐dry, its high growth rate and the observation that it grows well on the shallow, heavy clay/loam soils of high pH (8.0-8.5 ) that appear to be less well suited to most other perennial grass species often promoted for the region, all help explain its widespread use in the area.Although it has been widely adopted, there has been relatively little work undertaken on the effects of rotational grazing on this species.Virgona et al.(2000) is the most recent example that studied the effects of differeing grazing management, concluding that rotational grazing can be used to increase or maintain phalaris in summer‐dry environments.This paper reports a 5 year study of the effects on botanical composition of changing the grazing management of a phalaris‐dominant pasture from many years of set stocking with sheep and cattle to intensive rotational grazing predominantly with cattle.
