Description
Changes in basal area and soil water extraction were examined in four perennial grasses, Phalaris aquatica cv. Sirosa, Dactylis glomerata cv. Porto, Festuca arundinacea cv. Demeter and Danthonia richardsonii cv. Tarana. Treatments were factorially arranged with four species, three different grazing intervals (2-, 5- and 8- weeks) and two watering regimes (rainfed and supplementary water)and were imposed from early spring to mid-autumn in 1994/5 and 1995/6. In 1994/5, the basal area of all species declined except for the native, D. richardsonii under rainfed and watered conditions. The grazing treatments had no effect on changes in basal area in this season. In 1995/6 the basal area of D. glomerata and F. arundinaceae increased under watered or the 5 week grazing treatment. The basal area of D. richarsonii declined in 8 week grazing treatment but increased in the 5 week treatment. The results are dicsussed with respect to grazing management under drought conditions.
