Other claims from this paper (15)
- Observation The Kosciusko Reserve had continuous forb-rich snowgrass and regenerating snowgum woodland.
- Observation Dainers Gap had less continuous snowgrass and no snowgum regeneration.
- Intervention effect Grazing reduced cover of large palatable forbs in the Kosciusko Reserve.
- Observation Forb cover recovered substantially within six years after grazing stopped.
- Observation Tussocks spread laterally in both grazed and ungrazed plots without fire.
- Intervention effect Small grazing-adapted herbs persisted under grazing.
- Intervention effect Without grazing, taller-growing species largely replaced small herbs.
- Observation Shrubs increased rapidly in size, especially on the grazed plot.
- Observation Bare soil did not appreciably decline on the grazed plot.
- Observation Bare soil decreased on the ungrazed plot except the largest patches.
- Observation Intertussock standing crop remained about 0.3 kg/m2 under grazing.
- Observation After ten ungrazed years, intertussock standing crop reached about 1 kg/m2.
- Observation Ungrazed vegetation increased surface soil organic matter.
- Observation Without grazing and fire, snowgrasses and shrubs increased and grazing value fell at Dainers Gap.
- Intervention effect Grazing reduced conservation and grazing values at the Kosciusko Water Reserve.
