Run-off and soil movement on mid-slopes in north-east Queensland grazed woodlands (Scanlan et al. 1996), Greenvale (1996).

Level 1 General description


This study collected runoff, sediment loss data from six woodland sites over unbound catchments in grazed and exclosed pastures. The aim was to quantify run-off and soil movement in grazed woodlands.

Methods (brief)

The study was undertaken on six woodland sites around Charters Towers in the Dalrymple Shire, north-east Queensland. Each of the sites had two treatments: exclosed and grazed. Slopes ranged from 1.5 – 5%. Two 10 m wide gerlach trough were placed perpendicular to the slope in each treatment. Bedload material settled in the troughs was collected fortnightly in summer and monthly in winter. A tipping bucket mechanism connected to a data logger was used to collect data on runoff.

Key findings (brief)

Runoff and bedload losses were greater in grazed treatment sites than exclosed treatment sites. BOPER sites (dominated by stoloniferous grasses) had less runoff and less soil movement than HECON sites (dominated by tussock grasses). High bedload soil loss, soil movement rates, sediment concentration and runoff percentages were associated with cover <30 %.
