09057: Post-fire restoration of Bennett Brook to protect water quality and the endangered southern brown bandicoot
The 140 ha Bennett Brook Reserve takes in the 17 km-long Bennett Brook, a conservation category wetland.
The reserve is a Bush Forever site and contains threatened species-including the southern brown bandicoot-as well as weeds of national significance. Revegetation of the reserve has been ongoing since 1995.
Fires in January 2010 destroyed 10 ha of vegetation including 3 ha previously revegetated and 2 ha of untreated blackberry. Fires provide an opportunity to eradicate blackberry and revegetate with native vegetation, restoring habitat and preventing erosion.
It is imperative to the overall condition of the reserve that weeds are controlled in burnt areas to reduce competition and allow regeneration of native species.
With the help of funding from the State NRM Program, Perth Region NRM eradicated blackberry and reestablished indigenous habitat in the burnt section of the reserve. Weeds in other areas of the reserve, including lantana at Success Hill, were also removed.

Major project achievements
- Improved cover of native riparian vegetation and reestablished indigenous habitat within the burnt section of the reserve: 4073 rushes and sedges planted in Bennett Brook floodplain; 7581 indigenous species planted in riparian buffer zones; local rush and sedge direct seeding trials conducted in the burnt floodplain using locally collected seed.
- Prevented erosion in the burnt section of Bennett Brook to reduce the nutrient and sediment load entering the waterway and Swan River.
- Prevented competition to native vegetation by controlling weeds, including arum lilies, japanese peppers, figs, typha, giant reed, morning glory, bridal creeper, watsonia, juncus microcephalus, pampas, nightshade, fleabane and broad-leaf weeds throughout the wetland areas of the reserve.
- Reduced fire risk through control of weeds within the reserve.
- Eradicated blackberry in the burnt section of Bennett Brook.
