Large Landslip in Branch Logging Area, at Butlers Corner, Yabba Valley, Queensland.

Selected for Google Maps and Google Earth

After a dry period through winter 2012 and into mid summer 2013, a tropical depression that was formerly Tropical Cyclone Oswald drifted over Mary Valley bringing over 500mm rain over the weekend of 26-27 January.

This large landslide extending over more than 25 Ha resulted from this rain event. This steep hillside has been previously under mature hoop pine plantation that was clearfelled, allowed to lie fallow while forest debris began to decompose, then replanted with hoop pine about 2010. The young trees in this new plantation were 1M-2M in height.

At the foot or tongue of the landslide, the debris extends into mature hoop pine plantation.

This area of plantations are owned by Hancock Queensland Plantations on land leased from the Queensland Government. This landslide is a very disappointing event for HQ Plantations staff as well as for local residents.

The Mary River Catchment Coordinating Committee seeks to promote sustainable and productive land use in the valley by promoting best practice in land use. MRCCC and HQ Plantations will surely be concerned now, to minimise the movement of material from this site, seeking to prevent turbidity in Yabba Creek and Mary River.

Hi Ian* From the group A1- Unique Australia. this is the problem with logging, especially on hill sides. As soon as the roots cant stabilize the soil any more, landslides often occur after a good socking.Excellent document L*. Regards Ebi

A pity that all the new pines are flooded away with the soil Ian. Greetings Berend

Thanks Ebi. Your comment is very pertinent.

The manager of these plantations is very disappointed, Berend.
