David Holmgren explaining a low cost technique for revegetating eroded gullies without heavy machinery or chemicals. The technique turns thick, fire-prone blackberry cover into useful fire-resistant trees on what was a landscape completed denuded in the gold era. David Holmgren is co-originator of the permaculture concept and lives next to Spring Creek Gully in Hepburn Springs, Victoria, Australia. See http://www.holmgren.com.au/ for more information.
