SUPPORTERS of a row of mature Hills figs in Laman Street, Newcastle, are putting their faith in a ground-penetrating radar survey they hope will show the trees have stronger roots than first thought.
The trees are likely to be the main subject of discussion at a two-day design workshop or "charette" organised by Newcastle City Council for March 19 and 20.
Cooks Hill GP Caitlin Rashke, a member of the Laman Street Action Group formed to save the trees, said yesterday that the radar survey contradicted earlier advice to the council that the trees lacked "radial" roots growing out under Laman Street.
Newcastle City Council infrastructure manager John Johnston confirmed that the radar survey indicated the presence of roots but said the council had dug at some spots without finding any.
The radar spat is the latest round in a long-running battle over the Hills figs, a rainforest tree that grows naturally in north Australia and Asia.
Fourteen Laman Street figs were destined for the chainsaw until a rescission motion in December gave them at least a temporary reprieve.
Council future city director Judy Jaeger said 70 people would take part in the charette, with one third coming from government and council, one third from nearby residents and businesses and one third from a random sample of Novocastrians.
