Vegetation a Vital Windbreak

 IF THE relaxation of planning controls over removing vegetation goes too far in developed areas, this could lead to problems for fire protection.

In typical residential areas, most trees are within 10 metres of a dwelling - the zone proposed for relaxing controls. If a significant proportion of these trees were removed in places like the Dandenongs, there could be a significant increase in wind speed.

Wind is critical to fire behaviour, particularly in catastrophic conditions, when atmospheric conditions become more important than fuels.
