Viv Forbes: The Growing Menace of Trees

Australia is threatened by dangerous trees. They have infested our cities, menace our power lines, invade our grasslands and fuel our worst bushfires.

The meander by Cyclone Alfred through south east Queensland illustrated how bad this danger has become.

Big tall trees smashed power lines and over 450,000 people lost power, some for days; big tall trees crushed cars and closed roads; and in every cyclone big tall trees fall on houses, shops and fences.
