As always after an incident like this, the council says it will launch a "full investigation". By its own admission, this council says it only loses about four such trees a year in similar circumstances. But how many is it losing a year because its construction site TPZ's (Tree Protection Zones) are inadequate (see post below)? Many more than four I'll wager!
The council also says it loses around twenty juvenile trees in similar circumstances. But how many a year is it losing due to lack of watering and maintenance by its own staff?
The City of Melbourne do it right. They keep accurate stats of all their losses and as a result they are losing less than five percent of their new tree plantings.
It's not hard. You just get out of bed one morning and decide to be accountable.
