Default Re: Tree protection zones| Critical root zones| Critical Root Radius| AUSTRALIA

I hope she does and they do drop in...and if they feel that 10X DBH is an acceptable one size fits all, that will provide sufficient protection for older sensitive significant trees to the community down there that they present their reasoning....looking forward to the justification.

As you abley pointed out even 1 or 2m difference in radius makes a big difference in volume of roots and soil protected.

1m diameter at breast hieght = 10m radius (I'm presuming its radius not diameter!) thats 314 square metres

1m dbh of a tree intolerant of root damage in mature age class = 15m radius....thats 707 square metres.....big difference eh?
