Conifer roots

A great forestry commision report on tree rooting depths in differing soils, will see what else i can digg out:icon14:

BS 5837 calculation - take the DBH measurement and times by 12 this will give you the root protection zone, this is implemented in development situations......

 

if this area encroaches or nearly encroaches on the house then you can say it could effect the building.

 

this is only a quick rough guide for you and like i said has many dependants..

 

Ok i feel silly now but DBH?? Height?? sorry...

Diameter at Breast Height of stem . If multi stemed tree the widest stem..

[Husqvarna King]

Diameter at Breast Height of stem . If multi stemed tree the widest stem..

 

You're a star...where do i post the beer??

[Lee Winger]

NHBC guidlines are good for reference

Christreeroot - Bs5837 takes stem diameter at 1.5m. (Higher than the 1.2m DBH used by foresters) and the calculation for multiple stems is 10 x basal diameter above the root flare..

and the calculation for multiple stems is 10 x basal diameter above the root flare..

 

?????

I'd stay clear of making any comments about the possible influence of the trees on the house.

 

 

Its a very slippery slope...

RPA multistemmed trees:

Tree with more then one stem arising below 1.5m above ground level basal diameter x10 (measured immediatly above root flare)

 

Multiplyed by 10 not the widest stem at 1.5 x12
