tree cavities

[Iowa]

Hey Folks,

Isn't there a trunk or branch cavity/diameter/sound wood ratio to determine if a trunk or branch should be removed? If so I'm trying to find a source for this information. Thanks.

yes there is. I can't remember where I saw it. Maybe in arborist news.

Iowa,

I can't remember where I copied this from, so I can't give them proper credit. But, there is an interesting strength loss chart on page 19 that might answer your questions.

"The body language of trees", Claus Mattheck and Helge Breloer. Try to find it at www.tso.uk/bookshop
Great book that should be mandatory reading for arborists.

Read the December issue of Arborist News. Jerry Bond thoroughly debunked the use of shell thickness as a criterion for tree safety. Strength loss formulas are one very small part of tree risk assessment.

See, and work with, the whole tree!
