[CANUFNET] Looking for advice on metal in trees and trees on slopes

[Astrid Nielsen via CANUFNET]

Hello fellow Canufnet members,

I came across this tree today...the metal basket has been there for quite
sometime, and there are large screws holding it in. There are also other
nails in the tree. I am looking for an opinion on what is the best course
of action. I am thinking that part of the basket that has not grown into
the tree should be removed, but any parts where the tree has started to
grow around should stay. In other words, if removal exposes the cambium
layer, it should stay. Any thoughts on this?

On another topic, I am looking for good references that look at the
structure of tree roots growing on steep slopes. i.e. how do they grow
differently than trees on flatter ground? I would like to apply this
information to help me predict the impact of trees on slopes that will be
exposed to major construction. The most important factor that I am
interested in is stability.

Thanks for your help,

Astrid
