I am involved in a project to put some small wooden structures like nesting boxes out
in some woodland. The Desire is that they should be 100% (or at least 99%)
biodegradable, so they last as long as poss but ultimately rot away to nothing. Fixing
them in trees with synthetic ropes or straps is therefore obviously a complete no-no.
So traditional rope is required.

There's a bewildering array of different materials - coir, hemp, flax etc and some
treatments as well like tarred rope. Does anyone know what is a good choice here for
just lasting a few years out in the weather? Is it better to have thicker rope for
lasting, or just strong enough to do the job?

Drill an appropriate sized angled hole in the trunk, insert a length of wooden
dowel and suspend the nest box from that,

....

Actually you don't even need dowel. Just rough pegs fashioned from the same
species of timber as the boxes. And level rather than angled holes. If the pegs
are fittted securely to the box but a loose fit in the hole then when the box
eventually falls down it should take the peg down with it.


Repeat as necessary

A shallow hole won't harm the tree in any way.
