I'd not want to be the bird in the box when your rope gives way in the
middle of a gale.

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

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?

How very bonkers.

Yes there is an element of bonkerishness but I believe it's a worthy
cause.
