Anything that lasts more than a few weeks will have some form of plastic blended in; which makes it NON Biodegradeable.
Degradable plastic exists, but this just becomes smaller plastic particles - which is what all the fuss is about with regard to ocean pollution.
IMO tape contravenes the "leave only footprints" rule of thumb. But then so does bolts & chalk.
