The Good Old Fashioned Tripod.

a recognisable symbol. safe and easy to construct open to adaptation and variation needs an athletic bunny

Select the tallest, thinnest poles that can be erected by the team available (Yes! Shock! Horror! This involves killing poor little baby trees etc. Remember: cost/benefit!!)The tripod can be walked into position after erection one leg at a time. Anarcho-politics aside, it helps if one person stands ALMOST under the apex and directs the huffing and puffing.The pole butts can be retained in shallow holes or rigged and a comfy seat arranged.

Locking on to the underside of the apex is reasonably effective though extremely uncomfortable. Escape routes into trees or onto various mono or bipod combinations are more effective. These provide a platform for the bunny to hop around and avoid arrest. They are safe but unstable if cut. Some sort of harness and rope are required to leave hands free for installation.
