This video shows how to ascend a tree with many branches safely, using a combination of rope throwing and climbing. The climber uses one rope and a prussic loop. The climber pulls himself upwards by the rope while using the stem only as a support for his legs while ‘walking’ upwards. The video is most useful for practitioners (seed collectors/tree climbers).
