How did you film Germany's action in Twilight?

I have seen this scene in the movie guide. In fact, they were not standing very high at all. In this photo, there is a big wooden board placed on the tree, and their feet are standing on the wooden board. The board is about 2 meters above the ground. Wires (wires) were indeed hung at that time.

Another scene was shot from a helicopter. That scene was far away, and the person standing on the tree should be a stuntman.

Relevant pictures can be found on pages 66 and 67 of "The Twilight Saga: The Complete Movie Guide".
