Tree Platform

Tree Platforms are elevated structures that can only be built on certain types of trees, it was added in update v0.10 to The Forest.

Gameplay
The tree platform that can be built with or without a built in climbing rope, using the  key on the blueprint before it is built. As with the tree house and the alpine tree house they must be built in a fully grown tree. Tree Platforms require 7 logs to be built and once completed can be climbed via the attached rope. They differ from the tree house and alpine tree house in the fact that they will provide no shelter or home symbol on your map. Nonetheless, they are a cheap way of avoiding cannibals and provide a decent vantage point for hunting. If you press  on the blueprint, you can choose whether it has a built in climbing rope or not. The tree platform can be attached to other elevated platforms, the rope is removable during construction, and there is an anchor mark.
