Painted Tree's Script Component

When you paint trees/plants, are those trees still considered as a GameObjects?

i have a situation where i have a script inside a tree prefab, then painted it on the terrain, but during runtime, i cannot access the script because i think it doesnt count as a Gameobject anymore.

the scripts works when i manually placed the trees on the scene, but i dont want to put thousand of trees manually :(

Actually no, they aren't GameObjects. The foliage information for the terrain is stored in a particular optimized array format, then the trees are created/transformed/destroyed on the fly based on the distance from the camera. The terrain system wouldn't work very effectively if the trees were like individual prefabs.
