I hit the ball into the rough which was shrubby trees and thin grass. My ball was next to a small tree. In the tree and hooked onto a branch was a white plastic bag which sort of flapped in my face when i took my stance. The caddy quickly removed it. I treated the bag as a movable obstruction and all was OK. Area was not marked as a hazard.
But what if what was stuck in the tree was a dead and withered branch which also annoyed or troubled me? Could i remove that without penalty?
