This is the kind of long term environmental stability that many creatures need to survive, that can be lost with even the most minimal of disturbances, such as a dam 2000km upstream that changed the water depth where the owls are by a few cm. This could completely negate the presence of young salmon. Loss of the old growth trees, even if replaced by new ones wont be a suitable replacement place for the owls to live.
