Entanglement is usually considered to be fragile against local noise. However, we show that situations can be found where entanglement remains constant over time in certain quantum many-body systems. We also connect the behaviour of entanglement with the propagation of noise via quantum many-body systems, in terms of the Lieb-Robinson's bound. Additionally, we point out certain interesting scale-invariant features of the behaviour of entanglement in specific quantum many-body systems.
