Western Lowland Gorilla enclosure (Gorillarium)

Does the temporary barrier prevent closer access to the areas around the Gorillas? So 'restriction-related?

@Pertinax Yes, the barriers are all along the enclosure, to keep a social distance from the Gorillas. The two Gorilla groups at the bottom of the park (Sammi and Djanghou's groups) are both currently off-show as social distancing from the gorillas is not possible in that area.
