How extensive is the hotwire? Is it primarily for the gorillas, or does it prevent the guenons and mangabeys from climbing them as well. This is a much more impressive view of the exhibit than the original photo.
The hotwire is only at the base of the tree. The Sitatungas and Gorillas can`t destroy the trees, but the rest of primates usually use the trees, climbing up the trunks.
