Several gorilla statues have had to be moved due to damage and safety fears.
They have been distributed around the island as part of the Go Wild Gorillas trail, which marks Durrell's 60th birthday.
Despite a successful start and great response from the public, organisers say they have received increasing reports of damage to the artwork due to people climbing on the structures, despite signs instructing them not to.
Concerns have also been raised that people are causing traffic problems whilst visiting the gorillas, parking on yellow lines or putting themselves at risk by taking photos in the road.
To alleviate any risk to the public, two gorillas have been relocated this week - Long John Silverback has a new home at Jersey Harbour, and Jambo Sana now has a sea view at Greve de Lecq beach.
Groovy Gorilla, next to Mont Orgueil Castle in Gorey, has proven very popular, which those behind the trail say has led to irresponsible parking nearby.
