This map is slightly later than the c.1994 one linked above. It includes the Crested Porcupines (imported in 1995) and Servals (two animals obtained from the North Brighton Zoo when it closed in 1996 - they were only on display for a short period and then remained off-display until their deaths in 2011); and also features the "African Lion Habitat" to the right of the Patas Monkeys which was originally built (in part) to house an elderly lioness from the North Brighton Zoo. The Patas Monkeys left the park in 1997.
The Sitatunga appear to have left the park by this time (only the Addra Gazelles and Springboks are labelled).
Note the animal symbols - Waterbuck is represented by a Water Buffalo silhouette, and the lemurs are represented by Red Panda symbols!
