I think this is a 2010 map: the text on the back mentions awards gained in 2009, and the Nyala first arrived in 2009. It is a modified (and somewhat better-looking) version of the previous 2008 map, which in turn was a modified (and much worse-looking) version of the previous 2000 map).
There isn't much to say about this map.
The previous Meerkat enclosure now housed Leopard Tortoises, while the new Meerkat and Crested Porcupine enclosure is located further up past the Chimpanzees. (Interesting titbit: that former Meerkat enclosure was originally the elephant bath; however, somewhat sadly for a historic feature, that enclosure is long gone now).
The old elephant house which had been used for reptiles and fruit bats, had been turned into a tuck shop (a cafe), although there are still some reptile tanks alongside.
A Little Blue Penguin enclosure had been added near the zoo entrance (this enclosure no longer exists, and the penguins are housed elsewhere in the zoo).
