I personally would like to see the zoo become more specialised within its collection by building up on either its cats, canid or primate collection.
Or maybe develop a collection of species that are unusal and seldom seen within other UK zoos to set it apart from the rest. Similar to RSCC.
I think considering as its almost looked up to as the head of the zoos in the country, that it is falling behind from other collections like chester for example and the plans that bristol have. What the place needs is a large injection of cash. I think the rainforest life and gorilla enclosure are a step in the right direction but they need to do something on a much bigger and larger scale.
Imagine what its like for tourists paying £20 to get into the world famous London zoo to see no elephants, bears, chimps, orangs, rhino and etc that most foreign zoos have. What they need to do is to combat this possible dissapointment by creating a better quality of enclosure and collection that provides a unique as well as a more immersive experience. Otherwsie i dont know where the zoo is heading really.
