This seems a little harsh to me, top 10 I can understand but top 20? What 20 zoos would you say are better?
Other zoochatters beat me to that. There was a number of threads in this forum about top zoos, top exhibits etc., and London is always out or far down in rankings. Even if with some wishful thinking one says that London zoo is the 15th best zoo in the country, it is remains a third-league zoo which wasted its history and enormous potential.
London Zoo has enormous potential because of potential donors nearby in the London Financial City, which very few zoos in the world have. It should have been full of world-class exhibits and animals like Zurich Zoo.
And when was Colchester constructed.
This discussion seems to suffer from comparing only with nearby English zoos, while most people know other city zoos abroad. That is why only somebody with an experience from abroad can revitalize this institution.
It would be interesting to compare today London Zoo against good historic city zoos abroad: Basel, Antwerp, Vienna, Cologne, Leipzig, Berlin zoo, Zurich, Paris zoos, Amsterdam, Rotterdam, some Czech zoos and so on. One could compare size, historic buildings, large and smaller animals and exhibits. It might be a good thread for Zoochat. It should show opportunities for London.
because they don't house elephants (eg) at London is not a fair comparison
It is not about one species or exhibit. It is about the absence of the most and mediocre average.
Other city zoos usually set space for some very large animals. Of smaller animals, London zoo still could have a bear species, sealions, other apes besides gorillas, further smaller primates, mid-sized cats, some smaller active herding ungulate like a mountain goat species or sitatunga, and a big aquarium, reptile and small mammal buildings.
White Elephant House could be readily converted for smaller animals, possibly with changing moats to glass walls or net aviaries. The Lubetkin Pool could be a children play area. Or become enclosed inside an aviary or an enclosure. It might be a decent decoration or a climbing structure.
Re: Regent's Park's listed buildings, it is worth pointing out that successive Mayors of London have allowed the demolition of multiple listed or historic buildings within London
If a building allegedly poses life hazard from chunks of concrete falling on people's heads, like Mappin / aquarium, this is a really strong argument to pull down a historic structure. Especially that this huge steel and concrete structure was build without regard how it would be repaired.
This is the question how actively London zoo tries to change?
