But gone are the days of zoos being able to pay their keepers next to nothing because, essentially, it was possible to live on next to nothing if you loved your job, whereas nowadays, you can't do that because property everywhere is overpriced, especially rental, and so Marwell has clearly been on a journey of marketability over the last couple of decades, and I don't think it would have survived had it not done this.
I would love there to be a way a park comprised essentially of paddocks and wood/wire enclosures in parkland and woodland housing rare ungulates and carnivores could have survived into the present day, however even Howletts and Port Lympne, funded by the once mighty casinos, have had to 'develop' to attract more gate revenue and additional spend.
Colchester, as an example given by someone else on this thread, was not a particularly attractive site to walk round.....I think development at place like Marwell and Port Lympne always risk detracting from the character of those places, given that so much of it is provided by the trees and topography.
I do think that Marwell needed its penguins, it needed its tropical house, but it had the perfect natural woodland for an open-topped gibbon/anoa/otter exhibit, which could have been constructed at less cost, and I hope over time Marwell will open up and combine its paddock system (now that the African Valley is open), move its primates into the woods, and not attempt to convert an open field into an expensive gorilla exhibit. But we shall see...
