It's a sign of the current situation at Jersey- they need it run as a business more to clear their debts etc.
I do not fully agree: A zoo is not equal to a business, you can not merely see plants and wildlife in a zoo as mere product(s).
Just aka Jersey Zoo should balance its books better while still generating good cash for its world reknowned in situ conservation programmes for "small" (as in non mega (in)vertebrates) endangered species and up its attendance figures while yet generating much more funds for upgrading its exhibits within the zoo.
I do hope they succeed (obviously their location on Jersey does not help!). What really infuriates me about Jersey Zoo is that this overtly rich island nation fails its world reknowned zoo miserably (in seems like decadence of the bourgeousie and gentry before the French revolution over there!). So many rich folks and not many care to give a few bucks for their zoo! A nation that does not cherish and support its heritage, is not worth the salt of the earth methinks!
