I believe it was not much different than it was today. More so that some species' enclosures were of different animals [i.e. coatis as opposed to red panda; sun conure as opposed to swift parrot...] the wallaby area [Aussie Bushwalk] was smaller than it is now, and its nearby aviary, which held kookaburra, held various species over the years - for sometime it had hornbills, but in most recent times it had wonga pigeons and blue-faced honeyeaters - the latter of which remains at Marwell, but the former since moved on.
It was only called 'Fur Feathers and Scales' as of 2013 when the erstwhile-coati enclosure was built - prior to that it was 'Encounter Village', where it had a black rat enclosure as well as a tamarin walkthrough for a few years. Itself an area redeveloped and opened in 2007 - before that further it was a petting farm with domestic animals. The farmyard would close sometime shortly before Knowles' retirement in 2006.
