I certainly did and I have many nostalgic memories from that period and, yes, the collection was exciting then in a way that it could not be today. Memory tends to recall the good and not necessarily the facts and I stand by my observation that Marwell still has a significant collection of antelope and zebras. Checking back 40 years (1981) Marwell had 3 species of zebra and 12 species of antelope; it still holds 3 species of zebra and 12 species of antelope. Regarding mammals, there were then 65 species then (including 5 domestic, so 60 wild species) and today still has 60 species. But the bird collection is now notably smaller than it was, with just two thirds of the species (56 in 1981, 40 today) that were kept in 1981, perhaps surprising considering the number added in recent years with the opening of the walk-through aviary and the tropical house.
The big change though is in the number of individual mammals, from about 450 in the early 1980s to around 190 today, and I think this is the main reason why people recall Marwell having a more diverse collection than it had. There are many valid reasons why the numbers of individuals has changed but these are certainly not unique to Marwell; an interesting and complex topic but one, perhaps for more general discussion in another forum?
