That's right. I didn't find mention of the Loch Lomond population still bring extant. I have a feeling the Scottish Island population is somewhat maintained by the landowner, if I remember correctly.
At no time did I say, or infer, that any wallaby born in the 1950s would be alive today! I may be old, but I am not yet mentally infirm. I lived and worked in that area, before Whipsnade was constructed. There has been sightings of wallabies quite often in Bedfordshire and surrounding counties over many years. Sorry you have not heard of them, and good luck with your speculations. I have no doubt that animals have escaped from Whipsnade, from time to time, and I believe that most have either been killed or have simply died, but it is likely that some may have survived. In UK there were many species kept privately before there were regulations to prevent this. A Black bear cub was handed into a Police station in Surrey, in about 1962.
if the date of birth on your profile is accurate, you were born nine years after Whipsnade opened, almost to the day!My mistake, TL Dave, I thought Whipsnade was opened in the late 1950s. Some of my memories are not as good as they used to be!!You're not *that* old
