Are there any breeding groups in other parts of the world? Exchanging young males could bring in new bloodlines.
Not afaik. The last ones in the USA were imported to Europe some years ago I believe- three females went to Marwell to form a group with an Edinburgh-bred male but their stay was brief and they never bred there. I don't think there are any in Zoos outside Europe now. Interesting that in the 1990's there were five collections in the UK alone that housed them.
