Hi Huntsman
I know Rhodes University only opened again this week. Rhodes has a brilliant Zoology department where you can study towards this - obviously it depends what you'd like to focus on. The Botany and Environmental Science departments have a joint honours in Conservation. If you email the departments directly with your queries I'm sure they'll give you a good idea of the options available. If you go onto the website
www.ru.ac.za/studentzone and then look under "Academic" and click on "Academic Departments" you'll find the Zoology, Environmental Science and Botany departments, all of which are either the best or within the top few best in the country - definitely worth a look.
I'm in the Environmental Science department and have just started my PhD, not in conservation, but in ecosystem services focusing on designing a statistical model to better understand the complex social, economic and ecological relationships in South Africa - something which is vital in making decisions pertaining to many environmental issues across South Africa.
So there are many focus angles available to a simply question/degree. And many are worth a snoop around!
If you have any other questions please feel free to ask
