Editor, I do agree with  Sam, but it looks like you forgot to mention "research”. Even Dian Fossey was doing research on gorillas, and all that she discovered form the roots as you mentioned. Applying for a research permit is rather problematic.

There should be facilitation or collaborations. There is a very strong relationship between research, conservation and tourism.Brigitte N SwedenReaction to Sam Kebongo’s commentary, "How much do you know abou about the gorilla, the rose and its roots?”, (The New Times, April 6)
