Ah but Mazo, do you know why this is?
It's because primates (gorillas especially) are very susceptible to human diseases. They only have to be within a relatively short range of human feces and they can contract a virus relatively quickly and almost always die when they do. Their immune system cannot tolerate what a human being can. Fossey fired several staff who refused to take this seriously...so in that sense, there was definitely some logic to WHY she was doing what she did...but perhaps not so much in HOW she was doing it.

The virulence and infection rate varies between primates but I agree with your basic premise that we share diseases with them and that the gorillas should be protected from infection with agents that aren't native or common to them.
What I don't agree with is your logic about how that serves as a reason to evict indigenous populations from a gorilla habitat. Humans and gorillas sharing that territory would have been equally exposed over the years to the same illnesses and would have developed equivalent immunity to them. The
indigenous peoples who were displaced would not have posed an infection threat to the gorillas.
What
does pose an threat are western tourists who bring in viruses that are not typical of that region. For instance, respiratory syncytial virus - a virus that leads to respiratory "colds" and is a common cause of pneumonia - is normally only a problem in equatorial regions during the rainy summer months. In temperate latitudes, though, you see much more RSV problems during the winter (our "cold and flu season"). The serotypes of the virus found in temperate climates are also different from those found in equatorial Africa. That means tourists are going to be carrying in RSV serotypes that the gorillas have less immunity to and are doing it at the time of year when they are not normally being exposed.
And RSV is just one isolated example. There are numerous infectious agents that are common in northern latitudes that you don't see at the equator. The risks are far greater than just minor agents like RSV.
If the Fund is really concerned about this as a threat then they are doing exactly the opposite of what they should be. The native population doesn't pose any real risk because, while they may serve as a reservoir of virus that could infect the gorillas, they also are carrying the viruses the gorillas will already have developed innate immunity to. Furthermore, the native people don't get near the gorillas so there's minimal chance of infection in the first place.
Not so with the Fund. They march as many western tourists through the preserve as they can every year and those tourists get right up in the face of the animals. If a gorilla is going to die from an exotic disease then chances are they're going to have caught it from a tourist, not a native pygmy.
So I agree that this is a potential problem, but it's also one more example of how the Fund is not following Fossey's legacy. As you noted, Dian was extremely picky about who got close to the animals. These days the Fund is hooked up with a private safari company that leads groups of tourists into the preserve to get as close to the animals as they can. You can just pop on their website and sign up. Dian's original intent may have been to protect the animals from disease. Now days that's been abandoned in the name of fund raising.
On a related note, one thing Fossey never stood for was holding animals in captivity. The Fund is now doing just that. They've built a "rehab center" for gorillas with funds put up by The Disney Company. Gorillas that are rescued from poachers are now sent to the center rather than being returned to the wild population. At the center they are in constant contact with humans - yet another thing that Dian herself would never have stood for. There are rumors that Disney paid for the project in exchange for rights to bring some of the animals back to the theme parks for display. That hasn't happened yet, but Disney put up a good chunk of change for the work. We'll have to see exactly what they got for their money.
Sorry to drone on about this but as you can tell I really, really despise what these people are doing. They're pretty much working against the core principles that every other conservation movement uses. I think that it's a sad state of affairs but money talks in Rwanda and the Fund has the government's ear. Until somebody with more cash can muscle them out we're stuck with whatever the Fund wants to do. It's really frustrating to the science community to see it happening this way.
Cheers,
Mazo.
