NPR listening
Summary:

2 years ago scientists from the New York base research society made a new discovery. In the republic of Congo in Africa, almost 125,000 gorillas were estimated to be inhabitants in the western lowlands. According to Steve Sanderson, Ceo/Pres. of Wildlife Conservation Society, "this estimation counts for more than twice the number of gorillas thought to be living in Africa." From listening to the recording the original estimated number was between 50,000-100,000 populations around Africa.
I wondered why these gorillas haven’t been agitated by poachers, other people, or even diseases. I found out that the reason for this is because the areas that these gorillas are living in are wet, swampy lowlands that are almost impossible to live for humans. The only way to travel through that area is through swamps, slippery surfaces, etc. which can become close to impractical to do. Therefore the gorillas have been able to thrive without poachers, or diseases brought in by humans, which is the usual cause for extinction in most parts of the world that once have gorillas roaming the land.
I would like to know about how they traveled through the difficult lands to their new discovery, and how long did it take for them to make such an estimation?
