My original plan was to observe behavior in groups of crowned lemurs and Sanford's lemurs, but in a sacred forest fragment where I had seen them last year. That plan got scrapped when a sport hunter removed one of the species from that site. I then went to a forest fragment that was not sacred, but which has both species.
I just got back yesterday afternoon. Two issues surfaced immediately:
1) Both species act much differently from how they behave in the good large forest where I did my doctoral dissertation work. In fact, this new forest fragment is pretty small (maybe 100 hectares... a hectare is 100meters by 100 meters), but was the subject of EXTENSIVE logging in the 1980's. This means that it is very dense with smaller trees, bushes, and tangles. But it also means that people have been moving their farmland nearby, creating even more damage. So what appears as 100 hectares is actually no more than about 50 hectares, most of which is forest edge. WHAT THIS MEANS is that it is nearly impossible to follow these species without trails that mirror their home ranges, and I had no hope of having such trails put in during my stay.
2) The lemurs get up at 4-ish, and the crowned lemurs start traveling around 512AM... and they travel fast and long. Hard to follow the same group for more than a few minutes if you HAVE NO LIGHT, especially in dense cover. The Sanford's were somewhat easier to follow, but would also be difficult to follow sans trails.
So, I decided to bug out. Three months would be okay for the site, if it was just the one site, but that was not in the offing this year.
Having said that, I was able to talk more at length with local people about their use of and interaction with the forest, and THAT can (and will) be written up. SO, I was partially successful in my stay at the site. I hope that trails get put in, so that I can study these lemurs, but given the pressing issues of the area, I wonder just how much longer that site will continue to exist. While I was following one group, I encountered a bush fire beside their home range. And clearly, a lot of banana plantations are going up, even in the last two years.
But people view these lemurs and the forest in ways that are very surprising. Although many people have no fady (tradition or taboo) against the taking of the lemurs, most people hold these lemurs as something different from the rest of the forest animals. When I asked people to name 5 forest animals, lemurs rarely came up. However, everyone could say something about them, and the language was metaphoric. No folklore, no fady, but something more. I have to do some more work on this, but I believe they don't view them completely as animals, but as something else. More details on this as I get some translations verified.
If you think this is kind of strange, consider that in the US, one of the more difficult things to teach in biology is the concept of humans as part of a group of biological organisms that includes primates. In some cases, it's tough to teach that humans are biological organisms. It tends to go against many people's beliefs. Belief systems are powerful things.
Maybe what's going on here in Madagascar are belief systems that hold these lemurs as something (nearly) identical to humans. And for the lemurs' conservation, that may be a bit of good news to come from this work, even in an unprotected forest fragment.
