Not having seen your text, (of course) I can't say whether the "perturbations observées" are all negative. However, I would not "coupe de bois" to denote coppicing.

The talk about coupe de bois in the table presumably meaning wood cutting, so I thought this should be different. Coppicing seems possible, although from my initial quick look, coppicing is supposed to be good for biodiversity. I suppose a human disruption doesn't always have to be negative.

I could be wrong (happens a lot), but I still think that pressure on the forest is the key... Take a look at this PDF, ETUDE DE L’OFFRE ET DE LA DEMANDE SUR LE BOIS ET SES PRODUITS DERIVES, http://www.cciampnr.com/docs/etude_offre_demande_bois.pdf
Good luck!

I had something like this at the back of my mind. You can sort of visualize lots of village structures based on some kind of plant cut for poles. I am less sure about the culling idea. None of the documents I have discusses fish resources, but in general the area is highly anthropized and considered resource poor by general Congo standards, so enough fish to need culling seems unlikely. Other than that, there is not much guidance from the text.

I suppose this is the other "perch" possibility: http://en.wikipedia.org/wiki/Nile_perch
IMOl, more to do with fishing than with brush fires, hunting or slash-and-burn farming. ;-)
But perhaps Colin Morley has the key... Let your text be your guide.

I don't know if that fits with the "cueillette" part, which I am reading as "gathering". They talk about traditional food gathering practices elsewhere. It sounds to me like they are cutting some kind of something to be used for some definite purpose, but really I am just guessing. The table appears at the end of the document, and the word "perche" does not appear anywhere else.

Could it be that trees in which the animals were accustomed to perching or sheltering were cut down or otherwise destroyed by hunters, farmers or slashers-and-burners?
