At each location two or three trails of varying lengths (750 m to 2700 m) were used for lemur surveys. We utilized preexisting trails left by bush pigs, cows and humans, as well as newly cut and laid out trails. Lemurs were censused by walking slowly (approximately km h ') along trails marked at 25 m cumulative intervals with flagging tape. Diurnal samples took place at times of increased lemu

We utilized preexisting trails left by bush pigs, cows and humans, as well as newly cut and laid out trails. Lemurs were censused by walking slowly (approximately km h ') along trails marked at 25 m cumulative intervals with flagging tape. Diurnal samples took place at times of increased lemur activity, in the morning (6:00 - 12:30h) and in the afternoon (15:00 - 18:00 h). Walks were always separated by a time interval of at least six hours when trails were censused twice during daylight hours. Nocturnal censuses commenced 10 to 30 minutes after dusk for two to four hours each night. The dim light of a headlamp was used at night to pick up the eyeshine from the reflective tapetum of nocturnal lemurs. Once detected, a more powerful hand-held flashlight and binoculars (7x40) were used for species Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Bonn, Zoologisches Forschungsinstitut und Museum Alexander Koenig
