     Despite presumed abundance and widespread distribution, limited data exist on the status of the longtailed macaque (Macaca fascicularis) population in Indonesia. In 2009, we conducted a preliminary survey of M. fasciculars on Java to assess their distribution and the increasing reports of human-primate conflict. As a follow-up, we conducted a more thorough survey of the island during 3-17 March and 16-25 October 2012, covering 8,079km. Travel and observation occurred from 7am until 8pm daily and involved the use of secondary roads to allow for frequent stops to query local people regarding the presence/absence of M. fasciculars. Over the 25-day survey period, we visited 78 sites across Java with reported or confirmed monkey sightings (national parks, nature reserves, agricultural areas, local tourist sites). Reports of human-primate conflict were noted at 54 of the 78 sites and typically involved various forms of crop raiding or stealing food. The average reported population size was 67.9 monkeys (range: 5-450). Also striking was the vast area with reports of “no monkeys here.” These macaque populations are often located in areas of human habitation, where sightings and conflict occur frequently, and may lead to assumptions of over-abundance in regions where actual population size is much smaller then perceived.
