Studying primate population, behavior, and human primate interaction is important for planning conservation and management actions. Human-wildlife conflict is any form of interaction that results direct or indirect cost to humans and wildlife. This study was conducted in and around Taragedam Forest from November 2022 to May 2023. The objective of this study was to estimate the population size of grivet monkeys using the total count method, to examine their time budget using instantaneous scan sampling, and to examine the extent of human-grivet conflict using questionnaire interview in Taragedam Forest. The largest number of grivet monkey is juveniles followed by adult females. There was significant difference in the number of grivet monkeys in terms of their habitats where the largest number of grivet monkeys were found in the forest and followed by shrub land. Grivet monkeys spent 45.7% feeding, 19.7% moving, 18.6% grooming, 10.5% resting, 5.0% socialization, and 0.5% others in their diurnal activity budget. The local people used various crop control methods: scarecrow, sling, guarding, tying dogs, and fences, snap trapping, and remove proxy trees to farmlands. Most respondents had negative attitude towards the conservation of grivet monkey there was statistical significance difference in wildlife conservation with respect to villager’s educational status. Educated individuals had positive view towards wildlife conservation than illiterate. Rapid population growth, habitat destruction, and expansion of agriculture were the major threats to the study area. Awareness creation should be done to the community about environmental and ecological values of the area. Keywords: Activity time budget, Conflict, Grivet monkeys, Population size, Taragedam Forest.
