L’Hoest’s monkey (Allochrocebus lhoesti) is vulnerable mountain monkey whose population trends decrease throughout its natural habitat. Their vulnerability caused by various threats like hunting, fragmentation and roadkill mortality. However, information about the effect on road to the population of L’hoest’s monkey is limited and therefore the conservation decisions are poorly informed.

This study is aimed at assessing the effects of the road to the population of L’hoest’s monkey through investigating the factors attract them to the road, extent of roadkill mortality due to collision with vehicles and investigating how the road affect activities and behavioral patterns of A. lhoesti. The combination of systematic sampling and simple random sampling will be applied in data collection. Set of data like roadkill animals, activity and behavioral patterns of Allochrocebus lhoesti as well as site covariates will be collected during the field work while set of packages in Rstudio will be putting together for analysis and interpretations through Generalized Linear Mixed Models (GLMMs).

The results of this project will provide information about the factors influencing mountain monkeys to be threatened with the road which increase their roadkill mortality; To raise conservation awareness of A. lhoesti and other primate species as well as mammals using the continued road in NNP as well as to develop initiative of warning the road users to be aware and inform park management decision makers.
