Large carnivores are known to adjust their activity in relation to humans. A general way for carnivores to avoid humans is to become more nocturnal. Thus, their “night life” increases as human activity does. Given that the density of roads is a good proxy for human disturbance, researchers from the Scandinavian Brown Bear Research Project have found out that bears moved most in the nocturnal and twilight hours and less during daytime in those areas with higher road density, compared to roadless areas. The link to the paper HERE. The authors suggest to limit the building and use of roads in order to maintain a high quality habitat for large carnivores. A similar proposal was done in the Management Plan for the Brown Bear in Poland, where the few remaining roadless areas in the Polish Carpathians were recommended to be maintained road-free, and thus, free of human disturbance.
