A site comparison study in 2015 in a forest in Oregon, USA (Curtis & Du Toit 2017) found that closing roads to traffic during the hunting season increased use of those areas by mule deer Odocoilius hemionus. Mule deer positions were closer to closed roads (average 190 m) than to open roads (average 1,250 m). In March 2015, an unspecified number of mule deer were captured and fitted with GPS collars that recorded their location every 13 hours. Deer locations and distances to the nearest road were recorded in August–October 2015. During this period, an unspecified number of roads in the area were closed to vehicles, while others remained open. This period overlapped with the legal hunting season.
