摘要
The Tanzania-Zambia highway crosses Mikumi National Park over a stretch of 50 km. The road was rehabilitated between May 1990-November 1991 resulting in higher average driving speeds. Data were collected on the incidence of road kills of animals within the park boundaries during this period. The list of 183 mammals, birds and reptiles killed by vehicles included at least 52 species, two of which are endangered: the African elephant (Loxodonta africana Blumenbach) and the African hunting dog (Lycaon pictus Temminck). The road-kill rate increased and was estimated at a minimum of three road kills per day (218 road kills/km/yr) by the end of the study. Road kills were more frequent near water holes and traditionally used animal tracks. The demographic effect of road kills on troops of yellow baboons (Papio cynocephalus Linnaeus), which include the highway in their ranges, is in the order of 10% of the total yearly losses. High speed and the danger of collisions with wildlife are causing regular accidents in Mikumi National Park. Adequate signposts along the road and speed bumps are recommended in order to reduce the average driving speeds for the sake of humans and wildlife.
