title: [Biogeographical distribution of snakes in Cameroon: the case of venomous snakes].
abstract: A preliminary analysis of the distribution of snakes captured in Cameroon between 1999 and 2004 is presented in this study. This work helps to provide a better understanding of the distribution of the venomous snakes. The main focus of this study was to identify regions of high diversity of venomous species, a useful step towards developing a national strategy of snakebite care and antivenom distribution. We recorded 4,910 specimens of 150 species from 361 localities throughout Cameroon. Among the ten provinces in Cameroon, the southwest province recorded the highest number of venomous snakes. Diversity was less in the far-north province, but the high abundance of Echis ocellatus seems to be responsible for many snake bites in the region. Of all venomous snakes, the forest cobra Naja melanoleuca was the most abundant in the forest region. The humid savannah region was dominated by Causus maculatus while the Sahelian part by Echis ocellatus. Given the abundance and high snake bite cases of the latter in the region, snakebite care from a national point of view should begin from the far-north towards the forest region of the south-west Cameroon.
