Common warthog (Phacochoerus africanus) occur throughout Namibia except the far south, southeast, arid west (i.e., Namib Desert), and the densely populated northcentral communal areas. Their Namibian conservation and legal status lists warthog as "secure and huntable game" (Griffin & Coetzee, 2005). Although seemingly ubiquitous, often alongside major roads where they are viewed as a nuisance to drivers, little has been published regarding their local ecology and/or numbers. During 2013, Namibia experienced a widespread drought with warthog lured to road verges with better grazing. Their numbers seemed astounding at times - e.g. 391 individuals on a 146 km stretch of the B1 highway between Okahandja and Otjiwarongo in central Namibia on 7 October 2013 between 17h00 and 19h00 (this study). Mean average annual rainfall for this area varies from 300 mm in the south (Okahandja area) to 450 mm in the north (Otjiwarongo area) mainly between January and April. Coefficient of variation in rainfall of 3040% (Mendelsohn et al., 2002) mainly between January and April. During the 2012/2013 rainy season these areas received between 100 and 200 mm. Whilst travelling this route for other purposes, I kept note of warthog numbers along this section of the B1 Highway, including anthropomorphic activities potentially affecting warthog distribution. This note highlights some of these findings and although not attempted as a formal scientific study it does raise interesting questions.
