We saw bay, Peters,' and blue duikers, and much sign of the big yellowback duiker, but Jason didn't have time and I'd had these from previous safaris.
Blue duikers dropped 26 per cent; larger red duikers 42 per cent; and yellow-backed duikers 59 per cent.
Three species were very abundant: (1) blue duikers ([delta] = 0.315 signs/km), (2) red river hogs ([delta] = 0.19 signs/km), and (3) bay duikers ([delta] = 0.155 signs/km).
Of that meat, nearly three-quarters, by weight, came from hoofed animals such as antelopes called bay and blue duikers. However, the list also includes aardvarks, horny-scaled anteaters called pangolins, and 22 species of primates.
"The numbers are just huge," Bennett says, especially when hoofed animals are taken into account: WCS estimates that 28 million bay duikers are killed annually, as are 16 million blue duikers. "And these are conservative figures." The problem has reached such tremendous proportions that last summer, at a meeting of gorilla experts in Germany, scientists from WCS and other institutions said that poaching has surpassed habitat loss as the most immediate threat facing western lowland gorillas, and could lead to their extinction in the next 20 years.
