We saw three white rhino. The Game Preservation Officer estimated the number of these animals in the park at about 100 and said that improvements in the park should ensure their continued existence there. Considering the smallness of the area of the Nimule Park, the number of square-lipped rhino is amazingly high.
Dehorning operations in Zimbabwe. The key measure of interest in horn regrowth is the mass and, hence, monetary value of the horns. Converting measurements into mass values, we found that adult males (n = 38) carried an average mass of 6,24 kg while females (n = 45) supported 5,10 kg before horn removal. Over 90% of the horn was removed from adult males and over 93% from females. Based on regrowth measured in the first year, mean annual mass produced by adults is 0,56 kg and 0,45 kg for males and females, respectively.
