Hilgert’s vervet monkey (Chlorocebus pygerythrus hilgerti)
Altitude range: 1700 – 2100 m
Main habitats: Yellow fever Acacia xanthophloea woodland along Sinyai Lugga, Timau River and larger dams.
Percentage of Lolldaiga used: 5 – 10%
Group size: 7 – 30
Abundance as of May 2015: 200 – 300 individuals
Other information: Elephant numbers on Lolldaiga are high (>300 individuals) and increasing. Elephants are now causing considerable damage to the yellow fever tree woodlands. This is expected to result in a decline in Lolldaiga’s population of vervets.
