Warthogs, waterbucks, hartebeests and gazelles are among animals whose population is declining due to construction of roads, offices and residential houses close to Nairobi National Park .
A newly published National Wildlife Census 2021 report by the Tourism and Wildlife ministry shows the populations of these animals have declined by about 70 percent amid pressure from infrastructure development, real estate and pollution in bordering residential areas such as Kitengela and the Athi-Kapiti plains.
