By Will Knocker:
C. t. albojubatus (Eastern White-bearded Wildebeest), of which species the IUCN says: “ However, recent population estimates suggest that the future prospect of some subpopulations or subspecies is of some concern, particularly that of the Eastern White-bearded Wildebeest (which, it seems, may have undergone a precipitous decline in numbers).”
Hope for the future? A yearling (born March 2012)……
This species was once one of the most numerous herbivores wandering the vast high plains of the Athi Kapiti Ecosystem of which NNP is the last remaining pristine corner: it has been estimated that there were 100,000 at the beginning of the Twentieth century.
Now: ”Eastern White-bearded Wildebeest, 94,000 (with about two-thirds in and around protected areas)”, of which we in NNP have about one hundred & fifty individuals (144 counted in February game count).
‘Our’ gnus tend to live on the rapidly dwindling Sheep & Goat Land between the park & the ever-burgeoning New Town of Kitengela south of the Park, which is heavily grazed short-grass plain habitat. The question must be: will they move into the Park once this last stronghold goes the way of the rest of the ecosystem?
The majority of the gnus in the Athi Kapiti live south of the Athi-Namanga highway, which they cannot cross to get to the Park. These will find it difficult to survive in an increasingly humanised & truncated ecosystem .

Our last few Eastern White-bearded gnus, for whom the Nairobi National Park is their last refuge…..
