Numbers of this isolated subspecies have undergone a severe decline. Very small remnant populations survive in the Aberdares, Mount Kenya, Mau Forest and Eburu Forest. Current estimates (2007) suggest a total of 75-140 individuals, well below the threshold of 250 mature individuals. The taxon is still declining and none of the subpopulations listed above contains 50 mature individuals. The lower population estimate would also qualify for Critically Endangered under criterion D.
