Feral Domestic
Horses closed
membership
Grevy’s Zebras
Asiatic Wild Asses
African Wild Asses
open
membership
Why does it matter?
- Wandering males
don’t protect females
& young
-50% lion scat contain
only Grevy’s hair
(Lewa: GZ only 25%)
II. Grevy’s Don’t like Black Cotton Soil
Why does it matter?
Poor performance = Hybrids
III. Some Laikipia Zebra Populations
are Declining
Theoretical Populations
Actual Populations
Ol Pejeta Conservancy PZ
Hotspotter IDs
Lewa GZ
Borana PZ
Mpala GZ & PZ
Ol Jogi GZ
Why does it matter?
New approach
needed for
balancing
species at risk
