Abstract
Wildlife conservation is essential, especially for countries like Kenya which
rely on tourism as a major earner of foreign exchange. Conservation of species
with minimal ecological information such as Grevy’s zebra, though a chal-
lenge, is critical to enable the future survival of such species. Grevy’s and
Plains zebra have been classified as endangered and near-threatened by Inter-
national Union for Conservation of Nature and Natural Resources (IUCN)
respectively, with Grevy’s zebra found mostly in Northern Kenya and Ethi-
opia. This has been due to habitat degradation from livestock grazing, local
hunting and development of resorts. Six prediction variables i.e. rainfall, tem-
perature, land use, population, NDVI and cattle occurrence were used in
Maxent algorithm to produce a habitat prediction map for both species. Both
prediction maps had an AUC > 0.75, which is adequate for conservation plan-
ning. Niche similarity based on Warren’s I index (I = 0.78) indicates that both
zebra species are identical based on their occupied niche environments, sug-
gesting that similar conversation strategies can be adopted for both species.

1. Introduction
Global tourism has experienced continued growth, accompanied with deepening
diversification, to become one of the fastest growing economic sectors in the
world, contributing 10.2% of global GDP in 2016. In Kenya, it contributed 9.8%
of Kenya’s GDP in 2016, accounting for 9.2% of total employment in Kenya [1].
Tourism in Kenya is mainly wildlife-based, with the big five large mammals
(elephant, rhino, buffalo, lion and leopard) being the main source of tourism sa-
tisfaction and revenue [2]. However, tourist’s preference on the big five has led
