M<strong>on</strong>itoring and management priorities<br />
Our observati<strong>on</strong>s suggest that <strong>the</strong> current distributi<strong>on</strong> of <strong>the</strong> <strong>Bale</strong> M<strong>on</strong>key is closely associated<br />
with <strong>the</strong> bamboo and mixed-bamboo forest. This forest type occurs <strong>on</strong> very steep slopes that are<br />
dissected by steep ravines, making it very difficult for humans to access in an extensive way. Local<br />
people harvest bamboo as a subsistence crop but <strong>the</strong>re is also some commercial harvest around Rira<br />
(Tesfaye this editi<strong>on</strong>). One priority for m<strong>on</strong>itoring is <strong>the</strong>refore to assess <strong>the</strong> extent and quality of<br />
<strong>the</strong> bamboo and mixed-bamboo forest. Remotely sensed data may play an important role, given <strong>the</strong><br />
difficulty of access to <strong>the</strong>se habitats for field surveys or m<strong>on</strong>itoring. Management priorities may<br />
include <strong>the</strong> regulati<strong>on</strong> of <strong>the</strong> level of bamboo harvesting (Tesfaye this editi<strong>on</strong>), or at least restricting<br />
commercial activities within <strong>the</strong> park. The locati<strong>on</strong> of settlements and agricultural fields may also<br />
need to be c<strong>on</strong>sidered in terms of <strong>the</strong> implicati<strong>on</strong>s for <strong>the</strong> <strong>Bale</strong> m<strong>on</strong>key and its habitat.<br />
Finally, additi<strong>on</strong>al surveys in <strong>the</strong> locality are necessary to improve <strong>the</strong> estimate of <strong>the</strong><br />
populati<strong>on</strong> density and abundance. There are o<strong>the</strong>r stands of bamboo within <strong>Bale</strong> <strong>Mountains</strong><br />
Nati<strong>on</strong>al park and its surroundings where <strong>Bale</strong> m<strong>on</strong>keys have been recorded. Additi<strong>on</strong>al sampling<br />
in <strong>the</strong>se areas would be helpful for establishing a better understanding of <strong>the</strong> species distributi<strong>on</strong>.<br />

The authors are grateful to <strong>the</strong> Oromia Bureau and <strong>the</strong> <strong>Bale</strong> <strong>Mountains</strong> Nati<strong>on</strong>al Park for permissi<strong>on</strong><br />
to work in <strong>the</strong> Harenna Forest. Mr Addisu Assefa provided helpful informati<strong>on</strong> about <strong>the</strong> m<strong>on</strong>key and<br />
<strong>the</strong> bamboo forest, as well as logistical support. The Frankfurt Zoological Society <strong>Bale</strong> <strong>Mountains</strong><br />
C<strong>on</strong>servati<strong>on</strong> Project, in particular, Deborah Randall and Alastair Nels<strong>on</strong>, also provided logistical<br />
support and encouragement to publish <strong>the</strong> manuscript. The field work was supported by Hussen<br />
Batu, Mohamed Batu and Aliyu. Wildlife C<strong>on</strong>servati<strong>on</strong> Department (now, <strong>the</strong> Ethiopian Wildlife<br />
C<strong>on</strong>servati<strong>on</strong> Authority) and <strong>the</strong> Darwin Initiative (DEFRA, UK) provided financial support. Mr.<br />
Fanuel Kebede helped with <strong>the</strong> survey and o<strong>the</strong>r aspects of <strong>the</strong> project. Two an<strong>on</strong>ymous reviewers<br />
and Deb Randall provided helpful comments <strong>on</strong> an earlier draft of <strong>the</strong> manuscript.<br />
