International International studbook for Grevy's zebra ... - Marwell Zoo

Introduction
Introduction
Welcome to the most recent edition of the International studbook for Grevy’s zebra. It has been another
eventful year and you can find information on developments in the field followed by status and changes
throughout 2010 in the zoo world on the following pages.
I would like to thank all of you for cooperating with the studbook and the breeding programmes for the
benefit of this wonderful species.
PLEASE, WOULD ALL REGISTRARS (HOLDERS AND OWNERS) ENTER THE PERMANENT STUDBOOK NUMBERS IN
THEIR RECORDS TO MAKE FUTURE COMMUNICATION ABOUT INDIVIDUAL ANIMALS EASIER. THANK YOU!
Captive Captive Population:
Population:
The total number of Grevy's Zebra in captivity as reported to the studbook keeper by 31 st December 2010
was 188.303.0 (491) in 114 institutions. Of this 91.148.0 (239) in 52 institutions are in the EEP. This is
based on the last known information from each institution up to that time.
An annual breakdown of births and deaths during 2010 is as follows:

Identification:
With the advances in digital technology it is now easier than ever to take photos of your Grevy’s zebra and
send them to the international studbook coordinator. A large database for these pictures is already in place,
but many photos are still outstanding. The correct recording of a photo in one central location (with the
studbook keeper) has several benefits:
1. It safeguards your zebra’s identity, even if a transponder has been lost.
2. It allows the identification of animals which were sent out of coordinated programmes like the SSP or
EEP and reported as lost-to-follow-up, and are potentially re-entering those programmes at a later
stage.
3. In some countries and regions, it is now necessary to have individual passports for wild equids. A
complete set of specimen report, pedigree and identification photo can be provided by the studbook
keeper, if all photos are recorded with her.
I would therefore urge you all to provide digital photos to the studbook where possible. If you are unsure if
you have sent photos to the studbook keeper already, please do not hesitate to ask.

EEP African Equids Husbandry Guidelines, edited by Ulrike Rademacher and Achim Winkler, were

Wild Wild Status:
Status:
The IUCN Red Data Book 2009 lists Grevy's zebra as Endangered A2ac; C2a(i);assessed 2008 by
Moehlman, P.D., Rubenstein, D.I. & Kebede, F. Justification: Listed as Endangered as Grevy's Zebra is
estimated to have declined by more than 50% over the past 18 years based on direct observation and
potential/actual levels of exploitation. In addition, the current total population is estimated at 750 mature
individuals, with the largest subpopulation estimated at 255 mature individuals. Listed on CITES Appendix I,
Grevy's Zebra are legally protected in Ethiopia, although official protection has been limited. Communitybased
conservation has been more effective. In Kenya, they have been protected by a hunting ban since
1977. While under the Wildlife Conservation and Management Act No 376 of 1976 (Part II of the First
Schedule), Grévy’s Zebra was listed as a ‘Game Animal’ (Williams 2002); they are currently being uplisted
to a legally ‘Protected Animal’ in Kenya. (Moehlman, P.D., Rubenstein, D.I. & Kebede, F. 2008).
