INTRODUCTION

Rotterdam, 6 April 2009 Never a dull moment with the EAZA Giraffe EEP. In 2008 we saw the results of the policy to phase out hybrid giraffes: the number decreased by 11 (6%) from 200 to 189, while the total number of giraffes increased from 525 to 554. Therefore the share of the hybrids decreased to 25% and the coming years a further and even more rapid decrease is expected as more and more hyrids are removed from breeding conditions. The population of Baringo giraffes increased again rapidly, the Reticulated and Kordofan giraffe population grew a bit more modest. So all in all the year 2008 saw the first results of all efforts done in the past years. The end of 2008 marked also the era of this species committee and in the beginning of 2009 new species committee elections were held. The EEP Coordinator and Studbook keeper (i.e. the undersigned) changed jobs again and EAZA decided, supported by the Giraffe & Antelope TAG, to move the coordination of this EEP with the present coordinator to Rotterdam Zoo. The EAZA Giraffe EEP is on the right way and achieving the goals the previous species committee had set itself half a decade ago. It can only be hoped that this development can be continued and accelerated with the next, newly elected species committee. The prospects for this are bright, as, despite the blue tongue, in 2008 over 100 giraffes were transported. This year, 2009, seems to beat that again. The Giraffe EEP again looks forward to a fruitful cooperation with all participants, in the interest of the giraffes and all institutions involved. Best regards, Marc Damen EAZA Giraffe EEP Coordinator Director / CEO, Rotterdam Zoo The Netherlands

Conservation activities:

The “Association pour la Sauvegarde des Girafes du Niger” (ASGN) tries to protect Nigerian giraffes (Giraffa camelopardalis peralta) and their habitat, while improving the wellbeing of the local people in Niger. This project is currently mainly supported by Doué-la-Fontaine/FR and Dalton-in-Furness/GB.

Research activities:

* Wildlife DNA Services, University of Wales, UK, is developing a suitable paternity test for giraffes. * Mitochondial DNA variability in Giraffa camelopardalis: consequences for taxonomy, phylogeography and conservation of giraffes in West and central Africa. Project of the National Museum of Natural History of Paris (which includes Paris zoo). * The Danish Cardiovascular Research Programme (DaGir) is studying the cardiovascular system of giraffes to better understand the humans cardiovascular system and diseases related to it.

History of the Giraffe EEP 1988: Established for Reticulated giraffes only. Co-ordinated by Dr. Anton Brotzler, Stuttgart.

1991: Decided to include all giraffes and to transform Reticulated giraffe EEP into Giraffe EEP.

1995: Dr. Anton Brotzler retired and was succeeded by Dr. Günther Schleußner from Stuttgart.

2003: The Giraffe EEP was split up into two separate EEPs: The Reticulated giraffe EEP included also the Masai giraffe and was co-ordinated by Dr. Günther Schleußner from Stuttgart. The Baringo giraffe EEP included all other giraffes and was co-ordinated by Ir. Marc Damen from Arnhem. Species committee elections were held.

2004: Meeting in Dvur Kralove to prepare husbandry guidelines.

Remarks on developments during 2008: The total population of giraffes included in the Giraffe EEP increased by only 3% (29 animals) till 754 animals. This is much lower than in 2007, when the EEP grew with 6% (46 giraffes). However, this is not as bad as it sounds at the first sight. In the first place a growth of 3% is enough to fill all additional spaces in the EEP; more important is that the reduced growth is mostly realised by a strong (6%) decrease in the population of hybrids; they now comprise ‘only’ 25% of the population; this was 27% at the end of 2007. Currently more measures are being undertaken to further slow down the reproduction of hybrids by actively placing as many hybrids as possible in single sex groups. This development is expected to continue and go faster in the future as more and more hybrids are being excluded from reproduction and placed in single sex groups. For that reason single sex groups of hybrids will be needed also in the near future. The number of institutions participating in the Giraffe EEP increased by six till 143 during 2008. Dresden/DE and Gdansk/PL started with an all male group, while Blackpool/GB and Ebeltoft/DK started keeping a group of hybrid females. Planckendael/BE is also a new participant; they received the breeding group of Antwerp but as part of the deal Antwerp received a hybrid female group as well. Tabernas / ES is a new member of EAZA and is keeping an all male group. No institutions gave up keeping giraffes. The EAZA Giraffe and Antelope TAG decided in 2003 to keep all subspecies of giraffes separated, although it could not be proved that Kordofan and Nigerian giraffes are two subspecies. During 2007 research proved that it are indeed two subspecies, but, more important, all so-called Nigerian giraffes turned out to be Kordofan giraffes, and this also applies to the crossbreeds of these two populations. The holders of giraffes of this subspecies and the Species Committee decided to accept the results of this scientific study and this was proposed to the EAZA Giraffe & Antelope TAG, who also accepted it. So from this moment on all former Nigerian giraffes, Kordofan giraffes as well as their crossbreeds are listed as Kordofan giraffes. Therefore the Giraffe EEP is split up into six groups:

A. The Kordofan giraffes B. The Southern giraffes (Cape and Angolan giraffes) C. The Masai giraffes D. The Reticulated giraffes E. The Baringo giraffes F. The hybrid giraffes and giraffes of unknown origin.

Age distribution As one can see on the age distribution printed below, it has a quite healthy ‘pyramid shape’. However, the number of females exceeds the number of males (297 males, 451 females), although slightly this is getting more equal. This can be declared by exports of males to non-EEP participants some years ago, as well as by the fact that male groups are in many cases being kept by less experienced institutions, and the mortality of giraffes is higher in new holders. The last years the number of males is increasing more rapidly than the number of females, due to the fact that no animals are allowed to leave the EEP.

Husbandry and management guidelines In 2006 husbandry and management guidelines were published. The guidelines are written by specialists, each in his or her own area of specialisation: Nutrition: Marcus Clauss, University of Zürich, Schwitzerland.

Jürgen Hummel, University of Bonn, Germany. Transport: Zdenek Barta, Dvur Králové, Czech Republic. Veterinary issues: Jacques Kaandorp, Hilvarenbeek, the Netherlands Husbandry: Ludek Culik, Dvur Králové, Czech Republic.

Waltraut Zimmermann, Köln, Germany. General items: Marc Damen, Arnhem, the Netherlands.

Günther Schleussner, Stuttgart, Germany. Kristina Tomasova, Dvur Králové, Czech Republic.

These guidelines were distributed to all participants in the Giraffe EEP in electronic form and also published on the member area of the EAZA website. They were amended by the Giraffe EEP Species Committee and therefore all participants in the Giraffe EEP are requested to follow these guidelines in the husbandry and management of giraffes. General actions for the year 2009 and later All pure giraffe females should be brought into a breeding situation as soon as possible; this means with a male of the same subspecies and without a male of another subspecies. More important is to further restrict the breeding of hybrid giraffes. The EEP is now slowly coming in the position that the production of pure giraffes can cope with the growth in spaces in the EEP; these additional places should be taken by pure giraffes only. The year 2009 will be mainly used to discuss with the new species committee if we can slowly put more restrictive measurements on the production of hybrids and to stop the production of hybrids. All of this needs to be done carefully to avoid empty giraffe enclosures. As already stated last year, we should avoid that hybrid males are in a breeding situation. In those exceptional cases where hybrid females are still breeding, they should do so with pure males. That way pure males can be ‘tested’ for their reproductive capabilities and in case there would be pure females available for this institution in the future, they already have a pure male. All hybrid males should be placed in bachelor groups. In new, inexperienced, institutions the mortality of giraffes turns out to be higher than in experienced institutions. This can be declared by the fact that the keepers and staff are less experienced with giraffes and the facilities have not yet been tested by giraffes. For that reason all new institutions have to start with a single sex group, either males, or hybrid females, to gain experience. Once gained positive experience and if females become available at a certain point, one could switch to a breeding group. It would not be fair if new institutions start with a breeding group, while others, who already gained experience and who followed the recommendations, have to stick to a bachelor group. Please be prepared to wait long before getting a breeding group of pure giraffes; there are already over 30 institutions waiting in line at the moment and please be aware we will always need single sex groups to control the development of the population. Still a few institutions are transporting giraffes without approval of the Giraffe EEP to non-EEP participants. As one can see on the next page, there are many alternative destinations within the Giraffe EEP. As in previous years, all transfers that have not been approved by the Giraffe EEP will have to be reported to the Antelope and Giraffe TAG, in the interest of the Giraffe EEP and the institutions who are cooperating.

Future holders So far, only one current member of EAZA, Montpellier/FR, will start keeping giraffes in 2009. They will start with a bachelor group of (maximum) four males. Furthermore several non-EAZA institutions are planning or building for giraffes. However, as EEPs are initiated for EAZA members and as our goal is to establish a sustainable population within EAZA, it will be clear that these non-EAZA institutions can not receive giraffes from the EAZA population for the time being. Especially if these institutions are situated within the EAZA region, the hybrid giraffe surplus will not be solved by sending them to non-EAZA institution, as these animals as well as their offspring, might return one day. The same happened years ago for example in the black-and-white ruffed lemur EEP (Varecia v. variegata). Several EAZA members showed interest to send girafes out of the EAZA region in exchange for other species. As the EAZA Giraffe EEP so far has had a ‘phase out’ policy for hybrids, this should be discussed with the new EAZA Giraffe Species Committee, which is elected in early 2009. If we can exchange giraffes with institutions in other regions for other EEP animals, and if these other EEPs are benefiting from this, this option should be seriously considered, also because it is sure that these giraffes will never return in the program because of veterinary restrictions. With the new species committee these proposals will be discussed, if at all giraffes can be made available, and if positive, which individuals for which goal, of course in cooperation and with permission of other EEPs.

Status and development of the European Studbook population Kordofan giraffes In 2007 a study proved that all giraffes in Europe formerly listed as Nigerian giraffes (Giraffa camelopardalis peralta), were in fact Kordofan giraffes (Giraffa camelopardalis antiquorum). Therefore both subpopulations were taken together in one Kordofan giraffe population, which now has a much brighter future in captivity. In 2008 the population of Kordofan giraffes did well in Europe. No less than ten (7.3) giraffes were born (1.0 DNS) and only three (2.1) died, resulting in a natural growth of 6 giraffes (10%). Ten giraffes (3.7) giraffes were transported between EAZA institutions; this includes also the complete group (1.4) of Antwerp Zoo, which was transported to Planckendael. Antwerp is now keeping a group of hybrid females. There is a lot of interest from institutions to start keeping this subspecies, like Dresden/DE and Montpellier/FR; both institutions will receive males for their bachelor group. As one can see, the population is doing well and despite the low number of founders (6) the prospects for this subspecies are not bad. Thanks to the fact that recently we could take together two groups of giraffes that were formerly kept separately as they were considered different subspecies, the gene diversity can increase considerably in the future. For this a strict management on EEP-level is required. With such a management this subspecies can survive in Europe. Genetic analysis for Kordofan giraffes End of

Cape giraffes Cape giraffes are being kept by nine participants; most of them are, although member of EAZA, quite isolated due to the distance to other EAZA members and the veterinary restrictions on transporting hoofstock to other regions of EAZA. During 2008 a total of seven (3.3.1) giraffes were born (1.1.1 DNS). Although the number of potential founders in the Cape giraffe population is high (the majority of the animals is still wildcaught and therefore potential founder), the prospects for this subspecies are not good. The institutions keeping this subspecies are scattered throughout all edges of Europe, from Moscow to Israel, from Dubai to the French coast. In 2008, apart from the neonatal death mentioned before, four more giraffes died. These giraffes are difficult to replace. Therefore it is clear that the future of this subspecies is uncertain for EAZA. There are four areas within the EAZA region where this subspecies is kept: the EU, Israel, Russia/Kazakhstan and the United Arab Emirates. All four regions can be considered as separate ‘isles’ as there are hardly possibilities to exchange giraffes. In Israel and the UAE this subspecies has a chance to survive a few generations if the institutions within these regions cooperate closely. Within the EU this subspecies has no chance, unless Bergamo joins the giraffe EEP and starts to cooperate closely. At this moment we do not really need the space occupied by Cape giraffes for other subspecies, but this subspecies is not promoted by the Giraffe EEP. Genetic analysis for Cape giraffes End of

Angolan giraffes The number of participants further decreased by one, as Neunkirchen lost their breeding male and the 2007 born female. Subsequently they sent their two adult females back to Dortmund. Now only Dortmund/DE and Estepona/ES and Lisbon/PT are keeping this subspecies. In 2008 three male offspring were born at Dortmund and Lisbon, making the population a bit less fragile. Since two years Lisbon and Dortmund try to exchange males, in order to continue breeding at both locations. This exchange is delayed because of veterinary (blue tongue) problems but is now likely to take place in spring 2009. A close cooperation between the three holders is absolutely necessary not to lose this subspecies in the next five years. But even with a good cooperation between the three institutions, the prospects for this subspecies are not good. Inbreeding is not high yet (7%), but will increase rapidly in the next generation. At the moment these giraffes are not taking spaces from other subspecies, but it can not be recommended to establish more breeding groups at the moment. The young males might be suitable for a bachelor group for educational purposes; surplus females should go to Estepona, to increase the number of giraffes there.

Masai giraffes With only 1.4 related Masai giraffes in two isolated sub-regions the Masai giraffe population will go extinct in the EAZA region. As far as known no Masai giraffes are being kept in non-EAZA institutions within the region. Exchanges between Schwitzerland and Israel are unlikely because of veterinary reasons; it also does not make much sense from a genetical point of view, as the male in Kiriat-Motzkin/IL is related to the Swiss females. Both institutions are keeping Masai giraffes only and by this they will also not produce hybrids. Basel Zoo tries to import a male from the North America or Japan, but chances for this are low. The EEP is following the developments but not taking an active approach in this matter. Genetic analysis for Masai giraffes End of

Reticulated giraffes In 2008 the population of Reticulated giraffes increased only by three individuals (3%), which is just the growth of the whole EEP (all subspecies including hybrids). As the hybrid population decreased, the growth in Reticulated giraffes is lower than in the other pure subspecies. This can be declared by the high death rate in 2008; no less than 14 giraffes died, but fortunately the majority were older males. Although the population did not grow as fast in the past year, and although the avarage inbreeding slightly increased and the gene diversity slightly decreased, this subspecies has a bright future. The number of females increased considerably, which is good for a faster growth of the population. In 2008 no less than 20 (9.11) Reticulated giraffes were born in 12 institutions, double the number of 2007 and the highest number of reticulated births ever. Three (2.1) neonates did not survive; this is only 15%. A total of 14 (7.7) giraffes were moved between EEP-participants and no Reticulated giraffes left the EEP. Fourteen (10.4) giraffes died in 11 institutions. Of the 33 institutions currently keeping this subspecies, 17 are keeping a breeding group, 15 are keeping only Reticulated giraffe males (either in a bachelor group or with hybrid females) and one institution is keeping only a female Reticulated giraffe without a male (a 27 year old female at St Petersburg).

Baringo Giraffes This subspecies comprises the biggest group in this EEP; 41% of all giraffes are Baringo giraffes. The population was growing rapidly in the past years and 2008 was no exception to this. Thanks to 46 births and 24 deaths the population increased by 8% (22 animals). A total of 46 (24.21.1) Baringo giraffes were born of which 9 (5.3.1) did not survive (20%). No less than 42 (26.16) animals were moved between EEP participants; these transports were all approved by the EEP. Sixteen (6.10) Baringo giraffes died. All of this caused a net increase of the population by 22 (13.9) giraffes. At the end of 2008 there were 308 (122.186) Baringo giraffes held at 72 institutions. Several institutions are still keeping a pure group plus some hybrid females. The first goal of the Giraffe EEP goal is to send these hybrid females to other places and replace them by pure females; for that reason the number of new holders of a breeding group will be restricted the coming years. The population is quite healthy, deriving from 44 founders, acquired from the wild in the early seventies. However, in those early days many Baringo giraffes, especially in safariparks, were mixed with giraffes of other subspecies; this seems to be especially the case in the United Kingdom. As a result of this, the subspecific status of several giraffes is doubtful. The EEP has to use a conservative approach: as long as the subspecific status is not completely cleared, it is considered to be as of unknown subspecific status. In the near future this especially needs to be discussed with several institutions on the British Isles, keeping one or two pure Baringo giraffes and also some hybrids. Some of them defenitely need to do a step back, in order for the whole EEP to further evoluate. This will be the challenge for the near future. Genetic analysis for Baringo giraffes End of

Hybrid Giraffes and Giraffes of unknown origin The major achievement in the giraffe EEP during 2008 was without doubt the decrease in the population of hybrid and unknown origin giraffes; this decreased by no less than 11 animals (6%)! This is the result of the strategy to place as many hybrids and unknown origin giraffes as possible outside breeding situations. In the past years the growth already slowed down and eventually also stopped, but 2008 is the year where the phasing out also can be seen in the figures. Still 28 (11.17) giraffes were born in this category, of which eleven (4.7) did not survive (39%). A total of 22 (6.16) were moved between EAZA institutions. Four giraffes (3.1) left the EEP. Finally 18 (4.14) hybrid and unknown origin giraffes died. It is tried to determine the subspecific status of the unknown origin giraffes to reduce their number. Furthermore it is the goal to phase out the hybrids by reducing their reproduction by establishing single sex groups. In 2005 for the first time the number of hybrid and unknown origin giraffes decreased. That could not be continued in 2006 and 2007, but the growth was in both years lower than the growth of the total population. In 2008 a net decrease was again realised. This is expected to continue and go faster in the years to come. In 2008 a lot of hybrids were placed in single sex groups in Antwerp/BE, Blackpool/GB, Dalton-in-Furness/GB, Ebeltoft/DK, Gdansk/PL, Lisieux/FR, Malton/GB, Peaugres/FR and Riga/LV and therefore less and less of these giraffes are in breeding situation. As at the moment the populations of Baringo giraffes, Reticulated giraffes and Kordofan giraffes are doing well and as the number of new holders is not increasing that fast anymore, we need to decrease the hybrid giraffe population as soon as possible, by removing as many hybrids as possible from a breeding situation and replace them by pure giraffes. It needs to be stated that the problem is a bit smaller than it seems, as several hybrid females are under birth control, like PZP.
