INTRODUCTION<br />

Rotterdam, 6 April 2009<br />

Never a dull moment with <strong>the</strong> EAZA Giraffe EEP. In 2008 we saw <strong>the</strong> results of <strong>the</strong> policy to<br />

phase out hybrid <strong>giraffe</strong>s: <strong>the</strong> number decreased by 11 (6%) from 200 to 189, while <strong>the</strong> total<br />

number of <strong>giraffe</strong>s increased from 525 to 554. There<strong>for</strong>e <strong>the</strong> share of <strong>the</strong> hybrids decreased to<br />

25% and <strong>the</strong> coming years a fur<strong>the</strong>r and even more rapid decrease is expected as more and<br />

more hyrids are removed from breeding conditions.<br />

The population of Baringo <strong>giraffe</strong>s increased again rapidly, <strong>the</strong> Reticulated and Kordofan<br />

<strong>giraffe</strong> population grew a bit more modest. So all in all <strong>the</strong> year 2008 saw <strong>the</strong> first results of<br />

all ef<strong>for</strong>ts done in <strong>the</strong> past years.<br />

The end of 2008 marked also <strong>the</strong> era of this species committee and in <strong>the</strong> beginning of 2009<br />

new species committee elections were held. The EEP Coordinator and Studbook k<strong>eep</strong>er (i.e.<br />

<strong>the</strong> undersigned) changed jobs again and EAZA decided, supported by <strong>the</strong> Giraffe &<br />

Antelope TAG, to move <strong>the</strong> coordination of this EEP with <strong>the</strong> present coordinator to<br />

Rotterdam Zoo.<br />

The EAZA Giraffe EEP is on <strong>the</strong> right way and achieving <strong>the</strong> goals <strong>the</strong> previous species<br />

committee had set itself half a decade ago. It can only be hoped that this development can be<br />

continued and accelerated with <strong>the</strong> next, newly elected species committee.<br />

The prospects <strong>for</strong> this are bright, as, despite <strong>the</strong> blue tongue, in 2008 over 100 <strong>giraffe</strong>s were<br />

transported. This year, 2009, seems to beat that again.<br />

The Giraffe EEP again looks <strong>for</strong>ward to a fruitful cooperation with all participants, in <strong>the</strong><br />

interest of <strong>the</strong> <strong>giraffe</strong>s and all institutions involved.<br />

Best regards,<br />

Marc Damen<br />

The “Association pour la Sauvegarde des Girafes du<br />

Niger” (ASGN) tries to protect Nigerian <strong>giraffe</strong>s (Giraffa<br />

camelopardalis peralta) and <strong>the</strong>ir habitat, while<br />

improving <strong>the</strong> wellbeing of <strong>the</strong> local people in Niger.<br />

This project is currently mainly supported by Doué-la-<br />

Fontaine/FR and Dalton-in-Furness/GB.<br />

Research activities:<br />

Remarks on developments during 2008:<br />

The total population of <strong>giraffe</strong>s included in <strong>the</strong> Giraffe EEP increased by only 3% (29 animals) till<br />

754 animals. This is much lower than in 2007, when <strong>the</strong> EEP grew with 6% (46 <strong>giraffe</strong>s).<br />

However, this is not as bad as it sounds at <strong>the</strong> first sight. In <strong>the</strong> first place a growth of 3% is<br />

enough to fill all additional spaces in <strong>the</strong> EEP; more important is that <strong>the</strong> reduced growth is mostly<br />

realised by a strong (6%) decrease in <strong>the</strong> population of hybrids; <strong>the</strong>y now comprise ‘only’ 25% of<br />

<strong>the</strong> population; this was 27% at <strong>the</strong> end of 2007. Currently more measures are being undertaken<br />

to fur<strong>the</strong>r slow down <strong>the</strong> reproduction of hybrids by actively placing as many hybrids as possible<br />

in single sex groups. This development is expected to continue and go faster in <strong>the</strong> future as more<br />

and more hybrids are being excluded from reproduction and placed in single sex groups. For that<br />

reason single sex groups of hybrids will be needed also in <strong>the</strong> near future.<br />

The number of institutions participating in <strong>the</strong> Giraffe EEP increased by six till 143 during 2008.<br />

Dresden/DE and Gdansk/PL started with an all male group, while Blackpool/GB and Ebeltoft/DK<br />

started k<strong>eep</strong>ing a group of hybrid females. Planckendael/BE is also a new participant; <strong>the</strong>y<br />

received <strong>the</strong> breeding group of Antwerp but as part of <strong>the</strong> deal Antwerp received a hybrid female<br />

group as well. Tabernas / ES is a new member of EAZA and is k<strong>eep</strong>ing an all male group. No<br />

institutions gave up k<strong>eep</strong>ing <strong>giraffe</strong>s.<br />

The EAZA Giraffe and Antelope TAG decided in 2003 to k<strong>eep</strong> all subspecies of <strong>giraffe</strong>s<br />

separated, although it could not be proved that Kordofan and Nigerian <strong>giraffe</strong>s are two subspecies.<br />

During 2007 research proved that it are indeed two subspecies, but, more important, all so-called<br />

Nigerian <strong>giraffe</strong>s turned out to be Kordofan <strong>giraffe</strong>s, and this also applies to <strong>the</strong> crossbreeds of<br />

<strong>the</strong>se two populations. The holders of <strong>giraffe</strong>s of this subspecies and <strong>the</strong> Species Committee<br />

decided to accept <strong>the</strong> results of this scientific study and this was proposed to <strong>the</strong> EAZA Giraffe &<br />

Antelope TAG, who also accepted it. So from this moment on all <strong>for</strong>mer Nigerian <strong>giraffe</strong>s,<br />

Kordofan <strong>giraffe</strong>s as well as <strong>the</strong>ir crossbreeds are listed as Kordofan <strong>giraffe</strong>s.<br />

There<strong>for</strong>e <strong>the</strong> Giraffe EEP is split up into six groups:<br />

A. The Kordofan <strong>giraffe</strong>s<br />

B. The Sou<strong>the</strong>rn <strong>giraffe</strong>s (Cape and Angolan <strong>giraffe</strong>s)<br />

C. The Masai <strong>giraffe</strong>s<br />

D. The Reticulated <strong>giraffe</strong>s<br />

E. The Baringo <strong>giraffe</strong>s<br />

F. The hybrid <strong>giraffe</strong>s and <strong>giraffe</strong>s of unknown origin.<br />

Age distribution<br />

As one can see on <strong>the</strong> age distribution printed below, it has a quite healthy ‘pyramid shape’.<br />

However, <strong>the</strong> number of females exceeds <strong>the</strong> number of males (297 males, 451 females), although<br />

slightly this is getting more equal. This can be declared by exports of males to non-EEP<br />

participants some years ago, as well as by <strong>the</strong> fact that male groups are in many cases being kept<br />

by less experienced institutions, and <strong>the</strong> mortality of <strong>giraffe</strong>s is higher in new holders. The last<br />

years <strong>the</strong> number of males is increasing more rapidly than <strong>the</strong> number of females, due to <strong>the</strong> fact<br />

that no animals are allowed to leave <strong>the</strong> EEP.<br />

Husbandry and management guidelines<br />

In 2006 husbandry and management guidelines were published. The guidelines are written by<br />

specialists, each in his or her own area of specialisation:<br />

Kristina Tomasova, Dvur Králové, Czech Republic.<br />

These guidelines were distributed to all participants in <strong>the</strong> Giraffe EEP in electronic <strong>for</strong>m and also<br />

published on <strong>the</strong> member area of <strong>the</strong> EAZA website. They were amended by <strong>the</strong> Giraffe EEP<br />

Species Committee and <strong>the</strong>re<strong>for</strong>e all participants in <strong>the</strong> Giraffe EEP are requested to follow <strong>the</strong>se<br />

guidelines in <strong>the</strong> husbandry and management of <strong>giraffe</strong>s.<br />

General actions <strong>for</strong> <strong>the</strong> year 2009 and later<br />

All pure <strong>giraffe</strong> females should be brought into a breeding situation as soon as possible; this<br />

means with a male of <strong>the</strong> same subspecies and without a male of ano<strong>the</strong>r subspecies.<br />

More important is to fur<strong>the</strong>r restrict <strong>the</strong> breeding of hybrid <strong>giraffe</strong>s. The EEP is now slowly<br />

coming in <strong>the</strong> position that <strong>the</strong> production of pure <strong>giraffe</strong>s can cope with <strong>the</strong> growth in spaces in<br />

<strong>the</strong> EEP; <strong>the</strong>se additional places should be taken by pure <strong>giraffe</strong>s only. The year 2009 will be<br />

mainly used to discuss with <strong>the</strong> new species committee if we can slowly put more restrictive<br />

measurements on <strong>the</strong> production of hybrids and to stop <strong>the</strong> production of hybrids. All of this needs<br />

to be done carefully to avoid empty <strong>giraffe</strong> enclosures.<br />

As already stated last year, we should avoid that hybrid males are in a breeding situation. In those<br />

exceptional cases where hybrid females are still breeding, <strong>the</strong>y should do so with pure males. That<br />

way pure males can be ‘tested’ <strong>for</strong> <strong>the</strong>ir reproductive capabilities and in case <strong>the</strong>re would be pure<br />

females available <strong>for</strong> this institution in <strong>the</strong> future, <strong>the</strong>y already have a pure male. All hybrid males<br />

should be placed in bachelor groups.<br />

In new, inexperienced, institutions <strong>the</strong> mortality of <strong>giraffe</strong>s turns out to be higher than in<br />

experienced institutions. This can be declared by <strong>the</strong> fact that <strong>the</strong> k<strong>eep</strong>ers and staff are less<br />

experienced with <strong>giraffe</strong>s and <strong>the</strong> facilities have not yet been tested by <strong>giraffe</strong>s. For that reason all<br />

new institutions have to start with a single sex group, ei<strong>the</strong>r males, or hybrid females, to gain<br />

experience. Once gained positive experience and if females become available at a certain point,<br />

one could switch to a breeding group. It would not be fair if new institutions start with a breeding<br />

group, while o<strong>the</strong>rs, who already gained experience and who followed <strong>the</strong> recommendations, have<br />

to stick to a bachelor group. Please be prepared to wait long be<strong>for</strong>e getting a breeding group of<br />

pure <strong>giraffe</strong>s; <strong>the</strong>re are already over 30 institutions waiting in line at <strong>the</strong> moment and please be<br />

aware we will always need single sex groups to control <strong>the</strong> development of <strong>the</strong> population.<br />

Still a few institutions are transporting <strong>giraffe</strong>s without approval of <strong>the</strong> Giraffe EEP to non-EEP<br />

participants. As one can see on <strong>the</strong> next page, <strong>the</strong>re are many alternative destinations within <strong>the</strong><br />

Giraffe EEP. As in previous years, all transfers that have not been approved by <strong>the</strong> Giraffe EEP<br />

will have to be reported to <strong>the</strong> Antelope and Giraffe TAG, in <strong>the</strong> interest of <strong>the</strong> Giraffe EEP and<br />

<strong>the</strong> institutions who are cooperating.<br />

Future holders<br />

So far, only one current member of EAZA, Montpellier/FR, will start k<strong>eep</strong>ing <strong>giraffe</strong>s in 2009.<br />

They will start with a bachelor group of (maximum) four males.<br />

Fur<strong>the</strong>rmore several non-EAZA institutions are planning or building <strong>for</strong> <strong>giraffe</strong>s. However, as<br />

EEPs are initiated <strong>for</strong> EAZA members and as our goal is to establish a sustainable population<br />

within EAZA, it will be clear that <strong>the</strong>se non-EAZA institutions can not receive <strong>giraffe</strong>s from <strong>the</strong><br />

EAZA population <strong>for</strong> <strong>the</strong> time being. Especially if <strong>the</strong>se institutions are situated within <strong>the</strong> EAZA<br />

region, <strong>the</strong> hybrid <strong>giraffe</strong> surplus will not be solved by sending <strong>the</strong>m to non-EAZA institution, as<br />

<strong>the</strong>se animals as well as <strong>the</strong>ir offspring, might return one day. The same happened years ago <strong>for</strong><br />

example in <strong>the</strong> black-and-white ruffed lemur EEP (Varecia v. variegata).<br />

Several EAZA members showed interest to send girafes out of <strong>the</strong> EAZA region in exchange <strong>for</strong><br />

o<strong>the</strong>r species. As <strong>the</strong> EAZA Giraffe EEP so far has had a ‘phase out’ policy <strong>for</strong> hybrids, this<br />

should be discussed with <strong>the</strong> new EAZA Giraffe Species Committee, which is elected in early<br />

2009. If we can exchange <strong>giraffe</strong>s with institutions in o<strong>the</strong>r regions <strong>for</strong> o<strong>the</strong>r EEP animals, and if<br />

<strong>the</strong>se o<strong>the</strong>r EEPs are benefiting from this, this option should be seriously considered, also because<br />

it is sure that <strong>the</strong>se <strong>giraffe</strong>s will never return in <strong>the</strong> program because of veterinary restrictions.<br />

With <strong>the</strong> new species committee <strong>the</strong>se proposals will be discussed, if at all <strong>giraffe</strong>s can be made<br />

available, and if positive, which individuals <strong>for</strong> which goal, of course in cooperation and with<br />

permission of o<strong>the</strong>r EEPs.<br />

Status and development of <strong>the</strong> <strong>European</strong> Studbook population<br />

Kordofan <strong>giraffe</strong>s<br />

In 2007 a study proved that all <strong>giraffe</strong>s in Europe <strong>for</strong>merly listed as Nigerian <strong>giraffe</strong>s (Giraffa<br />

camelopardalis peralta), were in fact Kordofan <strong>giraffe</strong>s (Giraffa camelopardalis antiquorum).<br />

There<strong>for</strong>e both subpopulations were taken toge<strong>the</strong>r in one Kordofan <strong>giraffe</strong> population, which now<br />

has a much brighter future in captivity.<br />

In 2008 <strong>the</strong> population of Kordofan <strong>giraffe</strong>s did well in Europe. No less than ten (7.3) <strong>giraffe</strong>s<br />

were born (1.0 DNS) and only three (2.1) died, resulting in a natural growth of 6 <strong>giraffe</strong>s (10%).<br />

Ten <strong>giraffe</strong>s (3.7) <strong>giraffe</strong>s were transported between EAZA institutions; this includes also <strong>the</strong><br />

complete group (1.4) of Antwerp Zoo, which was transported to Planckendael. Antwerp is now<br />

k<strong>eep</strong>ing a group of hybrid females. There is a lot of interest from institutions to start k<strong>eep</strong>ing this<br />

subspecies, like Dresden/DE and Montpellier/FR; both institutions will receive males <strong>for</strong> <strong>the</strong>ir<br />

bachelor group.<br />

As one can see, <strong>the</strong> population is doing well and despite <strong>the</strong> low number of founders (6) <strong>the</strong><br />

prospects <strong>for</strong> this subspecies are not bad. Thanks to <strong>the</strong> fact that recently we could take toge<strong>the</strong>r<br />

two groups of <strong>giraffe</strong>s that were <strong>for</strong>merly kept separately as <strong>the</strong>y were considered different<br />

subspecies, <strong>the</strong> gene diversity can increase considerably in <strong>the</strong> future. For this a strict management<br />

on EEP-level is required. With such a management this subspecies can survive in Europe.<br />

Cape <strong>giraffe</strong>s<br />

Cape <strong>giraffe</strong>s are being kept by nine participants; most of <strong>the</strong>m are, although member of EAZA, quite<br />

isolated due to <strong>the</strong> distance to o<strong>the</strong>r EAZA members and <strong>the</strong> veterinary restrictions on transporting<br />

hoofstock to o<strong>the</strong>r regions of EAZA.<br />

During 2008 a total of seven (3.3.1) <strong>giraffe</strong>s were born (1.1.1 DNS). Although <strong>the</strong> number of potential<br />

founders in <strong>the</strong> Cape <strong>giraffe</strong> population is high (<strong>the</strong> majority of <strong>the</strong> animals is still wildcaught and<br />

<strong>the</strong>re<strong>for</strong>e potential founder), <strong>the</strong> prospects <strong>for</strong> this subspecies are not good. The institutions k<strong>eep</strong>ing<br />

this subspecies are scattered throughout all edges of Europe, from Moscow to Israel, from Dubai to<br />

<strong>the</strong> French coast.<br />

In 2008, apart from <strong>the</strong> neonatal death mentioned be<strong>for</strong>e, four more <strong>giraffe</strong>s died. These <strong>giraffe</strong>s are<br />

difficult to replace. There<strong>for</strong>e it is clear that <strong>the</strong> future of this subspecies is uncertain <strong>for</strong> EAZA. There<br />

are four areas within <strong>the</strong> EAZA region where this subspecies is kept: <strong>the</strong> EU, Israel,<br />

Russia/Kazakhstan and <strong>the</strong> United Arab Emirates. All four regions can be considered as separate<br />

‘isles’ as <strong>the</strong>re are hardly possibilities to exchange <strong>giraffe</strong>s. In Israel and <strong>the</strong> UAE this subspecies has<br />

a chance to survive a few generations if <strong>the</strong> institutions within <strong>the</strong>se regions cooperate closely. Within<br />

<strong>the</strong> EU this subspecies has no chance, unless Bergamo joins <strong>the</strong> <strong>giraffe</strong> EEP and starts to cooperate<br />

closely. At this moment we do not really need <strong>the</strong> space occupied by Cape <strong>giraffe</strong>s <strong>for</strong> o<strong>the</strong>r<br />

subspecies, but this subspecies is not promoted by <strong>the</strong> Giraffe EEP.<br />

Angolan <strong>giraffe</strong>s<br />

The number of participants fur<strong>the</strong>r decreased by one, as Neunkirchen lost <strong>the</strong>ir breeding male and <strong>the</strong><br />

2007 born female. Subsequently <strong>the</strong>y sent <strong>the</strong>ir two adult females back to Dortmund. Now only<br />

Dortmund/DE and Estepona/ES and Lisbon/PT are k<strong>eep</strong>ing this subspecies. In 2008 three male<br />

offspring were born at Dortmund and Lisbon, making <strong>the</strong> population a bit less fragile.<br />

Since two years Lisbon and Dortmund try to exchange males, in order to continue breeding at both<br />

locations. This exchange is delayed because of veterinary (blue tongue) problems but is now likely to<br />

take place in spring 2009.<br />

A close cooperation between <strong>the</strong> three holders is absolutely necessary not to lose this subspecies in<br />

<strong>the</strong> next five years. But even with a good cooperation between <strong>the</strong> three institutions, <strong>the</strong> prospects <strong>for</strong><br />

this subspecies are not good. Inbreeding is not high yet (7%), but will increase rapidly in <strong>the</strong> next<br />

generation. At <strong>the</strong> moment <strong>the</strong>se <strong>giraffe</strong>s are not taking spaces from o<strong>the</strong>r subspecies, but it can not be<br />

recommended to establish more breeding groups at <strong>the</strong> moment. The young males might be suitable<br />

<strong>for</strong> a bachelor group <strong>for</strong> educational purposes; surplus females should go to Estepona, to increase <strong>the</strong><br />

number of <strong>giraffe</strong>s <strong>the</strong>re.<br />

Masai <strong>giraffe</strong>s<br />

With only 1.4 related Masai <strong>giraffe</strong>s in two isolated sub-regions <strong>the</strong> Masai <strong>giraffe</strong> population will go<br />

extinct in <strong>the</strong> EAZA region. As far as known no Masai <strong>giraffe</strong>s are being kept in non-EAZA<br />

institutions within <strong>the</strong> region. Exchanges between Schwitzerland and Israel are unlikely because of<br />

veterinary reasons; it also does not make much sense from a genetical point of view, as <strong>the</strong> male in<br />

Kiriat-Motzkin/IL is related to <strong>the</strong> Swiss females. Both institutions are k<strong>eep</strong>ing Masai <strong>giraffe</strong>s only<br />

and by this <strong>the</strong>y will also not produce hybrids. Basel Zoo tries to import a male from <strong>the</strong> North<br />

America or Japan, but chances <strong>for</strong> this are low. The EEP is following <strong>the</strong> developments but not taking<br />

an active approach in this matter.<br />

Reticulated <strong>giraffe</strong>s<br />

In 2008 <strong>the</strong> population of Reticulated <strong>giraffe</strong>s increased only by three individuals (3%), which is just<br />

<strong>the</strong> growth of <strong>the</strong> whole EEP (all subspecies including hybrids). As <strong>the</strong> hybrid population decreased,<br />

<strong>the</strong> growth in Reticulated <strong>giraffe</strong>s is lower than in <strong>the</strong> o<strong>the</strong>r pure subspecies. This can be declared by<br />

<strong>the</strong> high death rate in 2008; no less than 14 <strong>giraffe</strong>s died, but <strong>for</strong>tunately <strong>the</strong> majority were older<br />

males. Although <strong>the</strong> population did not grow as fast in <strong>the</strong> past year, and although <strong>the</strong> avarage<br />

inbreeding slightly increased and <strong>the</strong> gene diversity slightly decreased, this subspecies has a bright<br />

future. The number of females increased considerably, which is good <strong>for</strong> a faster growth of <strong>the</strong><br />

population.<br />

In 2008 no less than 20 (9.11) Reticulated <strong>giraffe</strong>s were born in 12 institutions, double <strong>the</strong> number of<br />

2007 and <strong>the</strong> highest number of reticulated births ever. Three (2.1) neonates did not survive; this is<br />

only 15%. A total of 14 (7.7) <strong>giraffe</strong>s were moved between EEP-participants and no Reticulated<br />

<strong>giraffe</strong>s left <strong>the</strong> EEP. Fourteen (10.4) <strong>giraffe</strong>s died in 11 institutions.<br />

Of <strong>the</strong> 33 institutions currently k<strong>eep</strong>ing this subspecies, 17 are k<strong>eep</strong>ing a breeding group, 15 are<br />

k<strong>eep</strong>ing only Reticulated <strong>giraffe</strong> males (ei<strong>the</strong>r in a bachelor group or with hybrid females) and one<br />

institution is k<strong>eep</strong>ing only a female Reticulated <strong>giraffe</strong> without a male (a 27 year old female at St<br />

Petersburg).<br />

Baringo Giraffes<br />

This subspecies comprises <strong>the</strong> biggest group in this EEP; 41% of all <strong>giraffe</strong>s are Baringo <strong>giraffe</strong>s. The<br />

population was growing rapidly in <strong>the</strong> past years and 2008 was no exception to this. Thanks to 46<br />

births and 24 deaths <strong>the</strong> population increased by 8% (22 animals).<br />

A total of 46 (24.21.1) Baringo <strong>giraffe</strong>s were born of which 9 (5.3.1) did not survive (20%).<br />

No less than 42 (26.16) animals were moved between EEP participants; <strong>the</strong>se transports were all<br />

approved by <strong>the</strong> EEP. Sixteen (6.10) Baringo <strong>giraffe</strong>s died. All of this caused a net increase of <strong>the</strong><br />

population by 22 (13.9) <strong>giraffe</strong>s. At <strong>the</strong> end of 2008 <strong>the</strong>re were 308 (122.186) Baringo <strong>giraffe</strong>s held at<br />

72 institutions.<br />

Several institutions are still k<strong>eep</strong>ing a pure group plus some hybrid females. The first goal of <strong>the</strong><br />

Giraffe EEP goal is to send <strong>the</strong>se hybrid females to o<strong>the</strong>r places and replace <strong>the</strong>m by pure females; <strong>for</strong><br />

that reason <strong>the</strong> number of new holders of a breeding group will be restricted <strong>the</strong> coming years.<br />

The population is quite healthy, deriving from 44 founders, acquired from <strong>the</strong> wild in <strong>the</strong> early<br />

seventies. However, in those early days many Baringo <strong>giraffe</strong>s, especially in safariparks, were mixed<br />

with <strong>giraffe</strong>s of o<strong>the</strong>r subspecies; this seems to be especially <strong>the</strong> case in <strong>the</strong> United Kingdom. As a<br />

result of this, <strong>the</strong> subspecific status of several <strong>giraffe</strong>s is doubtful. The EEP has to use a conservative<br />

approach: as long as <strong>the</strong> subspecific status is not completely cleared, it is considered to be as of<br />

unknown subspecific status. In <strong>the</strong> near future this especially needs to be discussed with several<br />

institutions on <strong>the</strong> British Isles, k<strong>eep</strong>ing one or two pure Baringo <strong>giraffe</strong>s and also some hybrids.<br />

Some of <strong>the</strong>m defenitely need to do a step back, in order <strong>for</strong> <strong>the</strong> whole EEP to fur<strong>the</strong>r evoluate. This<br />

will be <strong>the</strong> challenge <strong>for</strong> <strong>the</strong> near future.<br />

Hybrid Giraffes and Giraffes of unknown origin<br />

The major achievement in <strong>the</strong> <strong>giraffe</strong> EEP during 2008 was without doubt <strong>the</strong> decrease in <strong>the</strong><br />

population of hybrid and unknown origin <strong>giraffe</strong>s; this decreased by no less than 11 animals (6%)!<br />

This is <strong>the</strong> result of <strong>the</strong> strategy to place as many hybrids and unknown origin <strong>giraffe</strong>s as possible<br />

outside breeding situations. In <strong>the</strong> past years <strong>the</strong> growth already slowed down and eventually also<br />

stopped, but 2008 is <strong>the</strong> year where <strong>the</strong> phasing out also can be seen in <strong>the</strong> figures.<br />

Still 28 (11.17) <strong>giraffe</strong>s were born in this category, of which eleven (4.7) did not survive (39%). A<br />

total of 22 (6.16) were moved between EAZA institutions. Four <strong>giraffe</strong>s (3.1) left <strong>the</strong> EEP. Finally 18<br />

(4.14) hybrid and unknown origin <strong>giraffe</strong>s died.<br />

It is tried to determine <strong>the</strong> subspecific status of <strong>the</strong> unknown origin <strong>giraffe</strong>s to reduce <strong>the</strong>ir number.<br />

Fur<strong>the</strong>rmore it is <strong>the</strong> goal to phase out <strong>the</strong> hybrids by reducing <strong>the</strong>ir reproduction by establishing<br />

single sex groups. In 2005 <strong>for</strong> <strong>the</strong> first time <strong>the</strong> number of hybrid and unknown origin <strong>giraffe</strong>s<br />

decreased. That could not be continued in 2006 and 2007, but <strong>the</strong> growth was in both years lower than<br />

<strong>the</strong> growth of <strong>the</strong> total population. In 2008 a net decrease was again realised. This is expected to<br />

continue and go faster in <strong>the</strong> years to come. In 2008 a lot of hybrids were placed in single sex groups<br />

in Antwerp/BE, Blackpool/GB, Dalton-in-Furness/GB, Ebeltoft/DK, Gdansk/PL, Lisieux/FR,<br />

Malton/GB, Peaugres/FR and Riga/LV and <strong>the</strong>re<strong>for</strong>e less and less of <strong>the</strong>se <strong>giraffe</strong>s are in breeding<br />

situation.<br />

As at <strong>the</strong> moment <strong>the</strong> populations of Baringo <strong>giraffe</strong>s, Reticulated <strong>giraffe</strong>s and Kordofan <strong>giraffe</strong>s are<br />

doing well and as <strong>the</strong> number of new holders is not increasing that fast anymore, we need to decrease<br />

<strong>the</strong> hybrid <strong>giraffe</strong> population as soon as possible, by removing as many hybrids as possible from a<br />

breeding situation and replace <strong>the</strong>m by pure <strong>giraffe</strong>s. It needs to be stated that <strong>the</strong> problem is a bit<br />

smaller than it seems, as several hybrid females are under birth control, like PZP.<br />
