History

General history

Sofia Zoo's history goes way back. Bulgaria, at least the original territories it partly encompasses, was once part of the Turkish Ottoman Empire. After the war between Russia and the Turkish Empire, Bulgaria gained some degree of independence in 1878. When Prince Ferdinand Saxe-Coburg-Gotha - an amateur ornithologist and keen nature lover with scientific interest who spent a lot of time in the field collecting animals and plants - became head of state in 1888 he assigned by decree a site for a zoological garden in the royal botanical garden, at the time a former city dump on the outskirts of town but nowadays near Borysova gardens. The new site was necessary because the small animal collection created by Prince Ferdinand, with its centrepiece the birdcage holding a black vulture next to common pheasants, red deer and a pair of brown bears, became too large to be maintained in the garden of the royal palace of Vrana. Nonetheless, 1888 can be regarded as the year Sofia Zoo was founded, which makes it the oldest zoo in the Balkans.

Thus, in 1890, the royal zoological garden was established on the edge of the city. In addition to the animals of the existing collection, otters, wild goats, lama, birds of prey, swans and cranes were accommodated in the new 2.4 ha facilities. Keepers were appointed, and a sculptor, Ernst Hublein, was called from Coburg especially to take on the job of supervisor. Besides sculptor, Hublein was a keen taxidermist. And his skill to stuff the zoo animals that died, laid the foundation of the National Museum of Natural History, originally named the Royal Prince 's Natural History Museum. This tradition to stuff the rare and more valuable animals from Sofia Zoo still continues.

In 1892, the Zoo's animal collection was extended with a pair of African lions, which were purchased from Leipzig Zoo by Hublein. Already that same year the lions procreated and the cow barn had to be turned into a temporary lion enclosure. Until 1893 the animals in the Zoo could only be admired by the royal family and their guests. However, interest in the animals housed in the zoological garden grew among Sofia citizens, and in the summer of 1893 the gardens were opened to the common people. At first only for three days a week, but free of charge. The species collection became more and more varied, and besides the lions, dromedary camels, elk (Cervus canadensis) and Barbary sheep were acquired. At the same time - under the new manager, ornithologist Paul Leverkühn, who also headed the staff of the National Museum of Natural History - buildings and other enclosures were constructed. Pheasants house 1894Perhaps the most important of these constructions were the elongated aviary with 24 separate cages for pheasants and other gallinaceous birds, and the large domed aviary for bearded vultures, griffon vultures and black vultures. The Zoo successfully bred the bearded vultures, producing 13 offspring with a single pair of adult birds in about 20 years. This achievement, unique at the time when nowhere else this bird was bred in captivity, brought great respect from the zoological community. From then on Sofia Zoo was considered a serious scientific zoological institution. Other important milestones during the management of Leverkühn were the new bear houseBear house 1894, carnivore houseCarnivores house 1894 and the first pool for waterfowl, including pelicans, black swans, ducks and geese.

At the end of the 19th century the zoo collection had already an impressive 1,384 animals of 266 species on display on the small territory. Their reproduction successes resulted even in surplus stock that was sent to parks in other towns, such as Varna, Ruse and Kritchin, forming the start of a zoological collection in these places. In Sofia Zoo, however, progress continued with creating the terrarium holding South European snakes and lizards, as well as a young Mississippi alligator donated by a lady from Sofia who had bought it at the World Exhibition in Chicago. Meanwhile other species were added to the collection, such as a pair of lynx in 1902, two Tibetan yaks in 1905, and the rare Carolina parakeet, indigenous to the United States of America. The latter was introduced by Adolf Schumann who was appointed as general inspector of the Zoo in 1911 and who had gained experience in zoos and private collections in Austria and Germany. His terms ended in 1940, while the Carolina parakeet's terms ended with extinction - although one of the only two stuffed specimens of this parakeet in the world can be seen in the collection of the Museum of Natural Science in Sofia. In 1912 the Zoo received a male and a female Asian elephant from Tierpark Hagenbeck in Hamburg. These two pachyderms were first put in temporary enclosures at the stables of the royal palace in Vrana, where Prince Ferdinand began his animal collection. Zoo management had problems designing and building a proper enclosure for the elephants, which led to a prolonged stay in Vrana until well after the end of WWI. Sofia Zoo survived the war undamaged, but it took another ten years before the elephants could be transferred to the royal zoological gardens, in 1929Elephants enclosure royal zoo Sofia. That was the beginning of the tradition of keeping elephants in Sofia Zoo, which is reflected in the Zoo's logo today, an elephant with a crown on topSofia zoo logo. These first two elephants never procreated while the male passed away of an anthrax infection in 1940, and the female died of an internal parasitic infection in 1953.

In this period a special annual log-book was meticulously kept by the veterinarians, which also proofed all animals were well taken care of. Having a keeper on duty every night was another sign that this was the case.

Then WWII broke out and this war didn't pass unnoticed. As Bulgaria supported Germany - at least politically - and didn't expel German forces from its territory, the Soviet Union declared war on Bulgaria in 1944. This led to heavy allied bombing on Bulgaria's capital. However, while this left Sofia in ruins the Zoo escaped total destruction, as the rest of the country suffered little damage as well. While many terrified Sofia citizens had fled to the countryside, the zookeepers searched the streets and ruins of Sofia for dead horses, oxen and other domestic animals to feed the remaining carnivores. But they also had to make difficult decisions about which ungulate of the remaining collection had to be shot to feed the carnivores, as there was a constant shortage of meat. Thanks to the dedicated efforts of the keepers, the zoological garden continued to exist after the war when, in 1945, Bulgaria became an independent socialist republic. And while Sofia Zoo was completely restored, it became part of the Bulgarian Academy of Science in 1947.

The change of geopolitical influence on Bulgaria after WWII made it easier for the Zoo to acquire its first shipment of new animals from the Soviet Union, East Germany and other socialist countries in the 1950s. Fortunately, animals arrived from other regions as well, with a pair of Asian elephants as the highlight in 1954. They were shipped to Varna harbour and from there travelled by train arriving two days later in Sofia Zoo. The male elephant had only a short life at the Zoo. He died in 1964, but not before he had made the elephant cow pregnant. The happy occasion of the first ever birth of an elephant calf in Sofia Zoo took place on 13 April 1965. Although lively and playful, the female calf had to be bottle-fed, because she wouldn't drink from her mother. Despite this, she grew up healthy and strong until at the age of three a sadistic visitor gave her a loaf of bread with needles inside which led to her painful death. The second elephant calf born at the Zoo in 1973 awaited a similar fate. The bull calf was poisoned by another deranged visitor using strychnine.

As of 1960 Sofia Zoo was under the management and administration of the municipal government. Meanwhile the animal collection grew steadily and new species such as penguins, antelopes and zebras were added regularly. It became obvious that the size of the available grounds was too small, both for the number of animals and the increasing number of visitors. Due to the enormous interest of the public it was decided to have the Zoo remain open during the winter season of 1965-1966, for the first time ever. Altogether it was clear that the Zoo had to expand. A plan was conceived for building a brand new zoo in 1966 by architects Radoslavov and Iliev in the foothills of the Vitosha Mountain. The construction was an enormous task for the municipal authorities, but work commenced and with the significant help of Sofia citizen volunteers the three stages of construction were as good as completed in 1983. So, after 15 years of building a new site of 24 hectares (and another 12 hectares for future development) was ready to receive the animals. The transport of the animals to the new site was an enormous operation which required lots of preparatory work. A large number of special wooden crates were made to facilitate the transfer of the different animals, while a special big metal cage was created for the Zoo's single elephant cow, the one who lost both her newborn calves due to insane actions of two visitors. The mass animal transfer was carried out in 1984 with the last animal arriving from the old site in August. On 10 September 1984 the brand new Sofia Zoo was officially opened.

Having spent nearly all their money on this huge project a financial predicament awaited. Especially, because they couldn't let Sofia Zoo's 100th anniversary in 1988 pass unnoticed. But thanks to many grants, gifts, presents, legacies, and donations from Bulgarian citizens and many wealthy Bulgarians living abroad these 100th anniversary celebrations were made possible after all. On the day of its 100th anniversary, the Zoo had nearly 2,500 animals on display of about 250 different species.

In 1968 the Zoo already had started its education programme for children in a so-called zoo school, but following the modern trend in zoos more emphasis was placed on this function in the 1990s. In 1998 the Zoo founded the Environmental Education and Research Centre (EERC), located in a separate building in the 'heart' of the Zoo grounds. Apart from engaging the public in the objectives a modern zoo stands for, such as zoo animal welfare, nature conservation and research, the people working at the EERC collaborate with many relevant institutions in the field of education, conservation and research work.

Similar to what many other zoos in the world did, raising additional funds for the Zoo to address the broad scope of its mission was paramount. For this purpose an animal adoption programme has been set up and in operation since 1995. This implicitly created a valuable group of people that can be called 'friends of the zoo.'

In 2009 a remarkable incident showed how vulnerable an institute such as Sofia Zoo can be. Due to a pricing dispute between Bulgaria and Russia the Russian gas supply was stopped, and as a consequence the central heating at the zoo was shut down. About a third of the 1,300 animals at the zoo were vulnerable to the resulting cold and employees had to find portable electric and oil heaters to heat their enclosures.

As of 2013 the Zoo focusses also more on its botanical function with a dendrology route that has been developed, along which visitors can see 40 interesting species of trees and shrubs from around the world.

Nowadays, Sofia Zoo covers an area of 36 hectares, which makes it, besides being the oldest, also the largest zoo in the Balkans. The Zoo is engaged in nature conservation activities by participating actively in national and international breeding programmes for rare and endangered species such as birds of prey, big cats (Persian leopard, Amur Tiger, Eurasian lynx) and antelopes.

The future
Sofia Zoo is currently (2018) a candidate member of the European Association of Zoos and Aquaria (EAZA), and it is in the process of upgrading its facilities to meet current European standards in preparation for becoming a full member of EAZA.

3500 BCE

Nekhen, Egypt

The oldest known zoological collection was revealed during excavations at Nekhen in 2009 of a menagerie that dates to about 3500 BCE. Nekhen was the religious and political capital of Upper Egypt at the end of prehistoric Egypt (3200–3100 BCE). The graves revealed remnants of 14 animals in total, including a leopard, two crocodiles, hippopotami, hartebeest, two elephants, baboons, and African wildcats. Read more

2100 BCE

Mesopotamia

In the Mesopotamian region flourishing city-states developed along the Tigris and Euphrate rivers. This area was suitable for agriculture but lacked resources to sustain other technologies. Thus, trade developed over time, and with increasing prosperity the Mesopotamian merchants started trading wild exotic animals as well. These animals became part of animal collections of royalty and wealthy individuals, the one even more impressive than the other. Royalty kept lions and other animals, such as ibis, cranes, herons, pelicans, elephants, ostriches, gazelle and ibex, for exhibition purposes. Royal lions were kept in cages and pits during the Third Dynasty of Ur around 2100 BCE.

The Indus civilization

The Indus civilization along the Indus river in a region what is now Pakistan domesticated animals, in particular elephants. Also they traded wild animals with Mesopotamian merchants, such as elephants, tigers, rhinoceroses and antelope. Authenticating seals used on traded cargo depicting these wild animals give evidence of this. Although no direct evidence exists, it is thought that animal collections have been part of the Indus society due to the above and the fact that wealthy people had access to other ancient societies that held animal collections.

1500 BCE

Expeditions to the Land of Punt

Under the rule of Hatshepsut, the only Egyptian female pharaoh, ambitious and famous expeditions took place to the Land of Punt, in present-day Somalia, between 1510 and 1490 BCE. Many trade goods were bought in Punt, and Egypt had a new supply of myrrh, trees, ebony, ivory, gold, cinnamon, incense, eye paint, skins of southern panthers, and live animals. Like many civilizations that accumulate wealth, Hatshepsut took an interest in exotic animals and ordered to collect live animals, too. The animals brought to Egypt from Punt included apes, monkeys, birds, greyhounds, cattle, leopards, cheetahs, rhinoceroses, and giraffes. They formed the largest known animal collection in Egypt to that time. It is unknown how the animals were housed or maintained, despite the fact that the greatness of the acquisitions was depicted in murals.

1300 BCE

Pharaoh Ramesses II

Egyptian domestications attempts included many different kinds of native wild ruminants and carnivores. These animals were fattened on bread dough, as were many kinds of birds. A variety of birds were kept in domestic flocks, particularly geese and ducks, but also swans, doves and cranes. Wealthy Egyptians at all times kept menageries, in which they brought up the animals taken by the lasso or by the dogs in the desert, as well as those brought into Egypt by way of commerce or as tribute. Egyptians particularly liked to tame as many of these species as possible. Pharaoh Ramesses II for instance had, besides an extensive animal collection of African species originating from the Punt expeditions, a tame lion that not only accompanied him into battle, but also guarded the royal tent at night.

1050 BCE

China , Zhou dynasty

In China it was during periods of unification (the dynasties) that significant animal collections, including exotic species, were developed. These collections served the practical purpose of ritiual sacrifice as well as aesthetical purposes for the wealthy class. These animals were kept in parks or breeding grounds. It started with the Shang dynasty (1600-1050 BCE), but the first well-known animal reserve was created by the founder of the Zhou dynasty (1550-221 BCE), Wen Wang. These animal reserves or parks were large, walled-in natural areas that required their own staffs of administrators, keepers and veterinarians.

700 BCE

First ‘suitable’ animal enclosures

In Mesopotamia Sennacherib's predecessors kept a variety of animals in parks. Herds of deer, gazelle and ibex for instance were transported from conquered territories to Assyria, and species like lions, apes, ostriches and falcons of which some species were never before seen in Assyria. Not only animals were imported, also foreign trees and fruiting plants. But, Sennacherib was the first to create dedicated areas for these exotic animals and plants as an ecosystem exhibit. He is also believed to be the creator of the famous hanging gardens of Babylon, which were actually at the palace garden of Sennacherib located at Nineveh.

330 BCE

Greek animal collections

The Greek interest in science reflected their attitude towards animals which went beyond observational knowledge. Animals played a central role in their culture and mythology, and their animal collections during this period were not just about displaying power, but also about understanding the animal kingdom. Due to the military campaigns into Asia by Alexander the Great, the Greek not only expanded their territory significantly but their curiosity horizon as well. Alexander sent many exotic animals back to Aristotle. Philosophers like Aristotle studied animals for scientific purposes, and his writings indicate a rudimentary approach to zoology. Whether the animals remained alive and maintained in collections is still unknown.

27 BCE - 476 CE

Roman Empire

The Roman view on nature was similar to the Greek attitude, practical and utilitarian. In other words use natural resources productively. Meaning that extensive agriculture, deforestation, mining and hunting had significant environmental consequences. So at the end of the reigning period of the Roman Empire (around 500 CE) they had depleted many of their natural resources, including wild animals in conquered territories in Europe, Africa and Asia. These exotic species, such as lions, leopards, ostriches, hippopotamuses, crocodiles, monkeys, rhinoceroses and elephants were captured or diplomatic gifts and sent back to Rome.

Animal entertainment in the Roman Empire

Early Roman Republic baiting (around 500 BCE), where animals were used to attack another animal, evolved into increasingly elaborate spectacles called venationes. These type of public spectacles featured contests between beasts or between men (prisoners) and beasts staged in an amphitheatre, usually in connection with gladiator shows. Lions, hyenas, leopards, giraffes, and rhinos entered the arena and were, in most cases, killed. The scale of this slaughter was enormous, with over 9,000 animals being ordered, transported and killed for a single event: the inauguration of the Colosseum in Rome in 80 CE. The animals must have been sourced from animal collections, but not much has been written about how and where the animals were kept. When the animals were not scheduled for fighting, they were used in yearly parades honouring those who passed away.

500 CE

The end of terrible animal abuse

The disintegration of the Roman infrastructure led to the loss of the Roman animal collections, and fortunately the abuse during the venationes. Monarchs, monasteries and municipalities, however, continued to keep their wild animal collections in villa gardens, large parks and hunting reserves. It were these collections, that continued to the Medieval period, and emerged as the menageries of the aristocracy during the Renaissance period. Again, or perhaps still, the animals were considered symbols of power and wealth.

500 - 1500 CE

Persian and Arab animal collections

When the Islamic caliphate expanded (ca. 622-1492 CE), gardens and parks that were influenced by the Persian re-creations of the Garden of Eden were introduced in conquered territories. Although natural sciences, unlike other sciences, were not considered important by the Arabs, animal collections were kept in those parks. For instance Abderrahman III (912-961 CE) established an animal park in the city of Zahra north of Cordoba, Spain. Here, animals were kept in cages and fenced enclosures. These Arab collections continued through the Medieval and into the Renaissance period. During both periods, animals were exchanged between European and Muslim rulers.

Medieval animal collections

During the Middle Ages in Europe, the keeping of exotic animals became a symbol of royal privilege. The first zoos emerged as private menageries, being spectacles of power and wealth enjoyed exclusively by royalty, the Church and the aristocracy. The animals were seen as exotic collections to be displayed, rather than living creatures deserving of compassion. Tigers, lions, bears, and elephants were kept in cramped cages or chained up, with bare stone floors and minimal shelter from the elements. But this was of little concern to the menagerie owners. The animals existed solely for the amusement of their high-status visitors. The menageries existed in many countries, such as England, Switzerland, Holland, Denmark, France, Italy and the Vatican. Pope Leo X kept tropical birds, lions, leopards, other cats and mammals.

Aztec and Inca animal collections

Aztec and Inca civilizations were continuations of Americas’ earlier civilizations that may be as old as those of the Old World. They reached their heights and flourished between 1400 and 1500 CE. The Aztecs were well-structured and traded throughout the Americas. Extensive gardens and royal forests contained impressive animal collections. The Aztec emperor Montezuma II, in what is today Mexico, maintained one of the earliest animal collections in the Western Hemisphere. It was destroyed by Hernan Cortes during the Spanish conquest in 1520, who left in writing detailed descriptions of the beauty and value of what he destroyed. The Incas, like the Aztecs, had animal collections and gardens, both real and artificial. No detailed information on these collections was left by Pizarro, who conquered the Inca civilization.

1500 - 1600 CE

Public access to private collections

During the Renaissance period the rich elite occasionally allowed naive citizens to view their collections. The Medici family in Florence was one of the first to allow public viewing of their menagerie, after relocation of their collection to San Marco in 1550, via a viewing area in the adjacent amphitheatre*. Thus, setting the stage for the zoos that would follow. This introduction to exotic wildlife to the public accelerated when travelling menageries came into existence and zoos were founded which allowed the common people to visit their grounds.

1600 - 1800 CE

The Age of Enlightenment

The Age of Enlightenment in Europe was an intellectual and philosophical movement in the 17th and 18th century during which new ideas and world views were developed. There was a surge for intellectual and scientific progress, which fundamentally changed the interaction of mankind with the natural world. It was during this era that the concept of the zoo became more than merely a public spectacle. There was more attention for the study and conservation of animals and nature in general.

1752

Tierpark Schönbrunn in Vienna

Tierpark Schönbrunn in Vienna, the oldest existing zoo in the world, founded.

1826

London Zoo

London Zoo founded with a clear scientific mandate, which marked a significant evolution in the concept of zoos.

Many more cities established zoos

Many cities in Europe and North America followed by establishing their own zoo, responding to people’s growing fascination with exotic places and animal, and often inspired by the model of London Zoo. Hence, the role of the zoo altered, and the zoo became a place where education, research, and leisure converged, allowing people from all backgrounds to engage with and learn about nature, specifically the animal world.

1870 - 1958

Indigenous tribes on display

In the 1870s and 1880s it became common to display groups of indigenous peoples from Africa, Asia, South America and the Pacific Islands. These peoples were seen as scientifically "primitive" or "exotic". The so-called "ethnographical displays" were travelling exhibitions, but were also part of entertainment in zoos. It died out after World War II. Oddly it was Hitler who first banned them. The last was in Belgium in 1958.

1874

Philadelphia Zoo

America’s first zoo, Philadelphia Zooopened its gates to the public on 1 July 1874.

1900 -

The Hagenbeck revolution

In the early 1900s the way animals were exhibited in zoos changed. Carl Hagenbeck, a German animal entrepreneur from Hamburg, decided that his travelling exhibition of animals and indigenous people should be on display at a permanent home, the Hagenbeck Tierpark (Hamburg Zoo). More importantly, the animals had to be displayed with an unobstructed view in a natural setting. So, the bar-less, moated open-air enclosures with panoramic views were introduced. As practically every major zoo, circus or private collector in the world bought animals from Hagenbeck the animal handler, his ideas on zoo design spread fast.

1907

Hagenbeck Tierpark

Hagenbeck Tierpark in Hamburg was founded by Carl Hagenbeck and opened its gates to the public on 7 May.

Nature depleted of its wildlife

The ever increasing number of zoos needed exotic animals urgently, while these exotic species often died in captivity without producing offspring. Therefore, wild animal traders like Carl Hagenbeck sourced their animals in the wild. This raised concern, because it became clear that a dramatic number of species was decreasing in the wild at the beginning of the 20th century. The planet’s biodiversity needed protection and conservation.

1914-1945

The World Wars

Both World Wars had a rather devastating effect on zoos, especially in Western Europe. Lack of staff, food, feed and fuel, and destruction by bombs led to a decreased number of species and specimens, let alone that hungry citizens went after the zoo animals.

1929 -

European bison

European bison, or wisent, once roamed wild throughout large parts of Europe. However, European bison went nearly extinct in the wild, except for 54 animals remaining in European zoos. Fortunately, a breeding programme initiated in Poland in 1929 managed to save Europe’s largest land mammal. The European bison now has its own EAZA Ex-situ Programme (EEP). Thanks to the conservation efforts, reintroduction projects and breeding centres, bison population is now growing and spreading. In December 2015 there were 6,000 bison in Europe: 4,400 in the wild or living in semi-wild conditions and 1,600 in captivity. Saving the European bison from extinction is considered one of the biggest successes in European conservation for which zoo populations were essential. Nevertheless, European bison is still a vulnerable species and zoo populations are still essential, and more work needs to be done in the continued conservation efforts of this impressive species within Europe.

1935

World Association of Zoos and Aquariums

WAZA, founded in 1935 during the interbellum, is the "umbrella" organization for the world zoo and aquarium community.

1960 -

Focus shift towards conservation, animal welfare and education

Nature’s state of affairs at the beginning of the 20th century was not forgotten after the wars. So, after rebuilding and repopulating their own zoo, the zoos began to shift their focus from mere exhibition to conservation and education. This marked the beginning of ethical considerations, for the first time in the history of zoos. Growing public interest in animal rights and criticism of welfare standards in zoos led to questioning the concept of zoos as such - causing the many zoos and zoo organisations to re-evaluate their role.

Zoo conservation efforts

During the 1980s and 1990s many individual zoos started to put more emphasis on the role of conservation in their activities. Jersey Wildlife Park (now Durrell Zoo) was one of the pioneers of this new kind of zoo which kept wild animals primarily for conservation purposes, identifying a threefold purpose of biological study, captive breeding for reintroduction, and education and training, all focussed on actively supporting the survival of threatened species.

Animal welfare improvements

To improve animal welfare zoo management slowly accepted that enclosure design should be made fit for purpose. The purpose being to facilitate the animal to express natural behaviour, including climbing, seek shelter and social interaction. And easy to clean barren cages of concrete did not fulfil the requirements. So, building on the concept of Hagenbeck, enclosure design embraced natural settings with trees, shrubs and boulders.

Endangered species breeding programmes

The zoo world acknowledged that continuation of sourcing endangered species from the wild would be counterproductive in the end. This caused a shift in zoo policy worldwide, knowing that diversity of animals in the wild was at stake made breeding of endangered species in zoos necessary. Maintaining the diversity of the animal kingdom became the main driver for many zoos. In addition, they understood they had to work together to make breeding endangered species in zoos a success. Taking part in breeding programmes is a requirement to be member of a continental zoo organisation and/or the global zoo organisation WAZA.

1972 -

Arabian oryx

In 1972 the Arabian oryx was officially declared extinct in the wild. An ambitious rescue plan led by the Fauna Preservation Society (now known as Fauna & Flora) had been developed in the 1960s, Operation Oryx. A few specimens of the last surviving individuals in what is now South Yemen, were captured. Captive breeding was set up with the zoo community, with contributions of Phoenix Zoo, London Zoo, San Diego Zoo and more. The ex situ breeding proved to be very successful, with 1,600 Arabian oryx distributed over the world zoo community by 1992. Returning them to the wild was a bigger problem, because hunting by poachers still was the main threat. Nonetheless, the IUCN was able to reclassify the Arabian oryx as Vulnerable in 2011, but hunting remain a serieus threat to this day.

1982 -

California condor

In the 1960s the California condor was facing extinction due to the destruction of habitat, poaching, and lead poisoning. In 1982 it was decided - when only 22 birds remained in the wild - that all the remaining condors would be brought in for protection and captive breeding. San Diego Zoo Global was given permission to begin the California Condor Recovery Project. The programme involved the U.S. Fish and Wildlife Service, California Department of Fish and Game, the National Audubon Society, and the Los Angeles Zoo. The project became one of the best examples of recovery programmes of endangered species. Already in 1991 they started to release captive-bred condors into their native habitat, and within 20 years the population of California condors grew to almost 200 birds. It required development of techniques to avoid the condor chicks to know they were actually hand-raised by humans. In October 2014, the total population of California condors was 425, of which 219 living in the wild. Today, captive-bred condors have been successfully released into the wild in Arizona, and Baja California, Mexico. More than 50 California condors now join the population every year, and more importantly 12 to 15 chicks now hatch in the wild annually.

1992

European Association of Zoos and Aquaria

EAZA is founded in 1992 and works to facilitate cooperation within the Europe and Western Asia zoo and aquarium community towards the goals of education, research and conservation. Its parent organisation is WAZA.

1994 -

Socorro dove

The last record of an individual of the Socorro dove in its natural habitat, Socorro Island on the Revillagigedo Archipelago (Mexico), was in 1972. Nonetheless, it took the IUCN 12 years to officially declare the Socorro dove extinct in the wild. The decline and extinction in the wild of this species is caused by human predation, high levels of understorey grazing by sheep, and predation by feral cats. However, doves that were brought to California in 1925 allowed for captive breeding in the USA and later in Europe. Today, facilities in Europe, the United States, and now Mexico breed Socorro Doves in their aviaries as part of the globally managed breeding programme. Currently there are circa 150 birds in captivity. Reintroduction of the species in the wild on Socorro Island requires careful planning, because habitat destruction and predation must be avoided at all times.

1996 -

Przewalski horse

Przewalski's horses once ranged throughout Europe and Asia. Competition with man and livestock, as well as changes in the environment, led to the horse moving east to Asia, and eventually becoming extinct in the wild. Today they can only be found in reintroduction sites in Mongolia, China, and Kazakhstan. The Przewalski horse was declared extinct in the wild from the 1960s up to the official assessment in 1996. The IUCN reassessed the species in 2008 due to at least one surviving mature individual in the wild, so this led to the classification of critically endangered. Due to successful reintroductions of captive-bred horses at zoos, the population in the wild is currently estimated to consist of more than 50 mature individuals free-living in the wild for the past seven years. This apparently allows for another upgrade on IUCN’s scale in 2011, and make it just endangered. The small population size and restricted range, make the wild Przewalski horse vulnerable for potential hybridization with domestic horses, loss of genetic diversity, and disease.

2000 -

Enhanced animal care and conservation efforts

In zoos and umbrella organisations on regional and global level, advancing technology and knowledge are taken into account in policies and budgeting. Money is used for hands-on research for developing better husbandry and care systems next to conservation projects on location for better understanding of the causes and consequences of the degradation of natural habitats on wildlife populations. The ultimate goal of research collaboration between zoos, research institutions and universities is to preserve the species at stake.

Enhanced visitor engagement

To get across the message of the current state of global and local nature, its biodiversity and measures needed to preserve or improve this, it is important that zoo visitors get the information in such a way that the message will stick. To enhance the educational outreach many zoos use mobile apps to inform the visitors and help them tour the zoo grounds. Zoos offer close encounters with the animals - via feeding sessions or via walk-through exhibits or other kind of immersive enclosure design - to make the experience of the zoo visit more impressive. However, current technology can enhance these experiences to another level. Zoos are experimenting with augmented reality and virtual reality to assist their educational efforts. Especially virtual reality, where people immerse in a fully digital world can create experiences beyond people’s imagination. It will trump the static signs at the enclosures with lots of text to read when it comes to the take-home message.

Zoos become important for global biodiversity strategies

By addressing biodiversity conservation via research and educational efforts, zoos become important players in the implementation of global biodiversity strategies. They contribute to the achievement of targets set by international agreements like the Convention on Biological Diversity (CBD) and the United Nations’ Sustainable Development Goals (SDGs). By participating in these global efforts, zoos help to address critical issues such as habitat loss, climate change, and species extinction.
