IntroductionIn today's overpopulated world, the concept of wilderness is naive for most part. Wild animals gradually adapt to men-made environments - more or less successfully. In many parts of the world, migration of terrestrial wild animals is limited by fences along highways and properties as well as train tracks and urban developments. Their populations range freely in fragmented habitats with hardly any migration. As a consequence, many species are no longer self-sustaining and need to be managed. They become semi-wild.

Spreading human settlements will speed up the development of semi-wild animal populations. The existence of purely wild populations is questionable in 50 to 100 years.

Wild animal populations can be of four kinds:

• indigenous, born in the wildExample: native animals, including regular migrants and those that immigrated on their own.Note: Indigenous is not absolute. In Europe, the word "indigenous" is used to differentiate native species from those that were introduced after 1500, when long distance travel became common.

• bred (not indigenous), raised in the wildExample: European deer released in New Zealand for hunting.

• indigenous, born and raised in captivity and releasedExample: conservation project species such as the Californian condor and others.

• bred as pets or farm animals, released or escapedExamples: minks, dogs, pythons, parrots and others.

Sometimes, we can find all these forms in one place, for example in European rivers. Trout and salmon cannot travel in many rivers due to various man-made barriers. Wild fish populations therefore have been augmented with captive bred fish. Even specialists now cannot always differentiate between wild and bred species in the waters. The fish population is monitored and fishing permits are adapted to the status of the population. The commercially useful fish populations therefore are semi-wild.

The transformation of wild populations into semi-wildWild animal populations are being influenced by human presence, and - the more successful ones - adapt to human lifestyles and landscapes. An increasing number of animals will lose their wild habitats and find new ones in human settlements. This makes them dependent on human activities and management.

In the case of human-animal conflicts, animals are killed, or captured and relocated. Relocations to zoos are common today. However, when numbers increase, not all of them can be kept in zoos. They will be managed in more extensive environments and become semi-wild.

Unintended domesticationSemi-wild is on the way to domestication. While domestication is normally genetic selection for a certain purpose, such as more meat or milk, it is also the unintended result of managed breeding of small populations - not just in captivity. The following are indications of domestication¹ that can be found in some populations of semi-wild animals.

• smaller brain, shorter intestines, smaller or less horns and teeth, less fur, reduced sexual dimorphism

• variations in colour

• less aggression, less defensive behaviours, shorter flight distance

• less seasonal behaviours, difficulties in maintaining a stable body temperature

• slower development, neoteny

• more young, less parential care

Domestication is favoured by tight holding systems, the provision of high quality resources, and by reducing competition for those resources.

Several species are currently becoming domesticated as a side effect of commercial breeding: deer, edible fish like trout and salmon, pet parrots, chimpanzees and tigers, hunting and show raptors like falcon, buzzard and eagle.

Zoos' favouring of less aggressive and less defensive individuals and those that are less sensitive to disturbance, unintentionally leads to domestication.

Translocation of animalsAdaptations to captivity can impede animals from surviving in the wild upon release. Managing the exchange between animal populations therefore requires reduction of stressors by using various methods such as.

• anaesthesia, captivity in-situ, acclimatisation, medication for the translocation of wild animals into captivity;

• pre-release training and acclimatisation, conditioning for transport, post-release provisioning for the release of captive animals into the wild;

• conditioning for transport for the exchange between semi-wild populations.

Experiences with technical procedures for the translocation of wild animals into captivity are well known. Legal hurdles however can be massive, particularly when export is required. Taking wild native Australian species out of Australia is almost impossible. Unfortunately, zoos are involved in wild animal "laundering" by taking in wild-caught animals, breeding them and exporting the captive bred young.¹

The translocation of captive animals into the wild is far more difficult than the translocation of wild animals into captivity. IUCN guidelines exist, but are often ignored by release project managers. Experiences and success rates are low, costs are high.¹

Managing meta-populationsReintroductions are usually done by public agencies. Only a small number of re-introduced animals come from zoos, most come from special facilities. A good share of re-introduced animals, however, are captive-bred descendants of zoo animals. Zoo expertise is often used in re-introduction projects by involving zoo veterinaries, curators and keepers. Methods for catching, marking, feeding and treating animals are developed in zoos.¹

The current strength of zoos is not the breeding and reintroducing of animals, but serving as back-up for meta-populations and providing expertise for translocations.¹

Animals bred in semi-wild conditions are better suited for translocation to semi-wild or wild conditions than zoo animals. Such transfers are easier, cheaper and more successful.¹ Several zoos therefore establish and support special facilities for breeding animals in semi-wild conditions. This is more cost effective and produces more genetically sound animals than fragmented minimalistic breeding populations with two to five animals per species that most zoos keep.

Goldau animal park in Switzerland contributes to the management of the bearded vulture meta-population. The zoo displays bearded vultures, runs a breeding facility without visitor access and re-introduces off-spring to the wild.

Opportunities for visitor attractionsSemi-wild animal populations may generate additional opportunities for visitor attractions. The observation of red deer at scheduled times by paying visitors is a typical wildlife experience in Austria. In this case, the differences between wild and domesticated blur, as well as the differences between captive and wild.

Zoos work on developing holding systems that visitors do not perceive as captivity, such as landscape immersion exhibits. In German zoos, the keeping of wallabies, maras and muntjac free-range in zoos is common.

Visitor encounters with animals are organized in various forms:

• captive = animals confined and intensively managed

• free range = animals mixed with people and intensively managed

• semi-wild = animals partly self-sustaining, managed, not tamed or domesticated

• wild = animals self-sustaining and not managed

Zoo Salzburg feeds a population of griffin vultures that is partly zoo-born. Some stay in winter instead of migrating to the South. These birds are untamed, but conditioned, tagged and managed semi-wild.

Viewing semi-wild animals will become more common in the future, if only for economic reasons. Managing animals is more sustainable when it pays off by earning money from visitors. The organizational framework for these animal attractions will have all kinds of names and legal backgrounds, including protected areas in agricultural and forestry land.

Future zoo collection considerationsHow will meta-population management influence global zoo collection plans?

Many collection plans list only generic species without specifying the subspecies because the future animal owners don't know and/or don't care about the difference. In fact, not many people know and care about inbreeding of animals. Some of them run zoos and do not consider hybrids as being a problem. From a global perspective, the criteria for selecting species will probably stay simple in the future, being driven by

• perceived public preferences

• personal preferences

• budget and availability

• education by representing of most taxons

• recommendations from breeding programmes and IUCN

• CITES and national legislation

The species of a common animal collection are not hard to obtain in most places because there are enough dealers - including zoos and other operations - that sell captive-bred animals.

Zoos with more ambitious collection plans, however, have difficulties obtaining the animals they wish, even when they are well-established institutions. Import and transfer legislation are real restrictions for such collections. These difficulties will increase in the future.

A recent discussion in the EAZA journal Zooquaria² revealed the problem of breeding genetically sound tigers in zoos. The demand for tigers is just too great to be answered with genetically pure tigers. However, instead of changing the collection plan, some zoos would rather take inbred tigers and continue breeding them.

Chances are that the typical charismatic zoo species will become even more inbred and domesticated within the next 100 years, while their wild counterparts will go extinct. The common zoo in 50 to 100 years may be a cocktail zoo, keeping

• hybrid orangutans, giraffes, tigers, lions

• inbred white rhinos, elephants, parrots

• groups of male-only elephant, gorilla, and antelope groups

Monika Fiby 3

• laboratory retired chimpanzees, baboons, macaques

• rescued problematic bears, raccoons, monkeys

• rehabilitated native raptors, storks

Suggestions for counteracting the trendsIn order to counteract these undesirable trends we will need to promote concepts that differ from the cocktail zoo. We need to:

• develop collection plans and designs for meta-population management

• promote exhibitions of animals from the zoo's own bio-region

• develop semi-wild animal management and display

First, the management of meta-populations needs to become more common.

One obstacle in meta-population management is that zoos may risk empty exhibits when they hold only a few animals of the managed populations. Obviously, the keeping of more specimens per species, - on or off-exhibit, - as back-up would help. From the visitor attraction point of view there is no evidence that people would not happily spend their time with less species in higher numbers. In contrast, visitors spend one to two hours around six brown bears which is the total animal collection at the bear sanctuary in Arbesbach. Emmen Zoo is an example of a successful zoo with large groups of not very many species. Fifteen macaws in a large aviary are definitely more attractive than two.

In special cases, the rotation exhibit concept may help. The mink exhibit at Wiesbaden Animal Park may serve as an example. The European mink is bred for release by the EuroNerz organization. In order to promote their work and to reduce their space needs, they encourage zoos to take pregnant females in the beginning of summer and return the female with the young in winter. The Wiesbaden Animal Park wished to participate in the breeding program for European mink, but did not want to build an exhibit that will be empty for part of the year.

The solution is to alternate the mink with the park's ferrets in three rotation exhibits. While the minks are away, the ferrets are on display. The story about the mink's domesticated relatives is as interesting as showing pets in the habitat their wild ancestors are adapted for.

Second, the display of native animals needs to become more popular. There are great examples of native animal parks, however they are not the big well-known ones. As long as "cocktail zoos" are promoted, people will expect cocktails at the zoo and zoos will feel forced to serve cocktails. This becomes a self-fulfilling prophecy, reinforced by visitor surveys along the lines "we have great lions - what would you like to see?"

Third, the display of semi-wild animals needs to be developed. There are good examples and ideas³, but they are still rare in zoos. At Paignton Zoo visitors can observe semi-wild badgers at night from a hide. The bald ibis in the wild animal park in Grünau - the place that Konrad Lorenz made famous - are kept in an aviary in winter and fly free in summer. Ravens and geese fly free, but are conditioned to come for feeding times.

Delivering good memorable experiences of wild and semi-wild animals is not common today. Because it is not very reliable it needs back-up from other experiences, but it can be developed easily and at very low cost.
