When the Conservation Claim Outruns the Evidence
Ambassador animals, captive breeding and the gap between a memorable encounter and demonstrated conservation
A keeper walks a cheetah on a leash. A family reaches into a stingray touch pool. A bird flies toward a presenter during a zoo show. When experiences like these are justified as conservation education, an important question follows: what evidence supports that justification?
ㅤ
An encounter may entertain, attract attention or leave a lasting memory. Demonstrating conservation benefit requires a further connection: what did visitors learn, what did they subsequently do, and how did those actions help wildlife? The appeal of an experience cannot answer those questions on its own.
ㅤ
What did closer contact actually add?
ㅤ
At Cheetah Outreach in South Africa, Whitehouse-Tedd and colleagues studied 182 visitors. Guided tours and combined tour-and-encounter experiences produced greater knowledge gains than encounters alone. Adding an encounter to a tour provided no statistically detectable additional learning advantage.
ㅤ
Visitors selected their experiences, and tours lasted about 30 minutes compared with roughly five minutes for encounters. Those differences limit conclusions about touching itself. Nevertheless, the study gives institutions reason to examine whether the encounter adds educational value beyond what a tour already delivers.
ㅤ
A more direct test of touching
ㅤ
In a 2025 Oklahoma City Zoo study, Barrett and Snyder randomly assigned 300 adult zoo members to elephant or stingray experiences delivered by video, in person without touch, or in person with a touch opportunity. Information and demonstrations were comparable.
ㅤ
Touch offered no significant advantage over in-person viewing in knowledge, emotional responses, empathic concern or conservation intentions. In-person experiences generally outperformed video for emotion, concern and intentions, but the extra step of offering touch did not produce an additional measurable benefit. The sample was restricted to zoo members, and some stingray participants did not actually make contact.
ㅤ
The pattern extends beyond cheetahs
ㅤ
Clifford-Clarke and colleagues examined Humboldt penguin experiences at Twycross Zoo, analyzing 134 visitors who completed both questionnaires. Visit types included an encounter with hand-feeding, a penguin parade with an educational talk, ordinary exhibit viewing and a control visit without viewing the penguins.
ㅤ
Although the researchers reported some improvements in conservation knowledge and stated intentions following the zoo visit, they found no evidence that encounters improved conservation-education outcomes. Visitors chose their activities, and later conservation behavior was not verified.
ㅤ
At Oakland Zoo, Kirsch and colleagues analyzed 299 complete surveys at an illegal-wildlife-trade exhibit. Visitors demonstrated more knowledge of conservation behavior after seeing the exhibit whether or not a trainer presented an ambassador ball python or yellow-naped Amazon parrot. Adding the ambassador did not measurably improve the learning outcome. This tested animal presence, rather than touching, but it challenges another assumption: that a live ambassador necessarily strengthens the educational message.
ㅤ
Feeling connected is not the same as following through
ㅤ
Research by Rank and colleagues reported feelings of connection during ambassador programs and found that facilitators’ questions could stimulate curiosity. Those are legitimate educational outcomes. They do not establish that physical contact was necessary or that visitors subsequently took action to protect wildlife.
ㅤ
The distinction matters when describing a program to the public. Attention, enjoyment, empathy, knowledge, intentions and verified action are different outcomes. Evidence for one should not be presented as though it establishes the entire chain from encounter to conservation.
ㅤ
Breeding for zoo programs: how does that protect animals in the wild?
ㅤ
Samantha L. Smyser’s 2024 West Liberty University thesis, “Ambassador Animals and the Population Sustainability Initiative Within the Association of Zoos and Aquariums,” brings another part of the justification into focus. Its abstract emphasizes maintaining captive populations through genetic diversity, demographic stability, successful breeding, husbandry expertise and available space.
ㅤ
The stated aim includes keeping commonly used ambassador species available for future programs. The abstract links that availability to anticipated educational and conservation benefits, but does not demonstrate protection of wild populations.
ㅤ
Breeding animals to keep zoo programs going does not, by itself, establish that those programs save animals in the wild. The educational and conservation benefits invoked to support continued breeding require evidence of their own.
ㅤ
A brief welfare assessment cannot answer a lifetime question
ㅤ
The cheetah study also assessed five animals, with encounter and heart-rate measurements involving four. Its findings were reassuring under the conditions studied, including lower heart rates during stroking. Those findings cannot establish lifetime welfare or justify every aspect of an animal’s captive life.
ㅤ
A 2026 scoping review by Cooper-Rogers and colleagues examined 49 articles representing 50 studies of animal interaction programs, covering research through the end of 2024. Positive, neutral and negative welfare outcomes were reported, alongside substantial gaps in the species and programs studied.
ㅤ
An animal appearing to tolerate an encounter does not establish that its overall needs are met. Likewise, a visitor enjoying the encounter does not establish that the animal benefits. Welfare requires its own assessment, independent of the experience’s popularity or educational label.
ㅤ
The burden belongs to the institution making the claim
ㅤ
A 2021 systematic review by Spooner and colleagues found that only two of its 19 peer-reviewed articles assessed both education and welfare. The authors called for stronger assessments of both. Several papers discussed here also share researchers or draw on overlapping literature; they should not be counted as wholly independent confirmations.
ㅤ
These findings do not establish that every ambassador program is ineffective or harmful. They do identify a gap between outcomes that have been measured and the broader conservation case sometimes built around them. A finding of no statistically detectable difference also leaves uncertainty; it is not proof that all experiences are equivalent.
ㅤ
Institutions invoking conservation to justify encounters and breeding should be able to explain what the encounter adds, whether comparable learning is possible without contact, what visitors actually do afterward, and how the animals’ welfare is evaluated. Where protection of wildlife in nature is claimed, the connection should be demonstrated rather than assumed.
ㅤ
Conservation claims require conservation evidence. The burden is on the institution making the claim.
