New UK Zoo Standards Boost Animal Welfare
If you visit a zoo, you might be captivated by the animals you see – majestic lions, curious meerkats, soaring birds of prey. But this is not always the case. Some zoos don’t always give us that impression of “happy animals” where they can behave naturally and be left alone by visitors if they wish.
The UK, Scottish and Welsh governments recently released new zoo standards for Great Britain. So what does this mean for the future of zoos?
I have been working in and with zoos for over 20 years. I am a bit of a zoo-nerd but that doesn’t mean that I like them all. I am an advocate for good animal welfare in zoos and so I can recognise the ones that are good and not so good.
Britain is one of a few countries such as Belgium, South Korea and New Zealand that have specific zoo legislation. The new British standards will be enforced in 2027, giving below-par zoos two years to up their game.

I speak here in my role as associate professor of zoo animal welfare at Nottingham Trent University, but I also sit on the UK Zoos Expert Committee and helped to write the new standards. One of the biggest changes is the replacement of the word “should” with “must”. The standards now say: “Zoos must provide appropriate accomodation”. This makes all elements of the guidance much more enforceable.
One of the most common complaints I hear when I say I work with zoos is that the animals don’t have as much space as they do in the wild. That is correct: zoos cannot provide the same amount of space for a lot of species. But good quality space can allow these animals to behave like they would in wild habitats.
One of the most controversial animals when talking about space is elephants. In 2017 the UK government issued updated requirements for them which brought in enclosure-size requirements, something that had never happened for any species in British zoos before.
Under the new standards, zoos will have until 2040 to increase their elephant provisions. Indoor space allocation for a herd of up to four females has been doubled to 600m². This then increases by 100m² for each additional elephant (compared to 80m² in the 2017 requirements).
Bull facilities – zoos that house individual male elephants – need to provide 320m² of indoor space per bull. Outdoor areas for bull and cow elephants must provide a minimum shared space of 20,000m² (or 2.8 UK sized football pitches) for up to five group-living adults. This must be increased by at least 2,500m² for each additional animal over two years old. This is over 30 times larger than the current standards.
The new standards stipulate that zoos must provide more natural habitats that better replicate how elephants live in the wild. There are also requirements for more detailed behavioural monitoring and things that help keep elephants active and engaged in their environment.
Howver, animal welfare charity the RSPCA still feels that these updates are not good enough . It believes that elephants (and some other species) are not suitable for captivity as they have complex cognitive needs and space requirements.
From my perspective, Britain has the most specific (and now) welfare-driven standards for elephants in the world. If Britain were to ban the housing of elephants, we would be shipping them to lower quality habitats, care and monitoring. Is this really what we want for the elephants in British zoos?
Another area where there has been much criticism in the past relates to providing animals from specific climates or environments with the correct conditions, such as reptiles, amphibians, tropical birds and primates. While a high number of animals seem to cope well in the UK’s colder climate , there is research to show that some animals need specialised environments, without which they can suffer from severe health problems , low welfare and even death.
The new standards require zoos to develop detailed environmental management plans for species that rely on artificial life-support systems such as aquariums, vivariums , tropical houses or desert habitats. Animals also cannot be removed from their enclosures for interactions or talks with the public.
These environmental management plans outline the environmental parameters required for that animal to thrive and behave naturally, and they need to be monitored to ensure that provisions do not slip.
There are also extra requirements for birds of prey. Although controversial, tethering is currently a recognised management practice for birds of prey, including owls, hawks and falcons. You don’t need to be a welfare scientist to understand how a bird might feel about being tethered to a post for long periods of time.
The 2012 standards stipulated that tethered birds should be flown at least four times per week, though there were no time restrictions on how long they could be tethered. The new standards emphasise that birds can only be tethered for a maximum of four hours in a 24 hour period and only as a management tool that benefits the bird (such as training for flight displays, transportation or veterinary treatment).
There is new emphasis on what is known as behavioural enrichment. Whether it’s puzzle feeders for primates, scent trails for big cats or novel objects for parrots, enrichment helps prevent boredom, reduce stress and promote natural behaviour .
Enrichment can be resource intensive and therefore difficult to implement, but the new standards make it a core requirement. Enrichment activities must aim to replicate natural behaviour such as foraging, climbing or problem solving. Zoos are required to document and evaluate these activities, track how animals respond and adjust strategies accordingly.
These updates reflect a deeper understanding of what animals need to thrive, not just survive. As a zoo welfare scientist, I feel there is always more that can be done to improve the welfare of animals in zoos (such as banning touch pools and tethering altogether).
But it is important that zoos and aquariums evaluate the costs (to the animals) and benefits (to the visitors) to make ethical and welfare-based decisions themselves.
These new standards will improve the conditions for animals in zoos, as well as help zoos to make the right decisions about the animals they house and care for.
