Up to Standard? A Longitudinal Analysis of Regulatory Compliance in British Zoos

Abstract

We analysed the formal inspection reports of 108 licensed British zoos covering three consecutive formal inspections, equivalent to a licensing period, under the Zoo Licensing Act 1981 (ZLA). We examined the compliance of zoos against animal welfare standards, animal escape protocols and engagement in conservation measures, as well as the effects of licence type, zoo association membership, and collection type. Of the 324 inspection reports analysed, 59 (18%) reported that the zoo had passed every assessed question. Failure to undertake the necessary number of escape drills was the most reported area of non-compliance in 134 (41%) of the reports. Across a total of 15,876 welfare assessment criteria, 14,067 (89%) were scored as compliant, but only 83 inspection reports (26%) recorded that the zoo had met all welfare standards. Zoos were commonly found to fall into one of three classes, which predicted their probability of participating in each of the five conservation measures within the ZLA. Farm parks were identified as the collection type performing least well across inspection categories. With British zoos being required to meet new standards from May 2027, we propose a number of changes which could aid inspection consistency and legislative enforcement and drive improvements.
